Subject: drm/amd/display: Populate DP2.0 output type for DML pipe
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b7ada7ee61d3eb0ebf08089edcefdc272b5f7b1e;p=linux.git

drm/amd/display: Populate DP2.0 output type for DML pipe

[Why]
DCN3.2 DML logic uses a new output type for DP2.0,
which will enable validation to pass for higher BW
timings that require DP2.0 link rates.

[How]
Populate the DML pipe with DP2.0 output type if
the signal type of the pipe_ctx is 128b/132b.
