-	tristate "WMI (EXPERIMENTAL)"
-	depends on X86
-	depends on EXPERIMENTAL
-	help
-	  This driver adds support for the ACPI-WMI (Windows Management
-	  Instrumentation) mapper device (PNP0C14) found on some systems.
-
-	  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.
-
-	  It is safe to enable this driver even if your DSDT doesn't define
-	  any ACPI-WMI devices.

-config ACPI_ASUS
-        tristate "ASUS/Medion Laptop Extras"
-	depends on X86
-	select BACKLIGHT_CLASS_DEVICE
-        ---help---
-          This driver provides support for extra features of ACPI-compatible
-          ASUS laptops. As some of Medion laptops are made by ASUS, it may also
-          support some Medion laptops (such as 9675 for example).  It makes all
-          the extra buttons generate standard ACPI events that go through
-          /proc/acpi/events, and (on some models) adds support for changing the
-          display brightness and output, switching the LCD backlight on and off,
-          and most importantly, allows you to blink those fancy LEDs intended
-          for reporting mail and wireless status.
-
-	  Note: display switching code is currently considered EXPERIMENTAL,
-	  toying with these values may even lock your machine.
-
-          All settings are changed via /proc/acpi/asus directory entries. Owner
-          and group for these entries can be set with asus_uid and asus_gid
-          parameters.
-
-          More information and a userspace daemon for handling the extra buttons
-          at <http://sourceforge.net/projects/acpi4asus/>.
-
-          If you have an ACPI-compatible ASUS laptop, say Y or M here. This
-          driver is still under development, so if your laptop is unsupported or
-          something works not quite as expected, please use the mailing list
-          available on the above page (acpi4asus-user@lists.sourceforge.net).
-
-	  NOTE: This driver is deprecated and will probably be removed soon,
-	  use asus-laptop instead.

-config ACPI_TOSHIBA
-	tristate "Toshiba Laptop Extras"
-	depends on X86 && INPUT
-	select INPUT_POLLDEV
-	select NET
-	select RFKILL
-	select BACKLIGHT_CLASS_DEVICE
-	---help---
-	  This driver adds support for access to certain system settings
-	  on "legacy free" Toshiba laptops.  These laptops can be recognized by
-	  their lack of a BIOS setup menu and APM support.
-
-	  On these machines, all system configuration is handled through the
-	  ACPI.  This driver is required for access to controls not covered
-	  by the general ACPI drivers, such as LCD brightness, video output,
-	  etc.
-
-	  This driver differs from the non-ACPI Toshiba laptop driver (located
-	  under "Processor type and features") in several aspects.
-	  Configuration is accessed by reading and writing text files in the
-	  /proc tree instead of by program interface to /dev.  Furthermore, no
-	  power management functions are exposed, as those are handled by the
-	  general ACPI drivers.
-
-	  More information about this driver is available at
-	  <http://memebeam.org/toys/ToshibaAcpiDriver>.
-
-	  If you have a legacy free Toshiba laptop (such as the Libretto L1
-	  series), say Y.

+ * The subsystem keeps a global list of dma_device structs it is protected by a
+ * mutex, dma_list_mutex.
+ *
+ * A subsystem can get access to a channel by calling dmaengine_get() followed
+ * by dma_find_channel(), or if it has need for an exclusive channel it can call
+ * dma_request_channel().  Once a channel is allocated a reference is taken
+ * against its corresponding driver to disable removal.
  *
  * Each device has a channels list, which runs unlocked but is never modified
  * once the device is registered, it's just setup by the driver.
  *
- * Each client is responsible for keeping track of the channels it uses.  See
- * the definition of dma_event_callback in dmaengine.h.
- *
- * Each device has a kref, which is initialized to 1 when the device is
- * registered. A kref_get is done for each device registered.  When the
- * device is released, the corresponding kref_put is done in the release
- * method. Every time one of the device's channels is allocated to a client,
- * a kref_get occurs.  When the channel is freed, the corresponding kref_put
- * happens. The device's release function does a completion, so
- * unregister_device does a remove event, device_unregister, a kref_put
- * for the first reference, then waits on the completion for all other
- * references to finish.
- *
- * Each channel has an open-coded implementation of Rusty Russell's "bigref,"
- * with a kref and a per_cpu local_t.  A dma_chan_get is called when a client
- * signals that it wants to use a channel, and dma_chan_put is called when
- * a channel is removed or a client using it is unregistered.  A client can
- * take extra references per outstanding transaction, as is the case with
- * the NET DMA client.  The release function does a kref_put on the device.

