USB gadget: video class function driver This USB video class function driver implements a video capture device from the host's point of view. It creates a V4L2 output device on the gadget's side to transfer data from a userspace application over USB. The UVC-specific descriptors are passed by the gadget driver to the UVC function driver, making them completely configurable without any modification to the function's driver code.

V4L/DVB: uvc: Move constants and structures definitions to linux/usb/video.h The UVC host and gadget drivers both define constants and structures in private header files. Move all those definitions to linux/usb/video.h where they can be shared by the two drivers (and be available for userspace applications).

usb: gadget: uvc: Add super-speed support to UVC webcam gadget This patch adds super-speed support to UVC webcam gadget. Also in this patch: - We add the configurability to pass bInterval, bMaxBurst, mult factors for video streaming endpoint (ISOC IN) through module parameters. - We use config_ep_by_speed helper routine to configure video streaming endpoint.
