+What:		/dev/kmsg
+Date:		Mai 2012
+KernelVersion:	3.5
+Contact:	Kay Sievers <kay@vrfy.org>
+Description:	The /dev/kmsg character device node provides userspace access
+		to the kernel's printk buffer.
+
+		Injecting messages:
+		Every write() to the opened device node places a log entry in
+		the kernel's printk buffer.
+
+		The logged line can be prefixed with a <N> syslog prefix, which
+		carries the syslog priority and facility. The single decimal
+		prefix number is composed of the 3 lowest bits being the syslog
+		priority and the higher bits the syslog facility number.
+
+		If no prefix is given, the priority number is the default kernel
+		log priority and the facility number is set to LOG_USER (1). It
+		is not possible to inject messages from userspace with the
+		facility number LOG_KERN (0), to make sure that the origin of
+		the messages can always be reliably determined.
+
+		Accessing the buffer:
+		Every read() from the opened device node receives one record
+		of the kernel's printk buffer.
+
+		The first read() directly following an open() always returns
+		first message in the buffer; there is no kernel-internal
+		persistent state; many readers can concurrently open the device
+		and read from it, without affecting other readers.
+
+		Every read() will receive the next available record. If no more
+		records are available read() will block, or if O_NONBLOCK is
+		used -EAGAIN returned.
+
+		Messages in the record ring buffer get overwritten as whole,
+		there are never partial messages received by read().
+
+		In case messages get overwritten in the circular buffer while
+		the device is kept open, the next read() will return -EPIPE,
+		and the seek position be updated to the next available record.
+		Subsequent reads() will return available records again.
+
+		Unlike the classic syslog() interface, the 64 bit record
+		sequence numbers allow to calculate the amount of lost
+		messages, in case the buffer gets overwritten. And they allow
+		to reconnect to the buffer and reconstruct the read position
+		if needed, without limiting the interface to a single reader.
+
+		The device supports seek with the following parameters:
+		SEEK_SET, 0
+		  seek to the first entry in the buffer
+		SEEK_END, 0
+		  seek after the last entry in the buffer
+		SEEK_DATA, 0
+		  seek after the last record available at the time
+		  the last SYSLOG_ACTION_CLEAR was issued.
+
+		The output format consists of a prefix carrying the syslog
+		prefix including priority and facility, the 64 bit message
+		sequence number and the monotonic timestamp in microseconds.
+		The values are separated by a ','. Future extensions might
+		add more comma separated values before the terminating ';'.
+		Unknown values should be gracefully ignored.
+
+		The human readable text string starts directly after the ';'
+		and is terminated by a '\n'. Untrusted values derived from
+		hardware or other facilities are printed, therefore
+		all non-printable characters in the log message are escaped
+		by "\x00" C-style hex encoding.
+
+		A line starting with ' ', is a continuation line, adding
+		key/value pairs to the log message, which provide the machine
+		readable context of the message, for reliable processing in
+		userspace.
+
+		Example:
+		7,160,424069;pci_root PNP0A03:00: host bridge window [io  0x0000-0x0cf7] (ignored)
+		 SUBSYSTEM=acpi

+		6,339,5140900;NET: Registered protocol family 10
+		30,340,5690716;udevd[80]: starting version 181
+
+		The DEVICE= key uniquely identifies devices the following way:
+		  b12:8        - block dev_t
+		  c127:3       - char dev_t
+		  n8           - netdev ifindex

+What:		/sys/power/autosleep
+Date:		April 2012
+Contact:	Rafael J. Wysocki <rjw@sisk.pl>
+Description:
+		The /sys/power/autosleep file can be written one of the strings
+		returned by reads from /sys/power/state.  If that happens, a
+		work item attempting to trigger a transition of the system to
+		the sleep state represented by that string is queued up.  This
+		attempt will only succeed if there are no active wakeup sources
+		in the system at that time.  After every execution, regardless
+		of whether or not the attempt to put the system to sleep has
+		succeeded, the work item requeues itself until user space
+		writes "off" to /sys/power/autosleep.
+
+		Reading from this file causes the last string successfully

+Date:		February 2012
+Contact:	Rafael J. Wysocki <rjw@sisk.pl>
+Description:
+		The /sys/power/wake_lock file allows user space to create
+		wakeup source objects and activate them on demand (if one of
+		those wakeup sources is active, reads from the
+		/sys/power/wakeup_count file block or return false).  When a
+		string without white space is written to /sys/power/wake_lock,
+		it will be assumed to represent a wakeup source name.  If there
+		is a wakeup source object with that name, it will be activated
+		(unless active already).  Otherwise, a new wakeup source object
+		will be registered, assigned the given name and activated.
+		If a string written to /sys/power/wake_lock contains white
+		space, the part of the string preceding the white space will be
+		regarded as a wakeup source name and handled as descrived above.
+		The other part of the string will be regarded as a timeout (in
+		nanoseconds) such that the wakeup source will be automatically
+		deactivated after it has expired.  The timeout, if present, is
+		set regardless of the current state of the wakeup source object
+		in question.

-Release Notes for Linux on Intel's IXP2000 Network Processor
-
-Maintained by Deepak Saxena <dsaxena@plexity.net>
--------------------------------------------------------------------------
-
-1. Overview
-
-Intel's IXP2000 family of NPUs (IXP2400, IXP2800, IXP2850) is designed
-for high-performance network applications such high-availability
-telecom systems. In addition to an XScale core, it contains up to 8
-"MicroEngines" that run special code, several high-end networking 
-interfaces (UTOPIA, SPI, etc), a PCI host bridge, one serial port,
-flash interface, and some other odds and ends. For more information, see:
-
-http://developer.intel.com
-
-2. Linux Support
-
-Linux currently supports the following features on the IXP2000 NPUs:
-
-- On-chip serial
-- PCI
-- Flash (MTD/JFFS2)
-- I2C through GPIO
-- Timers (watchdog, OS)
-
-That is about all we can support under Linux ATM b/c the core networking
-components of the chip are accessed via Intel's closed source SDK. 
-Please contact Intel directly on issues with using those. There is
-also a mailing list run by some folks at Princeton University that might
-be of help:  https://lists.cs.princeton.edu/mailman/listinfo/ixp2xxx
-
-WHATEVER YOU DO, DO NOT POST EMAIL TO THE LINUX-ARM OR LINUX-ARM-KERNEL
-MAILING LISTS REGARDING THE INTEL SDK.
-
-3. Supported Platforms
-
-- Intel IXDP2400 Reference Platform
-- Intel IXDP2800 Reference Platform
-- Intel IXDP2401 Reference Platform
-- Intel IXDP2801 Reference Platform
-- RadiSys ENP-2611
-
-4. Usage Notes
-
-- The IXP2000 platforms usually have rather complex PCI bus topologies
-  with large memory space requirements. In addition, b/c of the way the
-  Intel SDK is designed, devices are enumerated in a very specific
-  way. B/c of this this, we use "pci=firmware" option in the kernel
-  command line so that we do not re-enumerate the bus.
-
-- IXDP2x01 systems have variable clock tick rates that we cannot determine 
-  via HW registers. The "ixdp2x01_clk=XXX" cmd line options allow you
-  to pass the clock rate to the board port.
-
-5. Thanks
-
-The IXP2000 work has been funded by Intel Corp. and MontaVista Software, Inc.

+* Freescale IOMUX Controller (IOMUXC) for i.MX
+
+The IOMUX Controller (IOMUXC), together with the IOMUX, enables the IC
+to share one PAD to several functional blocks. The sharing is done by
+multiplexing the PAD input/output signals. For each PAD there are up to
+8 muxing options (called ALT modes). Since different modules require
+different PAD settings (like pull up, keeper, etc) the IOMUXC controls
+also the PAD settings parameters.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+Freescale IMX pin configuration node is a node of a group of pins which can be
+used for a specific device or function. This node represents both mux and config
+of the pins in that group. The 'mux' selects the function mode(also named mux
+mode) this pin can work on and the 'config' configures various pad settings
+such as pull-up, open drain, drive strength, etc.
+
+Required properties for iomux controller:
+- compatible: "fsl,<soc>-iomuxc"
+  Please refer to each fsl,<soc>-pinctrl.txt binding doc for supported SoCs.
+
+Required properties for pin configuration node:
+- fsl,pins: two integers array, represents a group of pins mux and config
+  setting. The format is fsl,pins = <PIN_FUNC_ID CONFIG>, PIN_FUNC_ID is a
+  pin working on a specific function, CONFIG is the pad setting value like
+  pull-up on this pin. Please refer to fsl,<soc>-pinctrl.txt for the valid
+  pins and functions of each SoC.
+
+Bits used for CONFIG:
+NO_PAD_CTL(1 << 31): indicate this pin does not need config.
+
+SION(1 << 30): Software Input On Field.
+Force the selected mux mode input path no matter of MUX_MODE functionality.
+By default the input path is determined by functionality of the selected
+mux mode (regular).
+
+Other bits are used for PAD setting.
+Please refer to each fsl,<soc>-pinctrl,txt binding doc for SoC specific part
+of bits definitions.
+
+NOTE:
+Some requirements for using fsl,imx-pinctrl binding:
+1. We have pin function node defined under iomux controller node to represent
+   what pinmux functions this SoC supports.
+2. The pin configuration node intends to work on a specific function should
+   to be defined under that specific function node.
+   The function node's name should represent well about what function
+   this group of pins in this pin configuration node are working on.
+3. The driver can use the function node's name and pin configuration node's
+   name describe the pin function and group hierarchy.
+   For example, Linux IMX pinctrl driver takes the function node's name
+   as the function name and pin configuration node's name as group name to
+   create the map table.
+4. Each pin configuration node should have a phandle, devices can set pins
+   configurations by referring to the phandle of that pin configuration node.
+
+Examples:
+usdhc@0219c000 { /* uSDHC4 */
+	fsl,card-wired;
+	vmmc-supply = <&reg_3p3v>;
+	status = "okay";
+	pinctrl-names = "default";
+	pinctrl-0 = <&pinctrl_usdhc4_1>;
+};
+
+iomuxc@020e0000 {
+	compatible = "fsl,imx6q-iomuxc";
+	reg = <0x020e0000 0x4000>;
+
+	/* shared pinctrl settings */
+	usdhc4 {
+		pinctrl_usdhc4_1: usdhc4grp-1 {
+			fsl,pins = <1386 0x17059	/* MX6Q_PAD_SD4_CMD__USDHC4_CMD */
+				    1392 0x10059	/* MX6Q_PAD_SD4_CLK__USDHC4_CLK	*/

+				    1478 0x17059	/* MX6Q_PAD_SD4_DAT2__USDHC4_DAT2 */
+				    1486 0x17059	/* MX6Q_PAD_SD4_DAT3__USDHC4_DAT3 */
+				    1493 0x17059	/* MX6Q_PAD_SD4_DAT4__USDHC4_DAT4 */
+				    1501 0x17059	/* MX6Q_PAD_SD4_DAT5__USDHC4_DAT5 */

+				    1517 0x17059>;	/* MX6Q_PAD_SD4_DAT7__USDHC4_DAT7 */
+		};
+	};
+	....
+};
+Refer to the IOMUXC controller chapter in imx6q datasheet,
+0x17059 means enable hysteresis, 47KOhm Pull Up, 50Mhz speed,
+80Ohm driver strength and Fast Slew Rate.
+User should refer to each SoC spec to set the correct value.
+
+TODO: when dtc macro support is available, we can change above raw data
+to dt macro which can get better readability in dts file.