+ *	priority = value to priorize clock sources (0 = default)
+ *	ctl = callback function to enable/disable clock source

+ *       Also it can be called during mISDN_unregister_clock.
+ *
+ * A clock source calls mISDN_clock_update with given samples elapsed, if

+ * of the actual event.
+ *
+ * A clock source unregisters using mISDN_unregister_clock.
+ *
+ * To get current clock, call mISDN_clock_get. The signed short value
+ * counts the number of samples since. Time since last clock event is added.

-	---help---
-	  Allows the thinkpad_acpi driver to provide an interface to control
-	  the various video output ports.
-
-	  This feature often won't work well, depending on ThinkPad model,
-	  display state, video output devices in use, whether there is a X
-	  server running, phase of the moon, and the current mood of
-	  Schroedinger's cat.  If you can use X.org's RandR to control
-	  your ThinkPad's video output ports instead of this feature,
-	  don't think twice: do it and say N here to save some memory.
-
-	  If you are not sure, say Y here.
-
-config THINKPAD_ACPI_HOTKEY_POLL
-	bool "Support NVRAM polling for hot keys"
-	depends on THINKPAD_ACPI
-	default y
-	---help---
-	  Some thinkpad models benefit from NVRAM polling to detect a few of
-	  the hot key press events.  If you know your ThinkPad model does not
-	  need to do NVRAM polling to support any of the hot keys you use,
-	  unselecting this option will save about 1kB of memory.
-
-	  ThinkPads T40 and newer, R52 and newer, and X31 and newer are
-	  unlikely to need NVRAM polling in their latest BIOS versions.
-
-	  NVRAM polling can detect at most the following keys: ThinkPad/Access
-	  IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
-	  Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
-
-	  If you are not sure, say Y here.  The driver enables polling only if
-	  it is strictly necessary to do so.

+ * Pointer to skb containing the ack message. You need to check the

+ *
+ *  - the message wasn't formatted correctly
+ *  - couldn't send the message
+ *  - failed waiting for a response
+ *  - the ack message wasn't formatted correctly
+ *
+ * The returned skb has been allocated with wimax_msg_to_user_alloc(),

+ *
+ * This function delivers a message/command to the device and waits

+ *
+ * This function will not check the ack status, that's left up to the
+ * caller.  Once done with the ack skb, it has to be kfree_skb()ed.
+ *
+ * The i2400m handles only one message at the same time, thus we need
+ * the mutex to exclude other players.
+ *
+ * We write the message and then wait for an answer to come back. The
+ * RX path intercepts control messages and handles them in
+ * i2400m_rx_ctl(). Reports (notifications) are (maybe) processed
+ * locally and then forwarded (as needed) to user space on the WiMAX
+ * stack message pipe. Acks are saved and passed back to us through an
+ * skb in i2400m->ack_skb which is ready to be given to generic
+ * netlink if need be.

+ *     done, you have to (1) i2400m_put(i2400m_work->i2400m) and then

+ *
+ * @gfp_flags: GFP flags for memory allocation.

+ * @pl: pointer to a payload buffer that you want to pass to the _work
+ *     function. Use this to pack (for example) a struct with extra

+ *
+ * @pl_size: size of the payload buffer.
+ *

+ * the work.

+ *                   &args, sizeof(args))

