The panel is able to receive commands in LP. The current hack to force backlight commands in HS was due to workaround an incorrect settings on DSI controller that prevents sending LP commands while video out was active.
Remove the hack that forces HS commands.

This and the next are missing your s-o-b line. Also you've done a bunch of gpu patches arlready, want drm-misc commit rights so you can make sure they all do land?

There's tons more docs about how the tooling and process works.
Cheers, Daniel