+* Freescale MXS Pin Controller
+
+The pins controlled by mxs pin controller are organized in banks, each bank
+has 32 pins.  Each pin has 4 multiplexing functions, and generally, the 4th
+function is GPIO.  The configuration on the pins includes drive strength,
+voltage and pull-up.
+
+Required properties:
+- compatible: "fsl,imx23-pinctrl" or "fsl,imx28-pinctrl"
+- reg: Should contain the register physical address and length for the
+  pin controller.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices.
+
+The node of mxs pin controller acts as a container for an arbitrary number of
+subnodes.  Each of these subnodes represents some desired configuration for
+a group of pins, and only affects those parameters that are explicitly listed.
+In other words, a subnode that describes a drive strength parameter implies no
+information about pull-up. For this reason, even seemingly boolean values are
+actually tristates in this binding: unspecified, off, or on. Unspecified is
+represented as an absent property, and off/on are represented as integer
+values 0 and 1.
+
+Those subnodes under mxs pin controller node will fall into two categories.
+One is to set up a group of pins for a function, both mux selection and pin
+configurations, and it's called group node in the binding document.   The other
+one is to adjust the pin configuration for some particular pins that need a
+different configuration than what is defined in group node.  The binding
+document calls this type of node config node.
+
+On mxs, there is no hardware pin group. The pin group in this binding only
+means a group of pins put together for particular peripheral to work in
+particular function, like SSP0 functioning as mmc0-8bit.  That said, the
+group node should include all the pins needed for one function rather than
+having these pins defined in several group nodes.  It also means each of
+"pinctrl-*" phandle in client device node should only have one group node
+pointed in there, while the phandle can have multiple config node referenced
+there to adjust configurations for some pins in the group.
+
+Required subnode-properties:
+- fsl,pinmux-ids: An integer array.  Each integer in the array specify a pin
+  with given mux function, with bank, pin and mux packed as below.
+
+    [15..12] : bank number
+    [11..4]  : pin number
+    [3..0]   : mux selection
+
+  This integer with mux selection packed is used as an entity by both group
+  and config nodes to identify a pin.  The mux selection in the integer takes
+  effects only on group node, and will get ignored by driver with config node,
+  since config node is only meant to set up pin configurations.
+
+  Valid values for these integers are listed below.
+
+- reg: Should be the index of the group nodes for same function.  This property
+  is required only for group nodes, and should not be present in any config
+  nodes.
+
+Optional subnode-properties:
+- fsl,drive-strength: Integer.
+    0: 4 mA
+    1: 8 mA
+    2: 12 mA
+    3: 16 mA
+- fsl,voltage: Integer.
+    0: 1.8 V
+    1: 3.3 V
+- fsl,pull-up: Integer.
+    0: Disable the internal pull-up
+    1: Enable the internal pull-up
+
+Examples:
+
+pinctrl@80018000 {
+	#address-cells = <1>;
+	#size-cells = <0>;
+	compatible = "fsl,imx28-pinctrl";
+	reg = <0x80018000 2000>;
+
+	mmc0_8bit_pins_a: mmc0-8bit@0 {
+		reg = <0>;
+		fsl,pinmux-ids = <
+			0x2000 0x2010 0x2020 0x2030
+			0x2040 0x2050 0x2060 0x2070
+			0x2080 0x2090 0x20a0>;
+		fsl,drive-strength = <1>;
+		fsl,voltage = <1>;
+		fsl,pull-up = <1>;
+	};
+
+	mmc_cd_cfg: mmc-cd-cfg {
+		fsl,pinmux-ids = <0x2090>;
+		fsl,pull-up = <0>;
+	};
+
+	mmc_sck_cfg: mmc-sck-cfg {
+		fsl,pinmux-ids = <0x20a0>;
+		fsl,drive-strength = <2>;
+		fsl,pull-up = <0>;
+	};
+};
+
+In this example, group node mmc0-8bit defines a group of pins for mxs SSP0
+to function as a 8-bit mmc device, with 8mA, 3.3V and pull-up configurations
+applied on all these pins.  And config nodes mmc-cd-cfg and mmc-sck-cfg are
+adjusting the configuration for pins card-detection and clock from what group
+node mmc0-8bit defines.  Only the configuration properties to be adjusted need
+to be listed in the config nodes.

+NVIDIA Tegra20 pinmux controller
+
+Required properties:
+- compatible: "nvidia,tegra20-pinmux"
+- reg: Should contain the register physical address and length for each of
+  the tri-state, mux, pull-up/down, and pad control register sets.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+Tegra's pin configuration nodes act as a container for an abitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those pin(s)/group(s), and various pin configuration
+parameters, such as pull-up, tristate, drive strength, etc.
+
+The name of each subnode is not important; all subnodes should be enumerated
+and processed purely based on their content.
+
+Each subnode only affects those parameters that are explicitly listed. In
+other words, a subnode that lists a mux function but no pin configuration
+parameters implies no information about any pin configuration parameters.
+Similarly, a pin subnode that describes a pullup parameter implies no
+information about e.g. the mux function or tristate parameter. For this
+reason, even seemingly boolean values are actually tristates in this binding:
+unspecified, off, or on. Unspecified is represented as an absent property,
+and off/on are represented as integer values 0 and 1.
+
+Required subnode-properties:
+- nvidia,pins : An array of strings. Each string contains the name of a pin or
+    group. Valid values for these names are listed below.
+
+Optional subnode-properties:
+- nvidia,function: A string containing the name of the function to mux to the
+  pin or group. Valid values for function names are listed below. See the Tegra
+  TRM to determine which are valid for each pin or group.
+- nvidia,pull: Integer, representing the pull-down/up to apply to the pin.
+    0: none, 1: down, 2: up.
+- nvidia,tristate: Integer.
+    0: drive, 1: tristate.
+- nvidia,high-speed-mode: Integer. Enable high speed mode the pins.
+    0: no, 1: yes.
+- nvidia,schmitt: Integer. Enables Schmitt Trigger on the input.
+    0: no, 1: yes.
+- nvidia,low-power-mode: Integer. Valid values 0-3. 0 is least power, 3 is
+    most power. Controls the drive power or current. See "Low Power Mode"
+    or "LPMD1" and "LPMD0" in the Tegra TRM.
+- nvidia,pull-down-strength: Integer. Controls drive strength. 0 is weakest.
+    The range of valid values depends on the pingroup. See "CAL_DRVDN" in the
+    Tegra TRM.
+- nvidia,pull-up-strength: Integer. Controls drive strength. 0 is weakest.
+    The range of valid values depends on the pingroup. See "CAL_DRVUP" in the
+    Tegra TRM.
+- nvidia,slew-rate-rising: Integer. Controls rising signal slew rate. 0 is
+    fastest. The range of valid values depends on the pingroup. See
+    "DRVDN_SLWR" in the Tegra TRM.
+- nvidia,slew-rate-falling: Integer. Controls falling signal slew rate. 0 is
+    fastest. The range of valid values depends on the pingroup. See
+    "DRVUP_SLWF" in the Tegra TRM.
+
+Note that many of these properties are only valid for certain specific pins
+or groups. See the Tegra TRM and various pinmux spreadsheets for complete
+details regarding which groups support which functionality. The Linux pinctrl
+driver may also be a useful reference, since it consolidates, disambiguates,
+and corrects data from all those sources.
+
+Valid values for pin and group names are:
+
+  mux groups:
+
+    These all support nvidia,function, nvidia,tristate, and many support
+    nvidia,pull.

+NVIDIA Tegra30 pinmux controller
+
+The Tegra30 pinctrl binding is very similar to the Tegra20 pinctrl binding,
+as described in nvidia,tegra20-pinmux.txt. In fact, this document assumes
+that binding as a baseline, and only documents the differences between the
+two bindings.
+
+Required properties:
+- compatible: "nvidia,tegra30-pinmux"
+- reg: Should contain the register physical address and length for each of
+  the pad control and mux registers.
+
+Tegra30 adds the following optional properties for pin configuration subnodes:
+- nvidia,enable-input: Integer. Enable the pin's input path. 0: no, 1: yes.
+- nvidia,open-drain: Integer. Enable open drain mode. 0: no, 1: yes.
+- nvidia,lock: Integer. Lock the pin configuration against further changes
+    until reset. 0: no, 1: yes.
+- nvidia,io-reset: Integer. Reset the IO path. 0: no, 1: yes.
+
+As with Tegra20, see the Tegra TRM for complete details regarding which groups
+support which functionality.
+
+Valid values for pin and group names are:
+
+  per-pin mux groups:
+
+    These all support nvidia,function, nvidia,tristate, nvidia,pull,
+    nvidia,enable-input, nvidia,lock. Some support nvidia,open-drain,
+    nvidia,io-reset.

+== Introduction ==
+
+Hardware modules that control pin multiplexing or configuration parameters
+such as pull-up/down, tri-state, drive-strength etc are designated as pin
+controllers. Each pin controller must be represented as a node in device tree,
+just like any other hardware module.
+
+Hardware modules whose signals are affected by pin configuration are
+designated client devices. Again, each client device must be represented as a
+node in device tree, just like any other hardware module.
+
+For a client device to operate correctly, certain pin controllers must
+set up certain specific pin configurations. Some client devices need a
+single static pin configuration, e.g. set up during initialization. Others
+need to reconfigure pins at run-time, for example to tri-state pins when the
+device is inactive. Hence, each client device can define a set of named
+states. The number and names of those states is defined by the client device's
+own binding.
+
+The common pinctrl bindings defined in this file provide an infrastructure
+for client device device tree nodes to map those state names to the pin
+configuration used by those states.
+
+Note that pin controllers themselves may also be client devices of themselves.
+For example, a pin controller may set up its own "active" state when the
+driver loads. This would allow representing a board's static pin configuration
+in a single place, rather than splitting it across multiple client device
+nodes. The decision to do this or not somewhat rests with the author of
+individual board device tree files, and any requirements imposed by the
+bindings for the individual client devices in use by that board, i.e. whether
+they require certain specific named states for dynamic pin configuration.
+
+== Pinctrl client devices ==
+
+For each client device individually, every pin state is assigned an integer
+ID. These numbers start at 0, and are contiguous. For each state ID, a unique
+property exists to define the pin configuration. Each state may also be
+assigned a name. When names are used, another property exists to map from
+those names to the integer IDs.
+
+Each client device's own binding determines the set of states the must be
+defined in its device tree node, and whether to define the set of state
+IDs that must be provided, or whether to define the set of state names that
+must be provided.
+
+Required properties:
+pinctrl-0:	List of phandles, each pointing at a pin configuration
+		node. These referenced pin configuration nodes must be child
+		nodes of the pin controller that they configure. Multiple
+		entries may exist in this list so that multiple pin
+		controllers may be configured, or so that a state may be built
+		from multiple nodes for a single pin controller, each
+		contributing part of the overall configuration. See the next
+		section of this document for details of the format of these
+		pin configuration nodes.
+
+		In some cases, it may be useful to define a state, but for it
+		to be empty. This may be required when a common IP block is
+		used in an SoC either without a pin controller, or where the
+		pin controller does not affect the HW module in question. If
+		the binding for that IP block requires certain pin states to
+		exist, they must still be defined, but may be left empty.
+
+Optional properties:
+pinctrl-1:	List of phandles, each pointing at a pin configuration
+		node within a pin controller.
+...
+pinctrl-n:	List of phandles, each pointing at a pin configuration
+		node within a pin controller.
+pinctrl-names:	The list of names to assign states. List entry 0 defines the
+		name for integer state ID 0, list entry 1 for state ID 1, and
+		so on.
+
+For example:
+
+	/* For a client device requiring named states */
+	device {
+		pinctrl-names = "active", "idle";
+		pinctrl-0 = <&state_0_node_a>;
+		pinctrl-1 = <&state_1_node_a &state_1_node_b>;
+	};
+
+	/* For the same device if using state IDs */
+	device {
+		pinctrl-0 = <&state_0_node_a>;
+		pinctrl-1 = <&state_1_node_a &state_1_node_b>;
+	};
+
+	/*
+	 * For an IP block whose binding supports pin configuration,
+	 * but in use on an SoC that doesn't have any pin control hardware
+	 */
+	device {
+		pinctrl-names = "active", "idle";
+		pinctrl-0 = <>;
+		pinctrl-1 = <>;
+	};
+
+== Pin controller devices ==
+
+Pin controller devices should contain the pin configuration nodes that client
+devices reference.
+
+For example:
+
+	pincontroller {
+		... /* Standard DT properties for the device itself elided */
+
+		state_0_node_a {
+			...
+		};
+		state_1_node_a {
+			...
+		};
+		state_1_node_b {
+			...
+		};
+	}
+
+The contents of each of those pin configuration child nodes is defined
+entirely by the binding for the individual pin controller device. There
+exists no common standard for this content.
+
+The pin configuration nodes need not be direct children of the pin controller
+device; they may be grandchildren, for example. Whether this is legal, and
+whether there is any interaction between the child and intermediate parent
+nodes, is again defined entirely by the binding for the individual pin
+controller device.

