- *	In libata, a port contains links and a link contains devices.

- *	and slave.
- *
- *	However, there are a few controllers which don't fit into this

- *	interface with both master and slave devices but also have
- *	separate SCR register sets for each device.  These controllers
- *	need separate links for physical link handling
- *	(e.g. onlineness, link speed) but should be treated like a
- *	traditional M/S controller for everything else (e.g. command

- *	link is used for both master and slave.  For physical link
- *	handling, separate @ap->slave_link is used.  All dirty details
- *	are implemented inside libata core layer.  From LLD's POV, the
- *	only difference is that prereset, hardreset and postreset are
- *	called once more for the slave link, so the reset sequence
- *	looks like the following.
- *
- *	prereset(M) -> prereset(S) -> hardreset(M) -> hardreset(S) ->
- *	softreset(M) -> postreset(M) -> postreset(S)
- *

+ *	interface with both master and slave devices but also have
+ *	separate SCR register sets for each device.  These controllers
+ *	need separate links for physical link handling

- * Copyright (C) 1999 Stephane Eranian <eranian@hpl.hp.com>
- *
- * Based on skeleton from the drivers/char/rtc.c driver by P. Gortmaker
- *
- * This code provides an architected & portable interface to the real time
- * clock by using EFI instead of direct bit fiddling. The functionalities are 
- * quite different from the rtc.c driver. The only way to talk to the device 
- * is by using ioctl(). There is a /proc interface which provides the raw 
- * information.
- *
- * Please note that we have kept the API as close as possible to the
- * legacy RTC. The standard /sbin/hwclock program should work normally 
- * when used to get/set the time.
- *
- * NOTES:
- *	- Locking is required for safe execution of EFI calls with regards
- *	  to interrupts and SMP.
- *
- * TODO (December 1999):
- * 	- provide the API to set/get the WakeUp Alarm (different from the
- *	  rtc.c alarm).
- *	- SMP testing
- * 	- Add module support

- *	Real Time Clock interface for Linux
- *
- *	Copyright (C) 1996 Paul Gortmaker
- *
- *	This driver allows use of the real time clock (built into
- *	nearly all computers) from user space. It exports the /dev/rtc
- *	interface supporting various ioctl() and also the
- *	/proc/driver/rtc pseudo-file for status information.
- *
- *	The ioctls can be used to set the interrupt behaviour and
- *	generation rate from the RTC via IRQ 8. Then the /dev/rtc
- *	interface can be used to make use of these timer interrupts,
- *	be they interval or alarm based.
- *
- *	The /dev/rtc interface will block on reads until an interrupt
- *	has been received. If a RTC interrupt has already happened,
- *	it will output an unsigned long and then block. The output value
- *	contains the interrupt status in the low byte and the number of
- *	interrupts since the last read in the remaining high bytes. The
- *	/dev/rtc interface can also be used with the select(2) call.
- *
- *	Based on other minimal char device drivers, like Alan's
- *	watchdog, Ted's random, etc. etc.
- *

- *
- * In effect we define a tail pointer for reading that lags the real tail

- * To manage this we actually track two tail pointers:

- *     it is considered 'aged'.
- *  2) An 'aged' tail that can be used for read()ing.
- *
- * The two separate pointers let us decouple read()s from tail pointer aging.

- * The tail pointers are checked and updated at a limited rate within a hrtimer
- * callback (the same callback that is used for delivering EPOLLIN events)

+ * On some Intel PCIe bridge controllers doing a
+ * D0 -> D3hot -> D3cold -> D0 sequence causes Nvidia GPUs to not reappear.
+ * Skipping the intermediate D3hot step seems to make it work again. This is
+ * probably caused by not meeting the expectation the involved AML code has
+ * when the GPU is put into D3hot state before invoking it.
+ *
+ * This leads to various manifestations of this issue:
+ *  - AML code execution to power on the GPU hits an infinite loop (as the
+ *    code waits on device memory to change).
+ *  - kernel crashes, as all PCI reads return -1, which most code isn't able
+ *    to handle well enough.
+ *
+ * In all cases dmesg will contain at least one line like this:
+ * 'nouveau 0000:01:00.0: Refused to change power state, currently in D3'
+ * followed by a lot of nouveau timeouts.
+ *
+ * In the \_SB.PCI0.PEG0.PG00._OFF code deeper down writes bit 0x80 to the not
+ * documented PCI config space register 0x248 of the Intel PCIe bridge
+ * controller (0x1901) in order to change the state of the PCIe link between
+ * the PCIe port and the GPU. There are alternative code paths using other
+ * registers, which seem to work fine (executed pre Windows 8):
+ *  - 0xbc bit 0x20 (publicly available documentation claims 'reserved')
+ *  - 0xb0 bit 0x10 (link disable)
+ * Changing the conditions inside the firmware by poking into the relevant
+ * addresses does resolve the issue, but it seemed to be ACPI private memory
+ * and not any device accessible memory at all, so there is no portable way of
+ * changing the conditions.
+ * On a XPS 9560 that means bits [0,3] on \CPEX need to be cleared.
+ *
+ * The only systems where this behavior can be seen are hybrid graphics laptops
+ * with a secondary Nvidia Maxwell, Pascal or Turing GPU. It's unclear whether
+ * this issue only occurs in combination with listed Intel PCIe bridge
+ * controllers and the mentioned GPUs or other devices as well.
+ *
+ * documentation on the PCIe bridge controller can be found in the
+ * "7th Generation Intel® Processor Families for H Platforms Datasheet Volume 2"
+ * Section "12 PCI Express* Controller (x16) Registers"

+tree
+  - Yaml conversions for abandoned drivers
+  - ABI Documentation
+  - Audit driviers/iio/staging/Documentation
+
+- Replace iio_dev->mlock by either a local lock or use
+iio_claim_direct.(Requires analysis of the purpose of the lock.)
+
+- Converting drivers from device tree centric to more generic
+property handlers.
+
+- Refactor old platform_data constructs from drivers and convert it
+to state struct and using property handlers and readers.

+ *   t5 is fixed, and is 6000uS,
+ *   t6 depends on the sensor external clock, and is max 32000 clock periods.
+ * As per sensor datasheet, the external clock must be from 6MHz to 27MHz.
+ * So for any acceptable external clock t6 is always within the range of
+ * 1185 to 5333 uS, and is always less than t5.
+ * For this reason this is always safe to wait (t4 + t5) = 6200 uS, then
+ * initialize the sensor over I2C, and then exit the software standby.
+ *
+ * This start-up time can be optimized a bit more, if we start the writes
+ * over I2C after (t4+t6), but before (t4+t5) expires. But then sensor
+ * initialization over I2C may complete before (t4+t5) expires, and we must
+ * ensure that capture is not started before (t4+t5).
+ *
+ * This delay doesn't account for the power supply startup time. If needed,
+ * this should be taken care of via the regulator framework. E.g. in the

+ * For Page Program, the page size is now available since JESD216 rev A, however
+ * the supported instruction op codes are still not provided.
+ * For Sector Erase commands, this table stores the supported instruction op
+ * codes and the associated sector sizes.
+ * Finally, the Quad Enable Requirements (QER) are also available since JESD216
+ * rev A. The QER bits encode the manufacturer dependent procedure to be

- * - 011b: QE is bit 7 of status register 2. It is set via Write status

+		DPAA FMan erratum A050385 software workaround implementation:
+		align buffers, data start, SG fragment length to avoid FMan DMA
+		splits.
+		FMAN DMA read or writes under heavy traffic load may cause FMAN
+		internal resource leak thus stopping further packet processing.
+		The FMAN internal queue can overflow when FMAN splits single
+		read or write transactions into multiple smaller transactions
+		such that more than 17 AXI transactions are in flight from FMAN
+		to interconnect. When the FMAN internal queue overflows, it can
+		stall further packet processing. The issue can occur with any
+		one of the following three conditions:
+		1. FMAN AXI transaction crosses 4K address boundary (Errata
+		A010022)
+		2. FMAN DMA address for an AXI transaction is not 16 byte
+		aligned, i.e. the last 4 bits of an address are non-zero
+		3. Scatter Gather (SG) frames have more than one SG buffer in
+		the SG list and any one of the buffers, except the last
+		buffer in the SG list has data size that is not a multiple
+		of 16 bytes, i.e., other than 16, 32, 48, 64, etc.
+		With any one of the above three conditions present, there is
+		likelihood of stalled FMAN packet processing, especially under
+		stress with multiple ports injecting line-rate traffic.

+ * DOC: The IPA Generic Software Interface
+ *
+ * The generic software interface (GSI) is an integral component of the IPA,
+ * providing a well-defined communication layer between the AP subsystem
+ * and the IPA core.  The modem uses the GSI layer as well.

+ *		-------------
+ *
+ * In the above diagram, the AP and Modem represent "execution environments"
+ * (EEs), which are independent operating environments that use the IPA for
+ * data transfer.
+ *
+ * Each EE uses a set of unidirectional GSI "channels," which allow transfer
+ * of data to or from the IPA.  A channel is implemented as a ring buffer,
+ * with a DRAM-resident array of "transfer elements" (TREs) available to
+ * describe transfers to or from other EEs through the IPA.  A transfer
+ * element can also contain an immediate command, requesting the IPA perform
+ * actions other than data transfer.
+ *
+ * Each TRE refers to a block of data--also located DRAM.  After writing one
+ * or more TREs to a channel, the writer (either the IPA or an EE) writes a
+ * doorbell register to inform the receiving side how many elements have
+ * been written.
+ *
+ * Each channel has a GSI "event ring" associated with it.  An event ring
+ * is implemented very much like a channel ring, but is always directed from
+ * the IPA to an EE.  The IPA notifies an EE (such as the AP) about channel
+ * events by adding an entry to the event ring associated with the channel.
+ * The GSI then writes its doorbell for the event ring, causing the target
+ * EE to be interrupted.  Each entry in an event ring contains a pointer
+ * to the channel TRE whose completion the event represents.
+ *
+ * Each TRE in a channel ring has a set of flags.  One flag indicates whether
+ * the completion of the transfer operation generates an entry (and possibly
+ * an interrupt) in the channel's event ring.  Other flags allow transfer
+ * elements to be chained together, forming a single logical transaction.
+ * TRE flags are used to control whether and when interrupts are generated
+ * to signal completion of channel transfers.
+ *
+ * Elements in channel and event rings are completed (or consumed) strictly
+ * in order.  Completion of one entry implies the completion of all preceding
+ * entries.  A single completion interrupt can therefore communicate the
+ * completion of many transfers.
+ *
+ * Note that all GSI registers are little-endian, which is the assumed
+ * endianness of I/O space accesses.  The accessor functions perform byte
+ * swapping if needed (i.e., for a big endian CPU).

+ * DOC: GSI Registers
+ *
+ * GSI registers are located within the "gsi" address space defined by Device
+ * Tree.  The offset of each register within that space is specified by
+ * symbols defined below.  The GSI address space is mapped to virtual memory
+ * space in gsi_init().  All GSI registers are 32 bits wide.
+ *
+ * Each register type is duplicated for a number of instances of something.
+ * For example, each GSI channel has its own set of registers defining its
+ * configuration.  The offset to a channel's set of registers is computed
+ * based on a "base" offset plus an additional "stride" amount computed
+ * from the channel's ID.  For such registers, the offset is computed by a
+ * function-like macro that takes a parameter used in the computation.
+ *
+ * The offset of a register dependent on execution environment is computed
+ * by a macro that is supplied a parameter "ee".  The "ee" value is a member
+ * of the gsi_ee_id enumerated type.
+ *
+ * The offset of a channel register is computed by a macro that is supplied a
+ * parameter "ch".  The "ch" value is a channel id whose maximum value is 30
+ * (though the actual limit is hardware-dependent).
+ *
+ * The offset of an event register is computed by a macro that is supplied a
+ * parameter "ev".  The "ev" value is an event id whose maximum value is 15
+ * (though the actual limit is hardware-dependent).

