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.
