The current code stops at the HDMI 2.1 ceiling of 12 Gbps per lane, so a sink that advertises an HDMI 2.2 rate is treated as having no FRL support at all and the link ends up trained far below what the sink actually supports. Patch 1 teaches the DRM EDID parser to decode the three new rates. Patch 2 maps them back to the FRL rate index used by DC in amdgpu_dm and extends the KUnit coverage.
