[PATCH 00/10] Add support for 3 VDSC engines 12 slices

[Ankit Nautiyal]

For BMG 3 VDSC engines are supported and each pipe can then support
3 slices. For Ultra joiner cases for modes like 8k at 120 Hz we require
ultrajoiner and 3 x 4= 12 slices.
Add support for 3 VDSC engines and 12 DSC slices. Along with this
Pixel replication and Odd pixel considerartions are also required.

Rev2: Rebase
Rev3:
-Add patch to account for pixel replication in pipe_src.
-Fix kernel test bot warning.
-Minor refactoring.

Ankit Nautiyal (10):
  drm/i915/display: Prepare for dsc 3 stream splitter
  drm/i915/vdsc: Use VDSC0/VDSC1 for LEFT/RIGHT VDSC engine
  drm/i915/vdsc: Add register bits for VDSC2 engine
  drm/i915/vdsc: Add support for read/write PPS for DSC3
  drm/i915/dp: Add check for hdisplay divisible by slice count
  drm/i915/display: Add DSC pixel replication
  drm/i915/dp: Compute pixel replication count for DSC 12 slices case
  drm/i915/display: Account for pixel replication in pipe_src
  drm/i915/dsc: Account for Odd pixel removal
  drm/i915/dp: Add support for 3 vdsc engines and 12 slices.
