[v3] drm/panel: visionox-rm69299: Add backlight support and small fixes

[PATCH v3 0/3] drm/panel: visionox-rm69299: Add backlight support and small fixes

Posted by Guido Günther 5 months ago

This adds optional backlight support via DSI commands. If
a max_brightness is set in the panel description the backlight
is created.

While at that we fold in the already sent out clock fix and
a fix that prevents us from clearing all mode flags when we
only want HS mode.
