+Description:
+		This directory exposes interfaces for interacting with
+		the FSP and platform dumps through OPAL firmware interface.
+
+		This is only for the powerpc/powernv platform.
+
+		initiate_dump:	When '1' is written to it,
+				we will initiate a dump.
+				Read this file for supported commands.
+
+		0xXX-0xYYYY:	A directory for dump of type 0xXX and
+				id 0xYYYY (in hex). The name of this
+				directory should not be relied upon to
+				be in this format, only that it's unique
+				among all dumps. For determining the type
+				and ID of the dump, use the id and type files.
+				Do not rely on any particular size of dump
+				type or dump id.
+
+		Each dump has the following files:
+		id:		An ASCII representation of the dump ID
+				in hex (e.g. '0x01')
+		type:		An ASCII representation of the type of
+				dump in the format "0x%x %s" with the ID
+				in hex and a description of the dump type
+				(or 'unknown').
+				Type '0xffffffff unknown' is used when
+				we could not get the type from firmware.
+				e.g. '0x02 System/Platform Dump'
+		dump:		A binary file containing the dump.
+				The size of the dump is the size of this file.
+		acknowledge:	When 'ack' is written to this, we will
+				acknowledge that we've retrieved the
+				dump to the service processor. It will
+				then remove it, making the dump
+				inaccessible.
+				Reading this file will get a list of
+				supported actions.

+What:		/sys/firmware/opal/elog
+Date:		Feb 2014
+Contact:	Stewart Smith <stewart@linux.vnet.ibm.com>
+Description:
+		This directory exposes error log entries retrieved
+		through the OPAL firmware interface.
+
+		Each error log is identified by a unique ID and will
+		exist until explicitly acknowledged to firmware.
+
+		Each log entry has a directory in /sys/firmware/opal/elog.
+
+		Log entries may be purged by the service processor
+		before retrieved by firmware or retrieved/acknowledged by
+		Linux if there is no room for more log entries.
+
+		In the event that Linux has retrieved the log entries
+		but not explicitly acknowledged them to firmware and
+		the service processor needs more room for log entries,
+		the only remaining copy of a log message may be in
+		Linux.
+
+		Typically, a user space daemon will monitor for new
+		entries, read them out and acknowledge them.
+
+		The service processor may be able to store more log
+		entries than firmware can, so after you acknowledge
+		an event from Linux you may instantly get another one
+		from the queue that was generated some time in the past.
+
+		The raw log format is a binary format. We currently
+		do not parse this at all in kernel, leaving it up to
+		user space to solve the problem. In future, we may
+		do more parsing in kernel and add more files to make
+		it easier for simple user space processes to extract
+		more information.
+
+		For each log entry (directory), there are the following
+		files:
+
+		id:		An ASCII representation of the ID of the
+				error log, in hex - e.g. "0x01".
+
+		type:		An ASCII representation of the type id and
+				description of the type of error log.
+				Currently just "0x00 PEL" - platform error log.
+				In the future there may be additional types.
+
+		raw:		A read-only binary file that can be read
+				to get the raw log entry. These are
+				<16kb, often just hundreds of bytes and
+				"average" 2kb.
+
+		acknowledge:	Writing 'ack' to this file will acknowledge
+				the error log to firmware (and in turn
+				the service processor, if applicable).
+				Shortly after acknowledging it, the log
+				entry will be removed from sysfs.
+				Reading this file will list the supported
+				operations (curently just acknowledge).

+		stack for a performance advantage when possible.  A value of
+		'1' indicates the feature is enabled, and the controller may
+		use the direct i/o path to physical devices.  A value of zero
+		means the feature is disabled and the controller may not use
+		the direct i/o path to physical devices.  This setting is
+		controller wide, affecting all configured logical drives on the
+		controller.  This file is readable and writable.

+Description:
+		The /sys/devices/.../power/pm_qos_latency_tolerance_us attribute
+		contains the PM QoS active state latency tolerance limit for the
+		given device in microseconds.  That is the maximum memory access
+		latency the device can suffer without any visible adverse
+		effects on user space functionality.  If that value is the
+		string "any", the latency does not matter to user space at all,
+		but hardware should not be allowed to set the latency tolerance
+		for the device automatically.
+
+		Reading "auto" from this file means that the maximum memory
+		access latency for the device may be determined automatically
+		by the hardware as needed.  Writing "auto" to it allows the
+		hardware to be switched to this mode if there are no other
+		latency tolerance requirements from the kernel side.
+
+		This attribute is only present if the feature controlled by it
+		is supported by the hardware.

+		devices and on system-wide suspend/resume and hibernation.

+		It is possible for multiple device-tree directories to exist.
+		Some device drivers use a separate detached device tree which
+		have no attachment to the system tree and will appear in a
+		different subdirectory under /sys/firmware/devicetree.
+
+		Userspace must not use the /sys/firmware/devicetree/base
+		path directly, but instead should follow /proc/device-tree
+		symlink. It is possible that the absolute path will change
+		in the future, but the symlink is the stable ABI.
+
+		The /proc/device-tree symlink replaces the devicetree /proc
+		filesystem support, and has largely the same semantics and
+		should be compatible with existing userspace.
+
+		The contents of /sys/firmware/devicetree/ is a
+		hierarchy of directories, one per device tree node. The
+		directory name is the resolved path component name (node
+		name plus address). Properties are represented as files
+		in the directory. The contents of each file is the exact
+		binary data from the device tree.

+This describes the in kernel data structure for DRBD-9. Starting with
+Linux v3.14 we are reorganizing DRBD to use this data structure.
+
+Basic Data Structure
+====================
+
+A node has a number of DRBD resources.  Each such resource has a number of
+devices (aka volumes) and connections to other nodes ("peer nodes"). Each DRBD
+device is represented by a block device locally.
+
+The DRBD objects are interconnected to form a matrix as depicted below; a
+drbd_peer_device object sits at each intersection between a drbd_device and a
+drbd_connection:
+
+  /--------------+---------------+.....+---------------\
+  |   resource   |    device     |     |    device     |
+  +--------------+---------------+.....+---------------+
+  |  connection  |  peer_device  |     |  peer_device  |
+  +--------------+---------------+.....+---------------+
+  :              :               :     :               :
+  :              :               :     :               :
+  +--------------+---------------+.....+---------------+
+  |  connection  |  peer_device  |     |  peer_device  |
+  \--------------+---------------+.....+---------------/
+
+In this table, horizontally, devices can be accessed from resources by their
+volume number.  Likewise, peer_devices can be accessed from connections by
+their volume number.  Objects in the vertical direction are connected by double
+linked lists.  There are back pointers from peer_devices to their connections a
+devices, and from connections and devices to their resource.
+
+All resources are in the drbd_resources double-linked list.  In addition, all
+devices can be accessed by their minor device number via the drbd_devices idr.
+
+The drbd_resource, drbd_connection, and drbd_device objects are reference
+counted.  The peer_device objects only serve to establish the links between
+devices and connections; their lifetime is determined by the lifetime of the
+device and connection which they reference.

+Once the pool's metadata device is repaired it may be resized, which

+is flagged as needing repair, the pool's data and metadata devices
+cannot be resized until repair is performed.  It should also be noted
+that when the pool's metadata space is exhausted the current metadata
+transaction is aborted.  Given that the pool will cache IO whose
+completion may have already been acknowledged to upper IO layers

+Common bindings for device graphs
+
+General concept
+---------------
+
+The hierarchical organisation of the device tree is well suited to describe
+control flow to devices, but there can be more complex connections between
+devices that work together to form a logical compound device, following an
+arbitrarily complex graph.
+There already is a simple directed graph between devices tree nodes using
+phandle properties pointing to other nodes to describe connections that
+can not be inferred from device tree parent-child relationships. The device
+tree graph bindings described herein abstract more complex devices that can
+have multiple specifiable ports, each of which can be linked to one or more
+ports of other devices.
+
+These common bindings do not contain any information about the direction or
+type of the connections, they just map their existence. Specific properties
+may be described by specialized bindings depending on the type of connection.
+
+To see how this binding applies to video pipelines, for example, see
+Documentation/device-tree/bindings/media/video-interfaces.txt.
+Here the ports describe data interfaces, and the links between them are
+the connecting data buses. A single port with multiple connections can
+correspond to multiple devices being connected to the same physical bus.
+
+Organisation of ports and endpoints
+-----------------------------------
+
+Ports are described by child 'port' nodes contained in the device node.
+Each port node contains an 'endpoint' subnode for each remote device port
+connected to this port. If a single port is connected to more than one
+remote device, an 'endpoint' child node must be provided for each link.
+If more than one port is present in a device node or there is more than one
+endpoint at a port, or a port node needs to be associated with a selected
+hardware interface, a common scheme using '#address-cells', '#size-cells'
+and 'reg' properties is used number the nodes.
+
+device {
+        ...
+        #address-cells = <1>;
+        #size-cells = <0>;
+
+        port@0 {
+	        #address-cells = <1>;
+	        #size-cells = <0>;
+		reg = <0>;
+
+                endpoint@0 {
+			reg = <0>;
+			...
+		};
+                endpoint@1 {
+			reg = <1>;
+			...
+		};
+        };
+
+        port@1 {
+		reg = <1>;
+
+		endpoint { ... };
+	};
+};
+
+All 'port' nodes can be grouped under an optional 'ports' node, which
+allows to specify #address-cells, #size-cells properties for the 'port'
+nodes independently from any other child device nodes a device might
+have.
+
+device {
+        ...
+        ports {
+                #address-cells = <1>;
+                #size-cells = <0>;
+
+                port@0 {
+                        ...
+                        endpoint@0 { ... };
+                        endpoint@1 { ... };
+                };
+
+                port@1 { ... };
+        };
+};
+
+Links between endpoints
+-----------------------
+
+Each endpoint should contain a 'remote-endpoint' phandle property that points
+to the corresponding endpoint in the port of the remote device. In turn, the
+remote endpoint should contain a 'remote-endpoint' property. If it has one,
+it must not point to another than the local endpoint. Two endpoints with their
+'remote-endpoint' phandles pointing at each other form a link between the
+containing ports.
+
+device-1 {
+        port {
+                device_1_output: endpoint {
+                        remote-endpoint = <&device_2_input>;
+                };
+        };
+};
+
+device-2 {
+        port {
+                device_2_input: endpoint {
+                        remote-endpoint = <&device_1_output>;
+                };
+        };
+};
+
+
+Required properties
+-------------------
+
+If there is more than one 'port' or more than one 'endpoint' node or 'reg'
+property is present in port and/or endpoint nodes the following properties
+are required in a relevant parent node:
+
+ - #address-cells : number of cells required to define port/endpoint
+                    identifier, should be 1.
+ - #size-cells    : should be zero.
+
+Optional endpoint properties
+----------------------------
+
+- remote-endpoint: phandle to an 'endpoint' subnode of a remote device node.

