[PATCH v5 00/13] DSC MST support for DRM and AMDGPU

[mikita.lipski at amd.com]

From: Mikita Lipski <mikita.lipski at amd.com>

Patches are based of amd-staging-drm-next, the follow up
set of patches will be sent for drm-tip

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.

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

v5: Moving branch's bandwidth validation to DRM,
Added function to enable DSC per port in DRM

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/dp_mst: Add DSC enablement helpers to DRM
  drm/dp_mst: Add branch bandwidth validation to MST atomic check
  drm/amd/display: Recalculate VCPI slots for new DSC connectors
