[PATCH v2 0/3] drm/msm: add RGB101010 pixel format and fix 10-bit DSC timing

Posted by Alexander Koskovich 2 weeks, 4 days ago

This series adds support for the RGB101010 (30bpp) pixel format and
fixes a DSC timing bug exposed by non 8 bit panels.

Tested on the BOE BF068MWM-TD0 panel (10 bit DSC) on the Nothing
Phone (3a).

Note, I'd appreciate a comment on the INTF timing change from someone
at QCOM who knows the DPU hardware a bit better, this appears to be
what downstream is doing regardless of bpp, but let me know if there's
a better solution here.