+Xilinx XADC device driver
+
+This binding document describes the bindings for both of them since the
+bindings are very similar. The Xilinx XADC is a ADC that can be found in the
+series 7 FPGAs from Xilinx. The XADC has a DRP interface for communication.
+Currently two different frontends for the DRP interface exist. One that is only
+available on the ZYNQ family as a hardmacro in the SoC portion of the ZYNQ. The
+other one is available on all series 7 platforms and is a softmacro with a AXI
+interface. This binding document describes the bindings for both of them since
+the bindings are very similar.
+
+Required properties:
+	- compatible: Should be one of
+		* "xlnx,zynq-xadc-1.00.a": When using the ZYNQ device
+		  configuration interface to interface to the XADC hardmacro.
+		* "xlnx,axi-xadc-1.00.a": When using the axi-xadc pcore to
+		  interface to the XADC hardmacro.
+	- reg: Address and length of the register set for the device
+	- interrupts: Interrupt for the XADC control interface.
+	- clocks: When using the ZYNQ this must be the ZYNQ PCAP clock,
+	  when using the AXI-XADC pcore this must be the clock that provides the
+	  clock to the AXI bus interface of the core.
+
+Optional properties:
+	- interrupt-parent: phandle to the parent interrupt controller
+	- xlnx,external-mux:
+		* "none": No external multiplexer is used, this is the default
+		  if the property is omitted.
+		* "single": External multiplexer mode is used with one
+		   multiplexer.
+		* "dual": External multiplexer mode is used with two
+		  multiplexers for simultaneous sampling.
+	- xlnx,external-mux-channel: Configures which pair of pins is used to
+	  sample data in external mux mode.
+	  Valid values for single external multiplexer mode are:
+		0: VP/VN
+		1: VAUXP[0]/VAUXN[0]
+		2: VAUXP[1]/VAUXN[1]
+		...
+		16: VAUXP[15]/VAUXN[15]
+	  Valid values for dual external multiplexer mode are:
+		1: VAUXP[0]/VAUXN[0] - VAUXP[8]/VAUXN[8]
+		2: VAUXP[1]/VAUXN[1] - VAUXP[9]/VAUXN[9]
+		...
+		8: VAUXP[7]/VAUXN[7] - VAUXP[15]/VAUXN[15]
+
+	  This property needs to be present if the device is configured for
+	  external multiplexer mode (either single or dual). If the device is
+	  not using external multiplexer mode the property is ignored.
+	- xnlx,channels: List of external channels that are connected to the ADC
+	  Required properties:
+		* #address-cells: Should be 1.
+		* #size-cells: Should be 0.
+
+	  The child nodes of this node represent the external channels which are
+	  connected to the ADC. If the property is no present no external
+	  channels will be assumed to be connected.
+
+	  Each child node represents one channel and has the following
+	  properties:
+		Required properties:
+			* reg: Pair of pins the the channel is connected to.
+				0: VP/VN
+				1: VAUXP[0]/VAUXN[0]
+				2: VAUXP[1]/VAUXN[1]
+				...
+				16: VAUXP[15]/VAUXN[15]
+			  Note each channel number should only be used at most
+			  once.
+		Optional properties:
+			* xlnx,bipolar: If set the channel is used in bipolar
+			  mode.

+* Device tree bindings for Texas instruments AEMIF controller
+
+The Async External Memory Interface (EMIF16/AEMIF) controller is intended to
+provide a glue-less interface to a variety of asynchronous memory devices like
+ASRA M, NOR and NAND memory. A total of 256M bytes of any of these memories
+can be accessed at any given time via four chip selects with 64M byte access
+per chip select. Synchronous memories such as DDR1 SD RAM, SDR SDRAM
+and Mobile SDR are not supported.
+
+Documentation:
+Davinci DM646x - http://www.ti.com/lit/ug/sprueq7c/sprueq7c.pdf

+* Samsung S2MPA01 Voltage and Current Regulator
+
+The Samsung S2MPA01 is a multi-function device which includes high
+efficiency buck converters including Dual-Phase buck converter, various LDOs,
+and an RTC. It is interfaced to the host controller using an I2C interface.
+Each sub-block is addressed by the host system using different I2C slave
+addresses.
+
+Required properties:
+- compatible: Should be "samsung,s2mpa01-pmic".
+- reg: Specifies the I2C slave address of the PMIC block. It should be 0x66.
+
+Optional properties:
+- interrupt-parent: Specifies the phandle of the interrupt controller to which
+  the interrupts from s2mpa01 are delivered to.
+- interrupts: An interrupt specifier for the sole interrupt generated by the
+  device.
+
+Optional nodes:
+- regulators: The regulators of s2mpa01 that have to be instantiated should be
+  included in a sub-node named 'regulators'. Regulator nodes and constraints
+  included in this sub-node use the standard regulator bindings which are
+  documented elsewhere.
+
+Properties for BUCK regulator nodes:
+- regulator-ramp-delay: ramp delay in uV/us. May be 6250, 12500
+  (default), 25000, or 50000. May be 0 for disabling the ramp delay on
+  BUCK{1,2,3,4}.
+
+ In the absence of the regulator-ramp-delay property, the default ramp
+ delay will be used.
+
+  NOTE: Some BUCKs share the ramp rate setting i.e. same ramp value will be set
+  for a particular group of BUCKs. So provide same regulator-ramp-delay=<value>.
+
+  The following BUCKs share ramp settings:
+  * 1 and 6
+  * 2 and 4
+  * 8, 9, and 10
+
+The following are the names of the regulators that the s2mpa01 PMIC block

+Samsung S5P/EXYNOS SoC series USB PHY
+-------------------------------------------------

+Required properties:
+- compatible : should be one of the listed compatibles:
+	- "samsung,exynos4210-usb2-phy"
+	- "samsung,exynos4x12-usb2-phy"
+	- "samsung,exynos5250-usb2-phy"
+- reg : a list of registers used by phy driver

+- samsung,sysreg-phandle - handle to syscon used to control the system registers
+- samsung,pmureg-phandle - handle to syscon used to control PMU registers
+- #phy-cells : from the generic phy bindings, must be 1;
+- clocks and clock-names:
+	- the "phy" clock is required by the phy module, used as a gate
+	- the "ref" clock is used to get the rate of the clock provided to the
+	  PHY module
+
+The first phandle argument in the PHY specifier identifies the PHY, its
+meaning is compatible dependent. For the currently supported SoCs (Exynos 4210
+and Exynos 4212) it is as follows:
+  0 - USB device ("device"),
+  1 - USB host ("host"),
+  2 - HSIC0 ("hsic0"),
+  3 - HSIC1 ("hsic1"),
+
+Exynos 4210 and Exynos 4212 use mode switching and require that mode switch
+register is supplied.
+
+Example:
+
+For Exynos 4412 (compatible with Exynos 4212):
+
+usbphy: phy@125b0000 {
+	compatible = "samsung,exynos4x12-usb2-phy";
+	reg = <0x125b0000 0x100>;
+	clocks = <&clock 305>, <&clock 2>;
+	clock-names = "phy", "ref";
+	status = "okay";
+	#phy-cells = <1>;
+	samsung,sysreg-phandle = <&sys_reg>;
+	samsung,pmureg-phandle = <&pmu_reg>;
+};
+
+Then the PHY can be used in other nodes such as:
+
+phy-consumer@12340000 {
+	phys = <&usbphy 2>;
+	phy-names = "phy";
+};
+
+Refer to DT bindings documentation of particular PHY consumer devices for more
+information about required PHYs and the way of specification.

