-Subject: ARM: dts: imx6qdl-apalis: Fix poweroff on Apalis iMX6
-
-From: Stefan Eichenberger <stefan.eichenberger@toradex.com>
-
-commit 83964a29379cb08929a39172780a4c2992bc7c93 upstream.
-
-The current solution for powering off the Apalis iMX6 is not functioning
-as intended. To resolve this, it is necessary to power off the
-vgen2_reg, which will also set the POWER_ENABLE_MOCI signal to a low
-state. This ensures the carrier board is properly informed to initiate
-its power-off sequence.
-
-The new solution uses the regulator-poweroff driver, which will power
-off the regulator during a system shutdown.

-Subject: drm/amd/display: should support dmub hw lock on Replay
-
-From: Martin Tsai <martin.tsai@amd.com>
-
-commit bfeefe6ea5f18cabb8fda55364079573804623f9 upstream.
-
-[Why]
-Without acquiring DMCUB hw lock, a race condition is caused with
-Panel Replay feature, which will trigger a hang. Indicate that a
-lock is necessary to prevent this when replay feature is enabled.
-
-[How]
-To allow dmub hw lock on Replay.

-Subject: drm/amd/display: Use HW lock mgr for PSR1 when only one eDP
-
-From: Mario Limonciello <mario.limonciello@amd.com>
-
-commit acbf16a6ae775b4db86f537448cc466288aa307e upstream.
-
-[WHY]
-DMUB locking is important to make sure that registers aren't accessed
-while in PSR. Previously it was enabled but caused a deadlock in
-situations with multiple eDP panels.
-
-[HOW]
-Detect if multiple eDP panels are in use to decide whether to use
-lock. Refactor the function so that the first check is for PSR-SU
-and then replay is in use to prevent having to look up number
-of eDP panels for those configurations.
-
-Fixes: f245b400a223 ("Revert "drm/amd/display: Use HW lock mgr for PSR1"")
