Ville Syrjälä 4e042f0222 drm/dp_mst: Fix fractional DSC bpp handling ... [ Upstream commit 7707dd6022 ] The current code does '(bpp << 4) / 16' in the MST PBN calculation, but that is just the same as 'bpp' so the DSC codepath achieves absolutely nothing. Fix it up so that the fractional part of the bpp value is actually used instead of truncated away. 64*1006 has enough zero lsbs that we can just shift that down in the dividend and thus still manage to stick to a 32bit divisor. And while touching this, let's just make the whole thing more straightforward by making the passed in bpp value .4 binary fixed point always, instead of having to pass in different things based on whether DSC is enabled or not. v2: - Fix DSC kunit test cases.
