Just a quick note for those who are wondering: disp_format_s was a custom extension from a work-in-progress driver from Cisco. We are working hard on upstreaming it, and the final version won't have that change. Anyway, who exactly needs that information? Normally that information is set or queried via VIDIOC_ENUM/G/S/QUERY_DV_TIMINGS (ENUM and QUERY got merged in 3.5, see http://hverkuil.home.xs4all.nl/spec/media.html for the latest documentation on these new ioctls). I would expect that the combination of v4l2_mbus_framefmt + v4l2_dv_timings gives you the information you need.