+*** Reserved memory regions ***
+
+Reserved memory is specified as a node under the /reserved-memory node.
+The operating system shall exclude reserved memory from normal usage
+one can create child nodes describing particular reserved (excluded from
+normal use) memory regions. Such memory regions are usually designed for
+the special usage by various device drivers.
+
+Parameters for each memory region can be encoded into the device tree
+with the following nodes:
+
+/reserved-memory node
+---------------------
+#address-cells, #size-cells (required) - standard definition
+    - Should use the same values as the root node
+ranges (required) - standard definition
+    - Should be empty
+
+/reserved-memory/ child nodes
+-----------------------------
+Each child of the reserved-memory node specifies one or more regions of
+reserved memory. Each child node may either use a 'reg' property to
+specify a specific range of reserved memory, or a 'size' property with
+optional constraints to request a dynamically allocated block of memory.
+
+Following the generic-names recommended practice, node names should
+reflect the purpose of the node (ie. "framebuffer" or "dma-pool"). Unit
+address (@<address>) should be appended to the name if the node is a
+static allocation.
+
+Properties:
+Requires either a) or b) below.
+a) static allocation
+   reg (required) - standard definition
+b) dynamic allocation
+   size (required) - length based on parent's #size-cells
+                   - Size in bytes of memory to reserve.
+   alignment (optional) - length based on parent's #size-cells
+                        - Address boundary for alignment of allocation.
+   alloc-ranges (optional) - prop-encoded-array (address, length pairs).
+                           - Specifies regions of memory that are
+                             acceptable to allocate from.
+
+If both reg and size are present, then the reg property takes precedence
+and size is ignored.
+
+Additional properties:
+compatible (optional) - standard definition
+    - may contain the following strings:
+        - shared-dma-pool: This indicates a region of memory meant to be
+          used as a shared pool of DMA buffers for a set of devices. It can
+          be used by an operating system to instanciate the necessary pool
+          management subsystem if necessary.
+        - vendor specific string in the form <vendor>,[<device>-]<usage>
+no-map (optional) - empty property
+    - Indicates the operating system must not create a virtual mapping
+      of the region as part of its standard mapping of system memory,
+      nor permit speculative access to it under any circumstances other
+      than under the control of the device driver using the region.
+reusable (optional) - empty property
+    - The operating system can use the memory in this region with the
+      limitation that the device driver(s) owning the region need to be
+      able to reclaim it back. Typically that means that the operating
+      system can use that region to store volatile or cached data that
+      can be otherwise regenerated or migrated elsewhere.
+
+Linux implementation note:
+- If a "linux,cma-default" property is present, then Linux will use the
+  region for the default pool of the contiguous memory allocator.
+
+Device node references to reserved memory
+-----------------------------------------
+Regions in the /reserved-memory node may be referenced by other device
+nodes by adding a memory-region property to the device node.
+
+memory-region (optional) - phandle, specifier pairs to children of /reserved-memory
+
+Example
+-------
+This example defines 3 contiguous regions are defined for Linux kernel:
+one default of all device drivers (named linux,cma@72000000 and 64MiB in size),
+one dedicated to the framebuffer device (named framebuffer@78000000, 8MiB), and
+one for multimedia processing (named multimedia-memory@77000000, 64MiB).

+Description
+-----------
+
+This driver implements support for the Texas Instruments ADC128D818.
+It is described as 'ADC System Monitor with Temperature Sensor'.
+
+The ADC128D818 implements one temperature sensor and seven voltage sensors.
+
+Temperatures are measured in degrees Celsius. There is one set of limits.
+When the HOT Temperature Limit is crossed, this will cause an alarm that will
+be reasserted until the temperature drops below the HOT Hysteresis.
+Measurements are guaranteed between -55 and +125 degrees. The temperature
+measurement has a resolution of 0.5 degrees; the limits have a resolution
+of 1 degree.
+
+Voltage sensors (also known as IN sensors) report their values in volts.
+An alarm is triggered if the voltage has crossed a programmable minimum
+or maximum limit. Note that minimum in this case always means 'closest to
+zero'; this is important for negative voltage measurements. All voltage
+inputs can measure voltages between 0 and 2.55 volts, with a resolution
+of 0.625 mV.
+
+If an alarm triggers, it will remain triggered until the hardware register
+is read at least once. This means that the cause for the alarm may
+already have disappeared by the time the alarm is read. The driver
+caches the alarm status for each sensor until it is at least reported
+once, to ensure that alarms are reported to user space.
+
+The ADC128D818 only updates its values approximately once per second;
+reading it more often will do no harm, but will return 'old' values.
+
+In addition to the scanned address list, the chip can also be configured for
+addresses 0x35 to 0x37. Those addresses are not scanned. You have to instantiate
+the driver explicitly if the chip is configured for any of those addresses in
+your system.

+Description
+-----------
+
+The LTC2945  is a rail-to-rail system monitor that measures current, voltage,
+and power consumption.
+
+
+Usage Notes
+-----------
+
+This driver does not probe for LTC2945 devices, since there is no register
+which can be safely used to identify the chip. You will have to instantiate
+the devices explicitly.
+
+Example: the following will load the driver for an LTC2945 at address 0x10
+on I2C bus #1:
+$ modprobe ltc2945
+$ echo ltc2945 0x10 > /sys/bus/i2c/devices/i2c-1/new_device
+
+
+Sysfs entries
+-------------
+
+Voltage readings provided by this driver are reported as obtained from the ADC
+registers. If a set of voltage divider resistors is installed, calculate the
+real voltage by multiplying the reported value with (R1+R2)/R2, where R1 is the
+value of the divider resistor against the measured voltage and R2 is the value
+of the divider resistor against Ground.
+
+Current reading provided by this driver is reported as obtained from the ADC
+Current Sense register. The reported value assumes that a 1 mOhm sense resistor
+is installed. If a different sense resistor is installed, calculate the real
+current by dividing the reported value by the sense resistor value in mOhm.

+Kernel driver ltc4260

+  * Linear Technology LTC4260
+    Prefix: 'ltc4260'

+
+Description
+-----------
+
+The LTC4260 Hot Swap controller allows a board to be safely inserted
+and removed from a live backplane.
+
+
+Usage Notes
+-----------
+
+This driver does not probe for LTC4260 devices, since there is no register
+which can be safely used to identify the chip. You will have to instantiate
+the devices explicitly.
+
+Example: the following will load the driver for an LTC4260 at address 0x10
+on I2C bus #1:
+$ modprobe ltc4260
+$ echo ltc4260 0x10 > /sys/bus/i2c/devices/i2c-1/new_device
+
+
+Sysfs entries
+-------------
+
+Voltage readings provided by this driver are reported as obtained from the ADC
+registers. If a set of voltage divider resistors is installed, calculate the
+real voltage by multiplying the reported value with (R1+R2)/R2, where R1 is the
+value of the divider resistor against the measured voltage and R2 is the value
+of the divider resistor against Ground.
+
+Current reading provided by this driver is reported as obtained from the ADC
+Current Sense register. The reported value assumes that a 1 mOhm sense resistor
+is installed. If a different sense resistor is installed, calculate the real
+current by dividing the reported value by the sense resistor value in mOhm.

+|			Samsung USB 2.0 PHY adaptation layer		       |
++-----------------------------------------------------------------------------+'
+
+| 1. Description
++----------------
+
+The architecture of the USB 2.0 PHY module in Samsung SoCs is similar
+among many SoCs. In spite of the similarities it proved difficult to
+create a one driver that would fit all these PHY controllers. Often
+the differences were minor and were found in particular bits of the
+registers of the PHY. In some rare cases the order of register writes or
+the PHY powering up process had to be altered. This adaptation layer is
+a compromise between having separate drivers and having a single driver
+with added support for many special cases.
+
+| 2. Files description
++----------------------
+
+- phy-samsung-usb2.c
+   This is the main file of the adaptation layer. This file contains
+   the probe function and provides two callbacks to the Generic PHY
+   Framework. This two callbacks are used to power on and power off the
+   phy. They carry out the common work that has to be done on all version
+   of the PHY module. Depending on which SoC was chosen they execute SoC
+   specific callbacks. The specific SoC version is selected by choosing
+   the appropriate compatible string. In addition, this file contains
+   struct of_device_id definitions for particular SoCs.
+
+- phy-samsung-usb2.h
+   This is the include file. It declares the structures used by this
+   driver. In addition it should contain extern declarations for
+   structures that describe particular SoCs.
+
+| 3. Supporting SoCs
++--------------------
+
+To support a new SoC a new file should be added to the drivers/phy
+directory. Each SoC's configuration is stored in an instance of the
+struct samsung_usb2_phy_config.
+
+struct samsung_usb2_phy_config {
+	const struct samsung_usb2_common_phy *phys;
+	int (*rate_to_clk)(unsigned long, u32 *);
+	unsigned int num_phys;
+	bool has_mode_switch;
+};
+
+The num_phys is the number of phys handled by the driver. *phys is an
+array that contains the configuration for each phy. The has_mode_switch
+property is a boolean flag that determines whether the SoC has USB host
+and device on a single pair of pins. If so, a special register has to
+be modified to change the internal routing of these pins between a USB
+device or host module.
+
+For example the configuration for Exynos 4210 is following:
+
+const struct samsung_usb2_phy_config exynos4210_usb2_phy_config = {
+	.has_mode_switch        = 0,
+	.num_phys		= EXYNOS4210_NUM_PHYS,
+	.phys			= exynos4210_phys,
+	.rate_to_clk		= exynos4210_rate_to_clk,
+}
+
+- int (*rate_to_clk)(unsigned long, u32 *)
+	The rate_to_clk callback is to convert the rate of the clock
+	used as the reference clock for the PHY module to the value
+	that should be written in the hardware register.
+
+The exynos4210_phys configuration array is as follows:
+
+static const struct samsung_usb2_common_phy exynos4210_phys[] = {
+	{
+		.label		= "device",
+		.id		= EXYNOS4210_DEVICE,
+		.power_on	= exynos4210_power_on,
+		.power_off	= exynos4210_power_off,
+	},
+	{
+		.label		= "host",
+		.id		= EXYNOS4210_HOST,
+		.power_on	= exynos4210_power_on,
+		.power_off	= exynos4210_power_off,
+	},
+	{
+		.label		= "hsic0",
+		.id		= EXYNOS4210_HSIC0,
+		.power_on	= exynos4210_power_on,
+		.power_off	= exynos4210_power_off,
+	},
+	{
+		.label		= "hsic1",
+		.id		= EXYNOS4210_HSIC1,
+		.power_on	= exynos4210_power_on,
+		.power_off	= exynos4210_power_off,
+	},
+	{},
+};
+
+- int (*power_on)(struct samsung_usb2_phy_instance *);
+- int (*power_off)(struct samsung_usb2_phy_instance *);
+	These two callbacks are used to power on and power off the phy
+	by modifying appropriate registers.
+
+Final change to the driver is adding appropriate compatible value to the
+phy-samsung-usb2.c file. In case of Exynos 4210 the following lines were
+added to the struct of_device_id samsung_usb2_phy_of_match[] array:
+
+#ifdef CONFIG_PHY_EXYNOS4210_USB2
+	{
+		.compatible = "samsung,exynos4210-usb2-phy",
+		.data = &exynos4210_usb2_phy_config,
+	},
+#endif
+
+To add further flexibility to the driver the Kconfig file enables to
+include support for selected SoCs in the compiled driver. The Kconfig
+entry for Exynos 4210 is following:
+
+config PHY_EXYNOS4210_USB2
+	bool "Support for Exynos 4210"
+	depends on PHY_SAMSUNG_USB2
+	depends on CPU_EXYNOS4210
+	help
+	  Enable USB PHY support for Exynos 4210. This option requires that
+	  Samsung USB 2.0 PHY driver is enabled and means that support for this
+	  particular SoC is compiled in the driver. In case of Exynos 4210 four
+	  phys are available - device, host, HSCI0 and HSCI1.
+
+The newly created file that supports the new SoC has to be also added to the
+Makefile. In case of Exynos 4210 the added line is following:
+
+obj-$(CONFIG_PHY_EXYNOS4210_USB2)       += phy-exynos4210-usb2.o
+
+After completing these steps the support for the new SoC should be ready.

