This is a note to let you know that I've just added the patch titled
drm/amd/display: Pass pwrseq inst for backlight and ABM
to the 6.6-stable tree which can be found at:
http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary
The filename of the patch is:
drm-amd-display-pass-pwrseq-inst-for-backlight-and-abm.patch
and it can be found in the queue-6.6 subdirectory.
If you, or anyone else, feels it should not be added to the stable tree,
please let <stable@xxxxxxxxxxxxxxx> know about it.

Subject: drm/amd/display: Pass pwrseq inst for backlight and ABM
From: Lewis Huang <lewis.huang@xxxxxxx>
commit b17ef04bf3a4346d66404454d6a646343ddc9749 upstream.
[Why]
OTG inst and pwrseq inst mapping is not align therefore we cannot use
otg_inst as pwrseq inst to get DCIO register.
[How]
1. Pass the correct pwrseq instance to dmub when set abm pipe.
2. LVTMA control index change from panel_inst to pwrseq_inst.
