Subject: [PATCH AUTOSEL 6.0 25/30] drm/amd/display: Investigate tool reported FCLK P-state deviations
From: Nevenko Stupar <Nevenko.Stupar@....com>
[ Upstream commit 7461016c5706eb8c477752bf69e5c9f5a38f502b ]
[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.
