    usb: gadget: core: fix bug when removing gadget drivers

    usb_gadget_disconnect() is responsible of removing
    data pullups. Before doing that we must, first, tell
    gadget driver we're disconnecting (by calling disconnect
    method on gadget driver structure), unbind the gadget
    driver and stop the controller.

Author: Paul Zimmerman <Paul.Zimmerman@synopsys.com>
Date:   Fri Sep 30 15:26:06 2011 -0700

    usb: gadget: storage: fix mass storage gadgets to work with Synopsys UDC

    The Synopsys USB device controller requires all OUT transfer request
    lengths to be aligned to max packet size. The mass storage gadgets do
    not meet this requirement for Super Speed. The gadgets already have a
    function which performs this alignment for CBW packets, so use it for
    data packets too.

    The alternative would be to implement bounce buffers in the DWC3
    driver, but that could have a significant impact on performance.

    This version is based upon a more-correct patch written by Alan
    Stern.

    USB: gadget: storage: remove alignment assumption

    This patch (as1481) fixes a problem affecting g_file_storage and
    g_mass_storage when running at SuperSpeed.  The two drivers currently
    assume that the bulk-out maxpacket size can evenly divide the SCSI
    block size, which is 512 bytes.  But SuperSpeed bulk endpoints have a
    maxpacket size of 1024, so the assumption is no longer true.

    This patch removes that assumption from the drivers, by getting rid of
    a small optimization (they try to align VFS reads and writes on page
    cache boundaries).  If a command's starting logical block address is
    512 bytes below the end of a page, it's not okay to issue a USB
    command for just those 512 bytes when the maxpacket size is 1024 -- it
    would result in either babble (for an OUT transfer) or a short packet
    (for an IN transfer).

    Also, for backward compatibility, the test for writes extending beyond
    the end of the backing storage has to be changed.  If the host tries
    to do this, we should accept the data that fits in the backing storage
    and ignore the rest.  Because the storage's end may not align with a
    USB packet boundary, this means we may have to accept a USB OUT
    transfer that extends beyond the end of the storage and then write out
    only the part of the data that fits.

    usb: gadget: storage: adapt logic block size to bound block devices

    Now the mass storage driver has fixed logic block size of 512 bytes.

    The mass storage gadget read/write bound devices only through VFS, so the
    bottom level devices actually are just RAW devices to the driver and connected
    PC. As a RAW, hosts can always format, read and write it right in 512 bytes
    logic block and don't care about the actual logic block size of devices bound
    to the gadget.

    But if we want to share the bound block device partition between target board
    and PC, in case the logic block size of the bound block device is 4KB, we
    execute the following steps:

    1. connect a board with mass storage gadget to PC(the board has set one
    	partition of on-board block device as file name of the mass storage)
    2. PC format the mass storage to VFAT by default logic block size and
    	read/write it
    3. disconnect boards from PC
    4. target board mount the partition as VFAT

    Step 4 will fail since kernel on target thinks the logic block size of the
    bound partition as 4KB.
    A typical error is "FAT: logical sector size too small for device (logical
    sector size = 512)"

    If we execute opposite steps:
    1. format the partition to VFAT on target board and read/write this partition
    2. connect the board to Windows PC as usb mass storage gadget, windows will
    	think the disk is not formatted

    So the conclusion is that only as a gadget, the mass storage driver has no any
    problem.  But being shared VFAT or other filesystem on PC and target board, it
    will fail.

    This patch adapts logic block size to bound block devices and fix the issue.

    usb: gadget: epautoconf: do not change number of streams

    We should not change gadget driver's descriptors just
    because we think it's right to do so.

    There are several of reasons which would support this
    statement but it suffices to say that this was probably
    never tested because it updates bmAttributes without
    asking the driver if it's ok to do so.

    This means that e.g. on UASP gadget it would enable
    stream support even for the command endpoint which must
    not have stream support enabled.

    In fact, this change is fixing the bug introduced by
    commit a59d6b91 (usb: gadget: add streams support to
    the gadget framework) which was caught when testing
    UASP gadget with dwc3 driver.

    usb: gadget: defer setting maxpacket till ->setup()

    maxpacket is set by the udc driver for ep0 very early. This value is
    copied by the function gadget used later for the USB_DT_DEVICE and
    USB_DT_DEVICE_QUALIFIER query. This seems to work fine so far. For USB3
    we need set a different value here. In SS speed it is 2^x with x=9 and
    in HS we set something <= 64. If the UDC starts in SS and continues in
    HS after the cable has been plugged it will report a too small value.
    There setting of this value is defered and taken automaticly from the
    ep0 pointer where the UDC driver can update it according to the speed it
    detected _after_ a cable has been plugged.

    SuperSpeed USB has defined a new descriptor, called
    the Binary Device Object Store (BOS) Descriptor. It
    has also changed a bit the definition of SET_FEATURE
    and GET_STATUS requests to add USB3-specific details.

    This patch implements both changes to the Composite

    This optimization spares the FDs from saving the
    endpoint chosen descriptor. This optimization is
    not full though. To fully exploit this change, one

    usb: gadget: convert all users to the new udc infrastructure

    peripheral drivers are using usb_add_gadget()/usb_del_gadget() to
    register/unregister to the udc-core.

    The udc-core will take the first available gadget driver and attach
    function driver which is calling usb_gadget_register_driver(). This is
    the same behaviour we have right now.

    Only dummy_hcd was tested, the others were compiled tested.