+ *  - Initial implementation
+ *
+ *
+ * THE PROCEDURE
+ *
+ * (this is decribed for USB, but for SDIO is similar)
+ *
+ * The 2400m works in two modes: boot-mode or normal mode. In boot
+ * mode we can execute only a handful of commands targeted at
+ * uploading the firmware and launching it.
+ *
+ * The 2400m enters boot mode when it is first connected to the
+ * system, when it crashes and when you ask it to reboot. There are
+ * two submodes of the boot mode: signed and non-signed. Signed takes
+ * firmwares signed with a certain private key, non-signed takes any
+ * firmware. Normal hardware takes only signed firmware.
+ *
+ * Upon entrance to boot mode, the device sends a few zero length
+ * packets (ZLPs) on the notification endpoint, then a reboot barker
+ * (4 le32 words with value I2400M_{S,N}BOOT_BARKER). We ack it by
+ * sending the same barker on the bulk out endpoint. The device acks
+ * with a reboot ack barker (4 le32 words with value 0xfeedbabe) and
+ * then the device is fully rebooted. At this point we can upload the
+ * firmware.
+ *
+ * This process is accomplished by the i2400m_bootrom_init()
+ * function. All the device interaction happens through the
+ * i2400m_bm_cmd() [boot mode command]. Special return values will
+ * indicate if the device resets.
+ *
+ * After this, we read the MAC address and then (if needed)
+ * reinitialize the device. We need to read it ahead of time because
+ * in the future, we might not upload the firmware until userspace
+ * 'ifconfig up's the device.
+ *
+ * We can then upload the firmware file. The file is composed of a BCF
+ * header (basic data, keys and signatures) and a list of write
+ * commands and payloads. We first upload the header
+ * [i2400m_dnload_init()] and then pass the commands and payloads
+ * verbatim to the i2400m_bm_cmd() function
+ * [i2400m_dnload_bcf()]. Then we tell the device to jump to the new
+ * firmware [i2400m_dnload_finalize()].
+ *
+ * Once firmware is uploaded, we are good to go :)
+ *
+ * When we don't know in which mode we are, we first try by sending a
+ * warm reset request that will take us to boot-mode. If we time out
+ * waiting for a reboot barker, that means maybe we are already in
+ * boot mode, so we send a reboot barker.
+ *
+ * COMMAND EXECUTION
+ *
+ * This code (and process) is single threaded; for executing commands,
+ * we post a URB to the notification endpoint, post the command, wait
+ * for data on the notification buffer. We don't need to worry about
+ * others as we know we are the only ones in there.
+ *
+ * BACKEND IMPLEMENTATION
+ *
+ * This code is bus-generic; the bus-specific driver provides back end
+ * implementations to send a boot mode command to the device and to
+ * read an acknolwedgement from it (or an asynchronous notification)
+ * from it.

+ * i2400m_bootrom_init - Reboots a powered device into boot mode
+ *
+ * @i2400m: device descriptor
+ * @flags:
+ *      I2400M_BRI_SOFT: a reboot notification has been seen
+ *          already, so don't wait for it.
+ *
+ *      I2400M_BRI_NO_REBOOT: Don't send a reboot command, but wait
+ *          for a reboot barker notification. This is a one shot; if
+ *          the state machine needs to send a reboot command it will.
+ *
+ * Returns:
+ *
+ *     < 0 errno code on error, 0 if ok.
+ *
+ *     i2400m->sboot set to 0 for unsecure boot process, 1 for secure
+ *     boot process.
+ *
+ * Description:
+ *
+ * Tries hard enough to put the device in boot-mode. There are two
+ * main phases to this:
+ *
+ * a. (1) send a reboot command and (2) get a reboot barker
+ * b. (1) ack the reboot sending a reboot barker and (2) getting an
+ *        ack barker in return
+ *
+ * We want to skip (a) in some cases [soft]. The state machine is
+ * horrible, but it is basically: on each phase, send what has to be
+ * sent (if any), wait for the answer and act on the answer. We might
+ * have to backtrack and retry, so we keep a max tries counter for
+ * that.
+ *
+ * If we get a timeout after sending a warm reset, we do it again.

