drm: Add optional COLOR_ENCODING and COLOR_RANGE properties to drm_plane
Add a standard optional properties to support different non RGB color encodings in DRM planes. COLOR_ENCODING select the supported non RGB color encoding, for instance ITU-R BT.709 YCbCr. COLOR_RANGE selects the value ranges within the selected color encoding. The properties are stored to drm_plane object to allow different set of supported encoding for different planes on the device. v2: Add/fix kerneldocs, verify bitmasks (danvet) Cc: Harry Wentland <harry.wentland@amd.com> Cc: Daniel Vetter <daniel@ffwll.ch> Cc: Daniel Stone <daniel@fooishbar.org> Cc: Russell King - ARM Linux <linux@armlinux.org.uk> Cc: Ilia Mirkin <imirkin@alum.mit.edu> Cc: Hans Verkuil <hverkuil@xs4all.nl> Cc: Uma Shankar <uma.shankar@intel.com> Cc: Shashank Sharma <shashank.sharma@intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Jyri Sarha <jsarha@ti.com> [vsyrjala v2: Add/fix kerneldocs, verify bitmasks] Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180219202823.10508-1-ville.syrjala@linux.intel.com Acked-by: Harry Wentland <harry.wentland@amd.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch>
