[Intel-gfx] [PATCH v1] drm/i915: Use intel_plane_data_rate for min_cdclk calculation

2020-02-20 Thread Stanislav Lisovskiy
There seems to be a bit of confusing redundancy in a way, how plane data rate/min cdclk are calculated. In fact both min cdclk, pixel rate and plane data rate are all part of the same formula as per BSpec. However currently we have intel_plane_data_rate, which is used to calculate plane data rate
