[RFC PATCH 09/40] drm/amd/display: move replace blob func to dm plane

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



>From amdgpu_dm_plane we can get it for both CRTC and plane color
properties. We are adding new plane properties for AMD driver-private
color mgmt.
