H A D | drm_crtc.h | 3c9855f6 Tue Jul 08 00:01:56 CDT 2014 Ville Syrjälä <ville.syrjala@linux.intel.com> drm: Add drm_rotation_simplify()
drm_rotation_simplify() can be used to eliminate unsupported rotation flags. It will check if any unsupported flags are present, and if so it will modify the rotation to an alternate form by adding 180 degrees to rotation angle, and flipping the reflect x and y bits. The hope is that this identity transform will eliminate the unsupported flags.
Of course that might not result in any more supported rotation, so the caller is still responsible for checking the result afterwards.