+/**
+ * DOC: GSI Transactions
+ *
+ * A GSI transaction abstracts the behavior of a GSI channel by representing
+ * everything about a related group of IPA commands in a single structure.
+ * (A "command" in this sense is either a data transfer or an IPA immediate
+ * command.)  Most details of interaction with the GSI hardware are managed
+ * by the GSI transaction core, allowing users to simply describe commands
+ * to be performed.  When a transaction has completed a callback function
+ * (dependent on the type of endpoint associated with the channel) allows
+ * cleanup of resources associated with the transaction.
+ *
+ * To perform a command (or set of them), a user of the GSI transaction
+ * interface allocates a transaction, indicating the number of TREs required
+ * (one per command).  If sufficient TREs are available, they are reserved
+ * for use in the transaction and the allocation succeeds.  This way
+ * exhaustion of the available TREs in a channel ring is detected
+ * as early as possible.  All resources required to complete a transaction
+ * are allocated at transaction allocation time.
+ *
+ * Commands performed as part of a transaction are represented in an array
+ * of Linux scatterlist structures.  This array is allocated with the
+ * transaction, and its entries are initialized using standard scatterlist
+ * functions (such as sg_set_buf() or skb_to_sgvec()).
+ *
+ * Once a transaction's scatterlist structures have been initialized, the
+ * transaction is committed.  The caller is responsible for mapping buffers
+ * for DMA if necessary, and this should be done *before* allocating
+ * the transaction.  Between a successful allocation and commit of a
+ * transaction no errors should occur.
+ *
+ * Committing transfers ownership of the entire transaction to the GSI
+ * transaction core.  The GSI transaction code formats the content of
+ * the scatterlist array into the channel ring buffer and informs the
+ * hardware that new TREs are available to process.
+ *
+ * The last TRE in each transaction is marked to interrupt the AP when the
+ * GSI hardware has completed it.  Because transfers described by TREs are
+ * performed strictly in order, signaling the completion of just the last
+ * TRE in the transaction is sufficient to indicate the full transaction
+ * is complete.
+ *
+ * When a transaction is complete, ipa_gsi_trans_complete() is called by the
+ * GSI code into the IPA layer, allowing it to perform any final cleanup
+ * required before the transaction is freed.

+ *
+ * Activities performed at the init stage can be done without requiring
+ * any access to IPA hardware.  Activities performed at the config stage
+ * require the IPA clock to be running, because they involve access
+ * to IPA registers.  The setup stage is performed only after the GSI

+ * commands" using a special interface to the IPA.
+ *
+ * This function, @ipa_setup(), starts the setup stage.
+ *
+ * In order for the GSI hardware to be functional it needs firmware to be
+ * loaded (in addition to some other low-level initialization).  This early
+ * GSI initialization can be done either by Trust Zone on the AP or by the
+ * modem.
+ *
+ * If it's done by Trust Zone, the AP loads the GSI firmware and supplies
+ * it to Trust Zone to verify and install.  When this completes, if
+ * verification was successful, the GSI layer is ready and ipa_setup()
+ * implements the setup phase of initialization.
+ *
+ * If the modem performs early GSI initialization, the AP needs to know
+ * when this has occurred.  An SMP2P interrupt is used for this purpose,
+ * and receipt of that interrupt triggers the call to ipa_setup().

+ * DOC: IPA/GSI Configuration Data
+ *
+ * Boot-time configuration data is used to define the configuration of the
+ * IPA and GSI resources to use for a given platform.  This data is supplied
+ * via the Device Tree match table, associated with a particular compatible
+ * string.  The data defines information about resources, endpoints, and
+ * channels.
+ *
+ * Resources are data structures used internally by the IPA hardware.  The
+ * configuration data defines the number (or limits of the number) of various
+ * types of these resources.
+ *
+ * Endpoint configuration data defines properties of both IPA endpoints and
+ * GSI channels.  A channel is a GSI construct, and represents a single
+ * communication path between the IPA and a particular execution environment
+ * (EE), such as the AP or Modem.  Each EE has a set of channels associated
+ * with it, and each channel has an ID unique for that EE.  For the most part
+ * the only GSI channels of concern to this driver belong to the AP
+ *
+ * An endpoint is an IPA construct representing a single channel anywhere
+ * in the system.  An IPA endpoint ID maps directly to an (EE, channel_id)
+ * pair.  Generally, this driver is concerned with only endpoints associated
+ * with the AP, however this will change when support for routing (etc.) is
+ * added.  IPA endpoint and GSI channel configuration data are defined
+ * together, establishing the endpoint_id->(EE, channel_id) mapping.
+ *
+ * Endpoint configuration data consists of three parts:  properties that
+ * are common to IPA and GSI (EE ID, channel ID, endpoint ID, and direction);
+ * properties associated with the GSI channel; and properties associated with
+ * the IPA endpoint.

+ * A GSI channel is a unidirectional means of transferring data to or

+ * up of "transfer elements" (TREs) that specify individual data transfers
+ * or IPA immediate commands.  TREs are filled by the AP, and control
+ * is passed to IPA hardware by writing the last written element
+ * into a doorbell register.
+ *
+ * When data transfer commands have completed the GSI generates an
+ * event (a structure of data) and optionally signals the AP with
+ * an interrupt.  Event structures are implemented by another ring
+ * buffer, directed toward the AP from the IPA.
+ *
+ * The input to a GSI channel is a FIFO of type/length/value (TLV)
+ * elements, and the size of this FIFO limits the number of TREs

+/**
+ * DOC: The IP Accelerator
+ *
+ * This driver supports the Qualcomm IP Accelerator (IPA), which is a
+ * networking component found in many Qualcomm SoCs.  The IPA is connected
+ * to the application processor (AP), but is also connected (and partially
+ * controlled by) other "execution environments" (EEs), such as a modem.
+ *
+ * The IPA is the conduit between the AP and the modem that carries network
+ * traffic.  This driver presents a network interface representing the
+ * connection of the modem to external (e.g. LTE) networks.
+ *
+ * The IPA provides protocol checksum calculation, offloading this work
+ * from the AP.  The IPA offers additional functionality, including routing,
+ * filtering, and NAT support, but that more advanced functionality is not
+ * currently supported.  Despite that, some resources--including routing
+ * tables and filter tables--are defined in this driver because they must
+ * be initialized even when the advanced hardware features are not used.
+ *
+ * There are two distinct layers that implement the IPA hardware, and this
+ * is reflected in the organization of the driver.  The generic software
+ * interface (GSI) is an integral component of the IPA, providing a
+ * well-defined communication layer between the AP subsystem and the IPA
+ * core.  The GSI implements a set of "channels" used for communication
+ * between the AP and the IPA.
+ *
+ * The IPA layer uses GSI channels to implement its "endpoints".  And while
+ * a GSI channel carries data between the AP and the IPA, a pair of IPA
+ * endpoints is used to carry traffic between two EEs.  Specifically, the main
+ * modem network interface is implemented by two pairs of endpoints:  a TX
+ * endpoint on the AP coupled with an RX endpoint on the modem; and another
+ * RX endpoint on the AP receiving data from a TX endpoint on the modem.

+ * The regions within the shared block are bounded by an offset (relative to
+ * the "ipa-shared" memory range) and size found in the IPA_SHARED_MEM_SIZE
+ * register.
+ *
+ * Each region is optionally preceded by one or more 32-bit "canary" values.
+ * These are meant to detect out-of-range writes (if they become corrupted).
+ * A given region (such as a filter or routing table) has the same number
+ * of canaries for all IPA hardware versions.  Still, the number used is
+ * defined in the config data, allowing for generic handling of regions.
+ *
+ * The set of memory regions is defined in configuration data.  They are
+ * subject to these constraints:
+ * - a zero offset and zero size represents and undefined region
+ * - a region's offset is defined to be *past* all "canary" values
+ * - offset must be large enough to account for all canaries
+ * - a region's size may be zero, but may still have canaries
+ * - all offsets must be 8-byte aligned
+ * - most sizes must be a multiple of 8
+ * - modem memory size must be a multiple of 4
+ * - the microcontroller ring offset must be a multiple of 1024

+/**
+ * DOC: AP/Modem QMI Handshake
+ *
+ * The AP and modem perform a "handshake" at initialization time to ensure
+ * both sides know when everything is ready to begin operating.  The AP
+ * driver (this code) uses two QMI handles (endpoints) for this; a client
+ * using a service on the modem, and server to service modem requests (and
+ * to supply an indication message from the AP).  Once the handshake is
+ * complete, the AP and modem may begin IPA operation.  This occurs
+ * only when the AP IPA driver, modem IPA driver, and IPA microcontroller
+ * are ready.
+ *
+ * The QMI service on the modem expects to receive an INIT_DRIVER request from
+ * the AP, which contains parameters used by the modem during initialization.
+ * The AP sends this request as soon as it is knows the modem side service
+ * is available.  The modem responds to this request, and if this response
+ * contains a success result, the AP knows the modem IPA driver is ready.
+ *
+ * The modem is responsible for loading firmware on the IPA microcontroller.
+ * This occurs only during the initial modem boot.  The modem sends a
+ * separate DRIVER_INIT_COMPLETE request to the AP to report that the
+ * microcontroller is ready.  The AP may assume the microcontroller is
+ * ready and remain so (even if the modem reboots) once it has received
+ * and responded to this request.
+ *
+ * There is one final exchange involved in the handshake.  It is required
+ * on the initial modem boot, but optional (but in practice does occur) on
+ * subsequent boots.  The modem expects to receive a final INIT_COMPLETE
+ * indication message from the AP when it is about to begin its normal
+ * operation.  The AP will only send this message after it has received
+ * and responded to an INDICATION_REGISTER request from the modem.
+ *
+ * So in summary:
+ * - Whenever the AP learns the modem has booted and its IPA QMI service
+ *   is available, it sends an INIT_DRIVER request to the modem.  The
+ *   modem supplies a success response when it is ready to operate.
+ * - On the initial boot, the modem sets up the IPA microcontroller, and
+ *   sends a DRIVER_INIT_COMPLETE request to the AP when this is done.
+ * - When the modem is ready to receive an INIT_COMPLETE indication from
+ *   the AP, it sends an INDICATION_REGISTER request to the AP.
+ * - On the initial modem boot, everything is ready when:
+ *	- AP has received a success response from its INIT_DRIVER request
+ *	- AP has responded to a DRIVER_INIT_COMPLETE request
+ *	- AP has responded to an INDICATION_REGISTER request from the modem
+ *	- AP has sent an INIT_COMPLETE indication to the modem
+ * - On subsequent modem boots, everything is ready when:
+ *	- AP has received a success response from its INIT_DRIVER request
+ *	- AP has responded to a DRIVER_INIT_COMPLETE request
+ * - The INDICATION_REGISTER request and INIT_COMPLETE indication are
+ *   optional for non-initial modem boots, and have no bearing on the
+ *   determination of when things are "ready"

