This patchset tries to enhance the UVC webcam gadget driver and is based on
Laurent's git tree available here (head uvc-gadget):
git://linuxtv.org/pinchartl/uvcvideo.git
Note that to ease review and integration of these patches, I have rebased them
on Laurent's repo and all the relevant patches after review can be pushed in
Felipe's repo in one go.
The patch 1/2 in this patchset tries to handle all the review comments
received on the V5 of the following UVC gadget related patch:
[PATCH V5 1/2] usb: gadget/uvc: Port UVC webcam gadget to use
videobuf2 framework
which can be viewed here:
[1] http://www.spinics.net/lists/linux-usb/msg83430.html
The patch 2/2 in this patchset has already received an Acked-By from
Laurent.
I have tested this patchset on a super-speed compliant USB device controller
(DWC3), with the VIVI capture device acting as a dummy source of video data and
I also have modified the 'uvc-gadget' application written by Laurent
(original application available here:
http://git.ideasonboard.org/uvc-gadget.git)
for testing the complete flow from V4L2 to UVC domain and vice versa.
I will send a patch for the modified 'uvc-gadget' application in a separate
mail thread.
Changes since V5:
- Addresses the review comments received on V5 of this patchset from Laurent.
- The changes suggested by Laurent and Alan to remove WARN_ON messages
from the UDC controller drivers in case the gadget tries to dequeue a USB
request which was never queued to the UDC controller, will be floated
as a separate patch.