+ *  - Initial implementation
+ *
+ *
+ * GENERAL DRIVER ARCHITECTURE
+ *
+ * The i2400m driver is split in the following two major parts:
+ *
+ *  - bus specific driver
+ *  - bus generic driver (this part)
+ *
+ * The bus specific driver sets up stuff specific to the bus the
+ * device is connected to (USB, SDIO, PCI, tam-tam...non-authoritative
+ * nor binding list) which is basically the device-model management
+ * (probe/disconnect, etc), moving data from device to kernel and
+ * back, doing the power saving details and reseting the device.
+ *
+ * For details on each bus-specific driver, see it's include file,
+ * i2400m-BUSNAME.h
+ *
+ * The bus-generic functionality break up is:
+ *
+ *  - Firmware upload: fw.c - takes care of uploading firmware to the
+ *        device. bus-specific driver just needs to provides a way to
+ *        execute boot-mode commands and to reset the device.
+ *
+ *  - RX handling: rx.c - receives data from the bus-specific code and
+ *        feeds it to the network or WiMAX stack or uses it to modify
+ *        the driver state. bus-specific driver only has to receive
+ *        frames and pass them to this module.
+ *
+ *  - TX handling: tx.c - manages the TX FIFO queue and provides means
+ *        for the bus-specific TX code to pull data from the FIFO
+ *        queue. bus-specific code just pulls frames from this module
+ *        to sends them to the device.
+ *
+ *  - netdev glue: netdev.c - interface with Linux networking
+ *        stack. Pass around data frames, and configure when the
+ *        device is up and running or shutdown (through ifconfig up /
+ *        down). Bus-generic only.
+ *
+ *  - control ops: control.c - implements various commmands for
+ *        controlling the device. bus-generic only.
+ *
+ *  - device model glue: driver.c - implements helpers for the
+ *        device-model glue done by the bus-specific layer
+ *        (setup/release the driver resources), turning the device on
+ *        and off, handling the device reboots/resets and a few simple
+ *        WiMAX stack ops.
+ *
+ * Code is also broken up in linux-glue / device-glue.
+ *
+ * Linux glue contains functions that deal mostly with gluing with the
+ * rest of the Linux kernel.
+ *
+ * Device-glue are functions that deal mostly with the way the device
+ * does things and talk the device's language.
+ *
+ * device-glue code is licensed BSD so other open source OSes can take
+ * it to implement their drivers.
+ *
+ *
+ * APIs AND HEADER FILES
+ *
+ * This bus generic code exports three APIs:
+ *
+ *  - HDI (host-device interface) definitions common to all busses
+ *    (include/linux/wimax/i2400m.h); these can be also used by user
+ *    space code.
+ *  - internal API for the bus-generic code
+ *  - external API for the bus-specific drivers
+ *
+ *
+ * LIFE CYCLE:
+ *
+ * When the bus-specific driver probes, it allocates a network device
+ * with enough space for it's data structue, that must contain a
+ * &struct i2400m at the top.
+ *
+ * On probe, it needs to fill the i2400m members marked as [fill], as
+ * well as i2400m->wimax_dev.net_dev and call i2400m_setup(). The
+ * i2400m driver will only register with the WiMAX and network stacks;
+ * the only access done to the device is to read the MAC address so we
+ * can register a network device. This calls i2400m_dev_start() to
+ * load firmware, setup communication with the device and configure it
+ * for operation.
+ *
+ * At this point, control and data communications are possible.
+ *
+ * On disconnect/driver unload, the bus-specific disconnect function
+ * calls i2400m_release() to undo i2400m_setup(). i2400m_dev_stop()
+ * shuts the firmware down and releases resources uses to communicate
+ * with the device.
+ *
+ * While the device is up, it might reset. The bus-specific driver has
+ * to catch that situation and call i2400m_dev_reset_handle() to deal
+ * with it (reset the internal driver structures and go back to square
+ * one).