 Controlling dynamic debug Behaviour

+Debug messages during Boot Process
 ==================================
 
-To be able to activate debug messages during the boot process,
-even before userspace and debugfs exists, use the boot parameter:
-ddebug_query="QUERY"
+To activate debug messages for core code and built-in modules during
+the boot process, even before userspace and debugfs exists, use
+dyndbg="QUERY", module.dyndbg="QUERY", or ddebug_query="QUERY"
+(ddebug_query is obsoleted by dyndbg, and deprecated).  QUERY follows
+the syntax described above, but must not exceed 1023 characters.  Your
+bootloader may impose lower limits.
+
+These dyndbg params are processed just after the ddebug tables are
+processed, as part of the arch_initcall.  Thus you can enable debug
+messages in all code run after this arch_initcall via this boot
+parameter.
 
-QUERY follows the syntax described above, but must not exceed 1023
-characters. The enablement of debug messages is done as an arch_initcall.
-Thus you can enable debug messages in all code processed after this
-arch_initcall via this boot parameter.
 On an x86 system for example ACPI enablement is a subsys_initcall and
-ddebug_query="file ec.c +p"
+   dyndbg="file ec.c +p"
 will show early Embedded Controller transactions during ACPI setup if
 your machine (typically a laptop) has an Embedded Controller.
 PCI (or other devices) initialization also is a hot candidate for using
 this boot parameter for debugging purposes.
 
+If foo module is not built-in, foo.dyndbg will still be processed at
+boot time, without effect, but will be reprocessed when module is
+loaded later.  dyndbg_query= and bare dyndbg= are only processed at
+boot.
+
+
+Debug Messages at Module Initialization Time
+============================================
+
+When "modprobe foo" is called, modprobe scans /proc/cmdline for
+foo.params, strips "foo.", and passes them to the kernel along with
+params given in modprobe args or /etc/modprob.d/*.conf files,
+in the following order:
+
+1. # parameters given via /etc/modprobe.d/*.conf
+   options foo dyndbg=+pt
+   options foo dyndbg # defaults to +p
+
+2. # foo.dyndbg as given in boot args, "foo." is stripped and passed
+   foo.dyndbg=" func bar +p; func buz +mp"
+
+3. # args to modprobe
+   modprobe foo dyndbg==pmf # override previous settings
+
+These dyndbg queries are applied in order, with last having final say.
+This allows boot args to override or modify those from /etc/modprobe.d
+(sensible, since 1 is system wide, 2 is kernel or boot specific), and
+modprobe args to override both.
+
+In the foo.dyndbg="QUERY" form, the query must exclude "module foo".
+"foo" is extracted from the param-name, and applied to each query in
+"QUERY", and only 1 match-spec of each type is allowed.
+
+The dyndbg option is a "fake" module parameter, which means:
+
+- modules do not need to define it explicitly
+- every module gets it tacitly, whether they use pr_debug or not
+- it doesnt appear in /sys/module/$module/parameters/
+  To see it, grep the control file, or inspect /proc/cmdline.
+
+For CONFIG_DYNAMIC_DEBUG kernels, any settings given at boot-time (or
+enabled by -DDEBUG flag during compilation) can be disabled later via
+the sysfs interface if the debug messages are no longer needed:
+
+   echo "module module_name -p" > <debugfs>/dynamic_debug/control

+ * CHAPTER 1.                                                    *
+ * PORTING SWITCH CLASS DEVICE DRIVERS                           *
+ *****************************************************************/
+
+****** STEP 1. Basic Functionality
+	No extcon extended feature, but switch features only.
+
+- struct switch_dev (fed to switch_dev_register/unregister)
+    @name: no change
+    @dev: no change
+    @index: drop (not used in switch device driver side anyway)
+    @state: no change
+	If you have used @state with magic numbers, keep it
+	at this step.
+    @print_name: no change but type change (switch_dev->extcon_dev)
+    @print_state: no change but type change (switch_dev->extcon_dev)
+
+- switch_dev_register(sdev, dev)
+	=> extcon_dev_register(edev, dev)
+	: no change but type change (sdev->edev)
+- switch_dev_unregister(sdev)
+	=> extcon_dev_unregister(edev)
+	: no change but type change (sdev->edev)
+- switch_get_state(sdev)
+	=> extcon_get_state(edev)
+	: no change but type change (sdev->edev) and (return: int->u32)
+- switch_set_state(sdev, state)
+	=> extcon_set_state(edev, state)
+	: no change but type change (sdev->edev) and (state: int->u32)
+
+With this changes, the ex-switch extcon class device works as it once
+worked as switch class device. However, it will now have additional
+interfaces (both ABI and in-kernel API) and different ABI locations.
+However, if CONFIG_ANDROID is enabled without CONFIG_ANDROID_SWITCH,
+/sys/class/switch/* will be symbolically linked to /sys/class/extcon/
+so that they are still compatible with legacy userspace processes.
+
+****** STEP 2. Multistate (no more magic numbers in state value)
+	Extcon's extended features for switch device drivers with
+	complex features usually required magic numbers in state
+	value of switch_dev. With extcon, such magic numbers that
+	support multiple cables (
+
+  1. Define cable names at edev->supported_cable.
+  2. (Recommended) remove print_state callback.
+  3. Use extcon_get_cable_state_(edev, index) or
+   extcon_get_cable_state(edev, cable_name) instead of
+   extcon_get_state(edev) if you intend to get a state of a specific
+   cable. Same for set_state. This way, you can remove the usage of
+   magic numbers in state value.
+  4. Use extcon_update_state() if you are updating specific bits of
+   the state value.
+
+Example: a switch device driver w/ magic numbers for two cables.
+	"0x00": no cables connected.
+	"0x01": cable 1 connected
+	"0x02": cable 2 connected
+	"0x03": cable 1 and 2 connected
+  1. edev->supported_cable = {"1", "2", NULL};
+  2. edev->print_state = NULL;
+  3. extcon_get_cable_state_(edev, 0) shows cable 1's state.
+     extcon_get_cable_state(edev, "1") shows cable 1's state.
+     extcon_set_cable_state_(edev, 1) sets cable 2's state.
+     extcon_set_cable_state(edev, "2") sets cable 2's state
+  4. extcon_update_state(edev, 0x01, 0) sets the least bit's 0.
+
+****** STEP 3. Notify other device drivers
+
+  You can notify others of the cable attach/detach events with
+notifier chains.
+
+  At the side of other device drivers (the extcon device itself
+does not need to get notified of its own events), there are two
+methods to register notifier_block for cable events:
+(a) for a specific cable or (b) for every cable.
+
+  (a) extcon_register_interest(obj, extcon_name, cable_name, nb)
+	Example: want to get news of "MAX8997_MUIC"'s "USB" cable
+
+	obj = kzalloc(sizeof(struct extcon_specific_cable_nb),
+		      GFP_KERNEL);
+	nb->notifier_call = the_callback_to_handle_usb;
+
+	extcon_register_intereset(obj, "MAX8997_MUIC", "USB", nb);
+
+  (b) extcon_register_notifier(edev, nb)
+	Call nb for any changes in edev.
+
+  Please note that in order to properly behave with method (a),
+the extcon device driver should support multistate feature (STEP 2).
+
+****** STEP 4. Inter-cable relation (mutually exclusive)
+
+  You can provide inter-cable mutually exclusiveness information
+for an extcon device. When cables A and B are declared to be mutually
+exclusive, the two cables cannot be in ATTACHED state simulteneously.
+
+
+/*****************************************************************
+ * CHAPTER 2.                                                    *
+ * PORTING USERSPACE w/ SWITCH CLASS DEVICE SUPPORT              *
+ *****************************************************************/
+
+****** ABI Location
+
+  If "CONFIG_ANDROID" is enabled and "CONFIG_ANDROID_SWITCH" is
+disabled, /sys/class/switch/* are created as symbolic links to
+/sys/class/extcon/*. Because CONFIG_ANDROID_SWITCH creates
+/sys/class/switch directory, we disable symboling linking if
+CONFIG_ANDROID_SWITCH is enabled.
+
+  The two files of switch class, name and state, are provided with
+extcon, too. When the multistate support (STEP 2 of CHAPTER 1.) is
+not enabled or print_state callback is supplied, the output of
+state ABI is same with switch class.

+                            Glock Statistics
+                           ------------------
+
+The stats are divided into two sets: those relating to the
+super block and those relating to an individual glock. The
+super block stats are done on a per cpu basis in order to
+try and reduce the overhead of gathering them. They are also
+further divided by glock type. All timings are in nanoseconds.
+
+In the case of both the super block and glock statistics,
+the same information is gathered in each case. The super
+block timing statistics are used to provide default values for
+the glock timing statistics, so that newly created glocks
+should have, as far as possible, a sensible starting point.
+The per-glock counters are initialised to zero when the
+glock is created. The per-glock statistics are lost when
+the glock is ejected from memory.
+
+The statistics are divided into three pairs of mean and
+variance, plus two counters. The mean/variance pairs are
+smoothed exponential estimates and the algorithm used is
+one which will be very familiar to those used to calculation
+of round trip times in network code. See "TCP/IP Illustrated,
+Volume 1", W. Richard Stevens, sect 21.3, "Round-Trip Time Measurement",
+p. 299 and onwards. Also, Volume 2, Sect. 25.10, p. 838 and onwards.
+Unlike the TCP/IP Illustrated case, the mean and variance are
+not scaled, but are in units of integer nanoseconds.
+
+The three pairs of mean/variance measure the following
+things:
+
+ 1. DLM lock time (non-blocking requests)
+ 2. DLM lock time (blocking requests)
+ 3. Inter-request time (again to the DLM)
+
+A non-blocking request is one which will complete right
+away, whatever the state of the DLM lock in question. That
+currently means any requests when (a) the current state of
+the lock is exclusive, i.e. a lock demotion (b) the requested
+state is either null or unlocked (again, a demotion) or (c) the
+"try lock" flag is set. A blocking request covers all the other
+lock requests.
+
+There are two counters. The first is there primarily to show
+how many lock requests have been made, and thus how much data
+has gone into the mean/variance calculations. The other counter
+is counting queuing of holders at the top layer of the glock
+code. Hopefully that number will be a lot larger than the number
+of dlm lock requests issued.
+
+So why gather these statistics? There are several reasons
+we'd like to get a better idea of these timings:
+
+1. To be able to better set the glock "min hold time"
+2. To spot performance issues more easily
+3. To improve the algorithm for selecting resource groups for
+allocation (to base it on lock wait time, rather than blindly
+using a "try lock")
+
+Due to the smoothing action of the updates, a step change in
+some input quantity being sampled will only fully be taken
+into account after 8 samples (or 4 for the variance) and this
+needs to be carefully considered when interpreting the
+results.
+
+Knowing both the time it takes a lock request to complete and
+the average time between lock requests for a glock means we
+can compute the total percentage of the time for which the
+node is able to use a glock vs. time that the rest of the
+cluster has its share. That will be very useful when setting
+the lock min hold time.
+
+Great care has been taken to ensure that we
+measure exactly the quantities that we want, as accurately
+as possible. There are always inaccuracies in any
+measuring system, but I hope this is as accurate as we
+can reasonably make it.
+
+Per sb stats can be found here:
+/sys/kernel/debug/gfs2/<fsname>/sbstats
+Per glock stats can be found here:
+/sys/kernel/debug/gfs2/<fsname>/glstats
+
+Assuming that debugfs is mounted on /sys/kernel/debug and also
+that <fsname> is replaced with the name of the gfs2 filesystem
+in question.
+
+The abbreviations used in the output as are follows:
+
+srtt     - Smoothed round trip time for non-blocking dlm requests
+srttvar  - Variance estimate for srtt
+srttb    - Smoothed round trip time for (potentially) blocking dlm requests
+srttvarb - Variance estimate for srttb
+sirt     - Smoothed inter-request time (for dlm requests)
+sirtvar  - Variance estimate for sirt
+dlm      - Number of dlm requests made (dcnt in glstats file)
+queue    - Number of glock requests queued (qcnt in glstats file)
+
+The sbstats file contains a set of these stats for each glock type (so 8 lines
+for each type) and for each cpu (one column per cpu). The glstats file contains
+a set of these stats for each glock in a similar format to the glocks file, but
+using the format mean/variance for each of the timing stats.
+
+The gfs2_glock_lock_time tracepoint prints out the current values of the stats
+for the glock in question, along with some addition information on each dlm

