[PATCH 0/4] drm/edid: Parse AMD VSDB FreeSync range in common code

[Alex Huang <Alex.Huang2@amd.com>]

This patch series implements parsing for AMD VSDB block's FreeSync
related data directly in the EDID common parser.

Some monitor manufacturers advertise their VRR capability exclusively
using the AMD VSDB block's FreeSync data fields, many other
manufacturers (notably pre EDID 1.4 monitors and some post 1.4 monitors)
also do not include the relevant continuous frequency feature flag in
the EDID. This makes it difficult to differentiate true VRR capability
from supporting a few refresh rates between the range specified in EDID
refresh rate range field in a spec compliant manner.

Incidentally also resolves a recent regression where amdgpu failed to
detect some DP monitors as VRR capable after EDID parser was moved to
DRM common.

Alex Huang (4):
  drm/edid: Parse AMD VSDB for FreeSync refresh range
  drm/amd/display: Use HDMI FreeSync range from common EDID parser
  drm/amd/display: Refactor FreeSync capability detection flow
  drm/amd/display: Remove unused DMCU/DMUB EDID CEA parser
