[PATCH v9] drm/dp_mst: Add PBN calculation for DSC modes

2019-12-03 Thread mikita.lipski
From: David Francis With DSC, bpp can be fractional in multiples of 1/16. Change drm_dp_calc_pbn_mode to reflect this, adding a new parameter bool dsc. When this parameter is true, treat the bpp parameter as having units not of bits per pixel, but 1/16 of a bit per pixel v2: Don't add separate