+		Texas Instruments EMIF driver
+
+Description
+===========
+This driver is for the EMIF module available in Texas Instruments
+SoCs. EMIF is an SDRAM controller that, based on its revision,
+supports one or more of DDR2, DDR3, and LPDDR2 SDRAM protocols.
+This driver takes care of only LPDDR2 memories presently. The
+functions of the driver includes re-configuring AC timing
+parameters and other settings during frequency, voltage and
+temperature changes
+
+Platform Data (see include/linux/platform_data/emif_plat.h):
+=====================================================================
+DDR device details and other board dependent and SoC dependent
+information can be passed through platform data (struct emif_platform_data)
+- DDR device details: 'struct ddr_device_info'
+- Device AC timings: 'struct lpddr2_timings' and 'struct lpddr2_min_tck'
+- Custom configurations: customizable policy options through
+  'struct emif_custom_configs'
+- IP revision
+- PHY type
+
+Interface to the external world:
+================================
+EMIF driver registers notifiers for voltage and frequency changes
+affecting EMIF and takes appropriate actions when these are invoked.
+- freq_pre_notify_handling()
+- freq_post_notify_handling()
+- volt_notify_handling()
+
+Debugfs
+========
+The driver creates two debugfs entries per device.
+- regcache_dump : dump of register values calculated and saved for all
+  frequencies used so far.
+- mr4 : last polled value of MR4 register in the LPDDR2 device. MR4
+  indicates the current temperature level of the device.

+		SECure COMPuting with filters
+		=============================
+
+Introduction
+------------
+
+A large number of system calls are exposed to every userland process
+with many of them going unused for the entire lifetime of the process.
+As system calls change and mature, bugs are found and eradicated.  A
+certain subset of userland applications benefit by having a reduced set
+of available system calls.  The resulting set reduces the total kernel
+surface exposed to the application.  System call filtering is meant for
+use with those applications.
+
+Seccomp filtering provides a means for a process to specify a filter for
+incoming system calls.  The filter is expressed as a Berkeley Packet
+Filter (BPF) program, as with socket filters, except that the data
+operated on is related to the system call being made: system call
+number and the system call arguments.  This allows for expressive
+filtering of system calls using a filter program language with a long
+history of being exposed to userland and a straightforward data set.
+
+Additionally, BPF makes it impossible for users of seccomp to fall prey
+to time-of-check-time-of-use (TOCTOU) attacks that are common in system
+call interposition frameworks.  BPF programs may not dereference
+pointers which constrains all filters to solely evaluating the system
+call arguments directly.
+
+What it isn't
+-------------
+
+System call filtering isn't a sandbox.  It provides a clearly defined
+mechanism for minimizing the exposed kernel surface.  It is meant to be
+a tool for sandbox developers to use.  Beyond that, policy for logical
+behavior and information flow should be managed with a combination of
+other system hardening techniques and, potentially, an LSM of your
+choosing.  Expressive, dynamic filters provide further options down this
+path (avoiding pathological sizes or selecting which of the multiplexed
+system calls in socketcall() is allowed, for instance) which could be
+construed, incorrectly, as a more complete sandboxing solution.
+
+Usage
+-----
+
+An additional seccomp mode is added and is enabled using the same
+prctl(2) call as the strict seccomp.  If the architecture has
+CONFIG_HAVE_ARCH_SECCOMP_FILTER, then filters may be added as below:
+
+PR_SET_SECCOMP:
+	Now takes an additional argument which specifies a new filter
+	using a BPF program.
+	The BPF program will be executed over struct seccomp_data
+	reflecting the system call number, arguments, and other
+	metadata.  The BPF program must then return one of the
+	acceptable values to inform the kernel which action should be
+	taken.
+
+	Usage:
+		prctl(PR_SET_SECCOMP, SECCOMP_MODE_FILTER, prog);
+
+	The 'prog' argument is a pointer to a struct sock_fprog which
+	will contain the filter program.  If the program is invalid, the
+	call will return -1 and set errno to EINVAL.
+
+	If fork/clone and execve are allowed by @prog, any child
+	processes will be constrained to the same filters and system
+	call ABI as the parent.
+
+	Prior to use, the task must call prctl(PR_SET_NO_NEW_PRIVS, 1) or
+	run with CAP_SYS_ADMIN privileges in its namespace.  If these are not
+	true, -EACCES will be returned.  This requirement ensures that filter
+	programs cannot be applied to child processes with greater privileges
+	than the task that installed them.
+
+	Additionally, if prctl(2) is allowed by the attached filter,
+	additional filters may be layered on which will increase evaluation
+	time, but allow for further decreasing the attack surface during
+	execution of a process.
+
+The above call returns 0 on success and non-zero on error.
+
+Return values
+-------------
+A seccomp filter may return any of the following values. If multiple
+filters exist, the return value for the evaluation of a given system
+call will always use the highest precedent value. (For example,
+SECCOMP_RET_KILL will always take precedence.)
+
+In precedence order, they are:
+
+SECCOMP_RET_KILL:
+	Results in the task exiting immediately without executing the
+	system call.  The exit status of the task (status & 0x7f) will
+	be SIGSYS, not SIGKILL.
+
+SECCOMP_RET_TRAP:
+	Results in the kernel sending a SIGSYS signal to the triggering
+	task without executing the system call.  The kernel will
+	rollback the register state to just before the system call
+	entry such that a signal handler in the task will be able to
+	inspect the ucontext_t->uc_mcontext registers and emulate
+	system call success or failure upon return from the signal
+	handler.
+
+	The SECCOMP_RET_DATA portion of the return value will be passed
+	as si_errno.
+
+	SIGSYS triggered by seccomp will have a si_code of SYS_SECCOMP.
+
+SECCOMP_RET_ERRNO:
+	Results in the lower 16-bits of the return value being passed
+	to userland as the errno without executing the system call.
+
+SECCOMP_RET_TRACE:
+	When returned, this value will cause the kernel to attempt to
+	notify a ptrace()-based tracer prior to executing the system
+	call.  If there is no tracer present, -ENOSYS is returned to
+	userland and the system call is not executed.
+
+	A tracer will be notified if it requests PTRACE_O_TRACESECCOMP
+	using ptrace(PTRACE_SETOPTIONS).  The tracer will be notified
+	of a PTRACE_EVENT_SECCOMP and the SECCOMP_RET_DATA portion of
+	the BPF program return value will be available to the tracer
+	via PTRACE_GETEVENTMSG.
+
+SECCOMP_RET_ALLOW:
+	Results in the system call being executed.
+
+If multiple filters exist, the return value for the evaluation of a
+given system call will always use the highest precedent value.
+
+Precedence is only determined using the SECCOMP_RET_ACTION mask.  When
+multiple filters return values of the same precedence, only the
+SECCOMP_RET_DATA from the most recently installed filter will be
+returned.
+
+Pitfalls
+--------
+
+The biggest pitfall to avoid during use is filtering on system call
+number without checking the architecture value.  Why?  On any
+architecture that supports multiple system call invocation conventions,
+the system call numbers may vary based on the specific invocation.  If
+the numbers in the different calling conventions overlap, then checks in
+the filters may be abused.  Always check the arch value!
+
+Example
+-------
+
+The samples/seccomp/ directory contains both an x86-specific example
+and a more generic example of a higher level macro interface for BPF
+program generation.
+
+
+
+Adding architecture support
+-----------------------
+
+See arch/Kconfig for the authoritative requirements.  In general, if an
+architecture supports both ptrace_event and seccomp, it will be able to
+support seccomp filter with minor fixup: SIGSYS support and seccomp return
+value checking.  Then it must just add CONFIG_HAVE_ARCH_SECCOMP_FILTER
+to its arch-specific Kconfig.

-Smack uses extended attributes (xattrs) to store file labels.
-The command to set a Smack label on a file is:
+Smack uses extended attributes (xattrs) to store labels on filesystem
+objects. The attributes are stored in the extended attribute security
+name space. A process must have CAP_MAC_ADMIN to change any of these
+attributes.
+
+The extended attributes that Smack uses are:
+
+SMACK64
+	Used to make access control decisions. In almost all cases
+	the label given to a new filesystem object will be the label
+	of the process that created it.
+SMACK64EXEC
+	The Smack label of a process that execs a program file with
+	this attribute set will run with this attribute's value.
+SMACK64MMAP
+	Don't allow the file to be mmapped by a process whose Smack
+	label does not allow all of the access permitted to a process
+	with the label contained in this attribute. This is a very
+	specific use case for shared libraries.
+SMACK64TRANSMUTE
+	Can only have the value "TRUE". If this attribute is present
+	on a directory when an object is created in the directory and
+	the Smack rule (more below) that permitted the write access
+	to the directory includes the transmute ("t") mode the object
+	gets the label of the directory instead of the label of the
+	creating process. If the object being created is a directory
+	the SMACK64TRANSMUTE attribute is set as well.
+SMACK64IPIN
+	This attribute is only available on file descriptors for sockets.
+	Use the Smack label in this attribute for access control
+	decisions on packets being delivered to this socket.
+SMACK64IPOUT
+	This attribute is only available on file descriptors for sockets.
+	Use the Smack label in this attribute for access control
+	decisions on packets coming from this socket.
+
+There are multiple ways to set a Smack label on a file:
 
     # attr -S -s SMACK64 -V "value" path
+    # chsmack -a value path
 
-NOTE: Smack labels are limited to 23 characters. The attr command
-      does not enforce this restriction and can be used to set
-      invalid Smack labels on files.
-
-If you don't do anything special all users will get the floor ("_")
-label when they log in. If you do want to log in via the hacked ssh
-at other labels use the attr command to set the smack value on the
-home directory and its contents.
+A process can see the smack label it is running with by
+reading /proc/self/attr/current. A process with CAP_MAC_ADMIN