+/**
+ * DOC: IPA Registers
+ *
+ * IPA registers are located within the "ipa-reg" address space defined by
+ * Device Tree.  The offset of each register within that space is specified
+ * by symbols defined below.  The address space is mapped to virtual memory
+ * space in ipa_mem_init().  All IPA registers are 32 bits wide.
+ *
+ * Certain register types are duplicated for a number of instances of
+ * something.  For example, each IPA endpoint has an set of registers
+ * defining its configuration.  The offset to an endpoint's set of registers
+ * is computed based on an "base" offset, plus an endpoint's ID multiplied
+ * and a "stride" value for the register.  For such registers, the offset is
+ * computed by a function-like macro that takes a parameter used in the
+ * computation.
+ *
+ * Some register offsets depend on execution environment.  For these an "ee"
+ * parameter is supplied to the offset macro.  The "ee" value is a member of
+ * the gsi_ee enumerated type.
+ *
+ * The offset of a register dependent on endpoint id is computed by a macro
+ * that is supplied a parameter "ep".  The "ep" value is assumed to be less
+ * than the maximum endpoint value for the current hardware, and that will
+ * not exceed IPA_ENDPOINT_MAX.
+ *
+ * The offset of registers related to filter and route tables is computed
+ * by a macro that is supplied a parameter "er".  The "er" represents an
+ * endpoint ID for filters, or a route ID for routes.  For filters, the
+ * endpoint ID must be less than IPA_ENDPOINT_MAX, but is further restricted
+ * because not all endpoints support filtering.  For routes, the route ID
+ * must be less than IPA_ROUTE_MAX.
+ *
+ * The offset of registers related to resource types is computed by a macro
+ * that is supplied a parameter "rt".  The "rt" represents a resource type,
+ * which is is a member of the ipa_resource_type_src enumerated type for
+ * source endpoint resources or the ipa_resource_type_dst enumerated type
+ * for destination endpoint resources.
+ *
+ * Some registers encode multiple fields within them.  For these, each field
+ * has a symbol below defining a field mask that encodes both the position
+ * and width of the field within its register.
+ *
+ * In some cases, different versions of IPA hardware use different offset or
+ * field mask values.  In such cases an inline_function(ipa) is used rather
+ * than a MACRO to define the offset or field mask to use.
+ *
+ * Finally, some registers hold bitmasks representing endpoints.  In such
+ * cases the @available field in the @ipa structure defines the "full" set
+ * of valid bits for the register.

+/**
+ * DOC: IPA SMP2P communication with the modem
+ *
+ * SMP2P is a primitive communication mechanism available between the AP and
+ * the modem.  The IPA driver uses this for two purposes:  to enable the modem
+ * to state that the GSI hardware is ready to use; and to communicate the
+ * state of the IPA clock in the event of a crash.
+ *
+ * GSI needs to have early initialization completed before it can be used.
+ * This initialization is done either by Trust Zone or by the modem.  In the
+ * latter case, the modem uses an SMP2P interrupt to tell the AP IPA driver
+ * when the GSI is ready to use.
+ *
+ * The modem is also able to inquire about the current state of the IPA
+ * clock by trigging another SMP2P interrupt to the AP.  We communicate
+ * whether the clock is enabled using two SMP2P state bits--one to
+ * indicate the clock state (on or off), and a second to indicate the
+ * clock state bit is valid.  The modem will poll the valid bit until it
+ * is set, and at that time records whether the AP has the IPA clock enabled.
+ *
+ * Finally, if the AP kernel panics, we update the SMP2P state bits even if
+ * we never receive an interrupt from the modem requesting this.

+ * DOC: IPA Filter and Route Tables
+ *
+ * The IPA has tables defined in its local shared memory that define filter
+ * and routing rules.  Each entry in these tables contains a 64-bit DMA
+ * address that refers to DRAM (system memory) containing a rule definition.
+ * A rule consists of a contiguous block of 32-bit values terminated with
+ * 32 zero bits.  A special "zero entry" rule consisting of 64 zero bits
+ * represents "no filtering" or "no routing," and is the reset value for
+ * filter or route table rules.  Separate tables (both filter and route)
+ * used for IPv4 and IPv6.  Additionally, there can be hashed filter or
+ * route tables, which are used when a hash of message metadata matches.
+ * Hashed operation is not supported by all IPA hardware.
+ *
+ * Each filter rule is associated with an AP or modem TX endpoint, though
+ * not all TX endpoints support filtering.  The first 64-bit entry in a
+ * filter table is a bitmap indicating which endpoints have entries in
+ * the table.  The low-order bit (bit 0) in this bitmap represents a
+ * special global filter, which applies to all traffic.  This is not
+ * used in the current code.  Bit 1, if set, indicates that there is an
+ * entry (i.e. a DMA address referring to a rule) for endpoint 0 in the
+ * table.  Bit 2, if set, indicates there is an entry for endpoint 1,
+ * and so on.  Space is set aside in IPA local memory to hold as many
+ * filter table entries as might be required, but typically they are not
+ * all used.
+ *
+ * The AP initializes all entries in a filter table to refer to a "zero"
+ * entry.  Once initialized the modem and AP update the entries for
+ * endpoints they "own" directly.  Currently the AP does not use the
+ * IPA filtering functionality.
+ *
+ *                    IPA Filter Table
+ *                 ----------------------
+ * endpoint bitmap | 0x0000000000000048 | Bits 3 and 6 set (endpoints 2 and 5)
+ *                 |--------------------|
+ * 1st endpoint    | 0x000123456789abc0 | DMA address for modem endpoint 2 rule
+ *                 |--------------------|
+ * 2nd endpoint    | 0x000123456789abf0 | DMA address for AP endpoint 5 rule
+ *                 |--------------------|

+ *                 ----------------------
+ *
+ * The set of available route rules is divided about equally between the AP
+ * and modem.  The AP initializes all entries in a route table to refer to
+ * a "zero entry".  Once initialized, the modem and AP are responsible for
+ * updating their own entries.  All entries in a route table are usable,
+ * though the AP currently does not use the IPA routing functionality.

+ * Initialize a coherent DMA allocation containing initialized filter and

+ * filter or route table.
+ *
+ * The first entry in a filter table contains a bitmap indicating which
+ * endpoints contain entries in the table.  In addition to that first entry,
+ * there are at most IPA_FILTER_COUNT_MAX entries that follow.  Filter table
+ * entries are 64 bits wide, and (other than the bitmap) contain the DMA
+ * address of a filter rule.  A "zero rule" indicates no filtering, and
+ * consists of 64 bits of zeroes.  When a filter table is initialized (or
+ * reset) its entries are made to refer to the zero rule.
+ *
+ * Each entry in a route table is the DMA address of a routing rule.  For
+ * routing there is also a 64-bit "zero rule" that means no routing, and
+ * when a route table is initialized or reset, its entries are made to refer
+ * to the zero rule.  The zero rule is shared for route and filter tables.
+ *
+ * Note that the IPA hardware requires a filter or route rule address to be
+ * aligned on a 128 byte boundary.  The coherent DMA buffer we allocate here
+ * has a minimum alignment, and we place the zero rule at the base of that
+ * allocated space.  In ipa_table_init() we verify the minimum DMA allocation

+ * essentially no use of the microcontroller, but it still requires some
+ * initialization.  It needs to be notified in the event the AP crashes.
+ *
+ * The microcontroller can generate two interrupts to the AP.  One interrupt
+ * is used to indicate that a response to a request from the AP is available.
+ * The other is used to notify the AP of the occurrence of an event.  In
+ * addition, the AP can interrupt the microcontroller by writing a register.
+ *
+ * A 128 byte block of structured memory within the IPA SRAM is used together
+ * with these interrupts to implement the communication interface between the
+ * AP and the IPA microcontroller.  Each side writes data to the shared area
+ * before interrupting its peer, which will read the written data in response
+ * to the interrupt.  Some information found in the shared area is currently
+ * unused.  All remaining space in the shared area is reserved, and must not
+ * be read or written by the AP.

+ *  Local device  Link partner

+ *    1     0       0     1     Disabled - but since we do support tx and rx,
+ *				this should resolve to RX only.
+ *
+ * Hence, asking for:
+ *  rx=1 tx=0 gives Pause+AsymDir advertisement, but we may end up
+ *            resolving to tx+rx pause or only rx pause depending on
+ *            the partners advertisement.
+ *  rx=0 tx=1 gives AsymDir only, which will only give tx pause if
+ *            the partners advertisement allows it.
+ *  rx=1 tx=1 gives Pause only, which will only allow tx+rx pause

+ *   a - EC timebase, sensor event
+ *   b - EC timebase, IRQ
+ *   c - AP timebase, IRQ
+ *   a' - what we want: sensor even in AP timebase
+ *
+ * While a and b are recorded at accurate times (due to the EC real time
+ * nature); c is pretty untrustworthy, even though it's recorded the
+ * first thing in ec_irq_handler(). There is a very good change we'll get
+ * added lantency due to:
+ *   other irqs
+ *   ddrfreq
+ *   cpuidle
+ *
+ * Normally a' = c - b + a, but if we do that naive math any jitter in c
+ * will get coupled in a', which we don't want. We want a function
+ * a' = cros_ec_sensor_ring_ts_filter(a) which will filter out outliers in c.
+ *
+ * Think of a graph of AP time(b) on the y axis vs EC time(c) on the x axis.
+ * The slope of the line won't be exactly 1, there will be some clock drift
+ * between the 2 chips for various reasons (mechanical stress, temperature,
+ * voltage). We need to extrapolate values for a future x, without trusting
+ * recent y values too much.
+ *
+ * We use a median filter for the slope, then another median filter for the
+ * y-intercept to calculate this function:
+ *   dx[n] = x[n-1] - x[n]
+ *   dy[n] = x[n-1] - x[n]
+ *   m[n] = dy[n] / dx[n]
+ *   median_m = median(m[n-k:n])
+ *   error[i] = y[n-i] - median_m * x[n-i]
+ *   median_error = median(error[:k])
+ *   predicted_y = median_m * x + median_error
+ *
+ * Implementation differences from above:
+ * - Redefined y to be actually c - b, this gives us a lot more precision
+ * to do the math. (c-b)/b variations are more obvious than c/b variations.
+ * - Since we don't have floating point, any operations involving slope are
+ * done using fixed point math (*M_PRECISION)
+ * - Since x and y grow with time, we keep zeroing the graph (relative to
+ * the last sample), this way math involving *x[n-i] will not overflow
+ * - EC timestamps are kept in us, it improves the slope calculation precision

+	  This driver adds support for the ACPI-WMI (Windows Management

+
+	  ACPI-WMI is a proprietary extension to ACPI to expose parts of the
+	  ACPI firmware to userspace - this is done through various vendor
+	  defined methods and data blocks in a PNP0C14 device, which are then
+	  made available for userspace to call.
+
+	  The implementation of this in Linux currently only exposes this to
+	  other kernel space drivers.
+
+	  This driver is a required dependency to build the firmware specific
+	  drivers needed on many machines, including Acer and HP laptops.