Date:   Tue Jun 28 16:33:46 2011 +0300

    usb: gadget: introduce UDC Class

    this class will be used to abstract away several of the duplicated
    operations scattered among the USB gadget controller drivers.

    Later, we can add an atomic notifier to tell interested drivers about
    what's happening with the controller. Notifications such as suspend,
    resume, enumerated, etc. will be useful, at a minimum, for implementing
    usb charger detection.

    As part of the converting process usb_gadget_probe_driver() is no longer
    part of each udc but pushed into the ->stap() callback. The same for his
    couterpart.

    The core is currently set explicit to 'n'. It will be changed to 'y' once
    all users are converted since it provides functions which clash with
    other drivers.

    Waiting for RxFIFO to drain caused problems when testing against

    After talking to one of the RTL engineers, he stated that we
    should _not_ wait for RxFIFO to drain.

    doing it again here will most likely corrupt the list.

    According to USB 3.0 Specification, a SetAddress()

    usb: dwc3: gadget: replace mdelay with udelay in the busy loop

    There are two spots where we wait until the HW finishes processing a
    certain command. Initially we had a few problems and we used 500ms as a
    limit to be on a the safe side. Paul Zimmerman mentioned this is little too
    much. After a debugging session, we noticed that we hardly ever go over 20us
    and didn't pass 30usec so far. Using mdelay() seems way overloaded.

    Giving the current numbers 500usec as the upper limit is more than  enough.
    Should it ever timeout then something is definitely wrong.

    While here, also replace the type with u32 since long does not really
    fit here.

    usb: dwc3: gadget: rework the dequeue on RESET & DISCONNECT

    - since a while we are disabling an endpoint and purging every requests on
      RESET and DISCONNECT which leads to a warning since the endpoint was
      disabled twice (once by the UDC, and second time by the gadget). I
      think UDC should nuke all requests because all those requests
      become invalid. It's gadget driver's responsability, though, to disable
      its used endpoints. This is done by merging dwc3_stop_active_transfer()
      and dwc3_gadget_nuke_reqs() into dwc3_remove_requests().

    - dwc3_stop_active_transfer() is now no longer called unconditionaly.
      This has the advantage that it is always called to disable an active
      transfer which means if res_trans_idx 0 than something went wrong and
      it is an error condition because we can't clean up the requests.

    - Remove the DWC3_EP_WILL_SHUTDOWN which was introduced while
      introducing the command complete part for dequeue. All requests on
      req_queued list should be removed during the dwc3_cleanup_done_reqs()
      callback so there is no reason to go through the list again.
      We consider it an error condition if requests are still on this
      list since we never queue TRB without LST=1 (the last requests has
      always LST=1, there are no requests with LST=0 behind it).

    usb: dwc3: ep0: simplify EP0 state machine

    The DesignWare USB3 core tells us which phase
    of a control transfer should be started, it
    also tells us which physical endpoint needs
    that transfer.

    With these two informations, we have all we
    need to simply EP0 handling quite a lot and
    get rid rid of the SW state machine tracking
    ep0 states.

    For achieving this perfectly, we needed to
    add support for situations where we get
    XferNotReady while endpoint is still busy
    and XferNotReady while gadget driver still
    hasn't queued a request.

    usb: dwc3: core: add defines for XferNotReady event on Control EPs

    The status field of the Transfer Not Read event
    is different on Control Endpoints. On this patch
    we are just adding the defines to be used on a
    later patch which will re-work the control endpoint
    handling.

    usb: dwc3: gadget: improve command completion debug message

    the previous message had too little meaning. Make
    it more human readable and use the macro we already
    had for extracting the command completion status out
    of DEPCMDn register.

    usb: dwc3: gadget: set request dma to invalid when unmapping

    if we don't set DMA address to invalid when unmapping,
    we might fall in a situation where request buffer
    can't be mapped to DMA again.

    usb: dwc3: gadget: use TRB type 6 for ISOC transfers

    Type 6 should be used for the first transfer during an interval. This is
    also what the reference driver is using. Type 7 seems to be for following
    or additional transfers within the same interval.

    usb: dwc3: gadget: reset resource index to zero

    If we collected two requests together (i.e. only the last of them has
    LST=1) then we only have to stop transfer once: The clean-up code will
    cleanup everything until first TRB with the LST bit set.
    After XferComplete this index should be no longer valid since there is
    no transfer pending.

    usb: dwc3: Introduce DesignWare USB3 DRD Driver

    The DesignWare USB3 is a highly
    configurable IP Core which can be
    instantiated as Dual-Role Device (DRD),
    Peripheral Only and Host Only (XHCI)
    configurations.

    Several other parameters can be configured
    like amount of FIFO space, amount of TX and
    RX endpoints, amount of Host Interrupters,
    etc.

    The current driver has been validated with
    a virtual model of version 1.73a of that core
    and with an FPGA burned with version 1.83a
    of the DRD core. We have support for PCIe
    bus, which is used on FPGA prototyping, and
    for the OMAP5, more adaptation (or glue)
    layers can be easily added and the driver
    is half prepared to handle any possible
    configuration the HW engineer has chosen
    considering we have the information on
    one of the GHWPARAMS registers to do
    runtime checking of certain features.

    More runtime checks can, and should, be added
    in order to make this driver even more flexible
    with regards to number of endpoints, FIFO sizes,
    transfer types, etc.

    While this supports only the device side, for
    now, we will add support for Host side (xHCI -
    see the updated series Sebastian has sent [1])
    and OTG after we have it all stabilized.
