Subject: drm/amd/display: Add DCN3.1 Yellow Carp support to DM
X-Git-Url: https://git.baikalelectronics.ru/sdk/?a=commitdiff_plain;h=1ebcaebdb51514689daddbc306b0943afa5b0130;p=kernel.git

drm/amd/display: Add DCN3.1 Yellow Carp support to DM

To detect DCN3.1 ASICs and to enable the appropriate number of CRTCs,
pick the right validation paths for display formats and to use the
right DC interfaces.