+/**
+ * struct i2400m - descriptor for an Intel 2400m
+ *
+ * Members marked with [fill] must be filled out/initialized before
+ * calling i2400m_setup().
+ *
+ * @bus_tx_block_size: [fill] SDIO imposes a 256 block size, USB 16,
+ *     so we have a tx_blk_size variable that the bus layer sets to
+ *     tell the engine how much of that we need.
+ *
+ * @bus_pl_size_max: [fill] Maximum payload size.
+ *
+ * @bus_dev_start: [fill] Function called by the bus-generic code
+ *     [i2400m_dev_start()] to setup the bus-specific communications
+ *     to the the device. See LIFE CYCLE above.
+ *
+ *     NOTE: Doesn't need to upload the firmware, as that is taken
+ *     care of by the bus-generic code.
+ *
+ * @bus_dev_stop: [fill] Function called by the bus-generic code
+ *     [i2400m_dev_stop()] to shutdown the bus-specific communications
+ *     to the the device. See LIFE CYCLE above.
+ *
+ *     This function does not need to reset the device, just tear down
+ *     all the host resources created to  handle communication with
+ *     the device.
+ *
+ * @bus_tx_kick: [fill] Function called by the bus-generic code to let
+ *     the bus-specific code know that there is data available in the
+ *     TX FIFO for transmission to the device.
+ *
+ *     This function cannot sleep.
+ *
+ * @bus_reset: [fill] Function called by the bus-generic code to reset
+ *     the device in in various ways. Doesn't need to wait for the
+ *     reset to finish.
+ *
+ *     If warm or cold reset fail, this function is expected to do a
+ *     bus-specific reset (eg: USB reset) to get the device to a
+ *     working state (even if it implies device disconecction).
+ *
+ *     Note the warm reset is used by the firmware uploader to
+ *     reinitialize the device.
+ *
+ *     IMPORTANT: this is called very early in the device setup
+ *     process, so it cannot rely on common infrastructure being laid
+ *     out.
+ *
+ * @bus_bm_cmd_send: [fill] Function called to send a boot-mode
+ *     command. Flags are defined in 'enum i2400m_bm_cmd_flags'. This
+ *     is synchronous and has to return 0 if ok or < 0 errno code in
+ *     any error condition.
+ *
+ * @bus_bm_wait_for_ack: [fill] Function called to wait for a
+ *     boot-mode notification (that can be a response to a previously
+ *     issued command or an asynchronous one). Will read until all the
+ *     indicated size is read or timeout. Reading more or less data
+ *     than asked for is an error condition. Return 0 if ok, < 0 errno
+ *     code on error.
+ *
+ *     The caller to this function will check if the response is a
+ *     barker that indicates the device going into reset mode.
+ *
+ * @bus_fw_name: [fill] name of the firmware image (in most cases,
+ *     they are all the same for a single release, except that they
+ *     have the type of the bus embedded in the name (eg:
+ *     i2400m-fw-X-VERSION.sbcf, where X is the bus name).
+ *
+ * @bus_bm_mac_addr_impaired: [fill] Set to true if the device's MAC
+ *     address provided in boot mode is kind of broken and needs to
+ *     be re-read later on.
+ *
+ *
+ * @wimax_dev: WiMAX generic device for linkage into the kernel WiMAX
+ *     stack. Due to the way a net_device is allocated, we need to
+ *     force this to be the first field so that we can get from
+ *     netdev_priv() the right pointer.
+ *
+ * @state: device's state (as reported by it)
+ *
+ * @state_wq: waitqueue that is woken up whenever the state changes
+ *
+ * @tx_lock: spinlock to protect TX members
+ *
+ * @tx_buf: FIFO buffer for TX; we queue data here
+ *
+ * @tx_in: FIFO index for incoming data. Note this doesn't wrap around
+ *     and it is always greater than @tx_out.
+ *
+ * @tx_out: FIFO index for outgoing data
+ *
+ * @tx_msg: current TX message that is active in the FIFO for
+ *     appending payloads.
+ *
+ * @tx_sequence: current sequence number for TX messages from the
+ *     device to the host.
+ *
+ * @tx_msg_size: size of the current message being transmitted by the
+ *     bus-specific code.
+ *
+ * @tx_pl_num: total number of payloads sent
+ *
+ * @tx_pl_max: maximum number of payloads sent in a TX message
+ *
+ * @tx_pl_min: minimum number of payloads sent in a TX message
+ *
+ * @tx_num: number of TX messages sent
+ *
+ * @tx_size_acc: number of bytes in all TX messages sent
+ *     (this is different to net_dev's statistics as it also counts
+ *     control messages).
+ *
+ * @tx_size_min: smallest TX message sent.
+ *
+ * @tx_size_max: biggest TX message sent.
+ *
+ * @rx_lock: spinlock to protect RX members
+ *
+ * @rx_pl_num: total number of payloads received
+ *
+ * @rx_pl_max: maximum number of payloads received in a RX message
+ *
+ * @rx_pl_min: minimum number of payloads received in a RX message
+ *
+ * @rx_num: number of RX messages received
+ *
+ * @rx_size_acc: number of bytes in all RX messages received
+ *     (this is different to net_dev's statistics as it also counts
+ *     control messages).
+ *
+ * @rx_size_min: smallest RX message received.
+ *
+ * @rx_size_max: buggest RX message received.
+ *
+ * @init_mutex: Mutex used for serializing the device bringup
+ *     sequence; this way if the device reboots in the middle, we
+ *     don't try to do a bringup again while we are tearing down the
+ *     one that failed.
+ *
+ *     Can't reuse @msg_mutex because from within the bringup sequence
+ *     we need to send messages to the device and thus use @msg_mutex.
+ *
+ * @msg_mutex: mutex used to send control commands to the device (we
+ *     only allow one at a time, per host-device interface design).
+ *
+ * @msg_completion: used to wait for an ack to a control command sent
+ *     to the device.
+ *
+ * @ack_skb: used to store the actual ack to a control command if the
+ *     reception of the command was successful. Otherwise, a ERR_PTR()
+ *     errno code that indicates what failed with the ack reception.
+ *
+ *     Only valid after @msg_completion is woken up. Only updateable
+ *     if @msg_completion is armed. Only touched by
+ *     i2400m_msg_to_dev().
+ *
+ *     Protected by @rx_lock. In theory the command execution flow is
+ *     sequential, but in case the device sends an out-of-phase or
+ *     very delayed response, we need to avoid it trampling current
+ *     execution.
+ *
+ * @bm_cmd_buf: boot mode command buffer for composing firmware upload
+ *     commands.
+ *
+ *     USB can't r/w to stack, vmalloc, etc...as well, we end up
+ *     having to alloc/free a lot to compose commands, so we use these
+ *     for stagging and not having to realloc all the time.
+ *
+ *     This assumes the code always runs serialized. Only one thread
+ *     can call i2400m_bm_cmd() at the same time.
+ *
+ * @bm_ack_buf: boot mode acknoledge buffer for staging reception of
+ *     responses to commands.
+ *
+ *     See @bm_cmd_buf.
+ *
+ * @work_queue: work queue for processing device reports. This
+ *     workqueue cannot be used for processing TX or RX to the device,
+ *     as from it we'll process device reports, which might require
+ *     further communication with the device.
+ *
+ * @debugfs_dentry: hookup for debugfs files.
+ *     These have to be in a separate directory, a child of
+ *     (wimax_dev->debugfs_dentry) so they can be removed when the
+ *     module unloads, as we don't keep each dentry.