+ * This driver has been reverse-engineered by parsing the DSDT of the Surface 3
+ * and looking at the registers of the chips.
+ *
+ * The DSDT allowed to find out that:
+ * - the driver is required for the ACPI BAT0 device to communicate to the chip
+ *   through an operation region.
+ * - the various defines for the operation region functions to communicate with
+ *   this driver
+ * - the DSM 3f99e367-6220-4955-8b0f-06ef2ae79412 allows to trigger ACPI
+ *   events to BAT0 (the code is all available in the DSDT).
+ *
+ * Further findings regarding the 2 chips declared in the MSHW0011 are:
+ * - there are 2 chips declared:
+ *   . 0x22 seems to control the ADP1 line status (and probably the charger)
+ *   . 0x55 controls the battery directly
+ * - the battery chip uses a SMBus protocol (using plain SMBus allows non
+ *   destructive commands):
+ *   . the commands/registers used are in the range 0x00..0x7F
+ *   . if bit 8 (0x80) is set in the SMBus command, the returned value is the
+ *     same as when it is not set. There is a high chance this bit is the
+ *     read/write
+ *   . the various registers semantic as been deduced by observing the register
+ *     dumps.

+ * Cherry Trail SoC + TI PMIC,     DMI_BOARD_NAME: "827C" or "82F4"
+ *
+ * The variants with the AXP288 PMIC are all kinds of special:
+ *
+ * 1. All variants use a Type-C connector which the AXP288 does not support, so
+ * when using a Type-C charger it is not recognized. Unlike most AXP288 devices,
+ * this model actually has mostly working ACPI AC / Battery code, the ACPI code
+ * "solves" this by simply setting the input_current_limit to 3A.
+ * There are still some issues with the ACPI code, so we use this native driver,
+ * and to solve the charging not working (500mA is not enough) issue we hardcode
+ * the 3A input_current_limit like the ACPI code does.
+ *
+ * 2. If no charger is connected the machine boots with the vbus-path disabled.
+ * Normally this is done when a 5V boost converter is active to avoid the PMIC
+ * trying to charge from the 5V boost converter's output. This is done when
+ * an OTG host cable is inserted and the ID pin on the micro-B receptacle is
+ * pulled low and the ID pin has an ACPI event handler associated with it
+ * which re-enables the vbus-path when the ID pin is pulled high when the
+ * OTG host cable is removed. The Type-C connector has no ID pin, there is
+ * no ID pin handler and there appears to be no 5V boost converter, so we
+ * end up not charging because the vbus-path is disabled, until we unplug
+ * the charger which automatically clears the vbus-path disable bit and then
+ * on the second plug-in of the adapter we start charging. To solve the not
+ * charging on first charger plugin we unconditionally enable the vbus-path at
+ * probe on this model, which is safe since there is no 5V boost converter.

  * Description:
  *   This file is the core OMAP support for the generic, Linux
- *   PWM driver / controller, using the OMAP's dual-mode timers.
+ *   PWM driver / controller, using the OMAP's dual-mode timers
+ *   with a timer counter that goes up. When it overflows it gets
+ *   reloaded with the load value and the pwm output goes up.
+ *   When counter matches with match register, the output goes down.
+ *   Reference Manual: http://www.ti.com/lit/ug/spruh73q/spruh73q.pdf
+ *
+ * Limitations:
+ * - When PWM is stopped, timer counter gets stopped immediately. This
+ *   doesn't allow the current PWM period to complete and stops abruptly.
+ * - When PWM is running and changing both duty cycle and period,
+ *   we cannot prevent in software that the output might produce
+ *   a period with mixed settings. Especially when period/duty_cyle
+ *   is updated while the pwm pin is high, current pwm period/duty_cycle
+ *   can get updated as below based on the current timer counter:
+ *   	- period for current cycle =  current_period + new period
+ *   	- duty_cycle for current period = current period + new duty_cycle.
+ * - PWM OMAP DM timer cannot change the polarity when pwm is active. When
+ *   user requests a change in polarity when in active state:
+ *	- PWM is stopped abruptly(without completing the current cycle)
+ *	- Polarity is changed
+ *	- A fresh cycle is started.

-same for ffsWriteFile.
-
-All the calls to fs_sync() need to be looked at, particularly in the
-context of EXFAT_DELAYED_SYNC. Currently, if that's defined, we only
-flush to disk when sync() gets called.  We should be doing at least
-metadata flushes at appropriate times.
-
-ffsTruncateFile -  if (old_size <= new_size) {
-That doesn't look right. How did it ever work? Are they relying on lazy
-block allocation when actual writes happen? If nothing else, it never
-does the 'fid->size = new_size' and do the inode update....
-
-ffsSetAttr() is just dangling in the breeze, not wired up at all...
-
-Convert global mutexes to a per-superblock mutex.
-
-Right now, we load exactly one UTF-8 table. Check to see
-if that plays nice with different codepage and iocharset values
-for simultanous mounts of different devices
-
-exfat_rmdir() checks for -EBUSY but ffsRemoveDir() doesn't return it.
-In fact, there's a complete lack of -EBUSY testing anywhere.
-
-There's probably a few missing checks for -EEXIST
-
-check return codes of sync_dirty_buffer()
-
-Why is remove_file doing a num_entries++??
-
-Double check a lot of can't-happen parameter checks (for null pointers for
-things that have only one call site and can't pass a null, etc).
-
-All the DEBUG stuff can probably be tossed, including the ioctl(). Either
-that, or convert to a proper fault-injection system.
-
-exfat_remount does exactly one thing.  Fix to actually deal with remount
-options, particularly handling R/O correctly.  For that matter, allow
-R/O mounts in the first place.
-
-Figure out why the VFAT code used multi_sector_(read|write) but the
-exfat code doesn't use it. The difference matters on SSDs with wear leveling.
-
-exfat_fat_sync(), exfat_buf_sync(), and sync_alloc_bitmap()
-aren't called anyplace....
-
-Create helper function for exfat_set_entry_time() and exfat_set_entry_type()
-because it's sort of ugly to be calling the same functionn directly and
-other code calling through the fs_func struc ponters...
-
-clean up the remaining vol_type checks, which are of two types:
-some are ?: operators with magic numbers, and the rest are places
-where we're doing stuff with '.' and '..'.

-** HP CASCADE Architecture Driver for 100VG-AnyLan Network Adapters
-**
-** $Id: hp100.c,v 1.58 2001/09/24 18:03:01 perex Exp perex $
-**
-** Based on the HP100 driver written by Jaroslav Kysela <perex@jcu.cz>
-** Extended for new busmaster capable chipsets by
-** Siegfried "Frieder" Loeffler (dg1sek) <floeff@mathematik.uni-stuttgart.de>
-**
-** Maintained by: Jaroslav Kysela <perex@perex.cz>
-**
-** This driver has only been tested with
-** -- HP J2585B 10/100 Mbit/s PCI Busmaster
-** -- HP J2585A 10/100 Mbit/s PCI
-** -- HP J2970A 10 Mbit/s PCI Combo 10base-T/BNC
-** -- HP J2973A 10 Mbit/s PCI 10base-T
-** -- HP J2573  10/100 ISA
-** -- Compex ReadyLink ENET100-VG4  10/100 Mbit/s PCI / EISA
-** -- Compex FreedomLine 100/VG  10/100 Mbit/s ISA / EISA / PCI
-**
-** but it should also work with the other CASCADE based adapters.
-**
-** TODO:
-**       -  J2573 seems to hang sometimes when in shared memory mode.
-**       -  Mode for Priority TX
-**       -  Check PCI registers, performance might be improved?
-**       -  To reduce interrupt load in busmaster, one could switch off
-**          the interrupts that are used to refill the queues whenever the
-**          queues are filled up to more than a certain threshold.
-**       -  some updates for EISA version of card
-**
-**
-**
-** 1.57c -> 1.58
-**   - used indent to change coding-style
-**   - added KTI DP-200 EISA ID
-**   - ioremap is also used for low (<1MB) memory (multi-architecture support)
-**
-** 1.57b -> 1.57c - Arnaldo Carvalho de Melo <acme@conectiva.com.br>
-**   - release resources on failure in init_module
-**
-** 1.57 -> 1.57b - Jean II
-**   - fix spinlocks, SMP is now working !
-**
-** 1.56 -> 1.57
-**   - updates for new PCI interface for 2.1 kernels
-**
-** 1.55 -> 1.56
-**   - removed printk in misc. interrupt and update statistics to allow
-**     monitoring of card status
-**   - timing changes in xmit routines, relogin to 100VG hub added when
-**     driver does reset
-**   - included fix for Compex FreedomLine PCI adapter
-**
-** 1.54 -> 1.55
-**   - fixed bad initialization in init_module
-**   - added Compex FreedomLine adapter
-**   - some fixes in card initialization
-**
-** 1.53 -> 1.54
-**   - added hardware multicast filter support (doesn't work)
-**   - little changes in hp100_sense_lan routine
-**     - added support for Coax and AUI (J2970)
-**   - fix for multiple cards and hp100_mode parameter (insmod)
-**   - fix for shared IRQ
-**
-** 1.52 -> 1.53
-**   - fixed bug in multicast support

-Description:
-		This attribute, if available, is used to close or open the
-		bridge power down switch found on some converters.
-		In bridge applications, such as strain gauges and load cells,
-		the bridge itself consumes the majority of the current in the
-		system. To minimize the current consumption of the system,
-		the bridge can be disconnected (when it is not being used
-		using the bridge_switch_en attribute.

+	 *	This interrupt is asserted when the Non-Periodic TxFIFO is
+	 *	either half or completely empty, and there is space for at least

+	 *	at either HS or FS.
+	 * @otgint: OTG Interrupt (OTGInt)
+	 *	The core sets this bit to indicate an OTG protocol event. The

-	help
-	  UWB is a high-bandwidth, low-power, point-to-point radio
-	  technology using a wide spectrum (3.1-10.6GHz). It is
-	  optimized for in-room use (480Mbps at 2 meters, 110Mbps at
-	  10m). It serves as the transport layer for other protocols,
-	  such as Wireless USB (WUSB).
-
-	  The topology is peer to peer; however, higher level
-	  protocols (such as WUSB) might impose a master/slave
-	  relationship.
-
-	  Say Y here if your computer has UWB radio controllers (USB or PCI)
-	  based. You will need to enable the radio controllers
-	  below.  It is ok to select all of them, no harm done.
-
-	  For more help check the UWB and WUSB related files in
-	  <file:Documentation/usb/>.
-
-	  To compile the UWB stack as a module, choose M here.

-	  This driver enables the radio controller for HWA USB
-	  devices. HWA stands for Host Wire Adapter, and it is a UWB
-	  Radio Controller connected to your system via USB. Most of
-	  them come with a Wireless USB host controller also.

-
-          WHCI is a specification developed by Intel
-          (http://www.intel.com/technology/comms/wusb/whci.htm) much
-          in the spirit of USB's EHCI, but for UWB and Wireless USB
-          radio/host controllers connected via memory mapping (eg:
-          PCI). Most of these cards come also with a Wireless USB host
-          controller.

-         USB. It consists of a firmware uploader that will enable it

- * We might have to upload before or after a phy firmware (which might

- *
- * Because USB and PCI use common methods, we just make ops out of the
- * common operations (read, write, wait_init_done and cmd) and
- * implement them in usb.c and pci.c.

