Hm still no ack for dt bindings? We need that for merging.
Also what's the maintainer plan here? Imo best would be to put this
into the drm-misc group maintainer model, with commit rights and all:
https://drm.pages.freedesktop.org/maintainer-tools/drm-misc.html
MAINTAINERS patch to do that would be good.
