[Intel-gfx] [PATCH v2 02/11] drm/dp_mst: Fix PBN divider calculation for UHBR rates

2023-11-16 Thread Imre Deak
The current way of calculating the pbn_div value, the link BW per each MTP slot, worked only for DP 1.4 link rates. Fix things up for UHBR rates calculating with the correct channel coding efficiency based on the link rate. v2: - Return the fractional pbn_div value from
