Thanks for bringing this up again. This is a very crucial bit of
information that somehow needs to be communicated from the panel driver
to the crtc/encoder drivers. I vaguely remember that an earlier attempt
to add this flag to the userspace visible DRM_MODE_FLAGs was met with
resistance before, but I can't find it right now.

regards
Philipp
