| 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, |
