[PATCH 83/89] drm/amd/display: Add DCN3.1 HWSEQ
Alex Deucher
alexander.deucher at amd.com
Wed Jun 2 16:49:02 UTC 2021
From: Nicholas Kazlauskas <nicholas.kazlauskas at amd.com>
Add DCN3.1 specific hardware sequence programming - extending off of
our existing DCN3/DCN2 support.
Extend stream hardware sequencing to include new DCCG programming.
