Subject: [PATCH AUTOSEL 6.6 64/73] Re-revert "drm/amd/display: Enable Replay for static screen use cases"
From: Ivan Lipski <ivlipski@....com>
[ Upstream commit d6398866a6b47e92319ef6efdb0126a4fbb7796a ]
This reverts commit 44e60b14d5a72f91fd0bdeae8da59ae37a3ca8e5.
Since, it causes a regression in which eDP displays with PSR support,
but no Replay support (Sink support <= 0x03), fail to enable PSR and
consequently all IGT amd_psr tests fail. So, revert this until a more
suitable fix can be found.
This got brought back accidently with the backmerge.
