[PATCH for-5.10+] drm/bridge: lt9611: Fix PLL being unable to lock

by Amit Pundir

From: Robert Foss <robert.foss(a)linaro.org> [ Upstream commit 2a9df204be0bbb896e087f00b9ee3fc559d5a608 ] This fixes PLL being unable to lock, and is derived from an equivalent downstream commit. Available LT9611 documentation does not list this register, neither does LT9611UXC (which is a different chip). This commit has been confirmed to fix HDMI output on DragonBoard 845c.

[PATCH 6.1.y 0/2] MST Fixups in 6.1.y

by Mario Limonciello

Hi, Some MST fixups that landed in 6.3-rc1 were CC to stable and successfully applied to 6.2.y, but failed to apply to 6.1.y even though they are needed there as well. They fail to apply due to this commit missing in 6.1.y: commit 8c7d980da9ba ("drm/nouveau/disp: move DP MST payload config method") Backporting that is a rabbit hole of other work and makes this no longer viable for stable, so instead hand modify commit e761cc20946a ("drm/display/dp_mst: Handle old/new payload states in drm_dp_remove_payload()") for the missing contextual changes in 6.1.y in nouveau. I've tested that these work on a Rembrandt laptop connected to WD19TB with two monitors connected.

Fix GPU reset on DCN 3.1.4

by Limonciello, Mario

[Public] Hi, Rajib recently found that GPU reset is failing on DCN 3.1.4 with 6.1.y. It's because of some missing commits in 6.1.y that skip the appropriate functions to match the GPU's graphics architecture. Backporting these and GPU reset works again. Can you please bring these back to 6.1.y and 6.2.y? 2a7798ea7390 ("drm/amdgpu: for S0ix, skip SDMA 5.x+ suspend/resume") e11c775030c5 ("drm/amdgpu: skip psp suspend for IMU enabled ASICs mode2 reset") Thanks,

MST Unplugged during suspend

by Limonciello, Mario

[Public] Hi, There is a bug present in 6.2.y and 6.1.y where if a dock that supports MST is unplugged during suspend it's not possible to get MST working after resume. This is because the cleanup/error path doesn't actually clear the MST tree. It's fixed in 6.3 with: 3f6752b4de41 ("drm/amd/display: Clear MST topology if it fails to resume") Can this please be backported to 6.2.y and 6.1.y? Thanks,

Howlett" <Liam.Howlett(a)oracle.com> Date: Mon, 27 Feb 2023 09:36:06 -0800 Subject: [PATCH] maple_tree: add RCU lock checking to rcu callback functions Dereferencing RCU objects within the RCU callback without the RCU check has caused lockdep to complain. Fix the RCU dereferencing by using the RCU callback lock to ensure the operation is safe. Also stop creating a new lock to use for dereferencing during destruction of the tree or subtree. Instead, pass through a pointer to the tree that has the lock that is held for RCU dereferencing checking. It also does not make sense to use the maple state in the freeing scenario as the tree walk is a special case where the tree no longer has the normal encodings and parent pointers.