- *
- * i1480_{usb,pci}_probe()	  On enumerate/discovery
- *   i1480_fw_upload()
- *     i1480_pre_fw_upload()

- *
- * UMC (UWB Multi-interface Controller) capabilities (e.g., radio

- *
- * The radio controller is not strictly a UMC capability but it's

- *   [WHCI] Wireless Host Controller Interface Specification for

- *
- * How this works is kind of convoluted but simple. The whci.ko driver
- * loads when WHCI devices are detected. These WHCI devices expose
- * many devices in the same PCI function (they couldn't have reused
- * functions, no), so for each PCI function that exposes these many
- * devices, whci ceates a umc_dev [whci_probe() -> whci_add_cap()]
- * with umc_device_create() and adds it to the bus with
- * umc_device_register().
- *
- * umc_device_register() calls device_register() which will push the
- * bus management code to load your UMC driver's somehting_probe()
- * that you have registered for that capability code.
- *
- * Now when the WHCI device is removed, whci_remove() will go over
- * each umc_dev assigned to each of the PCI function's capabilities
- * and through whci_del_cap() call umc_device_unregister() each
- * created umc_dev. Of course, if you are bound to the device, your
- * driver's something_remove() will be called.

- * WUSB Wire Adapter: Radio Control Interface (WUSB[8])
- * Notification and Event Handling
- *
- * Copyright (C) 2005-2006 Intel Corporation
- * Inaky Perez-Gonzalez <inaky.perez-gonzalez@intel.com>
- *
- * The RC interface of the Host Wire Adapter (USB dongle) or WHCI PCI
- * card delivers a stream of notifications and events to the
- * notification end event endpoint or area. This code takes care of
- * getting a buffer with that data, breaking it up in separate
- * notifications and events and then deliver those.
- *
- * Events are answers to commands and they carry a context ID that
- * associates them to the command. Notifications are that,
- * notifications, they come out of the blue and have a context ID of
- * zero. Think of the context ID kind of like a handler. The
- * uwb_rc_neh_* code deals with managing context IDs.
- *
- * This is why you require a handle to operate on a UWB host. When you
- * open a handle a context ID is assigned to you.
- *
- * So, as it is done is:
- *
- * 1. Add an event handler [uwb_rc_neh_add()] (assigns a ctx id)
- * 2. Issue command [rc->cmd(rc, ...)]
- * 3. Arm the timeout timer [uwb_rc_neh_arm()]
- * 4, Release the reference to the neh [uwb_rc_neh_put()]
- * 5. Wait for the callback
- * 6. Command result (RCEB) is passed to the callback
- *
- * If (2) fails, you should remove the handle [uwb_rc_neh_rm()]
- * instead of arming the timer.
- *
- * Handles are for using in *serialized* code, single thread.
- *
- * When the notification/event comes, the IRQ handler/endpoint
- * callback passes the data read to uwb_rc_neh_grok() which will break
- * it up in a discrete series of events, look up who is listening for
- * them and execute the pertinent callbacks.
- *
- * If the reader detects an error while reading the data stream, call
- * uwb_rc_neh_error().
- *
- * CONSTRAINTS/ASSUMPTIONS:
- *
- * - Most notifications/events are small (less thank .5k), copying
- *   around is ok.
- *
- * - Notifications/events are ALWAYS smaller than PAGE_SIZE
- *
- * - Notifications/events always come in a single piece (ie: a buffer
- *   will always contain entire notifications/events).
- *
- * - we cannot know in advance how long each event is (because they
- *   lack a length field in their header--smart move by the standards
- *   body, btw). So we need a facility to get the event size given the
- *   header. This is what the EST code does (notif/Event Size
- *   Tables), check nest.c--as well, you can associate the size to
- *   the handle [w/ neh->extra_size()].
- *
- * - Most notifications/events are fixed size; only a few are variable
- *   size (NEST takes care of that).
- *
- * - Listeners of events expect them, so they usually provide a
- *   buffer, as they know the size. Listeners to notifications don't,
- *   so we allocate their buffers dynamically.

- * @rc:	      UWB Radio Controller
- * @buf:      Buffer with the stream of notifications/events
- * @buf_size: Amount of data in the buffer
- *
- * Note each notification/event starts always with a 'struct
- * uwb_rceb', so the minimum size if 4 bytes.
- *
- * The device may pass us events formatted differently than expected.
- * These are first filtered, potentially creating a new event in a new
- * memory location. If a new event is created by the filter it is also
- * freed here.
- *
- * For each notif/event, tries to guess the size looking at the EST
- * tables, then looks for a neh that is waiting for that event and if
- * found, copies the payload to the neh's buffer and calls it back. If
- * not, the data is ignored.
- *
- * Note that if we can't find a size description in the EST tables, we
- * still might find a size in the 'neh' handle in uwb_rc_neh_lookup().
- *
- * Assumptions:
- *
- *   @rc->neh_lock is NOT taken
- *
- * We keep track of various sizes here:
- * size:      contains the size of the buffer that is processed for the
- *            incoming event. this buffer may contain events that are not
- *            formatted as WHCI.
- * real_size: the actual space taken by this event in the buffer.
- *            We need to keep track of the real size of an event to be able to
- *            advance the buffer correctly.
- * event_size: the size of the event as expected by the core layer
- *            [OR] the size of the event after filtering. if the filtering
- *            created a new event in a new memory location then this is
- *            effectively the size of a new event buffer

-/**
- * UWB radio controller Event Size Entry (for creating entry tables)
- *
- * WUSB and WHCI define events and notifications, and they might have
- * fixed or variable size.
- *
- * Each event/notification has a size which is not necessarily known
- * in advance based on the event code. As well, vendor specific
- * events/notifications will have a size impossible to determine
- * unless we know about the device's specific details.
- *
- * It was way too smart of the spec writers not to think that it would
- * be impossible for a generic driver to skip over vendor specific
- * events/notifications if there are no LENGTH fields in the HEADER of
- * each message...the transaction size cannot be counted on as the
- * spec does not forbid to pack more than one event in a single
- * transaction.
- *
- * Thus, we guess sizes with tables (or for events, when you know the
- * size ahead of time you can use uwb_rc_neh_extra_size*()). We
- * register tables with the known events and their sizes, and then we
- * traverse those tables. For those with variable length, we provide a
- * way to lookup the size inside the event/notification's
- * payload. This allows device-specific event size tables to be
- * registered.
- *
- * @size:   Size of the payload
- *
- * @offset: if != 0, at offset @offset-1 starts a field with a length
- *          that has to be added to @size. The format of the field is
- *          given by @type.
- *
- * @type:   Type and length of the offset field. Most common is LE 16
- *          bits (that's why that is zero); others are there mostly to
- *          cover for bugs and weirdos.

- * Ultra Wide Band
- * Neighborhood Management Daemon
- *
- * Copyright (C) 2005-2006 Intel Corporation
- * Inaky Perez-Gonzalez <inaky.perez-gonzalez@intel.com>
- *
- * This daemon takes care of maintaing information that describes the
- * UWB neighborhood that the radios in this machine can see. It also
- * keeps a tab of which devices are visible, makes sure each HC sits
- * on a different channel to avoid interfering, etc.
- *
- * Different drivers (radio controller, device, any API in general)
- * communicate with this daemon through an event queue. Daemon wakes
- * up, takes a list of events and handles them one by one; handling
- * function is extracted from a table based on the event's type and
- * subtype. Events are freed only if the handling function says so.
- *
- *   . Lock protecting the event list has to be an spinlock and locked
- *     with IRQSAVE because it might be called from an interrupt
- *     context (ie: when events arrive and the notification drops
- *     down from the ISR).
- *
- *   . UWB radio controller drivers queue events to the daemon using
- *     uwbd_event_queue(). They just get the event, chew it to make it
- *     look like UWBD likes it and pass it in a buffer allocated with
- *     uwb_event_alloc().
- *
- * EVENTS
- *
- * Events have a type, a subtype, a length, some other stuff and the
- * data blob, which depends on the event. The header is 'struct
- * uwb_event'; for payloads, see 'struct uwbd_evt_*'.
- *
- * EVENT HANDLER TABLES
- *
- * To find a handling function for an event, the type is used to index
- * a subtype-table in the type-table. The subtype-table is indexed
- * with the subtype to get the function that handles the event. Start
- * with the main type-table 'uwbd_evt_type_handler'.
- *
- * DEVICES
- *
- * Devices are created when a bunch of beacons have been received and
- * it is stablished that the device has stable radio presence. CREATED
- * only, not configured. Devices are ONLY configured when an
- * Application-Specific IE Probe is receieved, in which the device
- * declares which Protocol ID it groks. Then the device is CONFIGURED
- * (and the driver->probe() stuff of the device model is invoked).
- *
- * Devices are considered disconnected when a certain number of
- * beacons are not received in an amount of time.
- *
- * Handler functions are called normally uwbd_evt_handle_*().

-** Functions to modify the state variables;
-**	set_suspend_state
-**	set_resume_state
-**
-** There are more state variables than we might like, so ensure they remain in
-** step.  Suspend and resume state are maintained separately, since most of
-** these state machines can operate independently.  However, there are a few
-** states where state transitions in one state machine cause a reset to the
-** other state machine.  In addition, there are some completion events which
-** need to occur on state machine reset and end-state(s), so these are also
-** dealt with in these functions.
-**
-** In all states we set the state variable according to the input, but in some
-** cases we perform additional steps outlined below;
-**
-** VC_SUSPEND_IDLE - Initialise the suspend completion at the same time.
-**			The suspend completion is completed after any suspend
-**			attempt.  When we reset the state machine we also reset
-**			the completion.  This reset occurs when videocore is
-**			resumed, and also if we initiate suspend after a suspend
-**			failure.
-**
-** VC_SUSPEND_IN_PROGRESS - This state is considered the point of no return for
-**			suspend - ie from this point on we must try to suspend
-**			before resuming can occur.  We therefore also reset the
-**			resume state machine to VC_RESUME_IDLE in this state.
-**
-** VC_SUSPEND_SUSPENDED - Suspend has completed successfully. Also call
-**			complete_all on the suspend completion to notify
-**			anything waiting for suspend to happen.
-**
-** VC_SUSPEND_REJECTED - Videocore rejected suspend. Videocore will also
-**			initiate resume, so no need to alter resume state.
-**			We call complete_all on the suspend completion to notify
-**			of suspend rejection.
-**
-** VC_SUSPEND_FAILED - We failed to initiate videocore suspend.  We notify the
-**			suspend completion and reset the resume state machine.
-**
-** VC_RESUME_IDLE - Initialise the resume completion at the same time.  The
-**			resume completion is in it's 'done' state whenever
-**			videcore is running.  Therefore, the VC_RESUME_IDLE
-**			state implies that videocore is suspended.
-**			Hence, any thread which needs to wait until videocore is
-**			running can wait on this completion - it will only block
-**			if videocore is suspended.
-**
-** VC_RESUME_RESUMED - Resume has completed successfully.  Videocore is running.
-**			Call complete_all on the resume completion to unblock
-**			any threads waiting for resume.	 Also reset the suspend
-**			state machine to it's idle state.
-**
-** VC_RESUME_FAILED - Currently unused - no mechanism to fail resume exists.

