      usb: gadget: udc: net2280: Fix tmp reusage in net2280 driver · ef5e2fa9
      Raz Manor authored
      In the function scan_dma_completions() there is a reusage of tmp
      variable. That coused a wrong value being used in some case when
      reading a short packet terminated transaction from an endpoint,
      in 2 concecutive reads.
      
      This was my logic for the patch:
      
      The req->td->dmadesc equals to 0 iff:
      -- There was a transaction ending with a short packet, and
      -- The read() to read it was shorter than the transaction length, and
      -- The read() to complete it is longer than the residue.
      I believe this is true from the printouts of various cases,
      but I can't be positive it is correct.
      
      Entering this if, there should be no more data in the endpoint
      (a short packet terminated the transaction).
      If there is, the transaction wasn't really done and we should exit and
      wait for it to finish entirely. That is the inner if.
      That inner if should never happen, but it is there to be on the safe
      side. That is why it is marked with the comment /* paranoia */.
      The size of the data available in the endpoint is ep->dma->dmacount
      and it is read to tmp.
      This entire clause is based on my own educated guesses.
      
      If we passed that inner if without breaking in the original code,
      than tmp & DMA_BYTE_MASK_COUNT== 0.
      That means we will always pass dma bytes count of 0 to dma_done(),
      meaning all the requested bytes were read.
      
      dma_done() reports back to the upper layer that the request (read())
      was done and how many bytes were read.
      In the original code that would always be the request size,
      regardless of the actual size of the data.
      That did not make sense to me at all.
      
      However, the original value of tmp is req->td->dmacount,
      which is the dmacount value when the request's dma transaction was
      finished. And that is a much more reasonable value to report back to
      the caller.
      
      To recreate the problem:
      Read from a bulk out endpoint in a loop, 1024 * n bytes in each
      iteration.
      Connect the PLX to a host you can control.
      Send to that endpoint 1024 * n + x bytes,
      such that 0 < x < 1024 * n and (x % 1024) != 0
      You would expect the first read() to return 1024 * n
      and the second read() to return x.
      But you will get the first read to return 1024 * n
      and the second one to return 1024 * n.
      That is true for every positive integer n.

      usb: dwc3: gadget: Fix system suspend/resume on TI platforms · 1551e35e
      Roger Quadros authored
      On TI platforms (dra7, am437x), the DWC3_DSTS_DEVCTRLHLT bit is not set
      after the device controller is stopped via DWC3_DCTL_RUN_STOP.
      
      If we don't disconnect and stop the gadget, it stops working after a
      system resume with the trace below.
      
      There is no point in preventing gadget disconnect and gadget stop during
      system suspend/resume as we're going to suspend in any case, whether
      DEVCTRLHLT timed out or not.

      Revert "usb: gadget: uvc: Add missing call for additional setup data" · eb38d913
      Roger Quadros authored
      This reverts commit 4fbac520.
      
      This commit breaks g_webcam when used with uvc-gadget [1].
      
      The user space application (e.g. uvc-gadget) is responsible for
      sending response to UVC class specific requests on control endpoint
      in uvc_send_response() in uvc_v4l2.c.
      
      The bad commit was causing a duplicate response to be sent with
      incorrect response data thus causing UVC probe to fail at the host
      and broken control transfer endpoint at the gadget.

      usb: dwc3: gadget: properly increment dequeue pointer on ep_dequeue · cf3113d8
      Felipe Balbi authored
      If request was already started, this means we had to
      stop the transfer. With that we also need to ignore
      all TRBs used by the request, however TRBs can only
      be modified after completion of END_TRANSFER
      command. So what we have to do here is wait for
      END_TRANSFER completion and only after that jump
      over TRBs by clearing HWO and incrementing dequeue
      pointer.
      
      Note that we have 2 possible types of transfers
      here:
      
      i) Linear buffer request
      ii) SG-list based request
      
      SG-list based requests will have r->num_pending_sgs
      set to a valid number (> 0). Linear requests,
      normally use a single TRB.
      
      For each of these two cases, if r->unaligned flag is
      set, one extra TRB has been used to align transfer
      size to wMaxPacketSize.
      
      All of these cases need to be taken into
      consideration so we don't mess up our TRB ring
      pointers.

      usb: gadget: function: f_fs: pass companion descriptor along · 2bfa0719
      Felipe Balbi authored
      If we're dealing with SuperSpeed endpoints, we need
      to make sure to pass along the companion descriptor
      and initialize fields needed by the Gadget
      API. Eventually, f_fs.c should be converted to use
      config_ep_by_speed() like all other functions,
      though.

      usb: dwc3: gadget: make Set Endpoint Configuration macros safe · 7369090a
      Felipe Balbi authored
      Some gadget drivers are bad, bad boys. We notice
      that ADB was passing bad Burst Size which caused top
      bits of param0 to be overwritten which confused DWC3
      when running this command.
      
      In order to avoid future issues, we're going to make
      sure values passed by macros are always safe for the
      controller. Note that ADB still needs a fix to *not*
      pass bad values.

        This includes two branches for arm64 dt updates, both following up on
        earlier changes for the same platforms that are already merged:
      
        Samsung:
         - add USB3 support in Exynos7
         - minor PM related updates
      
        Amlogic:
         - new machines: WeTek Set-top-boxes
         - various devices added to DT
      
        There are also a couple of bugfixes that trickled in since the start
        of the merge window:
      
         - The moxart_defconfig was not building the intended platform
         - CPU-hotplug was broken on ux500
         - Coresight was broken on Juno (never worked)"