-BTFIXUP
--------
-
-To build new kernels you have to issue "make image". The ready kernel
-in ELF format is placed in arch/sparc/boot/image. Explanation is below.
-
-BTFIXUP is a unique feature of Linux/sparc among other architectures,
-developed by Jakub Jelinek (I think... Obviously David S. Miller took
-part, too). It allows to boot the same kernel at different 
-sub-architectures, such as sun4c, sun4m, sun4d, where SunOS uses
-different kernels. This feature is convinient for people who you move
-disks between boxes and for distrution builders.
-
-To function, BTFIXUP must link the kernel "in the draft" first,
-analyze the result, write a special stub code based on that, and
-build the final kernel with the stub (btfix.o).
-
-Kai Germaschewski improved the build system of the kernel in the 2.5 series
-significantly. Unfortunately, the traditional way of running the draft
-linking from architecture specific Makefile before the actual linking
-by generic Makefile is nearly impossible to support properly in the
-new build system. Therefore, the way we integrate BTFIXUP with the
-build system was changed in 2.5.40. Now, generic Makefile performs
-the draft linking and stores the result in file vmlinux. Architecture
-specific post-processing invokes BTFIXUP machinery and final linking
-in the same way as other architectures do bootstraps.
-
-Implications of that change are as follows.
-
-1. Hackers must type "make image" now, instead of just "make", in the same
-   way as s390 people do now. It is analogous to "make bzImage" on i386.
-   This does NOT affect sparc64, you continue to use "make" to build sparc64
-   kernels.
-
-2. vmlinux is not the final kernel, so RPM builders have to adjust
-   their spec files (if they delivered vmlinux for debugging).
-   System.map generated for vmlinux is still valid.
-
-3. Scripts that produce a.out images have to be changed. First, if they
-   invoke make, they have to use "make image". Second, they have to pick up
-   the new kernel in arch/sparc/boot/image instead of vmlinux.
-
-4. Since we are compliant with Kai's build system now, make -j is permitted.

+*How FunctionFS works*
+
+From kernel point of view it is just a composite function with some
+unique behaviour.  It may be added to an USB configuration only after
+the user space driver has registered by writing descriptors and
+strings (the user space program has to provide the same information
+that kernel level composite functions provide when they are added to
+the configuration).
+
+This in particular means that the composite initialisation functions
+may not be in init section (ie. may not use the __init tag).
+
+From user space point of view it is a file system which when
+mounted provides an "ep0" file.  User space driver need to
+write descriptors and strings to that file.  It does not need
+to worry about endpoints, interfaces or strings numbers but
+simply provide descriptors such as if the function was the
+only one (endpoints and strings numbers starting from one and
+interface numbers starting from zero).  The FunctionFS changes
+them as needed also handling situation when numbers differ in
+different configurations.
+
+When descriptors and strings are written "ep#" files appear
+(one for each declared endpoint) which handle communication on
+a single endpoint.  Again, FunctionFS takes care of the real
+numbers and changing of the configuration (which means that
+"ep1" file may be really mapped to (say) endpoint 3 (and when
+configuration changes to (say) endpoint 2)).  "ep0" is used
+for receiving events and handling setup requests.
+
+When all files are closed the function disables itself.
+
+What I also want to mention is that the FunctionFS is designed in such
+a way that it is possible to mount it several times so in the end
+a gadget could use several FunctionFS functions. The idea is that
+each FunctionFS instance is identified by the device name used
+when mounting.
+
+One can imagine a gadget that has an Ethernet, MTP and HID interfaces
+where the last two are implemented via FunctionFS.  On user space
+level it would look like this:
+
+$ insmod g_ffs.ko idVendor=<ID> iSerialNumber=<string> functions=mtp,hid
+$ mkdir /dev/ffs-mtp && mount -t functionfs mtp /dev/ffs-mtp
+$ ( cd /dev/ffs-mtp && mtp-daemon ) &
+$ mkdir /dev/ffs-hid && mount -t functionfs hid /dev/ffs-hid
+$ ( cd /dev/ffs-hid && hid-daemon ) &
+
+On kernel level the gadget checks ffs_data->dev_name to identify
+whether it's FunctionFS designed for MTP ("mtp") or HID ("hid").
+
+If no "functions" module parameters is supplied, the driver accepts
+just one function with any name.
+
+When "functions" module parameter is supplied, only functions
+with listed names are accepted. In particular, if the "functions"
+parameter's value is just a one-element list, then the behaviour
+is similar to when there is no "functions" at all; however,
+only a function with the specified name is accepted.
+
+The gadget is registered only after all the declared function
+filesystems have been mounted and USB descriptors of all functions
+have been written to their ep0's.
+
+Conversely, the gadget is unregistered after the first USB function
+closes its endpoints.

+Appendix I: SCSI Host Device
+
+The virtio SCSI host device groups together one or more virtual
+logical units (such as disks), and allows communicating to them
+using the SCSI protocol. An instance of the device represents a
+SCSI host to which many targets and LUNs are attached.
+
+The virtio SCSI device services two kinds of requests:
+
+  command requests for a logical unit;
+
+  task management functions related to a logical unit, target or
+  command.
+
+The device is also able to send out notifications about added and
+removed logical units. Together, these capabilities provide a
+SCSI transport protocol that uses virtqueues as the transfer
+medium. In the transport protocol, the virtio driver acts as the
+initiator, while the virtio SCSI host provides one or more
+targets that receive and process the requests.

+  num_queues is the total number of request virtqueues exposed by

+
+  seg_max is the maximum number of segments that can be in a

+    segments and seg_max output segments.
+
+  max_sectors is a hint to the guest about the maximum transfer
+    size it should use.
+
+  cmd_per_lun is a hint to the guest about the maximum number of
+    linked commands it should send to one LUN. The actual value
+    to be used is the minimum of cmd_per_lun and the virtqueue
+    size.
+
+  event_info_size is the maximum size that the device will fill

+

+The lun field addresses a target and logical unit in the
+virtio-scsi device's SCSI domain. The only supported format for
+the LUN field is: first byte set to 1, second byte set to target,
+third and fourth byte representing a single level LUN structure,
+followed by four zero bytes. With this representation, a
+virtio-scsi device can serve up to 256 targets and 16384 LUNs per
+target.
+
+The id field is the command identifier (“tag”).
+
+task_attr, prio and crn should be left to zero. task_attr defines
+the task attribute as in the table above, but all task attributes
+may be mapped to SIMPLE by the device; crn may also be provided
+by clients, but is generally expected to be 0. The maximum CRN
+value defined by the protocol is 255, since CRN is stored in an
+8-bit integer.
+
+All of these fields are defined in SAM. They are always
+read-only, as are the cdb and dataout field. The cdb_size is
+taken from the configuration space.
+
+sense and subsequent fields are always write-only. The sense_len
+field indicates the number of bytes actually written to the sense
+buffer. The residual field indicates the residual size,
+calculated as “data_length - number_of_transferred_bytes”, for
+read or write operations. For bidirectional commands, the
+number_of_transferred_bytes includes both read and written bytes.
+A residual field that is less than the size of datain means that
+the dataout field was processed entirely. A residual field that
+exceeds the size of datain means that the dataout field was
+processed partially and the datain field was not processed at
+all.
+
+The status byte is written by the device to be the status code as
+defined in SAM.
+
+The response byte is written by the device to be one of the
+following:
+
+  VIRTIO_SCSI_S_OK when the request was completed and the status
+  byte is filled with a SCSI status code (not necessarily
+  "GOOD").
+
+  VIRTIO_SCSI_S_OVERRUN if the content of the CDB requires
+  transferring more data than is available in the data buffers.
+
+  VIRTIO_SCSI_S_ABORTED if the request was cancelled due to an
+  ABORT TASK or ABORT TASK SET task management function.
+
+  VIRTIO_SCSI_S_BAD_TARGET if the request was never processed
+  because the target indicated by the lun field does not exist.
+
+  VIRTIO_SCSI_S_RESET if the request was cancelled due to a bus
+  or device reset (including a task management function).
+
+  VIRTIO_SCSI_S_TRANSPORT_FAILURE if the request failed due to a
+  problem in the connection between the host and the target
+  (severed link).
+
+  VIRTIO_SCSI_S_TARGET_FAILURE if the target is suffering a
+  failure and the guest should not retry on other paths.
+
+  VIRTIO_SCSI_S_NEXUS_FAILURE if the nexus is suffering a failure

+
+  VIRTIO_SCSI_S_BUSY if the request failed but retrying on the

+
+  The type is VIRTIO_SCSI_T_TMF; the subtype field defines. All

+  field must always be specified and identifies the requested
+  task management function.
+
+  Other fields may be irrelevant for the requested TMF; if so,
+  they are ignored but they should still be present. The lun
+  field is in the same format specified for request queues; the
+  single level LUN is ignored when the task management function
+  addresses a whole I_T nexus. When relevant, the value of the id
+  field is matched against the id values passed on the requestq.
+
+  The outcome of the task management function is written by the

