From b8b92c1bd7788b1f13d547ee2ce8a93baf55b814 Mon Sep 17 00:00:00 2001 From: Melissa Wen Date: Thu, 16 Nov 2023 18:58:10 -0100 Subject: drm/amd/display: add plane CTM driver-specific property Plane CTM for pre-blending color space conversion. Only enable driver-specific plane CTM property on drivers that support both pre- and post-blending gamut remap matrix, i.e., DCN3+ family. Otherwise it conflits with DRM CRTC CTM property.
