Subject: drm/amd/display: Investigate tool reported FCLK P-state deviations
Git-commit: 7461016c5706eb8c477752bf69e5c9f5a38f502b
Patch-mainline: v6.1-rc4
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225 jsc#PED-2849
[Why]
Fix for some of the tool reported modes for FCLK
P-state deviations and UCLK P-state deviations that
are coming from DSC terms and/or Scaling terms
causing MinActiveFCLKChangeLatencySupported
and MaxActiveDRAMClockChangeLatencySupported
incorrectly calculated in DML for these configurations.
