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?

https://drm.pages.freedesktop.org/maintainer-tools/getting-started.html

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

Cheers, Daniel

As Daniel wrote this and the next patch is missing a Signed-off-by:
So not applied, but waits for v2 - or that you get commit right and can
do it yourself.

You can add my:
