[Intel-gfx] [PATCH v3 5/8] drm/i915/mtl: Add vswing programming for C10 phys

2023-04-06 Thread Mika Kahola
C10 phys uses direct mapping internally for voltage and pre-emphasis levels. Program the levels directly to the fields in the VDR Registers. Bspec: 65449 v2: From table "C10: Tx EQ settings for DP 1.4x" it shows level 1 and preemphasis 1 instead of two times of level 1 preemphasis 0. Fix