+ * This implements an ethernet device for the i2400m.
+ *
+ * We fake being an ethernet device to simplify the support from user
+ * space and from the other side. The world is (sadly) configured to
+ * take in only Ethernet devices...
+ *
+ * Because of this, currently there is an copy-each-rxed-packet
+ * overhead on the RX path. Each IP packet has to be reallocated to
+ * add an ethernet header (as there is no space in what we get from
+ * the device). This is a known drawback and coming versions of the
+ * device's firmware are being changed to add header space that can be
+ * used to insert the ethernet header without having to reallocate and
+ * copy.
+ *
+ * TX error handling is tricky; because we have to FIFO/queue the
+ * buffers for transmission (as the hardware likes it aggregated), we
+ * just give the skb to the TX subsystem and by the time it is
+ * transmitted, we have long forgotten about it. So we just don't care
+ * too much about it.
+ *
+ * Note that when the device is in idle mode with the basestation, we
+ * need to negotiate coming back up online. That involves negotiation
+ * and possible user space interaction. Thus, we defer to a workqueue
+ * to do all that. By default, we only queue a single packet and drop
+ * the rest, as potentially the time to go back from idle to normal is
+ * long.

+ *
+ * THe generic firmware upload code will call i2400m_bus_bm_cmd_send()

+ * The SDIO devices expects things in 256 byte blocks, so it will pad

+ *
+ * ACK RECEPTION
+ *
+ * This works in polling mode -- the fw loader says when to wait for
+ * data and for that it calls i2400ms_bus_bm_wait_for_ack().
+ *
+ * This will poll the device for data until it is received. We need to
+ * receive at least as much bytes as where asked for (although it'll
+ * always be a multiple of 256 bytes).

