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