[Intel-gfx] [PATCH v2 02/13] drm/i915/mtl: C20 HW readout

2023-04-28 Thread Mika Kahola
Create a table for C20 DP1.4, DP2.0 and HDMI2.1 rates. The PLL settings are based on table, not for algorithmic alternative. For DP 1.4 only MPLLB is in use. Once register settings are done, we read back C20 HW state. BSpec: 64568 v2: Updated pll tables (RK) MPLLB selection fix (RK)
