Any idea where this new documentation should go (Documentation/DocBook/video/video-bus-formats.xml) ? > > Incidentally, patch 2/5 in this series is missing a documentation update ;-) Yep, regarding this patch, I wonder if it's really necessary to add new formats to the v4l2_mbus_pixelcode enum. If we want to move to this new common definition (across the video related subsytems), we should deprecate the old enum v4l2_mbus_pixelcode, and this start by not adding new formats, don't you think ?