+
+  By sending this command, the driver asks the device which
+  events the given LUN can report, as described in paragraphs 6.6
+  and A.6 of the SCSI MMC specification. The driver writes the
+  events it is interested in into the event_requested; the device
+  responds by writing the events that it supports into
+  event_actual.
+
+  The type is VIRTIO_SCSI_T_AN_QUERY. The lun and event_requested
+  fields are written by the driver. The event_actual and response
+  fields are written by the device.
+
+  No command-specific values are defined for the response byte.
+
+  Asynchronous notification subscription
+#define VIRTIO_SCSI_T_AN_SUBSCRIBE                2
+
+
+
+struct virtio_scsi_ctrl_an {
+
+    // Read-only part
+
+    u32 type;
+
+    u8  lun[8];
+
+    u32 event_requested;
+
+    // Write-only part
+
+    u32 event_actual;
+
+    u8  response;
+
+}
+
+  By sending this command, the driver asks the specified LUN to
+  report events for its physical interface, again as described in
+  the SCSI MMC specification. The driver writes the events it is
+  interested in into the event_requested; the device responds by
+  writing the events that it supports into event_actual.
+
+  Event types are the same as for the asynchronous notification
+  query message.
+
+  The type is VIRTIO_SCSI_T_AN_SUBSCRIBE. The lun and
+  event_requested fields are written by the driver. The
+  event_actual and response fields are written by the device.
+
+  No command-specific values are defined for the response byte.
+
+  Device Operation: eventq
+
+The eventq is used by the device to report information on logical
+units that are attached to it. The driver should always leave a
+few buffers ready in the eventq. In general, the device will not
+queue events to cope with an empty eventq, and will end up
+dropping events if it finds no buffer ready. However, when
+reporting events for many LUNs (e.g. when a whole target
+disappears), the device can throttle events to avoid dropping
+them. For this reason, placing 10-15 buffers on the event queue
+should be enough.
+
+Buffers are placed in the eventq and filled by the device when
+interesting events occur. The buffers should be strictly
+write-only (device-filled) and the size of the buffers should be
+at least the value given in the device's configuration
+information.
+
+Buffers returned by the device on the eventq will be referred to
+as "events" in the rest of this section. Events have the
+following format:
+
+#define VIRTIO_SCSI_T_EVENTS_MISSED   0x80000000
+
+
+
+struct virtio_scsi_event {
+
+    // Write-only part
+
+    u32 event;
+
+    ...
+
+}
+
+If bit 31 is set in the event field, the device failed to report
+an event due to missing buffers. In this case, the driver should
+poll the logical units for unit attention conditions, and/or do
+whatever form of bus scan is appropriate for the guest operating
+system.
+
+Other data that the device writes to the buffer depends on the
+contents of the event field. The following events are defined:
+
+  No event
+#define VIRTIO_SCSI_T_NO_EVENT         0
+
+  This event is fired in the following cases:
+
+  When the device detects in the eventq a buffer that is shorter
+    than what is indicated in the configuration field, it might
+    use it immediately and put this dummy value in the event
+    field. A well-written driver will never observe this
+    situation.
+
+  When events are dropped, the device may signal this event as
+    soon as the drivers makes a buffer available, in order to
+    request action from the driver. In this case, of course, this
+    event will be reported with the VIRTIO_SCSI_T_EVENTS_MISSED
+    flag.
+
+  Transport reset
+#define VIRTIO_SCSI_T_TRANSPORT_RESET  1
+
+
+
+struct virtio_scsi_event_reset {
+
+    // Write-only part
+
+    u32 event;
+
+    u8  lun[8];
+
+    u32 reason;
+
+}
+
+
+
+#define VIRTIO_SCSI_EVT_RESET_HARD         0
+
+#define VIRTIO_SCSI_EVT_RESET_RESCAN       1
+
+#define VIRTIO_SCSI_EVT_RESET_REMOVED      2
+
+  By sending this event, the device signals that a logical unit
+  on a target has been reset, including the case of a new device
+  appearing or disappearing on the bus.The device fills in all
+  fields. The event field is set to
+  VIRTIO_SCSI_T_TRANSPORT_RESET. The lun field addresses a
+  logical unit in the SCSI host.
+
+  The reason value is one of the three #define values appearing
+  above:
+
+  VIRTIO_SCSI_EVT_RESET_REMOVED (“LUN/target removed”) is used if
+    the target or logical unit is no longer able to receive
+    commands.
+
+  VIRTIO_SCSI_EVT_RESET_HARD (“LUN hard reset”) is used if the
+    logical unit has been reset, but is still present.
+
+  VIRTIO_SCSI_EVT_RESET_RESCAN (“rescan LUN/target”) is used if a
+    target or logical unit has just appeared on the device.
+
+  The “removed” and “rescan” events, when sent for LUN 0, may
+  apply to the entire target. After receiving them the driver
+  should ask the initiator to rescan the target, in order to
+  detect the case when an entire target has appeared or
+  disappeared. These two events will never be reported unless the
+  VIRTIO_SCSI_F_HOTPLUG feature was negotiated between the host
+  and the guest.
+
+  Events will also be reported via sense codes (this obviously
+  does not apply to newly appeared buses or targets, since the
+  application has never discovered them):
+
+  “LUN/target removed” maps to sense key ILLEGAL REQUEST, asc
+    0x25, ascq 0x00 (LOGICAL UNIT NOT SUPPORTED)
+
+  “LUN hard reset” maps to sense key UNIT ATTENTION, asc 0x29
+    (POWER ON, RESET OR BUS DEVICE RESET OCCURRED)
+
+  “rescan LUN/target” maps to sense key UNIT ATTENTION, asc 0x3f,
+    ascq 0x0e (REPORTED LUNS DATA HAS CHANGED)
+
+  The preferred way to detect transport reset is always to use
+  events, because sense codes are only seen by the driver when it
+  sends a SCSI command to the logical unit or target. However, in
+  case events are dropped, the initiator will still be able to
+  synchronize with the actual state of the controller if the
+  driver asks the initiator to rescan of the SCSI bus. During the
+  rescan, the initiator will be able to observe the above sense
+  codes, and it will process them as if it the driver had
+  received the equivalent event.
+
+  Asynchronous notification
+#define VIRTIO_SCSI_T_ASYNC_NOTIFY     2
+
+
+
+struct virtio_scsi_event_an {
+
+    // Write-only part
+
+    u32 event;
+
+    u8  lun[8];
+
+    u32 reason;
+
+}
+
+  By sending this event, the device signals that an asynchronous
+  event was fired from a physical interface.
+
+  All fields are written by the device. The event field is set to
+  VIRTIO_SCSI_T_ASYNC_NOTIFY. The lun field addresses a logical
+  unit in the SCSI host. The reason field is a subset of the
+  events that the driver has subscribed to via the "Asynchronous
+  notification subscription" command.
+
+  When dropped events are reported, the driver should poll for
+  asynchronous events manually using SCSI commands.
+
+Appendix X: virtio-mmio
+
+Virtual environments without PCI support (a common situation in
+embedded devices models) might use simple memory mapped device (“
+virtio-mmio”) instead of the PCI device.
+
+The memory mapped virtio device behaviour is based on the PCI
+device specification. Therefore most of operations like device
+initialization, queues configuration and buffer transfers are
+nearly identical. Existing differences are described in the
+following sections.
+
+  Device Initialization
+
+Instead of using the PCI IO space for virtio header, the “
+virtio-mmio” device provides a set of memory mapped control
+registers, all 32 bits wide, followed by device-specific
+configuration space. The following list presents their layout:
+
+  Offset from the device base address | Direction | Name
+ Description
+
+  0x000 | R | MagicValue
+ “virt” string.
+
+  0x004 | R | Version
+ Device version number. Currently must be 1.
+
+  0x008 | R | DeviceID
+ Virtio Subsystem Device ID (ie. 1 for network card).
+
+  0x00c | R | VendorID
+ Virtio Subsystem Vendor ID.
+
+  0x010 | R | HostFeatures
+ Flags representing features the device supports.
+ Reading from this register returns 32 consecutive flag bits,
+  first bit depending on the last value written to
+  HostFeaturesSel register. Access to this register returns bits HostFeaturesSel*32
+
+   to (HostFeaturesSel*32)+31
+, eg. feature bits 0 to 31 if
+  HostFeaturesSel is set to 0 and features bits 32 to 63 if
+  HostFeaturesSel is set to 1. Also see [sub:Feature-Bits]
+
+  0x014 | W | HostFeaturesSel
+ Device (Host) features word selection.
+ Writing to this register selects a set of 32 device feature bits
+  accessible by reading from HostFeatures register. Device driver
+  must write a value to the HostFeaturesSel register before
+  reading from the HostFeatures register.
+
+  0x020 | W | GuestFeatures
+ Flags representing device features understood and activated by
+  the driver.
+ Writing to this register sets 32 consecutive flag bits, first
+  bit depending on the last value written to GuestFeaturesSel
+  register. Access to this register sets bits GuestFeaturesSel*32
+
+   to (GuestFeaturesSel*32)+31
+, eg. feature bits 0 to 31 if
+  GuestFeaturesSel is set to 0 and features bits 32 to 63 if
+  GuestFeaturesSel is set to 1. Also see [sub:Feature-Bits]
+
+  0x024 | W | GuestFeaturesSel
+ Activated (Guest) features word selection.
+ Writing to this register selects a set of 32 activated feature
+  bits accessible by writing to the GuestFeatures register.
+  Device driver must write a value to the GuestFeaturesSel
+  register before writing to the GuestFeatures register.
+
+  0x028 | W | GuestPageSize
+ Guest page size.
+ Device driver must write the guest page size in bytes to the
+  register during initialization, before any queues are used.
+  This value must be a power of 2 and is used by the Host to
+  calculate Guest address of the first queue page (see QueuePFN).
+
+  0x030 | W | QueueSel
+ Virtual queue index (first queue is 0).
+ Writing to this register selects the virtual queue that the
+  following operations on QueueNum, QueueAlign and QueuePFN apply
+  to.
+
+  0x034 | R | QueueNumMax
+ Maximum virtual queue size.
+ Reading from the register returns the maximum size of the queue
+  the Host is ready to process or zero (0x0) if the queue is not
+  available. This applies to the queue selected by writing to
+  QueueSel and is allowed only when QueuePFN is set to zero
+  (0x0), so when the queue is not actively used.
+
+  0x038 | W | QueueNum
+ Virtual queue size.
+ Queue size is a number of elements in the queue, therefore size
+  of the descriptor table and both available and used rings.
+ Writing to this register notifies the Host what size of the
+  queue the Guest will use. This applies to the queue selected by
+  writing to QueueSel.
+
+  0x03c | W | QueueAlign
+ Used Ring alignment in the virtual queue.
+ Writing to this register notifies the Host about alignment
+  boundary of the Used Ring in bytes. This value must be a power
+  of 2 and applies to the queue selected by writing to QueueSel.
+
+  0x040 | RW | QueuePFN
+ Guest physical page number of the virtual queue.
+ Writing to this register notifies the host about location of the
+  virtual queue in the Guest's physical address space. This value
+  is the index number of a page starting with the queue
+  Descriptor Table. Value zero (0x0) means physical address zero
+  (0x00000000) and is illegal. When the Guest stops using the
+  queue it must write zero (0x0) to this register.
+ Reading from this register returns the currently used page
+  number of the queue, therefore a value other than zero (0x0)
+  means that the queue is in use.
+ Both read and write accesses apply to the queue selected by
+  writing to QueueSel.
+
+  0x050 | W | QueueNotify
+ Queue notifier.
+ Writing a queue index to this register notifies the Host that
+  there are new buffers to process in the queue.
+
+  0x60 | R | InterruptStatus
+Interrupt status.
+Reading from this register returns a bit mask of interrupts
+  asserted by the device. An interrupt is asserted if the
+  corresponding bit is set, ie. equals one (1).
+
+  Bit 0 | Used Ring Update
+This interrupt is asserted when the Host has updated the Used
+    Ring in at least one of the active virtual queues.
+
+  Bit 1 | Configuration change
+This interrupt is asserted when configuration of the device has
+    changed.
+
+  0x064 | W | InterruptACK
+ Interrupt acknowledge.
+ Writing to this register notifies the Host that the Guest
+  finished handling interrupts. Set bits in the value clear the
+  corresponding bits of the InterruptStatus register.
+
+  0x070 | RW | Status
+ Device status.
+ Reading from this register returns the current device status
+  flags.
+ Writing non-zero values to this register sets the status flags,
+  indicating the Guest progress. Writing zero (0x0) to this
+  register triggers a device reset.
+ Also see [sub:Device-Initialization-Sequence]
+
+  0x100+ | RW | Config
+ Device-specific configuration space starts at an offset 0x100
+  and is accessed with byte alignment. Its meaning and size
+  depends on the device and the driver.
+
+Virtual queue size is a number of elements in the queue,
+therefore size of the descriptor table and both available and
+used rings.
+
+The endianness of the registers follows the native endianness of
+the Guest. Writing to registers described as “R” and reading from
+registers described as “W” is not permitted and can cause
+undefined behavior.
+
+The device initialization is performed as described in [sub:Device-Initialization-Sequence]
+ with one exception: the Guest must notify the Host about its
+page size, writing the size in bytes to GuestPageSize register
+before the initialization is finished.
+
+The memory mapped virtio devices generate single interrupt only,
+therefore no special configuration is required.
+
+  Virtqueue Configuration
+
+The virtual queue configuration is performed in a similar way to
+the one described in [sec:Virtqueue-Configuration] with a few
+additional operations:
+
+  Select the queue writing its index (first queue is 0) to the
+  QueueSel register.
+
+  Check if the queue is not already in use: read QueuePFN
+  register, returned value should be zero (0x0).
+
+  Read maximum queue size (number of elements) from the
+  QueueNumMax register. If the returned value is zero (0x0) the
+  queue is not available.
+
+  Allocate and zero the queue pages in contiguous virtual memory,
+  aligning the Used Ring to an optimal boundary (usually page
+  size). Size of the allocated queue may be smaller than or equal
+  to the maximum size returned by the Host.
+
+  Notify the Host about the queue size by writing the size to
+  QueueNum register.
+
+  Notify the Host about the used alignment by writing its value
+  in bytes to QueueAlign register.
+
+  Write the physical number of the first page of the queue to the
+  QueuePFN register.
+
+The queue and the device are ready to begin normal operations
+now.
+
+  Device Operation
+
+The memory mapped virtio device behaves in the same way as
+described in [sec:Device-Operation], with the following
+exceptions:
+
+  The device is notified about new buffers available in a queue
+  by writing the queue index to register QueueNum instead of the
+  virtio header in PCI I/O space ([sub:Notifying-The-Device]).
+
+  The memory mapped virtio device is using single, dedicated
+  interrupt signal, which is raised when at least one of the
+  interrupts described in the InterruptStatus register
+  description is asserted. After receiving an interrupt, the
+  driver must read the InterruptStatus register to check what
+  caused the interrupt (see the register description). After the
+  interrupt is handled, the driver must acknowledge it by writing
+  a bit mask corresponding to the serviced interrupt to the
+  InterruptACK register.

