 corresponding video timings. Today there are many more different hardware interfaces
 such as High Definition TV interfaces (HDMI), VGA, DVI connectors etc., that carry
 video signals and there is a need to extend the API to select the video timings
 for these interfaces. Since it is not possible to extend the &v4l2-std-id; due to