+Active state latency tolerance
+
+This device PM QoS type is used to support systems in which hardware may switch
+to energy-saving operation modes on the fly.  In those systems, if the operation
+mode chosen by the hardware attempts to save energy in an overly aggressive way,
+it may cause excess latencies to be visible to software, causing it to miss
+certain protocol requirements or target frame or sample rates etc.
+
+If there is a latency tolerance control mechanism for a given device available
+to software, the .set_latency_tolerance callback in that device's dev_pm_info
+structure should be populated.  The routine pointed to by it is should implement
+whatever is necessary to transfer the effective requirement value to the
+hardware.
+
+Whenever the effective latency tolerance changes for the device, its
+.set_latency_tolerance() callback will be executed and the effective value will
+be passed to it.  If that value is negative, which means that the list of
+latency tolerance requirements for the device is empty, the callback is expected
+to switch the underlying hardware latency tolerance control mechanism to an
+autonomous mode if available.  If that value is PM_QOS_LATENCY_ANY, in turn, and
+the hardware supports a special "no requirement" setting, the callback is
+expected to use it.  That allows software to prevent the hardware from
+automatically updating the device's latency tolerance in response to its power
+state changes (e.g. during transitions from D3cold to D0), which generally may
+be done in the autonomous latency tolerance control mode.
+
+If .set_latency_tolerance() is present for the device, sysfs attribute
+pm_qos_latency_tolerance_us will be present in the devivce's power directory.
+Then, user space can use that attribute to specify its latency tolerance
+requirement for the device, if any.  Writing "any" to it means "no requirement,
+but do not let the hardware control latency tolerance" and writing "auto" to it
+allows the hardware to be switched to the autonomous mode if there are no other
+requirements from the kernel side in the device's list.
+
+Kernel code can use the functions described above along with the
+DEV_PM_QOS_LATENCY_TOLERANCE device PM QoS type to add, remove and update
+latency tolerance requirements for devices.

-vwsnd - Sound driver for the Silicon Graphics 320 and 540 Visual
-Workstations' onboard audio.
-
-Copyright 1999 Silicon Graphics, Inc.  All rights reserved.
-
-
-At the time of this writing, March 1999, there are two models of
-Visual Workstation, the 320 and the 540.  This document only describes
-those models.  Future Visual Workstation models may have different
-sound capabilities, and this driver will probably not work on those
-boxes.
-
-The Visual Workstation has an Analog Devices AD1843 "SoundComm" audio
-codec chip.  The AD1843 is accessed through the Cobalt I/O ASIC, also
-known as Lithium.  This driver programs both chips.
-
-==============================================================================
-QUICK CONFIGURATION
-
-	# insmod soundcore
-	# insmod vwsnd
-
-==============================================================================
-I/O CONNECTIONS
-
-On the Visual Workstation, only three of the AD1843 inputs are hooked
-up.  The analog line in jacks are connected to the AD1843's AUX1
-input.  The CD audio lines are connected to the AD1843's AUX2 input.
-The microphone jack is connected to the AD1843's MIC input.  The mic
-jack is mono, but the signal is delivered to both the left and right
-MIC inputs.  You can record in stereo from the mic input, but you will
-get the same signal on both channels (within the limits of A/D
-accuracy).  Full scale on the Line input is +/- 2.0 V.  Full scale on
-the MIC input is 20 dB less, or +/- 0.2 V.
-
-The AD1843's LOUT1 outputs are connected to the Line Out jacks.  The
-AD1843's HPOUT outputs are connected to the speaker/headphone jack.
-LOUT2 is not connected.  Line out's maximum level is +/- 2.0 V peak to
-peak.  The speaker/headphone out's maximum is +/- 4.0 V peak to peak.
-
-The AD1843's PCM input channel and one of its output channels (DAC1)
-are connected to Lithium.  The other output channel (DAC2) is not
-connected.
-
-==============================================================================
-CAPABILITIES
-
-The AD1843 has PCM input and output (Pulse Code Modulation, also known
-as wavetable).  PCM input and output can be mono or stereo in any of
-four formats.  The formats are 16 bit signed and 8 bit unsigned,
-u-Law, and A-Law format.  Any sample rate from 4 KHz to 49 KHz is
-available, in 1 Hz increments.
-
-The AD1843 includes an analog mixer that can mix all three input
-signals (line, mic and CD) into the analog outputs.  The mixer has a
-separate gain control and mute switch for each input.
-
-There are two outputs, line out and speaker/headphone out.  They
-always produce the same signal, and the speaker always has 3 dB more
-gain than the line out.  The speaker/headphone output can be muted,
-but this driver does not export that function.
-
-The hardware can sync audio to the video clock, but this driver does
-not have a way to specify syncing to video.
-
-==============================================================================
-PROGRAMMING
-
-This section explains the API supported by the driver.  Also see the
-Open Sound Programming Guide at http://www.opensound.com/pguide/ .
-This section assumes familiarity with that document.
-
-The driver has two interfaces, an I/O interface and a mixer interface.
-There is no MIDI or sequencer capability.
-
-==============================================================================
-PROGRAMMING PCM I/O
-
-The I/O interface is usually accessed as /dev/audio or /dev/dsp.
-Using the standard Open Sound System (OSS) ioctl calls, the sample
-rate, number of channels, and sample format may be set within the
-limitations described above.  The driver supports triggering.  It also
-supports getting the input and output pointers with one-sample
-accuracy.
-
-The SNDCTL_DSP_GETCAP ioctl returns these capabilities.
-
-	DSP_CAP_DUPLEX - driver supports full duplex.
-
-	DSP_CAP_TRIGGER - driver supports triggering.
-
-	DSP_CAP_REALTIME - values returned by SNDCTL_DSP_GETIPTR
-	and SNDCTL_DSP_GETOPTR are accurate to a few samples.
-
-Memory mapping (mmap) is not implemented.
-
-The driver permits subdivided fragment sizes from 64 to 4096 bytes.
-The number of fragments can be anything from 3 fragments to however
-many fragments fit into 124 kilobytes.  It is up to the user to
-determine how few/small fragments can be used without introducing
-glitches with a given workload.  Linux is not realtime, so we can't
-promise anything.  (sigh...)
-
-When this driver is switched into or out of mu-Law or A-Law mode on
-output, it may produce an audible click.  This is unavoidable.  To
-prevent clicking, use signed 16-bit mode instead, and convert from
-mu-Law or A-Law format in software.
-
-==============================================================================
-PROGRAMMING THE MIXER INTERFACE
-
-The mixer interface is usually accessed as /dev/mixer.  It is accessed
-through ioctls.  The mixer allows the application to control gain or
-mute several audio signal paths, and also allows selection of the
-recording source.
-
-Each of the constants described here can be read using the
-MIXER_READ(SOUND_MIXER_xxx) ioctl.  Those that are not read-only can
-also be written using the MIXER_WRITE(SOUND_MIXER_xxx) ioctl.  In most
-cases, <sys/soundcard.h> defines constants SOUND_MIXER_READ_xxx and
-SOUND_MIXER_WRITE_xxx which work just as well.
-
-SOUND_MIXER_CAPS	Read-only
-
-This is a mask of optional driver capabilities that are implemented.
-This driver's only capability is SOUND_CAP_EXCL_INPUT, which means
-that only one recording source can be active at a time.
-
-SOUND_MIXER_DEVMASK	Read-only
-
-This is a mask of the sound channels.  This driver's channels are PCM,
-LINE, MIC, CD, and RECLEV.
-
-SOUND_MIXER_STEREODEVS	Read-only
-
-This is a mask of which sound channels are capable of stereo.  All
-channels are capable of stereo.  (But see caveat on MIC input in I/O
-CONNECTIONS section above).
-
-SOUND_MIXER_OUTMASK	Read-only
-
-This is a mask of channels that route inputs through to outputs.
-Those are LINE, MIC, and CD.
-
-SOUND_MIXER_RECMASK	Read-only
-
-This is a mask of channels that can be recording sources.  Those are
-PCM, LINE, MIC, CD.
-
-SOUND_MIXER_PCM		Default: 0x5757 (0 dB)
-
-This is the gain control for PCM output.  The left and right channel
-gain are controlled independently.  This gain control has 64 levels,
-which range from -82.5 dB to +12.0 dB in 1.5 dB steps.  Those 64
-levels are mapped onto 100 levels at the ioctl, see below.
-
-SOUND_MIXER_LINE	Default: 0x4a4a (0 dB)
-
-This is the gain control for mixing the Line In source into the
-outputs.  The left and right channel gain are controlled
-independently.  This gain control has 32 levels, which range from
--34.5 dB to +12.0 dB in 1.5 dB steps.  Those 32 levels are mapped onto
-100 levels at the ioctl, see below.
-
-SOUND_MIXER_MIC		Default: 0x4a4a (0 dB)
-
-This is the gain control for mixing the MIC source into the outputs.
-The left and right channel gain are controlled independently.  This
-gain control has 32 levels, which range from -34.5 dB to +12.0 dB in
-1.5 dB steps.  Those 32 levels are mapped onto 100 levels at the
-ioctl, see below.
-
-SOUND_MIXER_CD		Default: 0x4a4a (0 dB)
-
-This is the gain control for mixing the CD audio source into the
-outputs.  The left and right channel gain are controlled
-independently.  This gain control has 32 levels, which range from
--34.5 dB to +12.0 dB in 1.5 dB steps.  Those 32 levels are mapped onto
-100 levels at the ioctl, see below.
-
-SOUND_MIXER_RECLEV	 Default: 0 (0 dB)
-
-This is the gain control for PCM input (RECording LEVel).  The left
-and right channel gain are controlled independently.  This gain
-control has 16 levels, which range from 0 dB to +22.5 dB in 1.5 dB
-steps.  Those 16 levels are mapped onto 100 levels at the ioctl, see
-below.
-
-SOUND_MIXER_RECSRC	 Default: SOUND_MASK_LINE
-
-This is a mask of currently selected PCM input sources (RECording
-SouRCes).  Because the AD1843 can only have a single recording source
-at a time, only one bit at a time can be set in this mask.  The
-allowable values are SOUND_MASK_PCM, SOUND_MASK_LINE, SOUND_MASK_MIC,
-or SOUND_MASK_CD.  Selecting SOUND_MASK_PCM sets up internal
-resampling which is useful for loopback testing and for hardware
-sample rate conversion.  But software sample rate conversion is
-probably faster, so I don't know how useful that is.
-
-SOUND_MIXER_OUTSRC	DEFAULT: SOUND_MASK_LINE|SOUND_MASK_MIC|SOUND_MASK_CD
-
-This is a mask of sources that are currently passed through to the
-outputs.  Those sources whose bits are not set are muted.
-
-==============================================================================
-GAIN CONTROL
-
-There are five gain controls listed above.  Each has 16, 32, or 64
-steps.  Each control has 1.5 dB of gain per step.  Each control is
-stereo.
-
-The OSS defines the argument to a channel gain ioctl as having two
-components, left and right, each of which ranges from 0 to 100.  The
-two components are packed into the same word, with the left side gain
-in the least significant byte, and the right side gain in the second
-least significant byte.  In C, we would say this.
-
-	#include <assert.h>
-
-	...
-
-	 	assert(leftgain >= 0 && leftgain <= 100);
-		assert(rightgain >= 0 && rightgain <= 100);
-		arg = leftgain | rightgain << 8;
-
-So each OSS gain control has 101 steps.  But the hardware has 16, 32,
-or 64 steps.  The hardware steps are spread across the 101 OSS steps
-nearly evenly.  The conversion formulas are like this, given N equals
-16, 32, or 64.
-
-	int round = N/2 - 1;
-	OSS_gain_steps = (hw_gain_steps * 100 + round) / (N - 1);
-	hw_gain_steps = (OSS_gain_steps * (N - 1) + round) / 100;
-
-Here is a snippet of C code that will return the left and right gain
-of any channel in dB.  Pass it one of the predefined gain_desc_t
-structures to access any of the five channels' gains.
-
-	typedef struct gain_desc {
-		float min_gain;
-		float gain_step;
-		int nbits;
-		int chan;
-	} gain_desc_t;