- * IXDP2x00-common PCI init
- *
- * The IXDP2[48]00 has a horrid PCI bus layout. Basically the board 
- * contains two NPUs (ingress and egress) connected over PCI,  both running 
- * instances  of the kernel. So far so good. Peers on the PCI bus running 
- * Linux is a common design in telecom systems. The problem is that instead 
- * of all the devices being controlled by a single host, different
- * devices are controlled by different NPUs on the same bus, leading to
- * multiple hosts on the bus. The exact bus layout looks like:
- *
- *                   Bus 0
- *    Master NPU <-------------------+-------------------> Slave NPU
- *                                   |
- *                                   |
- *                                  P2P 
- *                                   |
- *
- *                  Bus 1            |
- *               <--+------+---------+---------+------+-->
- *                  |      |         |         |      |
- *                  |      |         |         |      |
- *             ... Dev    PMC       Media     Eth0   Eth1 ...
- *
- * The master controls all but Eth1, which is controlled by the
- * slave. What this means is that the both the master and the slave
- * have to scan the bus, but only one of them can enumerate the bus.
- * In addition, after the bus is scanned, each kernel must remove
- * the device(s) it does not control from the PCI dev list otherwise
- * a driver on each NPU will try to manage it and we will have horrible
- * conflicts. Oh..and the slave NPU needs to see the master NPU
- * for Intel's drivers to work properly. Closed source drivers...
- *
- * The way we deal with this is fairly simple but ugly:
- *
- * 1) Let master scan and enumerate the bus completely.
- * 2) Master deletes Eth1 from device list.
- * 3) Slave scans bus and then deletes all but Eth1 (Eth0 on slave)
- *    from device list.
- * 4) Find HW designers and LART them.
- *
- * The boards also do not do normal PCI IRQ routing, or any sort of 
- * sensical  swizzling, so we just need to check where on the  bus a
- * device sits and figure out to which CPLD pin the interrupt is routed.
- * See ixdp2[48]00.c files.

+ * post-setup state of ENABLED is appropriate for kernels with PM
+ * runtime disabled.  The DISABLED state is appropriate for unusual IP
+ * blocks such as the MPU WDTIMER on kernels without WDTIMER drivers
+ * included, since the WDTIMER starts running on reset and will reset
+ * the MPU if left active.
+ *
+ * This post-setup mechanism is deprecated.  Once all of the OMAP
+ * drivers have been converted to use PM runtime, and all of the IP
+ * block data and interconnect data is available to the hwmod code, it
+ * should be possible to replace this mechanism with a "lazy reset"
+ * arrangement.  In a "lazy reset" setup, each IP block is enabled
+ * when the driver first probes, then all remaining IP blocks without
+ * drivers are either shut down or enabled after the drivers have
+ * loaded.  However, this cannot take place until the above
+ * preconditions have been met, since otherwise the late reset code

-	 * - PRCM asserts idle_req to the USBHOST module ( This typically
-	 *   happens when the system is going to a low power mode : all ports
-	 *   have been suspended, the master part of the USBHOST module has
-	 *   entered the standby state, and SW has cut the functional clocks)
-	 * - an USBHOST interrupt occurs before the module is able to answer
-	 *   idle_ack, typically a remote wakeup IRQ.
-	 * Then the USB HOST module will enter a deadlock situation where it
-	 * is no more accessible nor functional.

-	 * Normally, with the shift-and-add approach, if both numbers are

-	 *
-	 *		  x		    32
-	 *	( 2  -  ------ ) mod 2  *  2
-	 *		   32
-	 *		  2
-	 *
-	 * (the `mod 2' subtracts 1 from 1.bbbb).  To avoid lots of 2^32s,
-	 * we can treat this as if the radix point were just to the left
-	 * of the sign bit (multiply by 2^32), and get
-	 *
-	 *	-x  =  (2 - x) mod 2
-	 *
-	 * Then, ignoring the `mod 2's for convenience:
-	 *
-	 *   x *  y	= xy
-	 *  -x *  y	= 2y - xy
-	 *   x * -y	= 2x - xy
-	 *  -x * -y	= 4 - 2x - 2y + xy
-	 *
-	 * For signed multiplies, we subtract (x << 32) from the partial
-	 * product to fix this problem for negative multipliers (see mul.s).
-	 * Because of the way the shift into the partial product is calculated
-	 * (N xor V), this term is automatically removed for the multiplicand,
-	 * so we don't have to adjust.
-	 *
-	 * But for unsigned multiplies, the high order bit wasn't a sign bit,
-	 * and the correction is wrong.  So for unsigned multiplies where the
-	 * high order bit is one, we end up with xy - (y << 32).  To fix it

- * Modifying code must take extra care. On an SMP machine, if

- * that CPU will have undefined results and possibly take a GPF.
- * We use kstop_machine to stop other CPUS from exectuing code.
- * But this does not stop NMIs from happening. We still need
- * to protect against that. We separate out the modification of
- * the code to take care of this.
- *
- * Two buffers are added: An IP buffer and a "code" buffer.
- *
- * 1) Put the instruction pointer into the IP buffer
- *    and the new code into the "code" buffer.
- * 2) Wait for any running NMIs to finish and set a flag that says
- *    we are modifying code, it is done in an atomic operation.
- * 3) Write the code
- * 4) clear the flag.
- * 5) Wait for any running NMIs to finish.
- *
- * If an NMI is executed, the first thing it does is to call
- * "ftrace_nmi_enter". This will check if the flag is set to write
- * and if it is, it will write what is in the IP and "code" buffers.
- *
- * The trick is, it does not matter if everyone is writing the same
- * content to the code location. Also, if a CPU is executing code
- * it is OK to write to that code location if the contents being written

-    This driver supports the bmp085 digital barometric pressure
-    and temperature sensor from Bosch Sensortec. The datasheet
-    is available from their website:
-    http://www.bosch-sensortec.com/content/language1/downloads/BST-BMP085-DS000-05.pdf
-
-    A pressure measurement is issued by reading from pressure0_input.
-    The return value ranges from 30000 to 110000 pascal with a resulution
-    of 1 pascal (0.01 millibar) which enables measurements from 9000m above
-    to 500m below sea level.
-
-    The temperature can be read from temp0_input. Values range from
-    -400 to 850 representing the ambient temperature in degree celsius
-    multiplied by 10.The resolution is 0.1 celsius.
-
-    Because ambient pressure is temperature dependent, a temperature
-    measurement will be executed automatically even if the user is reading
-    from pressure0_input. This happens if the last temperature measurement
-    has been executed more then one second ago.
-
-    To decrease RMS noise from pressure measurements, the bmp085 can
-    autonomously calculate the average of up to eight samples. This is
-    set up by writing to the oversampling sysfs file. Accepted values
-    are 0, 1, 2 and 3. 2^x when x is the value written to this file
-    specifies the number of samples used to calculate the ambient pressure.
-    RMS noise is specified with six pascal (without averaging) and decreases
-    down to 3 pascal when using an oversampling setting of 3.

+	  The Configurable Composite Gadget supports multiple USB
+	  functions: acm, mass storage, rndis and FunctionFS.
+	  Each function can be configured and enabled/disabled
+	  dynamically from userspace through a sysfs interface.
+
+	  In order to compile this (either as a module or built-in),
+	  "USB Gadget Drivers" and anything under it must not be
+	  selected compiled-in in
+	  Device Drivers->USB Support->USB Gadget Support.
+	  However, you can say "M" there, if you do, the
+	  Configurable Composite Gadget can be compiled "M" only
+	  or not at all.

+				TODO
+				====
+Introduction
+============
+
+These drivers add support for IndustryPack devices: carrier and mezzanine
+boards.
+
+The ipack driver is just an abstraction of the bus providing the common
+operations between the two kind of boards.
+
+TODO
+====
+
+TPCI-200
+--------
+
+* It receives the name of the mezzanine plugged in each slot by SYSFS.
+  No autodetection supported yet, because the mezzanine driver could not be
+  loaded at the time that the tpci200 driver loads.
+
+* It has a linked list with the tpci200 devices it is managing. Get rid of it
+  and use driver_for_each_device() instead.
+
+IP-OCTAL
+--------
+
+* It has a linked list which saves the devices it is currently
+  managing. It should use the driver_for_each_device() function. It is not there
+  due to the impossibility of using container_of macro to recover the
+  corresponding "struct ipoctal" because the attribute "struct ipack_device" is
+  a pointer. This code should be refactored.
+
+Ipack
+-----
+
+* The structures and API exported can be improved a lot. For example, the
+  way to unregistering mezzanine devices, doing the mezzanine driver a call to
+  remove_device() to notify the carrier driver, or the opposite with the call to
+  the ipack_driver_ops' remove() function could be improved.

- * linux/byteorder_generic.h
- * Generic Byte-reordering support
- *
- * Francois-Rene Rideau <fare@tunes.org> 19970707
- *    gathered all the good ideas from all asm-foo/byteorder.h into one file,
- *    cleaned them up.
- *    I hope it is compliant with non-GCC compilers.
- *    I decided to put __BYTEORDER_HAS_U64__ in byteorder.h,
- *    because I wasn't sure it would be ok to put it in types.h
- *    Upgraded it to 2.1.43
- * Francois-Rene Rideau <fare@tunes.org> 19971012
- *    Upgraded it to 2.1.57
- *    to please Linus T., replaced huge #ifdef's between little/big endian
- *    by nestedly #include'd files.
- * Francois-Rene Rideau <fare@tunes.org> 19971205
- *    Made it to 2.1.71; now a facelift:
- *    Put files under include/linux/byteorder/
- *    Split swab from generic support.
- *
- * TODO:
- *   = Regular kernel maintainers could also replace all these manual
- *    byteswap macros that remain, disseminated among drivers,
- *    after some grep or the sources...
- *   = Linus might want to rename all these macros and files to fit his taste,
- *    to fit his personal naming scheme.
- *   = it seems that a few drivers would also appreciate
- *    nybble swapping support...
- *   = every architecture could add their byteswap macro in asm/byteorder.h
- *    see how some architectures already do (i386, alpha, ppc, etc)
- *   = cpu_to_beXX and beXX_to_cpu might some day need to be well
- *    distinguished throughout the kernel. This is not the case currently,
- *    since little endian, big endian, and pdp endian machines needn't it.
- *    But this might be the case for, say, a port of Linux to 20/21 bit
- *    architectures (and F21 Linux addict around?).
- */
-
-/*
- * The following macros are to be defined by <asm/byteorder.h>:
- *
- * Conversion of long and short int between network and host format
- *	ntohl(__u32 x)
- *	ntohs(__u16 x)
- *	htonl(__u32 x)
- *	htons(__u16 x)
- * It seems that some programs (which? where? or perhaps a standard? POSIX?)
- * might like the above to be functions, not macros (why?).
- * if that's true, then detect them, and take measures.
- * Anyway, the measure is: define only ___ntohl as a macro instead,
- * and in a separate file, have
- * unsigned long inline ntohl(x){return ___ntohl(x);}
- *
- * The same for constant arguments
- *	__constant_ntohl(__u32 x)
- *	__constant_ntohs(__u16 x)
- *	__constant_htonl(__u32 x)
- *	__constant_htons(__u16 x)
- *
- * Conversion of XX-bit integers (16- 32- or 64-)
- * between native CPU format and little/big endian format
- * 64-bit stuff only defined for proper architectures
- *	cpu_to_[bl]eXX(__uXX x)
- *	[bl]eXX_to_cpu(__uXX x)
- *
- * The same, but takes a pointer to the value to convert
- *	cpu_to_[bl]eXXp(__uXX x)
- *	[bl]eXX_to_cpup(__uXX x)
- *
- * The same, but change in situ
- *	cpu_to_[bl]eXXs(__uXX x)
- *	[bl]eXX_to_cpus(__uXX x)
- *
- * See asm-foo/byteorder.h for examples of how to provide
- * architecture-optimized versions

- * The original code was written for the MBX860 board.  I tried to make

- * To save porting time, I did not bother to change any object names

- * It still needs lots of work........When it was easy, I included code
- * to support the SCCs, but this has never been tested, nor is it complete.
- * Only the SCCs support modem control, so that is not complete either.

