[PATCH 5.19 0344/1157] drm/amdgpu/display: Prepare for new interfaces

Greg Kroah-Hartman
2022-08-15T23:28:22Z

From: Leung, Martin <Martin.Leung@amd.com>

[ Upstream commit a820190204aef0739aa3a067d00273d117f9367c ]

why:
lut pipeline will be hooked up differently in some asics
need to add new interfaces

how:
add them