+FLIC (floating interrupt controller)
+====================================
+
+FLIC handles floating (non per-cpu) interrupts, i.e. I/O, service and some
+machine check interruptions. All interrupts are stored in a per-vm list of
+pending interrupts. FLIC performs operations on this list.
+
+Only one FLIC instance may be instantiated.
+
+FLIC provides support to
+- add interrupts (KVM_DEV_FLIC_ENQUEUE)
+- inspect currently pending interrupts (KVM_FLIC_GET_ALL_IRQS)
+- purge all pending floating interrupts (KVM_DEV_FLIC_CLEAR_IRQS)
+- enable/disable for the guest transparent async page faults
+- register and modify adapter interrupt sources (KVM_DEV_FLIC_ADAPTER_*)
+
+Groups:
+  KVM_DEV_FLIC_ENQUEUE
+    Passes a buffer and length into the kernel which are then injected into
+    the list of pending interrupts.
+    attr->addr contains the pointer to the buffer and attr->attr contains
+    the length of the buffer.
+    The format of the data structure kvm_s390_irq as it is copied from userspace
+    is defined in usr/include/linux/kvm.h.
+
+  KVM_DEV_FLIC_GET_ALL_IRQS
+    Copies all floating interrupts into a buffer provided by userspace.
+    When the buffer is too small it returns -ENOMEM, which is the indication
+    for userspace to try again with a bigger buffer.
+    All interrupts remain pending, i.e. are not deleted from the list of
+    currently pending interrupts.
+    attr->addr contains the userspace address of the buffer into which all
+    interrupt data will be copied.
+    attr->attr contains the size of the buffer in bytes.
+
+  KVM_DEV_FLIC_CLEAR_IRQS
+    Simply deletes all elements from the list of currently pending floating
+    interrupts.  No interrupts are injected into the guest.
+
+  KVM_DEV_FLIC_APF_ENABLE
+    Enables async page faults for the guest. So in case of a major page fault
+    the host is allowed to handle this async and continues the guest.
+
+  KVM_DEV_FLIC_APF_DISABLE_WAIT
+    Disables async page faults for the guest and waits until already pending
+    async page faults are done. This is necessary to trigger a completion interrupt
+    for every init interrupt before migrating the interrupt list.
+
+  KVM_DEV_FLIC_ADAPTER_REGISTER
+    Register an I/O adapter interrupt source. Takes a kvm_s390_io_adapter
+    describing the adapter to register:
+
+struct kvm_s390_io_adapter {
+	__u32 id;
+	__u8 isc;
+	__u8 maskable;
+	__u8 swap;
+	__u8 pad;
+};
+
+   id contains the unique id for the adapter, isc the I/O interruption subclass
+   to use, maskable whether this adapter may be masked (interrupts turned off)
+   and swap whether the indicators need to be byte swapped.
+
+

+ * NOTE: It is a bit of overkill to mark all such methods serialized, since

+ * A blocking operation is, for example, a Sleep() operation, or any access

+ *
+ * ACPICA policy for new _OSI strings:
+ *
+ * It is the stated policy of ACPICA that new _OSI strings will be integrated
+ * into this module as soon as possible after they are defined. It is strongly
+ * recommended that all ACPICA hosts mirror this policy and integrate any
+ * changes to this module as soon as possible. There are several historical
+ * reasons behind this policy:
+ *
+ * 1) New BIOSs tend to test only the case where the host responds TRUE to
+ *    the latest version of Windows, which would respond to the latest/newest
+ *    _OSI string. Not responding TRUE to the latest version of Windows will
+ *    risk executing untested code paths throughout the DSDT and SSDTs.
+ *
+ * 2) If a new _OSI string is recognized only after a significant delay, this
+ *    has the potential to cause problems on existing working machines because
+ *    of the possibility that a new and different path through the ASL code
+ *    will be executed.
+ *
+ * 3) New _OSI strings are tending to come out about once per year. A delay
+ *    in recognizing a new string for a significant amount of time risks the
+ *    release of another string which only compounds the initial problem.
+ *

+ *
+ * Due to the limitation of the hardware PHY, a difference set of setting is
+ * required for each supported disk speed - Gen3 (6.0Gbps), Gen2 (3.0Gbps),
+ * and Gen1 (1.5Gbps). Otherwise during long IO stress test, the PHY will
+ * report disparity error and etc. In addition, during COMRESET, there can
+ * be error reported in the register PORT_SCR_ERR. For SERR_DISPARITY and
+ * SERR_10B_8B_ERR, the PHY receiver line must be reseted. The following
+ * algorithm is followed to proper configure the hardware PHY during COMRESET:
+ *
+ * Alg Part 1:
+ * 1. Start the PHY at Gen3 speed (default setting)
+ * 2. Issue the COMRESET
+ * 3. If no link, go to Alg Part 3
+ * 4. If link up, determine if the negotiated speed matches the PHY
+ *    configured speed
+ * 5. If they matched, go to Alg Part 2
+ * 6. If they do not matched and first time, configure the PHY for the linked
+ *    up disk speed and repeat step 2
+ * 7. Go to Alg Part 2
+ *
+ * Alg Part 2:
+ * 1. On link up, if there are any SERR_DISPARITY and SERR_10B_8B_ERR error
+ *    reported in the register PORT_SCR_ERR, then reset the PHY receiver line
+ * 2. Go to Alg Part 3
+ *
+ * Alg Part 3:
+ * 1. Clear any pending from register PORT_SCR_ERR.
+ *
+ * NOTE: For the initial version, we will NOT support Gen1/Gen2. In addition
+ *       and until the underlying PHY supports an method to reset the receiver
+ *       line, on detection of SERR_DISPARITY or SERR_10B_8B_ERR errors,
+ *       an warning message will be printed.

