* drm: Nuke drm_atomic_helper_plane_set_propertyDaniel Vetter2017-08-081-1/+0Star

* drm: stm: remove dead code and pointless local lut storagePeter Rosin2017-08-042-13/+0Star
| | | | | | | | | | | | | The redundant fb helper .load_lut is no longer used, and can not work right without also providing the fb helpers .gamma_set and .gamma_get thus rendering the code in this driver suspect.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the plumbing for supporting fb modifiers on planes. Modifiers have already been introduced to some extent, but this series will extend this to allow querying modifiers per plane.

This patch simply allows the DRM drivers to initialize their list of supported modifiers upon initializing the plane. v2: A minor addition from Daniel v3: * Updated commit message * s/INVALID/DRM_FORMAT_MOD_INVALID (Liviu) * Remove some excess newlines (Liviu) * Update comment for > 64 modifiers (Liviu) v4: Minor comment adjustments (Liviu) v5: Some new platforms added due to rebase v6: Add some missed plane inits (or maybe they're new - who knows at this point) (Daniel) Signed-off-by: Ben Widawsky <ben@bwidawsk.net> Reviewed-by: Daniel Stone <daniels@collabora.com> (v2) Reviewed-by: Liviu Dudau <Liviu.Dudau@arm.com> Signed-off-by: Daniel Stone <daniels@collabora.com>