-Command for manipulating the pairing/authentication credentials of a
-Wireless USB device that supports wired-mode Cable-Based-Association.
-
-Works in conjunction with the wusb-cba.ko driver from http://linuxuwb.org.
-
-
-DEVICE
-
- sysfs path to the device to authenticate; for example, both this
- guys are the same:
-
- /sys/devices/pci0000:00/0000:00:1d.7/usb1/1-4/1-4.4/1-4.4:1.1
- /sys/bus/usb/drivers/wusb-cbaf/1-4.4:1.1
-
-COMMAND/ARGS are
-
- start
-
-   Start a WUSB host controller (by setting up a CHID)
-
- set-chid DEVICE HOST-CHID HOST-BANDGROUP HOST-NAME
-
-   Sets host information in the device; after this you can call the
-   get-cdid to see how does this device report itself to us.
-
- get-cdid DEVICE
-
-   Get the device ID associated to the HOST-CHID we sent with
-   'set-chid'. We might not know about it.
-
- set-cc DEVICE
-
-   If we allow the device to connect, set a random new CDID and CK
-   (connection key). Device saves them for the next time it wants to
-   connect wireless. We save them for that next time also so we can
-   authenticate the device (when we see the CDID he uses to id
-   itself) and the CK to crypto talk to it.
-
-CHID is always 16 hex bytes in 'XX YY ZZ...' form
-BANDGROUP is almost always 0001
-
-Examples:
-
-  You can default most arguments to '' to get a sane value:
-
-  $ $progname set-chid '' '' '' "My host name"
-
-  A full sequence:
-
-  $ $progname set-chid '' '' '' "My host name"
-  $ $progname get-cdid ''

-Introduction
-============
-
-UWB is a wide-band communication protocol that is to serve also as the
-low-level protocol for others (much like TCP sits on IP). Currently
-these others are Wireless USB and TCP/IP, but seems Bluetooth and
-Firewire/1394 are coming along.
-
-UWB uses a band from roughly 3 to 10 GHz, transmitting at a max of
-~-41dB (or 0.074 uW/MHz--geography specific data is still being
-negotiated w/ regulators, so watch for changes). That band is divided in
-a bunch of ~1.5 GHz wide channels (or band groups) composed of three
-subbands/subchannels (528 MHz each). Each channel is independent of each
-other, so you could consider them different "busses". Initially this
-driver considers them all a single one.
-
-Radio time is divided in 65536 us long /superframes/, each one divided
-in 256 256us long /MASs/ (Media Allocation Slots), which are the basic
-time/media allocation units for transferring data. At the beginning of
-each superframe there is a Beacon Period (BP), where every device
-transmit its beacon on a single MAS. The length of the BP depends on how
-many devices are present and the length of their beacons.
-
-Devices have a MAC (fixed, 48 bit address) and a device (changeable, 16
-bit address) and send periodic beacons to advertise themselves and pass
-info on what they are and do. They advertise their capabilities and a
-bunch of other stuff.
-
-The different logical parts of this driver are:
-
-    *
-
-      *UWB*: the Ultra-Wide-Band stack -- manages the radio and
-      associated spectrum to allow for devices sharing it. Allows to
-      control bandwidth assignment, beaconing, scanning, etc
-
-    *
-
-      *WUSB*: the layer that sits on top of UWB to provide Wireless USB.
-      The Wireless USB spec defines means to control a UWB radio and to
-      do the actual WUSB.
-
-
-HWA: Host Wire adapters, your Wireless USB dongle
--------------------------------------------------
-
-WUSB also defines a device called a Host Wire Adaptor (HWA), which in
-mere terms is a USB dongle that enables your PC to have UWB and Wireless
-USB. The Wireless USB Host Controller in a HWA looks to the host like a
-[Wireless] USB controller connected via USB (!)
-
-The HWA itself is broken in two or three main interfaces:
-
-    *
-
-      *RC*: Radio control -- this implements an interface to the
-      Ultra-Wide-Band radio controller. The driver for this implements a
-      USB-based UWB Radio Controller to the UWB stack.
-
-    *
-
-      *HC*: the wireless USB host controller. It looks like a USB host
-      whose root port is the radio and the WUSB devices connect to it.
-      To the system it looks like a separate USB host. The driver (will)
-      implement a USB host controller (similar to UHCI, OHCI or EHCI)
-      for which the root hub is the radio...To reiterate: it is a USB
-      controller that is connected via USB instead of PCI.
-
-    *
-
-      *WINET*: some HW provide a WiNET interface (IP over UWB). This
-      package provides a driver for it (it looks like a network
-      interface, winetX). The driver detects when there is a link up for
-      their type and kick into gear.
-
-
-DWA: Device Wired Adaptor, a Wireless USB hub for wired devices
----------------------------------------------------------------
-
-These are the complement to HWAs. They are a USB host for connecting
-wired devices, but it is connected to your PC connected via Wireless
-USB. To the system it looks like yet another USB host. To the untrained
-eye, it looks like a hub that connects upstream wirelessly.
-
-We still offer no support for this; however, it should share a lot of
-code with the HWA-RC driver; there is a bunch of factorization work that
-has been done to support that in upcoming releases.
-
-
-WHCI: Wireless Host Controller Interface, the PCI WUSB host adapter
--------------------------------------------------------------------
-
-This is your usual PCI device that implements WHCI. Similar in concept
-to EHCI, it allows your wireless USB devices (including DWAs) to connect
-to your host via a PCI interface. As in the case of the HWA, it has a
-Radio Control interface and the WUSB Host Controller interface per se.
-
-There is still no driver support for this, but will be in upcoming
-releases.
-
-
-The UWB stack
-=============
-
-The main mission of the UWB stack is to keep a tally of which devices
-are in radio proximity to allow drivers to connect to them. As well, it
-provides an API for controlling the local radio controllers (RCs from
-now on), such as to start/stop beaconing, scan, allocate bandwidth, etc.
-
-
-Devices and hosts: the basic structure
---------------------------------------
-
-The main building block here is the UWB device (struct uwb_dev). For
-each device that pops up in radio presence (ie: the UWB host receives a
-beacon from it) you get a struct uwb_dev that will show up in
-/sys/bus/uwb/devices.
-
-For each RC that is detected, a new struct uwb_rc and struct uwb_dev are
-created. An entry is also created in /sys/class/uwb_rc for each RC.
-
-Each RC driver is implemented by a separate driver that plugs into the
-interface that the UWB stack provides through a struct uwb_rc_ops. The
-spec creators have been nice enough to make the message format the same
-for HWA and WHCI RCs, so the driver is really a very thin transport that
-moves the requests from the UWB API to the device [/uwb_rc_ops->cmd()/]
-and sends the replies and notifications back to the API
-[/uwb_rc_neh_grok()/]. Notifications are handled to the UWB daemon, that
-is chartered, among other things, to keep the tab of how the UWB radio
-neighborhood looks, creating and destroying devices as they show up or
-disappear.
-
-Command execution is very simple: a command block is sent and a event
-block or reply is expected back. For sending/receiving command/events, a
-handle called /neh/ (Notification/Event Handle) is opened with
-/uwb_rc_neh_open()/.
-
-The HWA-RC (USB dongle) driver (drivers/uwb/hwa-rc.c) does this job for
-the USB connected HWA. Eventually, drivers/whci-rc.c will do the same
-for the PCI connected WHCI controller.
-
-
-Host Controller life cycle
---------------------------
-
-So let's say we connect a dongle to the system: it is detected and
-firmware uploaded if needed [for Intel's i1480
-/drivers/uwb/ptc/usb.c:ptc_usb_probe()/] and then it is reenumerated.
-Now we have a real HWA device connected and
-/drivers/uwb/hwa-rc.c:hwarc_probe()/ picks it up, that will set up the
-Wire-Adaptor environment and then suck it into the UWB stack's vision of
-the world [/drivers/uwb/lc-rc.c:uwb_rc_add()/].
-
-    *
-
-      [*] The stack should put a new RC to scan for devices
-      [/uwb_rc_scan()/] so it finds what's available around and tries to
-      connect to them, but this is policy stuff and should be driven
-      from user space. As of now, the operator is expected to do it
-      manually; see the release notes for documentation on the procedure.
-
-When a dongle is disconnected, /drivers/uwb/hwa-rc.c:hwarc_disconnect()/
-takes time of tearing everything down safely (or not...).
-
-
-On the air: beacons and enumerating the radio neighborhood
-----------------------------------------------------------
-
-So assuming we have devices and we have agreed for a channel to connect
-on (let's say 9), we put the new RC to beacon:
-
-    *
-
-            $ echo 9 0 > /sys/class/uwb_rc/uwb0/beacon
-
-Now it is visible. If there were other devices in the same radio channel
-and beacon group (that's what the zero is for), the dongle's radio
-control interface will send beacon notifications on its
-notification/event endpoint (NEEP). The beacon notifications are part of
-the event stream that is funneled into the API with
-/drivers/uwb/neh.c:uwb_rc_neh_grok()/ and delivered to the UWBD, the UWB
-daemon through a notification list.
-
-UWBD wakes up and scans the event list; finds a beacon and adds it to
-the BEACON CACHE (/uwb_beca/). If he receives a number of beacons from
-the same device, he considers it to be 'onair' and creates a new device
-[/drivers/uwb/lc-dev.c:uwbd_dev_onair()/]. Similarly, when no beacons
-are received in some time, the device is considered gone and wiped out
-[uwbd calls periodically /uwb/beacon.c:uwb_beca_purge()/ that will purge
-the beacon cache of dead devices].
-
-
-Device lists
-------------
-
-All UWB devices are kept in the list of the struct bus_type uwb_bus_type.
-
-
-Bandwidth allocation
---------------------
-
-The UWB stack maintains a local copy of DRP availability through
-processing of incoming *DRP Availability Change* notifications. This
-local copy is currently used to present the current bandwidth
-availability to the user through the sysfs file
-/sys/class/uwb_rc/uwbx/bw_avail. In the future the bandwidth
-availability information will be used by the bandwidth reservation
-routines.
-
-The bandwidth reservation routines are in progress and are thus not
-present in the current release. When completed they will enable a user
-to initiate DRP reservation requests through interaction with sysfs. DRP
-reservation requests from remote UWB devices will also be handled. The
-bandwidth management done by the UWB stack will include callbacks to the
-higher layers will enable the higher layers to use the reservations upon
-completion. [Note: The bandwidth reservation work is in progress and
-subject to change.]
-
-
-Wireless USB Host Controller drivers
-====================================
-
-*WARNING* This section needs a lot of work!
-
-As explained above, there are three different types of HCs in the WUSB
-world: HWA-HC, DWA-HC and WHCI-HC.
-
-HWA-HC and DWA-HC share that they are Wire-Adapters (USB or WUSB
-connected controllers), and their transfer management system is almost
-identical. So is their notification delivery system.
-
-HWA-HC and WHCI-HC share that they are both WUSB host controllers, so
-they have to deal with WUSB device life cycle and maintenance, wireless
-root-hub
-
-HWA exposes a Host Controller interface (HWA-HC 0xe0/02/02). This has
-three endpoints (Notifications, Data Transfer In and Data Transfer
-Out--known as NEP, DTI and DTO in the code).
-
-We reserve UWB bandwidth for our Wireless USB Cluster, create a Cluster
-ID and tell the HC to use all that. Then we start it. This means the HC
-starts sending MMCs.
-
-    *
-
-      The MMCs are blocks of data defined somewhere in the WUSB1.0 spec
-      that define a stream in the UWB channel time allocated for sending
-      WUSB IEs (host to device commands/notifications) and Device
-      Notifications (device initiated to host). Each host defines a
-      unique Wireless USB cluster through MMCs. Devices can connect to a
-      single cluster at the time. The IEs are Information Elements, and
-      among them are the bandwidth allocations that tell each device
-      when can they transmit or receive.
-
-Now it all depends on external stimuli.
-
-New device connection
----------------------
-
-A new device pops up, it scans the radio looking for MMCs that give out
-the existence of Wireless USB channels. Once one (or more) are found,
-selects which one to connect to. Sends a /DN_Connect/ (device
-notification connect) during the DNTS (Device Notification Time
-Slot--announced in the MMCs
-
-HC picks the /DN_Connect/ out (nep module sends to notif.c for delivery
-into /devconnect/). This process starts the authentication process for
-the device. First we allocate a /fake port/ and assign an
-unauthenticated address (128 to 255--what we really do is
-0x80 | fake_port_idx). We fiddle with the fake port status and /hub_wq/
-sees a new connection, so he moves on to enable the fake port with a reset.
-
-So now we are in the reset path -- we know we have a non-yet enumerated
-device with an unauthorized address; we ask user space to authenticate
-(FIXME: not yet done, similar to bluetooth pairing), then we do the key
-exchange (FIXME: not yet done) and issue a /set address 0/ to bring the
-device to the default state. Device is authenticated.
-
-From here, the USB stack takes control through the usb_hcd ops. hub_wq
-has seen the port status changes, as we have been toggling them. It will
-start enumerating and doing transfers through usb_hcd->urb_enqueue() to
-read descriptors and move our data.
-
-Device life cycle and keep alives
----------------------------------
-
-Every time there is a successful transfer to/from a device, we update a
-per-device activity timestamp. If not, every now and then we check and
-if the activity timestamp gets old, we ping the device by sending it a
-Keep Alive IE; it responds with a /DN_Alive/ pong during the DNTS (this
-arrives to us as a notification through
-devconnect.c:wusb_handle_dn_alive(). If a device times out, we
-disconnect it from the system (cleaning up internal information and
-toggling the bits in the fake hub port, which kicks hub_wq into removing
-the rest of the stuff).
-
-This is done through devconnect:__wusb_check_devs(), which will scan the
-device list looking for whom needs refreshing.
-
-If the device wants to disconnect, it will either die (ugly) or send a
-/DN_Disconnect/ that will prompt a disconnection from the system.
-
-Sending and receiving data
---------------------------
-
-Data is sent and received through /Remote Pipes/ (rpipes). An rpipe is
-/aimed/ at an endpoint in a WUSB device. This is the same for HWAs and
-DWAs.
-
-Each HC has a number of rpipes and buffers that can be assigned to them;
-when doing a data transfer (xfer), first the rpipe has to be aimed and
-prepared (buffers assigned), then we can start queueing requests for
-data in or out.
-
-Data buffers have to be segmented out before sending--so we send first a
-header (segment request) and then if there is any data, a data buffer
-immediately after to the DTI interface (yep, even the request). If our
-buffer is bigger than the max segment size, then we just do multiple
-requests.
-
-[This sucks, because doing USB scatter gatter in Linux is resource
-intensive, if any...not that the current approach is not. It just has to
-be cleaned up a lot :)].
-
-If reading, we don't send data buffers, just the segment headers saying
-we want to read segments.
-
-When the xfer is executed, we receive a notification that says data is
-ready in the DTI endpoint (handled through
-xfer.c:wa_handle_notif_xfer()). In there we read from the DTI endpoint a
-descriptor that gives us the status of the transfer, its identification
-(given when we issued it) and the segment number. If it was a data read,
-we issue another URB to read into the destination buffer the chunk of
-data coming out of the remote endpoint. Done, wait for the next guy. The
-callbacks for the URBs issued from here are the ones that will declare
-the xfer complete at some point and call its callback.
-
-Seems simple, but the implementation is not trivial.
-
-    *
-
-      *WARNING* Old!!
-
-The main xfer descriptor, wa_xfer (equivalent to a URB) contains an
-array of segments, tallys on segments and buffers and callback
-information. Buried in there is a lot of URBs for executing the segments
-and buffer transfers.
-
-For OUT xfers, there is an array of segments, one URB for each, another
-one of buffer URB. When submitting, we submit URBs for segment request
-1, buffer 1, segment 2, buffer 2...etc. Then we wait on the DTI for xfer
-result data; when all the segments are complete, we call the callback to
-finalize the transfer.
-
-For IN xfers, we only issue URBs for the segments we want to read and
-then wait for the xfer result data.
-
-URB mapping into xfers
-^^^^^^^^^^^^^^^^^^^^^^
-
-This is done by hwahc_op_urb_[en|de]queue(). In enqueue() we aim an
-rpipe to the endpoint where we have to transmit, create a transfer
-context (wa_xfer) and submit it. When the xfer is done, our callback is
-called and we assign the status bits and release the xfer resources.
-
-In dequeue() we are basically cancelling/aborting the transfer. We issue
-a xfer abort request to the HC, cancel all the URBs we had submitted
-and not yet done and when all that is done, the xfer callback will be
-called--this will call the URB callback.