+ * This bit is configured by "st,ext-phyclk" property.
+ *
+ * ETH_SEL_TXCLK_NOT_CLK125 is only valid for gigabit modes, where the 125Mhz
+ * clock either comes from clk-125 pin or txclk pin. This configuration is

+ *
+ * TXCLK configuration is different for different phy interface modes
+ * and changes according to link speed in modes like RGMII.
+ *
+ * Below table summarizes the clock requirement and clock sources for
+ * supported phy interface modes with link speeds.

+ * The APM X-Gene PHY consists of two PLL clock macro's (CMU) and lanes.
+ * The first PLL clock macro is used for internal reference clock. The second
+ * PLL clock macro is used to generate the clock for the PHY. This driver
+ * configures the first PLL CMU, the second PLL CMU, and programs the PHY to
+ * operate according to the mode of operation. The first PLL CMU is only
+ * required if internal clock is enabled.
+ *
+ * Logical Layer Out Of HW module units:
+ *
+ * -----------------
+ * | Internal      |    |------|
+ * | Ref PLL CMU   |----|      |     -------------    ---------
+ * ------------ ----    | MUX  |-----|PHY PLL CMU|----| Serdes|
+ *                      |      |     |           |    ---------
+ * External Clock ------|      |     -------------
+ *                      |------|
+ *
+ * The Ref PLL CMU CSR (Configuration System Registers) is accessed
+ * indirectly from the SDS offset at 0x2000. It is only required for
+ * internal reference clock.
+ * The PHY PLL CMU CSR is accessed indirectly from the SDS offset at 0x0000.
+ * The Serdes CSR is accessed indirectly from the SDS offset at 0x0400.
+ *
+ * The Ref PLL CMU can be located within the same PHY IP or outside the PHY IP
+ * due to shared Ref PLL CMU. For PHY with Ref PLL CMU shared with another IP,
+ * it is located outside the PHY IP. This is the case for the PHY located
+ * at 0x1f23a000 (SATA Port 4/5). For such PHY, another resource is required
+ * to located the SDS/Ref PLL CMU module and its clock for that IP enabled.
+ *
+ * Currently, this driver only supports Gen3 SATA mode with external clock.

+/*
+ *      In the original out of kernel Digi dgap driver, firmware
+ *      loading was done via user land to driver handshaking.
+ *
+ *      For cards that support a concentrator (port expander),
+ *      I believe the concentrator its self told the card which
+ *      concentrator is actually attached and then that info
+ *      was used to tell user land which concentrator firmware
+ *      image was to be downloaded. I think even the BIOS or
+ *      FEP images required could change with the connection
+ *      of a particular concentrator.
+ *
+ *      Since I have no access to any of these cards or
+ *      concentrators, I cannot put the correct concentrator
+ *      firmware file names into the firmware_info structure
+ *      as is now done for the BIOS and FEP images.
+ *
+ *      I think, but am not certain, that the cards supporting
+ *      concentrators will function without them. So support
+ *      of these cards has been left in this driver.
+ *
+ *      In order to fully support those cards, they would
+ *      either have to be acquired for dissection or maybe
+ *      Digi International could provide some assistance.

+Linux Driver Source for Xilinx FPGA firmware download

+
+TABLE OF CONTENTS.
+
+1.  SUMMARY
+2.  BACKGROUND
+3.  DESIGN
+4.  HOW TO USE
+5.  REFERENCE
+
+1. SUMMARY
+
+	- Download Xilinx FPGA firmware
+	- This module downloads Xilinx FPGA firmware using gpio pins.
+
+2. BACKGROUND
+
+	An FPGA (Field Programmable Gate Array) is a programmable hardware that is
+	used in various applications. Hardware design needs to programmed through
+	a dedicated device or CPU assisted way (serial or parallel).
+	This driver provides a way to download FPGA firmware.
+
+3. DESIGN
+
+	- load Xilinx FPGA bitstream format[1] firmware image file using 
+	  kernel firmware framework, request_firmware()
+	- program the Xilinx FPGA using SelectMAP (parallel) mode [2]
+	- FPGA prgram is done by gpio based bit-banging, as an example
+	- platform independent file: gs_fpgaboot.c
+	- platform dependent file: io.c
+	
+
+4. HOW TO USE
+
+	$ insmod gs_fpga.ko file="xlinx_fpga_top_bitstream.bit"
+	$ rmmod gs_fpga
+
+5. USE CASE (from a mailing list discussion with Greg)
+
+	a. As a FPGA development support tool,
+	During FPGA firmware development, you need to download a new FPGA
+	image frequently.
+	You would do that with a dedicated JTAG, which usually a limited
+	resource in the lab.
+	However, if you use my driver, you don't have to have a dedicated JTAG.
+	This is a real gain :)
+
+	b. For the FPGA that runs without config after the download, which
+	doesn't talk to any of Linux interfaces (such as PCIE).
+
+	We download FPGA firmware from user triggered or some other way, and that's it.
+	Since that FPGA runs on its own, it doesn't require a linux driver
+	after the download.
+
+	c. For the FPGA that requires config after the download, which talk to
+	any of linux interfaces (such as PCIE)
+
+	Then, this type of FPGA config can be put into device tree and have a
+	separate driver (pcie or others), then THAT driver calls my driver to
+	download FPGA firmware during the Linux boot, the take over the device
+	through the interface.
+

 TODO:
 - get DRM Maintainer review for this code
-- Wait for common display framework to hit mainline and update the IPU
-  driver to use it. This will most probably make changes to the devicetree
-  bindings necessary.
-- Factor out more code to common helper functions
 - decide where to put the base driver. It is not specific to a subsystem
   and would be used by DRM/KMS and media/V4L2
 
 Missing features (not necessarily for moving out of staging):
 
-- Add i.MX6 HDMI support
 - Add support for IC (Image converter)
 - Add support for CSI (CMOS Sensor interface)
 - Add support for VDIC (Video Deinterlacer)

+
+Since none of these devices can function without having a valid
+address, the way this should work is that we should not register the
+HCI device when probing the platform device.
+    
+The HCI device should be registered once a valid address has been
+written into the sysfs file. I do not want to play the tricks with
+bringing up the device without a valid address.

+> +     hdev->send = hci_h4p_hci_send_frame;
+    
+It needs to use hdev->setup to load the firmware. I assume the
+firmware only needs to be loaded once. That is exactly what
+hdev->setup does. It gets executed once.

