[PATCH 00/15] DSC MST support for AMDGPU

[mikita.lipski at amd.com]

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

This set of patches is a continuation of DSC enablement
patches for AMDGPU. This set enables DSC on MST.

First 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.

Other 12 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.

David Francis (12):
  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/dp_mst: Add new quirk for Synaptics MST hubs
  drm/amd/display: Use correct helpers to compute timeslots
  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/amd/display: Trigger modesets on MST DSC connectors

Mikita Lipski (3):
  drm/amdgpu: Add encoder atomic check
  drm/amdgpu: Add connector atomic check
  drm/amdgpu: validate mst topology in atomic check
