This set of patches is a continuation of DSC enablement
patches for AMDGPU. This set enables DSC on MST. It also
contains implementation of both encoder and connector
atomic check routines.

First 10 patches have been introduced in multiple
iterations to the mailing list before. These patches were
developed by David Francis as part of his work on DSC.

Other 3 patches add atomic check functionality to
encoder and connector to allocate and release VCPI
slots on each state atomic check. These changes
utilize newly added drm_mst_helper functions for
better tracking of VCPI slots.

v2: squashed previously 3 separate atomic check patches,
separate atomic check for dsc connectors, track vcpi and
pbn on connectors.

v3: Moved modeset trigger on affected MST displays to DRM

v4: Fix warnings, use current mode's bpc rather than display's
maximum capable one

David Francis (10):
  drm/dp_mst: Add PBN calculation for DSC modes
  drm/dp_mst: Parse FEC capability on MST ports
  drm/dp_mst: Add MST support to DP DPCD R/W functions
  drm/dp_mst: Fill branch->num_ports
  drm/dp_mst: Add helpers for MST DSC and virtual DPCD aux
  drm/amd/display: Initialize DSC PPS variables to 0
  drm/amd/display: Validate DSC caps on MST endpoints
  drm/amd/display: Write DSC enable to MST DPCD
  drm/amd/display: MST DSC compute fair share
  drm/dp_mst: Add new quirk for Synaptics MST hubs

Mikita Lipski (3):
  drm/amd/display: Add MST atomic routines
  drm/dp_mst: Add DSC enablement helpers to DRM
  drm/amd/display: Recalculate VCPI slots for new DSC connectors
