I only know this works well at current next-202511xx, these patches 
we're also in sdm845-mainline downstream repo, but there was multiple 
different patches and hacks for panels and other stuff present, so it's 
hard for me verify that on clean mainline kernel these will work as 
expected (as older mainline versions also need the panel patched etc.)

If you insist, I can append Fixes against when these properties we're or 
weren't introduced (talking about PATCH 3/3 too).