+ *  - Initial implementation
+ *
+ * Intel Corporation <linux-wimax@intel.com>
+ * Inaky Perez-Gonzalez <inaky.perez-gonzalez@intel.com>
+ *  - Rewritten to use a single FIFO to lower the memory allocation
+ *    pressure and optimize cache hits when copying to the queue, as
+ *    well as splitting out bus-specific code.
+ *
+ *
+ * Implements data transmission to the device; this is done through a
+ * software FIFO, as data/control frames can be coalesced (while the
+ * device is reading the previous tx transaction, others accumulate).
+ *
+ * A FIFO is used because at the end it is resource-cheaper that trying
+ * to implement scatter/gather over USB. As well, most traffic is going
+ * to be download (vs upload).
+ *
+ * The format for sending/receiving data to/from the i2400m is
+ * described in detail in rx.c:PROTOCOL FORMAT. In here we implement
+ * the transmission of that. This is split between a bus-independent
+ * part that just prepares everything and a bus-specific part that
+ * does the actual transmission over the bus to the device (in the
+ * bus-specific driver).
+ *
+ *
+ * The general format of a device-host transaction is MSG-HDR, PLD1,
+ * PLD2...PLDN, PL1, PL2,...PLN, PADDING.
+ *
+ * Because we need the send payload descriptors and then payloads and
+ * because it is kind of expensive to do scatterlists in USB (one URB
+ * per node), it becomes cheaper to append all the data to a FIFO
+ * (copying to a FIFO potentially in cache is cheaper).
+ *
+ * Then the bus-specific code takes the parts of that FIFO that are
+ * written and passes them to the device.
+ *
+ * So the concepts to keep in mind there are:
+ *
+ * We use a FIFO to queue the data in a linear buffer. We first append
+ * a MSG-HDR, space for I2400M_TX_PLD_MAX payload descriptors and then
+ * go appending payloads until we run out of space or of payload
+ * descriptors. Then we append padding to make the whole transaction a
+ * multiple of i2400m->bus_tx_block_size (as defined by the bus layer).
+ *
+ * - A TX message: a combination of a message header, payload
+ *   descriptors and payloads.
+ *
+ *     Open: it is marked as active (i2400m->tx_msg is valid) and we
+ *       can keep adding payloads to it.
+ *
+ *     Closed: we are not appending more payloads to this TX message
+ *       (exahusted space in the queue, too many payloads or
+ *       whichever).  We have appended padding so the whole message
+ *       length is aligned to i2400m->bus_tx_block_size (as set by the
+ *       bus/transport layer).
+ *
+ * - Most of the time we keep a TX message open to which we append
+ *   payloads.
+ *
+ * - If we are going to append and there is no more space (we are at
+ *   the end of the FIFO), we close the message, mark the rest of the
+ *   FIFO space unusable (skip_tail), create a new message at the
+ *   beginning of the FIFO (if there is space) and append the message
+ *   there.
+ *
+ *   This is because we need to give linear TX messages to the bus
+ *   engine. So we don't write a message to the remaining FIFO space
+ *   until the tail and continue at the head of it.
+ *
+ * - We overload one of the fields in the message header to use it as
+ *   'size' of the TX message, so we can iterate over them. It also
+ *   contains a flag that indicates if we have to skip it or not.
+ *   When we send the buffer, we update that to its real on-the-wire
+ *   value.
+ *
+ * - The MSG-HDR PLD1...PLD2 stuff has to be a size multiple of 16.
+ *
+ *   It follows that if MSG-HDR says we have N messages, the whole
+ *   header + descriptors is 16 + 4*N; for those to be a multiple of
+ *   16, it follows that N can be 4, 8, 12, ... (32, 48, 64, 80...
+ *   bytes).
+ *
+ *   So if we have only 1 payload, we have to submit a header that in
+ *   all truth has space for 4.
+ *
+ *   The implication is that we reserve space for 12 (64 bytes); but
+ *   if we fill up only (eg) 2, our header becomes 32 bytes only. So
+ *   the TX engine has to shift those 32 bytes of msg header and 2
+ *   payloads and padding so that right after it the payloads start
+ *   and the TX engine has to know about that.
+ *
+ *   It is cheaper to move the header up than the whole payloads down.
+ *
+ *   We do this in i2400m_tx_close(). See 'i2400m_msg_hdr->offset'.
+ *
+ * - Each payload has to be size-padded to 16 bytes; before appending
+ *   it, we just do it.
+ *
+ * - The whole message has to be padded to i2400m->bus_tx_block_size;
+ *   we do this at close time. Thus, when reserving space for the
+ *   payload, we always make sure there is also free space for this
+ *   padding that sooner or later will happen.
+ *
+ * When we append a message, we tell the bus specific code to kick in
+ * TXs. It will TX (in parallel) until the buffer is exhausted--hence
+ * the lockin we do. The TX code will only send a TX message at the
+ * time (which remember, might contain more than one payload). Of
+ * course, when the bus-specific driver attempts to TX a message that
+ * is still open, it gets closed first.
+ *
+ * Gee, this is messy; well a picture. In the example below we have a
+ * partially full FIFO, with a closed message ready to be delivered
+ * (with a moved message header to make sure it is size-aligned to
+ * 16), TAIL room that was unusable (and thus is marked with a message
+ * header that says 'skip this') and at the head of the buffer, an
+ * imcomplete message with a couple of payloads.

+ *
+ * COMMAND EXECUTION
+ *
+ * A write URB is posted with the buffer to the bulk output endpoint.

+ * ACK RECEPTION
+ *
+ * We just post a URB to the notification endpoint and wait for

+ * The data is not read from the bulk in endpoint for boot mode.

+ *  - Split transport/device specific
+ *  - Make buffer size dynamic to exert less memory pressure
+ *
+ *
+ * This handles the RX path on USB.
+ *
+ * When a notification is received that says 'there is RX data ready',
+ * we call i2400mu_rx_kick(); that wakes up the RX kthread, which
+ * reads a buffer from USB and passes it to i2400m_rx() in the generic
+ * handling code. The RX buffer has an specific format that is
+ * described in rx.c.
+ *
+ * We use a kernel thread in a loop because:
+ *
+ *  - we want to be able to call the USB power management get/put
+ *    functions (blocking) before each transaction.
+ *
+ *  - We might get a lot of notifications and we don't want to submit
+ *    a zillion reads; by serializing, we are throttling.
+ *
+ *  - RX data processing can get heavy enough so that it is not
+ *    appropiate for doing it in the USB callback; thus we run it in a
+ *    process context.
+ *
+ * We provide a read buffer of an arbitrary size (short of a page); if
+ * the callback reports -EOVERFLOW, it means it was too small, so we
+ * just double the size and retry (being careful to append, as
+ * sometimes the device provided some data). Every now and then we
+ * check if the average packet size is smaller than the current packet
+ * size and if so, we halve it. At the end, the size of the
+ * preallocated buffer should be following the average received
+ * transaction size, adapting dynamically to it.

