/*
|
||
|
|
* 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,
|
||
|
|
* along with potential device specific codes.