+
+Overview
+
+This document describes the driver set for Unisys Secure Partitioning (s-Par®).
+
+s-Par is firmware that provides hardware partitioning capabilities for
+splitting large-scale Intel x86 servers into multiple isolated
+partitions. s-Par provides a set of para-virtualized device drivers to
+allow guest partitions on the same server to share devices that would
+normally be unsharable; specifically, PCI network interfaces and host
+bus adapters that do not support shared access via SR-IOV. The shared
+device is owned and managed by a small, single-purpose service
+partition, which communicates with each guest partition sharing that
+device through an area of shared memory called a channel. Additional
+drivers provide support interfaces for communicating with s-Par
+services, logging and diagnostics, and accessing the Linux console
+from the s-Par user interface.
+
+The driver stack consists of a set of support modules, a set of bus
+modules, and a set of device driver modules. The support modules
+handle a number of common functions across each of the other
+drivers. The bus modules provide organization for the device driver
+modules, which provide the shared device functionality.
+
+These drivers are for the Unisys virtual PCI hardware model where the
+hypervisor need not intervene (other than normal interrupt handling)
+in the interactions between the client drivers and the virtual adapter
+firmware in the adapter service partition.
+
+Driver Descriptions
+
+Device Modules
+
+The modules in this section handle shared devices and the virtual
+buses required to support them. These modules use functions in and
+depend on the modules described in the support modules section.
+
+visorchipset
+
+The visorchipset module receives device creation and destruction
+events from the Command service partition of s-Par, as well as
+controlling registration of shared device drivers with the s-Par
+driver core. The events received are used to populate other s-Par
+modules with their assigned shared devices. Visorchipset is required
+for shared device drivers to function properly. Visorchipset also
+stores information for handling dump disk device creation during
+kdump.
+
+In operation, the visorchipset module processes device creation and
+destruction messages sent by s-Par's Command service partition through
+a channel. These messages result in creation (or destruction) of each
+virtual bus and virtual device. Each bus and device is also associated
+with a communication channel, which is used to communicate with one or
+more IO service partitions to perform device IO on behalf of the
+guest.
+
+virthba
+
+The virthba module provides access to a shared SCSI host bus adapter
+and one or more disk devices, by proxying SCSI commands between the
+guest and the service partition that owns the shared SCSI adapter,
+using a channel between the guest and the service partition. The disks
+that appear on the shared bus are defined by the s-Par configuration
+and enforced by the service partition, while the guest driver handles
+sending commands and handling responses. Each disk is shared as a
+whole to a guest. Sharing the bus adapter in this way provides
+resiliency; should the device encounter an error, only the service
+partition is rebooted, and the device is reinitialized. This allows
+guests to continue running and to recover from the error.
+
+virtnic
+
+The virtnic module provides a paravirtualized network interface to a
+guest by proxying buffer information between the guest and the service
+partition that owns the shared network interface, using a channel
+between the guest and the service partition. The connectivity of this
+interface with the shared interface and possibly other guest
+partitions is defined by the s-Par configuration and enforced by the
+service partition; the guest driver handles communication and link
+status.
+
+visorserial
+
+The visorserial module allows the console of the linux guest to be
+accessed via the s-Par console serial channel. It creates devices in
+/dev/visorserialclientX which behave like a serial terminal and are
+connected to the diagnostics system in s-Par. By assigning a getty to
+the terminal in the guest, a user could log into and access the guest
+from the s-Par diagnostics SWITCH RUN terminal.
+
+visorbus
+
+The visorbus module handles the bus functions for most functional
+drivers except visorserial, visordiag, virthba, and virtnic. It
+maintains the sysfs subtree /sys/devices/visorbus*/. It is responsible
+for device creation and destruction of the devices on its bus.
+
+visorclientbus
+
+The visorclientbus module forwards the bus functions for virthba, and
+virtnic to the virtpci driver.
+
+virtpci
+
+The virtpci module handles the bus functions for virthba, and virtnic.
+
+s-Par Integration Modules
+
+The modules in this section provide integration with s-Par guest
+partition services like diagnostics and remote desktop. These modules
+depend on functions in the modules described in the support modules
+section.
+
+visorvideoclient
+
+The visorvideoclient module provides functionality for video support
+for the Unisys s-Par Partition Desktop application. The guest OS must
+also have the UEFI GOP protocol enabled for the partition desktop to
+function.  visorconinclient The visorconinclient module provides
+keyboard and mouse support for the Unisys s-Par Partition Desktop
+application.
+
+sparstop
+
+The sparstop module handles requests from the Unisys s-Par platform to
+shutdown the linux guest. It allows a program on the guest to perform
+clean-up functions on the guest before the guest is shut down or
+rebooted using ACPI.
+
+visordiag
+
+This driver provides the ability for the guest to write information
+into the s-Par diagnostics subsystem. It creates a set of devices
+named /dev/visordiag.X which can be written to by the guest to add
+text to the s-Par system log.
+
+Support Modules
+
+The modules described in this section provide functions and
+abstractions to support the modules described in the previous
+sections, to avoid having duplicated functionality.
+
+visornoop
+
+The visornoop module is a placeholder that responds to device
+create/destroy messages that are currently not in use by linux guests.
+
+visoruislib
+
+The visoruislib module is a support library, used to handle requests
+from virtpci.
+
+visorchannelstub
+
+The visorchannelstub module provides support routines for storing and
+retrieving data from a channel.
+
+visorchannel
+
+The visorchannel module is a support library that abstracts reading
+and writing a channel in memory.
+
+visorutil
+
+The visorutil module is a support library required by all other s-Par
+driver modules. Among its features it abstracts reading, writing, and
+manipulating a block of memory.
+
+Minimum Required Driver Set
+
+The drivers required to boot a Linux guest are visorchipset, visorbus,
+visorvideoclient, visorconinclient, visoruislib, visorchannelstub,
+visorchannel, and visorutil. The other drivers are required by the
+product configurations that are currently being marketed.

+entries for the controlvm channel used by visorchipset.
+
+/proc/uislib/platform: This entry is used to display the platform
+number this node is in the system. For some guests, this may be
+invalid.
+
+/proc/visorchipset/chipsetready: This entry is written to by scripts
+to signify that any user level activity has been completed before the
+guest can be considered running and is shown as running in the s-Par
+UI.
+
+Device Entries
+These entries provide status of the devices shared by a service partition.
+
+/proc/uislib/vbus: this is a directory containing entries for each
+virtual bus. Each numbered sub-directory contains an info entry, which
+describes the devices that appear on that bus.
+
+/proc/uislib/cycles_before_wait: This entry is used to tune
+performance, by setting the number of cycles we wait before going idle
+when in polling mode. A longer time will reduce message latency but
+spend more processing time polling.
+
+/proc/uislib/smart_wakeup: This entry is used to tune performance, by
+enabling or disabling smart wakeup.
+
+/proc/virthba/info: This entry contains debugging information for the
+virthba module, including interrupt information and memory usage.
+
+/proc/virthba/enable_ints: This entry controls interrupt use by the
+virthba module. Writing a 0 to this entry will disable interrupts.
+
+/proc/virtnic/info: This entry contains debugging information for the
+virtnic module, including interrupt information, send and receive
+counts, and other device information.
+
+/proc/virtnic/ethX: This is a directory containing entries for each
+virtual NIC. Each named subdirectory contains two entries,
+clientstring and zone.
+
+/proc/virtpci/info: This entry contains debugging information for the
+virtpci module, including virtual PCI bus information and device
+locations.
+
+/proc/virtnic/enable_ints: This entry controls interrupt use by the
+virtnic module. Writing a 0 to this entry will disable interrupts.
+
+Visorconinclient, visordiag, visornoop, visorserialclient, and
+visorvideoclient Entries
+
+The entries in proc for these modules all follow the same
+pattern. Each module has its own proc directory with the same name,
+e.g. visordiag presents a /proc/visordiag directory. Inside of the
+module's directory are a device directory, which contains one numbered
+directory for each device provided by that module. Each device has a
+diag entry that presents the device number and visorbus name for that
+device. The module directory also has a driver/diag entry, which
+reports the corresponding s-Par version number of the driver.
+
+Automated Installation Entries
+
+These entries are used to pass information between the s-Par platform
+and the Linux-based installation and recovery tool. These values are
+read/write, however, the guest can only reset them to 0, or report an
+error status through the installer entry. The values are only set via
+s-Par's firmware interface, to help prevent accidentally booting into
+the tool.
+
+/proc/visorchipset/boottotool: This entry instructs s-Par that the
+next reboot will launch the installation and recovery tool. If set to
+0, the next boot will happen according to the UEFI boot manager
+settings.
+
+/proc/visorchipset/toolaction: This entry indicates the installation
+and recovery tool mode requested for the next boot.
+
+/proc/visorchipset/installer: this entry is used by the installation
+and recovery tool to pass status and result information back to the
+s-Par firmware.
+
+/proc/visorchipset/partition: This directory contains the guest
+partition configuration data for each virtual bus, for use during
+installation and at runtime for s-Par service partitions.

-	  This driver uses ACPI INT3403 device objects. If present, it will

+	  Newer laptops and tablets that use ACPI may have thermal sensors

+	  such sensors, expose the temperature information from these sensors
+	  to userspace via the normal thermal framework. This means that a wide
+	  range of applications and GUI widgets can show this information to
+	  the user or use this information for making decisions. For example,
+	  the Intel Thermal Daemon can use this information to allow the user
+	  to select his laptop to run without turning on the fans.

+ * We need a radix tree for mapping physical addresses of TRBs to which stream
+ * ID they belong to.  We need to do this because the host controller won't tell
+ * us which stream ring the TRB came from.  We could store the stream ID in an
+ * event data TRB, but that doesn't help us for the cancellation case, since the
+ * endpoint may stop before it reaches that event data TRB.
+ *
+ * The radix tree maps the upper portion of the TRB DMA address to a ring
+ * segment that has the same upper portion of DMA addresses.  For example, say I
+ * have segments of size 1KB, that are always 1KB aligned.  A segment may
+ * start at 0x10c91000 and end at 0x10c913f0.  If I use the upper 10 bits, the
+ * key to the stream ID is 0x43244.  I can use the DMA address of the TRB to
+ * pass the radix tree a key to get the right stream ID:
+ *
+ *	0x10c90fff >> 10 = 0x43243
+ *	0x10c912c0 >> 10 = 0x43244
+ *	0x10c91400 >> 10 = 0x43245
+ *
+ * Obviously, only those TRBs with DMA addresses that are within the segment
+ * will make the radix tree return the stream ID for that ring.
+ *
+ * Caveats for the radix tree:
+ *
+ * The radix tree uses an unsigned long as a key pair.  On 32-bit systems, an
+ * unsigned long will be 32-bits; on a 64-bit system an unsigned long will be
+ * 64-bits.  Since we only request 32-bit DMA addresses, we can use that as the

+ * PCI DMA addresses on a 64-bit system).  There might be a problem on 32-bit

- * In Linux, we implement the KVP functionality in two components:
- * 1) The kernel component which is packaged as part of the hv_utils driver
- * is responsible for communicating with the host and responsible for
- * implementing the host/guest protocol. 2) A user level daemon that is
- * responsible for data gathering.
- *
- * Host/Guest Protocol: The host iterates over an index and expects the guest
- * to assign a key name to the index and also return the value corresponding to
- * the key. The host will have atmost one KVP transaction outstanding at any
- * given point in time. The host side iteration stops when the guest returns
- * an error. Microsoft has specified the following mapping of key names to
- * host specified index:
- *
- *	Index		Key Name
- *	0		FullyQualifiedDomainName
- *	1		IntegrationServicesVersion
- *	2		NetworkAddressIPv4
- *	3		NetworkAddressIPv6
- *	4		OSBuildNumber
- *	5		OSName
- *	6		OSMajorVersion
- *	7		OSMinorVersion
- *	8		OSVersion
- *	9		ProcessorArchitecture
- *
- * The Windows host expects the Key Name and Key Value to be encoded in utf16.
- *
- * Guest Kernel/KVP Daemon Protocol: As noted earlier, we implement all of the
- * data gathering functionality in a user mode daemon. The user level daemon
- * is also responsible for binding the key name to the index as well. The
- * kernel and user-level daemon communicate using a connector channel.
- *
- * The user mode component first registers with the
- * the kernel component. Subsequently, the kernel component requests, data
- * for the specified keys. In response to this message the user mode component
- * fills in the value corresponding to the specified key. We overload the
- * sequence field in the cn_msg header to define our KVP message types.
- *
- *
- * The kernel component simply acts as a conduit for communication between the
- * Windows host and the user-level daemon. The kernel component passes up the
- * index received from the Host to the user-level daemon. If the index is
- * valid (supported), the corresponding key as well as its
- * value (both are strings) is returned. If the index is invalid
- * (not supported), a NULL key string is returned.

