28 * We don't use the V4L header because
29 * 1) the fourcc codes are well defined and trivial to construct
30 * 2) we don't want user apps to have to pull in v4l headers just for fourcc
31 * 3) the v4l fourcc codes are mixed up with a bunch of other code and are
32 * part of the v4l API, so changing them to something linux-generic isn't
33 * feasible
34 *
35 * So the below includes the fourcc codes used by the DRM and its drivers,
36 * along with potential device specific codes.
