Hi Michael, Thank you for the patch series. On Mon, May 31, 2021 at 12:22:36AM +0200, Michael Grzeschik wrote:
This series improves the uvc video gadget by parsing the configfs entries. With the configfs data, the driver now is able to negotiate the format with the usb host in the kernel and also exports the supported frames/formats/intervals via the v4l2 VIDIOC interface.
Sorry for the delay, I'll start looking at this (and your other series) now. Paul