+	  This driver adds support for the ACPI-WMI (Windows Management
+	  Instrumentation) mapper device (PNP0C14) found on some systems.
+
+	  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.
+
+	  It is safe to enable this driver even if your DSDT doesn't define
+	  any ACPI-WMI devices.

+	  This driver provides support for extra features of ACPI-compatible
+	  ASUS laptops. As some of Medion laptops are made by ASUS, it may also
+	  support some Medion laptops (such as 9675 for example).  It makes all
+	  the extra buttons generate standard ACPI events that go through
+	  /proc/acpi/events, and (on some models) adds support for changing the
+	  display brightness and output, switching the LCD backlight on and off,
+	  and most importantly, allows you to blink those fancy LEDs intended
+	  for reporting mail and wireless status.
+
+	  Note: display switching code is currently considered EXPERIMENTAL,
+	  toying with these values may even lock your machine.
+
+	  All settings are changed via /proc/acpi/asus directory entries. Owner
+	  and group for these entries can be set with asus_uid and asus_gid
+	  parameters.
+
+	  More information and a userspace daemon for handling the extra buttons
+	  at <http://sourceforge.net/projects/acpi4asus/>.
+
+	  If you have an ACPI-compatible ASUS laptop, say Y or M here. This
+	  driver is still under development, so if your laptop is unsupported or
+	  something works not quite as expected, please use the mailing list
+	  available on the above page (acpi4asus-user@lists.sourceforge.net).

+	  This driver adds support for access to certain system settings
+	  on "legacy free" Toshiba laptops.  These laptops can be recognized by
+	  their lack of a BIOS setup menu and APM support.
+
+	  On these machines, all system configuration is handled through the
+	  ACPI.  This driver is required for access to controls not covered
+	  by the general ACPI drivers, such as LCD brightness, video output,
+	  etc.
+
+	  This driver differs from the non-ACPI Toshiba laptop driver (located
+	  under "Processor type and features") in several aspects.
+	  Configuration is accessed by reading and writing text files in the
+	  /proc tree instead of by program interface to /dev.  Furthermore, no
+	  power management functions are exposed, as those are handled by the
+	  general ACPI drivers.
+
+	  More information about this driver is available at
+	  <http://memebeam.org/toys/ToshibaAcpiDriver>.
+
+	  If you have a legacy free Toshiba laptop (such as the Libretto L1
+	  series), say Y.

+ * usb_queue_reset_device - Reset a USB device from an atomic context
+ * @iface: USB interface belonging to the device to reset
+ *
+ * This function can be used to reset a USB device from an atomic
+ * context, where usb_reset_device() won't work (as it blocks).
+ *
+ * Doing a reset via this method is functionally equivalent to calling
+ * usb_reset_device(), except for the fact that it is delayed to a
+ * workqueue. This means that any drivers bound to other interfaces
+ * might be unbound, as well as users from usbfs in user space.
+ *
+ * Corner cases:
+ *
+ * - Scheduling two resets at the same time from two different drivers
+ *   attached to two different interfaces of the same device is
+ *   possible; depending on how the driver attached to each interface
+ *   handles ->pre_reset(), the second reset might happen or not.
+ *
+ * - If a driver is unbound and it had a pending reset, the reset will
+ *   be cancelled.
+ *
+ * - This function can be called during .probe() or .disconnect()
+ *   times. On return from .disconnect(), any pending resets will be
+ *   cancelled.
+ *
+ * There is no no need to lock/unlock the @reset_ws as schedule_work()
+ * does its own.
+ *
+ * NOTE: We don't do any reference count tracking because it is not
+ *     needed. The lifecycle of the work_struct is tied to the
+ *     usb_interface. Before destroying the interface we cancel the
+ *     work_struct, so the fact that work_struct is queued and or
+ *     running means the interface (and thus, the device) exist and
+ *     are referenced.

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