- * WUSB devices have to be paired (associated in WUSB lingo) so
- * that they can connect to the system.
- *
- * One way of pairing is using CBA-Cable Based Association. First
- * time you plug the device with a cable, association is done between
- * host and device and subsequent times, you can connect wirelessly
- * without having to associate again. That's the idea.
- *
- * This driver does nothing Earth shattering. It just provides an
- * interface to chat with the wire-connected device so we can get a
- * CDID (device ID) that might have been previously associated to a
- * CHID (host ID) and to set up a new <CHID,CDID,CK> triplet
- * (connection context), with the CK being the secret, or connection
- * key. This is the pairing data.
- *
- * When a device with the CBA capability connects, the probe routine
- * just creates a bunch of sysfs files that a user space enumeration
- * manager uses to allow it to connect wirelessly to the system or not.
- *
- * The process goes like this:
- *
- * 1. Device plugs, cbaf is loaded, notifications happen.
- *
- * 2. The connection manager (CM) sees a device with CBAF capability
- *    (the wusb_chid etc. files in /sys/devices/blah/OURDEVICE).
- *
- * 3. The CM writes the host name, supported band groups, and the CHID
- *    (host ID) into the wusb_host_name, wusb_host_band_groups and
- *    wusb_chid files. These get sent to the device and the CDID (if
- *    any) for this host is requested.
- *
- * 4. The CM can verify that the device's supported band groups
- *    (wusb_device_band_groups) are compatible with the host.
- *
- * 5. The CM reads the wusb_cdid file.
- *
- * 6. The CM looks up its database
- *
- * 6.1 If it has a matching CHID,CDID entry, the device has been
- *     authorized before (paired) and nothing further needs to be
- *     done.
- *
- * 6.2 If the CDID is zero (or the CM doesn't find a matching CDID in
- *     its database), the device is assumed to be not known.  The CM
- *     may associate the host with device by: writing a randomly
- *     generated CDID to wusb_cdid and then a random CK to wusb_ck
- *     (this uploads the new CC to the device).
- *
- *     CMD may choose to prompt the user before associating with a new
- *     device.
- *
- * 7. Device is unplugged.
- *
- * When the device tries to connect wirelessly, it will present its
- * CDID to the WUSB host controller.  The CM will query the
- * database. If the CHID/CDID pair found, it will (with a 4-way
- * handshake) challenge the device to demonstrate it has the CK secret
- * key (from our database) without actually exchanging it. Once
- * satisfied, crypto keys are derived from the CK, the device is
- * connected and all communication is encrypted.

- * @b: data stream to be processed
- *
- * @blen: size of b...
- *
- * Still not very clear how this is done, but looks like this: we

- * @key. We bytewise xor B0 with B1 (1) and AES-crypt that. Then we
- * take the payload and divide it in blocks (16 bytes), xor them with
- * the previous crypto result (16 bytes) and crypt it, repeat the next
- * block with the output of the previous one, rinse wash. So we use
- * the CBC-MAC(AES) shash, that does precisely that. The IV (Initial
- * Vector) is 16 bytes and is set to zero, so
- *
- * (1) Created as 6.5 says, again, using as l(a) 'Blen + 14', and
- *     using the 14 bytes of @a to fill up
- *     b1.{mac_header,e0,security_reserved,padding}.
- *
- * NOTE: The definition of l(a) in WUSB1.0[6.5] vs the definition of
- *       l(m) is orthogonal, they bear no relationship, so it is not
- *       in conflict with the parameter's relation that
- *       WUSB1.0[6.4.2]) defines.
- *
- * NOTE: WUSB1.0[A.1]: Host Nonce is missing a nibble? (1e); fixed in
- *       first errata released on 2005/07.
- *
- * NOTE: we need to clean IV to zero at each invocation to make sure
- *       we start with a fresh empty Initial Vector, so that the CBC
- *       works ok.
- *
- * NOTE: blen is not aligned to a block size, we'll pad zeros, that's
- *       what sg[4] is for. Maybe there is a smarter way to do this.

- *
- *
- * WUSB1.0[7.1, 7.5.1, ]
- *
- * WUSB device connection is kind of messy. Some background:
- *
- *     When a device wants to connect it scans the UWB radio channels
- *     looking for a WUSB Channel; a WUSB channel is defined by MMCs
- *     (Micro Managed Commands or something like that) [see
- *     Design-overview for more on this] .
- *
- * So, device scans the radio, finds MMCs and thus a host and checks
- * when the next DNTS is. It sends a Device Notification Connect
- * (DN_Connect); the host picks it up (through nep.c and notif.c, ends
- * up in wusb_devconnect_ack(), which creates a wusb_dev structure in
- * wusbhc->port[port_number].wusb_dev), assigns an unauth address
- * to the device (this means from 0x80 to 0xfe) and sends, in the MMC
- * a Connect Ack Information Element (ConnAck IE).
- *
- * So now the device now has a WUSB address. From now on, we use
- * that to talk to it in the RPipes.
- *
- * ASSUMPTIONS:
- *
- *  - We use the the as device address the port number where it is
- *    connected (port 0 doesn't exist). For unauth, it is 128 + that.
- *
- * ROADMAP:
- *
- *   This file contains the logic for doing that--entry points:
- *
- *   wusb_devconnect_ack()      Ack a device until _acked() called.
- *                              Called by notif.c:wusb_handle_dn_connect()
- *                              when a DN_Connect is received.
- *
- *     wusb_devconnect_acked()  Ack done, release resources.
- *
- *   wusb_handle_dn_alive()     Called by notif.c:wusb_handle_dn()
- *                              for processing a DN_Alive pong from a device.
- *
- *   wusb_handle_dn_disconnect()Called by notif.c:wusb_handle_dn() to
- *                              process a disconnect request from a
- *                              device.
- *
- *   __wusb_dev_disable()       Called by rh.c:wusbhc_rh_clear_port_feat() when
- *                              disabling a port.
- *
- *   wusb_devconnect_create()   Called when creating the host by
- *                              lc.c:wusbhc_create().
- *
- *   wusb_devconnect_destroy()  Cleanup called removing the host. Called
- *                              by lc.c:wusbhc_destroy().
- *
- *   Each Wireless USB host maintains a list of DN_Connect requests
- *   (actually we maintain a list of pending Connect Acks, the
- *   wusbhc->ca_list).
- *
- * LIFE CYCLE OF port->wusb_dev
- *
- *   Before the @wusbhc structure put()s the reference it owns for
- *   port->wusb_dev [and clean the wusb_dev pointer], it needs to
- *   lock @wusbhc->mutex.

