Patches 1-4 are DSC fixes from series to Handle BPC for HDMI2.1 PCON https://patchwork.freedesktop.org/series/107550/ Patches 5-6 are from series DSC fixes for Bigjoiner: https://patchwork.freedesktop.org/series/115773/ Patches 7-17 are based on series to add DSC fractional BPP support: https://patchwork.freedesktop.org/series/111391/ Patch 18 is to fix compressed bpc for MST DSC, from Stan's series : https://patchwork.freedesktop.org/series/116179/ Rev2: Addressed review comments from Stan, Ville. Rev3: Split larger patches. Separate out common helpers. Rev4: Rebased, fixed checkpatch warnings. Rev5: Addressed review comments from Stan. Added a patch to check if forced dsc format can be used before forcing.
