[Intel-gfx] [PATCH] drm/i915/display: Skip state verification with TBT-ALT mode

2023-11-29 Thread Mika Kahola
With TBT-ALT mode we are not programming C20 chip PLL's and hence we don't need to check state verification. We don't need to program DP link signal levels i.e.pre-emphasis and voltage swing either. This patch fixes dmesg errors like this one "[drm] ERROR PHY F Write 0c06 failed after 3
