Subject[PATCH v3 0/8] [PATCH 0/8] uvcvideo: Fixes for hw timestamping
From
Date
Add some fixes for fixing hw timestamp on some Logitech and SunplusIT
cameras. The issues have been previously reported to the manufacturers.

Also include a patch to fix the current hw timestamping logic for ANY
uvc 1.5 model running at under 16 fps.