+ * In Linux, we implement the KVP functionality in two components:
+ * 1) The kernel component which is packaged as part of the hv_utils driver
+ * is responsible for communicating with the host and responsible for
+ * implementing the host/guest protocol. 2) A user level daemon that is
+ * responsible for data gathering.
+ *
+ * Host/Guest Protocol: The host iterates over an index and expects the guest
+ * to assign a key name to the index and also return the value corresponding to
+ * the key. The host will have atmost one KVP transaction outstanding at any
+ * given point in time. The host side iteration stops when the guest returns
+ * an error. Microsoft has specified the following mapping of key names to
+ * host specified index:
+ *
+ *	Index		Key Name
+ *	0		FullyQualifiedDomainName
+ *	1		IntegrationServicesVersion
+ *	2		NetworkAddressIPv4
+ *	3		NetworkAddressIPv6
+ *	4		OSBuildNumber
+ *	5		OSName
+ *	6		OSMajorVersion
+ *	7		OSMinorVersion
+ *	8		OSVersion
+ *	9		ProcessorArchitecture
+ *
+ * The Windows host expects the Key Name and Key Value to be encoded in utf16.
+ *
+ * Guest Kernel/KVP Daemon Protocol: As noted earlier, we implement all of the
+ * data gathering functionality in a user mode daemon. The user level daemon
+ * is also responsible for binding the key name to the index as well. The
+ * kernel and user-level daemon communicate using a connector channel.
+ *
+ * The user mode component first registers with the
+ * the kernel component. Subsequently, the kernel component requests, data
+ * for the specified keys. In response to this message the user mode component
+ * fills in the value corresponding to the specified key. We overload the
+ * sequence field in the cn_msg header to define our KVP message types.
+ *
+ *
+ * The kernel component simply acts as a conduit for communication between the
+ * Windows host and the user-level daemon. The kernel component passes up the
+ * index received from the Host to the user-level daemon. If the index is
+ * valid (supported), the corresponding key as well as its
+ * value (both are strings) is returned. If the index is invalid
+ * (not supported), a NULL key string is returned.

+ * that I chose to treat the registration operation as part of the
+ * KVP operations defined by the host.
+ * Here is the level of compatibility
+ * (between the user level daemon and the kernel KVP driver) that we
+ * will implement:
+ *
+ * An older daemon will always be supported on a newer driver.
+ * A given user level daemon will require a minimal version of the

+# Simple script to update the version of DTC carried by the Linux kernel
+#
+# This script assumes that the dtc and the linux git trees are in the
+# same directory. After building dtc in the dtc directory, it copies the
+# source files and generated source files into the scripts/dtc directory
+# in the kernel and creates a git commit updating them to the new
+# version.
+#
+# Usage: from the top level Linux source tree, run:
+# $ ./scripts/dtc/update-dtc-source.sh
+#
+# The script will change into the dtc tree, build and test dtc, copy the
+# relevant files into the kernel tree and create a git commit. The commit
+# message will need to be modified to reflect the version of DTC being
+# imported
+#
+# TODO:
+# This script is pretty basic, but it is seldom used so a few manual tasks
+# aren't a big deal. If anyone is interested in making it more robust, the
+# the following would be nice:
+# * Actually fail to complete if any testcase fails.
+#   - The dtc "make check" target needs to return a failure
+# * Extract the version number from the dtc repo for the commit message
+# * Build dtc in the kernel tree
+# * run 'make check" on dtc built from the kernel tree

-/*
- * Locking Notes
- *
- *	INC_USE_COUNT and DEC_USE_COUNT keep track of the number of
- *	open descriptors to this driver. They store it in vwsnd_use_count.
- * 	The global device list, vwsnd_dev_list,	is immutable when the IN_USE
- *	is true.
- *
- *	devc->open_lock is a semaphore that is used to enforce the
- *	single reader/single writer rule for /dev/audio.  The rule is
- *	that each device may have at most one reader and one writer.
- *	Open will block until the previous client has closed the
- *	device, unless O_NONBLOCK is specified.
- *
- *	The semaphore devc->io_mutex serializes PCM I/O syscalls.  This
- *	is unnecessary in Linux 2.2, because the kernel lock
- *	serializes read, write, and ioctl globally, but it's there,
- *	ready for the brave, new post-kernel-lock world.
- *
- *	Locking between interrupt and baselevel is handled by the
- *	"lock" spinlock in vwsnd_port (one lock each for read and
- *	write).  Each half holds the lock just long enough to see what
- *	area it owns and update its pointers.  See pcm_output() and
- *	pcm_input() for most of the gory stuff.
- *
- *	devc->mix_mutex serializes all mixer ioctls.  This is also
- *	redundant because of the kernel lock.

- * Sample Format Notes
- *
- *	Lithium's DMA engine has two formats: 16-bit 2's complement
- *	and 8-bit unsigned .  16-bit transfers the data unmodified, 2
- *	bytes per sample.  8-bit unsigned transfers 1 byte per sample
- *	and XORs each byte with 0x80.  Lithium can input or output
- *	either mono or stereo in either format.
- *
- *	The AD1843 has four formats: 16-bit 2's complement, 8-bit
- *	unsigned, 8-bit mu-Law and 8-bit A-Law.
- *
- *	This driver supports five formats: AFMT_S8, AFMT_U8,
- *	AFMT_MU_LAW, AFMT_A_LAW, and AFMT_S16_LE.
- *
- *	For AFMT_U8 output, we keep the AD1843 in 16-bit mode, and
- *	rely on Lithium's XOR to translate between U8 and S8.
- *
- *	For AFMT_S8, AFMT_MU_LAW and AFMT_A_LAW output, we have to XOR
- *	the 0x80 bit in software to compensate for Lithium's XOR.
- *	This happens in pcm_copy_{in,out}().
- *

-/*
- * Lithium DMA Notes
- *
- * Lithium has two dedicated DMA channels for audio.  They are known
- * as comm1 and comm2 (communication areas 1 and 2).  Comm1 is for
- * input, and comm2 is for output.  Each is controlled by three
- * registers: BASE (base address), CFG (config) and CCTL
- * (config/control).
- *
- * Each DMA channel points to a physically contiguous ring buffer in
- * main memory of up to 8 Kbytes.  (This driver always uses 8 Kb.)
- * There are three pointers into the ring buffer: read, write, and
- * trigger.  The pointers are 8 bits each.  Each pointer points to
- * 32-byte "chunks" of data.  The DMA engine moves 32 bytes at a time,
- * so there is no finer-granularity control.
- *
- * In comm1, the hardware updates the write ptr, and software updates
- * the read ptr.  In comm2, it's the opposite: hardware updates the
- * read ptr, and software updates the write ptr.  I designate the
- * hardware-updated ptr as the hwptr, and the software-updated ptr as
- * the swptr.
- *
- * The trigger ptr and trigger mask are used to trigger interrupts.
- * From the Lithium spec, section 5.6.8, revision of 12/15/1998:
- *
- *	Trigger Mask Value
- *
- *	A three bit wide field that represents a power of two mask
- *	that is used whenever the trigger pointer is compared to its
- *	respective read or write pointer.  A value of zero here
- *	implies a mask of 0xFF and a value of seven implies a mask
- *	0x01.  This value can be used to sub-divide the ring buffer
- *	into pie sections so that interrupts monitor the progress of
- *	hardware from section to section.
- *
- * My interpretation of that is, whenever the hw ptr is updated, it is
- * compared with the trigger ptr, and the result is masked by the
- * trigger mask.  (Actually, by the complement of the trigger mask.)
- * If the result is zero, an interrupt is triggered.  I.e., interrupt
- * if ((hwptr & ~mask) == (trptr & ~mask)).  The mask is formed from
- * the trigger register value as mask = (1 << (8 - tmreg)) - 1.
- *
- * In yet different words, setting tmreg to 0 causes an interrupt after
- * every 256 DMA chunks (8192 bytes) or once per traversal of the
- * ring buffer.  Setting it to 7 caues an interrupt every 2 DMA chunks
- * (64 bytes) or 128 times per traversal of the ring buffer.

 'NAME' specifies the name of this argument (optional). You can use the name of local variable, local data structure member (e.g. var->field, var.field2), local array with fixed index (e.g. array[1], var->array[0], var->pointer[2]), or kprobe-tracer argument format (e.g. $retval, %ax, etc). Note that the name of this argument will be set as the last member name if you specify a local data structure member (e.g. field2 for 'var->field1.field2'.)
 'TYPE' casts the type of this argument (optional). If omitted, perf probe automatically set the type based on debuginfo. You can specify 'string' type only for the local variable or structure member which is an array of or a pointer to 'char' or 'unsigned char' type.