- * We fake a root hub that has fake ports (as many as simultaneous
- * devices the Wireless USB Host Controller can deal with). For each
- * port we keep an state in @wusbhc->port[index] identical to the one
- * specified in the USB2.0[ch11] spec and some extra device
- * information that complements the one in 'struct usb_device' (as
- * this lacs a hcpriv pointer).
- *
- * Note this is common to WHCI and HWA host controllers.
- *
- * Through here we enable most of the state changes that the USB stack
- * will use to connect or disconnect devices. We need to do some
- * forced adaptation of Wireless USB device states vs. wired:
- *
- *        USB:                 WUSB:
- *
- * Port   Powered-off          port slot n/a
- *        Powered-on           port slot available
- *        Disconnected         port slot available
- *        Connected            port slot assigned device
- *        		       device sent DN_Connect
- *                             device was authenticated
- *        Enabled              device is authenticated, transitioned
- *                             from unauth -> auth -> default address
- *                             -> enabled
- *        Reset                disconnect
- *        Disable              disconnect
- *
- * This maps the standard USB port states with the WUSB device states
- * so we can fake ports without having to modify the USB stack.
- *
- * FIXME: this process will change in the future
- *
- *
- * ENTRY POINTS
- *
- * Our entry points into here are, as in hcd.c, the USB stack root hub

- * HWA Host Controller Driver
- * Wire Adapter Control/Data Streaming Iface (WUSB1.0[8])
- *
- * Copyright (C) 2005-2006 Intel Corporation
- * Inaky Perez-Gonzalez <inaky.perez-gonzalez@intel.com>
- *
- * This driver implements a USB Host Controller (struct usb_hcd) for a
- * Wireless USB Host Controller based on the Wireless USB 1.0
- * Host-Wire-Adapter specification (in layman terms, a USB-dongle that
- * implements a Wireless USB host).
- *
- * Check out the Design-overview.txt file in the source documentation
- * for other details on the implementation.
- *
- * Main blocks:
- *
- *  driver     glue with the driver API, workqueue daemon
- *
- *  lc         RC instance life cycle management (create, destroy...)
- *
- *  hcd        glue with the USB API Host Controller Interface API.
- *
- *  nep        Notification EndPoint management: collect notifications
- *             and queue them with the workqueue daemon.
- *
- *             Handle notifications as coming from the NEP. Sends them
- *             off others to their respective modules (eg: connect,
- *             disconnect and reset go to devconnect).
- *
- *  rpipe      Remote Pipe management; rpipe is what we use to write
- *             to an endpoint on a WUSB device that is connected to a
- *             HWA RC.
- *
- *  xfer       Transfer management -- this is all the code that gets a
- *             buffer and pushes it to a device (or viceversa). *
- *
- * Some day a lot of this code will be shared between this driver and
- * the drivers for DWA (xfer, rpipe).
- *
- * All starts at driver.c:hwahc_probe(), when one of this guys is
- * connected. hwahc_disconnect() stops it.
- *
- * During operation, the main driver is devices connecting or
- * disconnecting. They cause the HWA RC to send notifications into
- * nep.c:hwahc_nep_cb() that will dispatch them to
- * notif.c:wa_notif_dispatch(). From there they will fan to cause
- * device connects, disconnects, etc.
- *
- * Note much of the activity is difficult to follow. For example a
- * device connect goes to devconnect, which will cause the "fake" root
- * hub port to show a connect and stop there. Then hub_wq will notice
- * and call into the rh.c:hwahc_rc_port_reset() code to authenticate
- * the device (and this might require user intervention) and enable
- * the port.
- *
- * We also have a timer workqueue going from devconnect.c that
- * schedules in hwahc_devconnect_create().
- *
- * The rest of the traffic is in the usual entry points of a USB HCD,
- * which are hooked up in driver.c:hwahc_rc_driver, and defined in
- * hcd.c.

- * Inaky Perez-Gonzalez <inaky.perez-gonzalez@intel.com>
- *
- * This part takes care of getting the notification from the hw
- * only and dispatching through wusbwad into
- * wa_notif_dispatch. Handling is done there.
- *
- * WA notifications are limited in size; most of them are three or
- * four bytes long, and the longest is the HWA Device Notification,
- * which would not exceed 38 bytes (DNs are limited in payload to 32
- * bytes plus 3 bytes header (WUSB1.0[7.6p2]), plus 3 bytes HWA
- * header (WUSB1.0[8.5.4.2]).
- *
- * It is not clear if more than one Device Notification can be packed
- * in a HWA Notification, I assume no because of the wording in
- * WUSB1.0[8.5.4.2]. In any case, the bigger any notification could
- * get is 256 bytes (as the bLength field is a byte).
- *
- * So what we do is we have this buffer and read into it; when a
- * notification arrives we schedule work to a specific, single thread
- * workqueue (so notifications are serialized) and copy the
- * notification data. After scheduling the work, we rearm the read from
- * the notification endpoint.
- *
- * Entry points here are:
- *
- * wa_nep_[create|destroy]()   To initialize/release this subsystem
- *
- * wa_nep_cb()                 Callback for the notification
- *                                endpoint; when data is ready, this
- *                                does the dispatching.

- * RPIPE
- *
- *   Targeted at different downstream endpoints
- *
- *   Descriptor: use to config the remote pipe.
- *
- *   The number of blocks could be dynamic (wBlocks in descriptor is
- *   0)--need to schedule them then.
- *
- * Each bit in wa->rpipe_bm represents if an rpipe is being used or
- * not. Rpipes are represented with a 'struct wa_rpipe' that is
- * attached to the hcpriv member of a 'struct usb_host_endpoint'.
- *
- * When you need to xfer data to an endpoint, you get an rpipe for it
- * with wa_ep_rpipe_get(), which gives you a reference to the rpipe
- * and keeps a single one (the first one) with the endpoint. When you
- * are done transferring, you drop that reference. At the end the
- * rpipe is always allocated and bound to the endpoint. There it might
- * be recycled when not used.
- *
- * Addresses:
- *
- *  We use a 1:1 mapping mechanism between port address (0 based
- *  index, actually) and the address. The USB stack knows about this.
- *
- *  USB Stack port number    4 (1 based)
- *  WUSB code port index     3 (0 based)
- *  USB Address             5 (2 based -- 0 is for default, 1 for root hub)
- *
- *  Now, because we don't use the concept as default address exactly
- *  like the (wired) USB code does, we need to kind of skip it. So we
- *  never take addresses from the urb->pipe, but from the
- *  urb->dev->devnum, to make sure that we always have the right
- *  destination address.

- * How transfers work: get a buffer, break it up in segments (segment
- * size is a multiple of the maxpacket size). For each segment issue a
- * segment request (struct wa_xfer_*), then send the data buffer if
- * out or nothing if in (all over the DTO endpoint).
- *
- * For each submitted segment request, a notification will come over
- * the NEP endpoint and a transfer result (struct xfer_result) will
- * arrive in the DTI URB. Read it, get the xfer ID, see if there is
- * data coming (inbound transfer), schedule a read and handle it.
- *
- * Sounds simple, it is a pain to implement.

- *
- *   FIXME
- *
- * THIS CODE IS DISGUSTING
- *
- *   Warned you are; it's my second try and still not happy with it.
- *
- * NOTES:
- *
- *   - No iso
- *
- *   - Supports DMA xfers, control, bulk and maybe interrupt
- *
- *   - Does not recycle unused rpipes
- *
- *     An rpipe is assigned to an endpoint the first time it is used,
- *     and then it's there, assigned, until the endpoint is disabled
- *     (destroyed [{h,d}wahc_op_ep_disable()]. The assignment of the
- *     rpipe to the endpoint is done under the wa->rpipe_sem semaphore
- *     (should be a mutex).
- *
- *     Two methods it could be done:
- *
- *     (a) set up a timer every time an rpipe's use count drops to 1
- *         (which means unused) or when a transfer ends. Reset the
- *         timer when a xfer is queued. If the timer expires, release
- *         the rpipe [see rpipe_ep_disable()].
- *
- *     (b) when looking for free rpipes to attach [rpipe_get_by_ep()],
- *         when none are found go over the list, check their endpoint
- *         and their activity record (if no last-xfer-done-ts in the
- *         last x seconds) take it
- *
- *     However, due to the fact that we have a set of limited
- *     resources (max-segments-at-the-same-time per xfer,
- *     xfers-per-ripe, blocks-per-rpipe, rpipes-per-host), at the end
- *     we are going to have to rebuild all this based on an scheduler,
- *     to where we have a list of transactions to do and based on the
- *     availability of the different required components (blocks,
- *     rpipes, segment slots, etc), we go scheduling them. Painful.

- * functions/operations that only deal with general Wireless USB HC
- * issues use this data type to refer to the host.
- *
- * @usb_hcd	   Instantiation of a USB host controller
- *                 (initialized by upper layer [HWA=HC or WHCI].
- *
- * @dev		   Device that implements this; initialized by the
- *                 upper layer (HWA-HC, WHCI...); this device should
- *                 have a refcount.
- *
- * @trust_timeout  After this time without hearing for device
- *                 activity, we consider the device gone and we have to
- *                 re-authenticate.
- *
- *                 Can be accessed w/o locking--however, read to a
- *                 local variable then use.
- *
- * @chid           WUSB Cluster Host ID: this is supposed to be a
- *                 unique value that doesn't change across reboots (so
- *                 that your devices do not require re-association).
- *
- *                 Read/Write protected by @mutex
- *
- * @dev_info       This array has ports_max elements. It is used to
- *                 give the HC information about the WUSB devices (see
- *                 'struct wusb_dev_info').
- *
- *	           For HWA we need to allocate it in heap; for WHCI it
- *                 needs to be permanently mapped, so we keep it for
- *                 both and make it easy. Call wusbhc->dev_info_set()
- *                 to update an entry.
- *
- * @ports_max	   Number of simultaneous device connections (fake
- *                 ports) this HC will take. Read-only.
- *
- * @port	   Array of port status for each fake root port. Guaranteed to
- *                 always be the same length during device existence
- *                 [this allows for some unlocked but referenced reading].
- *
- * @mmcies_max	   Max number of Information Elements this HC can send
- *                 in its MMC. Read-only.
- *
- * @start          Start the WUSB channel.
- *
- * @stop           Stop the WUSB channel after the specified number of
- *                 milliseconds.  Channel Stop IEs should be transmitted
- *                 as required by [WUSB] 4.16.2.1.
- *
- * @mmcie_add	   HC specific operation (WHCI or HWA) for adding an
- *                 MMCIE.
- *
- * @mmcie_rm	   HC specific operation (WHCI or HWA) for removing an
- *                 MMCIE.
- *
- * @set_ptk:       Set the PTK and enable encryption for a device. Or, if
- *                 the supplied key is NULL, disable encryption for that
- *                 device.
- *
- * @set_gtk:       Set the GTK to be used for all future broadcast packets
- *                 (i.e., MMCs).  With some hardware, setting the GTK may start
- *                 MMC transmission.
- *
- * NOTE:
- *
- *  - If wusb_dev->usb_dev is not NULL, then usb_dev is valid
- *    (wusb_dev has a refcount on it). Likewise, if usb_dev->wusb_dev
- *    is not NULL, usb_dev->wusb_dev is valid (usb_dev keeps a
- *    refcount on it).
- *
- *    Most of the times when you need to use it, it will be non-NULL,
- *    so there is no real need to check for it (wusb_dev will
- *    disappear before usb_dev).
- *
- *  - The following fields need to be filled out before calling
- *    wusbhc_create(): ports_max, mmcies_max, mmcie_{add,rm}.
- *
- *  - there is no wusbhc_init() method, we do everything in
- *    wusbhc_create().
- *
- *  - Creation is done in two phases, wusbhc_create() and
- *    wusbhc_create_b(); b are the parts that need to be called after
- *    calling usb_hcd_add(&wusbhc->usb_hcd).
