From b7ada7ee61d3eb0ebf08089edcefdc272b5f7b1e Mon Sep 17 00:00:00 2001 From: George Shen <george.shen@amd.com> Date: Thu, 14 Apr 2022 21:29:38 -0400 Subject: [PATCH] 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.
