[Intel-gfx] [PATCH 15/17] drm/i915/dg2: use 128b/132b transcoder DDI mode

2021-08-18 Thread Jani Nikula
128b/132b has a separate transcoder DDI mode, which also requires the MST transport select to be set. Note that we'll use DP MST also for single-stream 128b/132b. Having the FDI and 128b/132b modes share the register mode value complicates things a bit. Bspec: 50493 Signed-off-by: Jani Nikula --