-	  to talk directly to the device. These files are "virtual", meaning
-	  they are generated on the fly and not stored on the hard drive.

-
-	  These additional devices are difficult to handle in userspace, if
-	  information about USB interfaces must be available. One device

- * Description: MIPS USB IP core family device controller
- *              Currently it only supports IP part number CI13412
- *
- * This driver is composed of several blocks:
- * - HW:     hardware interface
- * - DBG:    debug facilities (optional)
- * - UTIL:   utilities
- * - ISR:    interrupts handling
- * - ENDPT:  endpoint operations (Gadget API)
- * - GADGET: gadget operations (Gadget API)
- * - BUS:    bus glue code, bus abstraction layer
- *
- * Compile Options
- * - CONFIG_USB_GADGET_DEBUG_FILES: enable debug facilities
- * - STALL_IN:  non-empty bulk-in pipes cannot be halted
- *              if defined mass storage compliance succeeds but with warnings
- *              => case 4: Hi >  Dn
- *              => case 5: Hi >  Di
- *              => case 8: Hi <> Do
- *              if undefined usbtest 13 fails
- * - TRACE:     enable function tracing (depends on DEBUG)
- *
- * Main Features
- * - Chapter 9 & Mass Storage Compliance with Gadget File Storage
- * - Chapter 9 Compliance with Gadget Zero (STALL_IN undefined)
- * - Normal & LPM support
- *
- * USBTEST Report
- * - OK: 0-12, 13 (STALL_IN defined) & 14
- * - Not Supported: 15 & 16 (ISO)
- *
- * TODO List
- * - OTG
- * - Isochronous & Interrupt Traffic
- * - Handle requests which spawns into several TDs
- * - GET_STATUS(device) - always reports 0
- * - Gadget API (majority of optional features)
- * - Suspend & Remote Wakeup

+ * causing the master nodeid to briefly change during the aborted recovery, and
+ * change back to the original value in the second recovery.  The MSTCPY locks
+ * may or may not have been purged during the aborted recovery.  Another node
+ * with an outstanding request in waiters list and a request reply saved in the
+ * requestqueue, cannot know whether it should ignore the reply and resend the

-	  This option enables UBIFS debugging support. It makes sure various

-	  in (this all is compiled out otherwise). Assertions are light-weight
-	  and this option also enables them. Self-checks, debugging messages and

-	  recommended to have debugging support enabled, and it should not slow
-	  down UBIFS. You can then further enable / disable individual  debugging
-	  features using UBIFS module parameters and the corresponding sysfs
-	  interfaces.

+ * The printk log buffer consists of a chain of concatenated variable
+ * length records. Every record starts with a record header, containing
+ * the overall length of the record.
+ *
+ * The heads to the first and last entry in the buffer, as well as the
+ * sequence numbers of these both entries are maintained when messages
+ * are stored..
+ *
+ * If the heads indicate available messages, the length in the header
+ * tells the start next message. A length == 0 for the next message
+ * indicates a wrap-around to the beginning of the buffer.
+ *
+ * Every record carries the monotonic timestamp in microseconds, as well as
+ * the standard userspace syslog level and syslog facility. The usual
+ * kernel messages use LOG_KERN; userspace-injected messages always carry
+ * a matching syslog facility, by default LOG_USER. The origin of every
+ * message can be reliably determined that way.
+ *
+ * The human readable log message directly follows the message header. The
+ * length of the message text is stored in the header, the stored message
+ * is not terminated.
+ *
+ * Optionally, a message can carry a dictionary of properties (key/value pairs),
+ * to provide userspace with a machine-readable message context.
+ *
+ * Examples for well-defined, commonly used property names are:
+ *   DEVICE=b12:8               device identifier
+ *                                b12:8         block dev_t
+ *                                c127:3        char dev_t
+ *                                n8            netdev ifindex
+ *                                +sound:card0  subsystem:devname
+ *   SUBSYSTEM=pci              driver-core subsystem name
+ *
+ * Valid characters in property names are [a-zA-Z0-9.-_]. The plain text value
+ * follows directly after a '=' character. Every property is terminated by
+ * a '\0' character. The last property is not terminated.
+ *
+ * Example of a message structure:
+ *   0000  ff 8f 00 00 00 00 00 00      monotonic time in nsec
+ *   0008  34 00                        record is 52 bytes long
+ *   000a        0b 00                  text is 11 bytes long
+ *   000c              1f 00            dictionary is 23 bytes long
+ *   000e                    03 00      LOG_KERN (facility) LOG_ERR (level)
+ *   0010  69 74 27 73 20 61 20 6c      "it's a l"
+ *         69 6e 65                     "ine"

+ *
+ * The 'struct log' buffer header must never be directly exported to
+ * userspace, it is a kernel-private implementation detail that might
+ * need to be changed in the future, when the requirements change.
+ *
+ * /dev/kmsg exports the structured data in the following line format:

-	 *	Otherwise, a task taking the early exit can race

-	 *	taking the early exit from freeing a data structure that
-	 *	is still being referenced (out of order) by the task
-	 *	doing the srcu_read_unlock().
-	 *

-	help
-	  This option provides support for retaining authentication tokens and

-
-	  It also includes provision of methods by which such keys might be
-	  associated with a process so that network filesystems, encryption
-	  support and the like can find them.
-
-	  Furthermore, a special type of key is available that acts as keyring:
-	  a searchable sequence of keys. Each process is equipped with access
-	  to five standard keyrings: UID-specific, GID-specific, session,
-	  process and thread.

-	  generated and RSA-sealed by the TPM. The TPM only unseals the keys,
-	  if the boot PCRs and other criteria match.  Userspace will only ever
-	  see encrypted blobs.

-	help
-	  This option provides support for create/encrypting/decrypting keys
-	  in the kernel.  Encrypted keys are kernel generated random numbers,
-	  which are encrypted/decrypted with a 'master' symmetric key. The
-	  'master' key can be either a trusted-key or user-key type.
-	  Userspace only ever sees/stores encrypted blobs.
-

-	  reading process.
-
-	  The only keys included in the list are those that grant View
-	  permission to the reading process whether or not it possesses them.
-	  Note that LSM security checks are still performed, and may further
-	  filter out keys that the current process is not authorised to view.
-
-	  Only key attributes are listed here; key payloads are not included in
-	  the resulting table.

+	  This option provides support for retaining authentication tokens and
+	  access keys in the kernel.
+
+	  It also includes provision of methods by which such keys might be
+	  associated with a process so that network filesystems, encryption
+	  support and the like can find them.
+
+	  Furthermore, a special type of key is available that acts as keyring:
+	  a searchable sequence of keys. Each process is equipped with access
+	  to five standard keyrings: UID-specific, GID-specific, session,
+	  process and thread.
+
+	  If you are unsure as to whether this is required, answer N.

+	help
+	  This option provides support for creating, sealing, and unsealing
+	  keys in the kernel. Trusted keys are random number symmetric keys,
+	  generated and RSA-sealed by the TPM. The TPM only unseals the keys,
+	  if the boot PCRs and other criteria match.  Userspace will only ever
+	  see encrypted blobs.
+
+	  If you are unsure as to whether this is required, answer N.

+	help
+	  This option provides support for create/encrypting/decrypting keys
+	  in the kernel.  Encrypted keys are kernel generated random numbers,
+	  which are encrypted/decrypted with a 'master' symmetric key. The
+	  'master' key can be either a trusted-key or user-key type.
+	  Userspace only ever sees/stores encrypted blobs.
+
+	  If you are unsure as to whether this is required, answer N.
+
+config KEYS_DEBUG_PROC_KEYS
+	bool "Enable the /proc/keys file by which keys may be viewed"

+	help
+	  This option turns on support for the /proc/keys file - through which
+	  can be listed all the keys on the system that are viewable by the
+	  reading process.
+
+	  The only keys included in the list are those that grant View
+	  permission to the reading process whether or not it possesses them.
+	  Note that LSM security checks are still performed, and may further
+	  filter out keys that the current process is not authorised to view.
+
+	  Only key attributes are listed here; key payloads are not included in
+	  the resulting table.
+
+	  If you are unsure as to whether this is required, answer N.

+ * XBAR: The core cross-bar component of the AHUB.
+ * CIF:  Client Interface; the HW module connecting an audio device to the
+ *       XBAR.
+ * DAM:  Digital Audio Mixer: A HW module that mixes multiple audio streams,
+ *       possibly including sample-rate conversion.
+ *
+ * Each TX CIF transmits data into the XBAR. Each RX CIF can receive audio
+ * transmitted by a particular TX CIF.
+ *
+ * This driver is currently very simplistic; many HW features are not
+ * exposed; DAMs are not supported, only 16-bit stereo audio is supported,
+ * etc.

+# This file has some examples for creating a MIN_CONFIG.

+#
+# A MIN_CONFIG is very useful as it is the minimum configuration
+# needed to boot a given machine. You can debug someone else's
+# .config by only setting the configs in your MIN_CONFIG. The closer
+# your MIN_CONFIG is to the true minimum set of configs needed to
+# boot your machine, the closer the config you test with will be
+# to the users config that had the failure.
+#
+# The make_min_config test allows you to create a MIN_CONFIG that
+# is truly the minimum set of configs needed to boot a box.
+#
+# In this example, the final config will reside in
+# ${CONFIG_DIR}/config-new-min and ${CONFIG_DIR}/config-new-min-net.
+# Just move one to the location you have set for MIN_CONFIG.
+#
+# The first test creates a MIN_CONFIG that will be the minimum

+# The second test creates a MIN_CONFIG that will only boot
+# the target and most likely will not let you ssh to it. (Notice
+# how the second test uses the first test's result to continue with.
+# This is because the second test config is a subset of the first).
+#
+# The ${CONFIG_DIR}/config-skip (and -net) will hold the configs
+# that ktest.pl found would not boot the target without them set.
+# The config-new-min holds configs that ktest.pl could not test
+# directly because another config that was needed to boot the box
+# selected them. Sometimes it is possible that this file will hold
+# the true minimum configuration. You can test to see if this is
+# the case by running the boot test with BOOT_TYPE = allnoconfig and
+# setting setting the MIN_CONFIG to ${CONFIG_DIR}/config-skip. If the
+# machine still boots, then you can use the config-skip as your MIN_CONFIG.
