Subject: [PATCH AUTOSEL 6.12 302/486] drm/amd/display: Fix BT2020 YCbCr limited/full range input
From: Ilya Bakoulin <Ilya.Bakoulin@....com>
[ Upstream commit 07bc2dcbcf403d47d6f305ef7f0d3d489491c5fb ]
[Why]
BT2020 YCbCr input is not handled properly when full range
quantization is used and limited range is not supported at all.
[How]
- Add enums for BT2020 YCbCr limited/full range
- Add limited range CSC matrix
