I'm adding Philipp to Cc, since he is the last one who tested the change
and helped me to push the change to the mainline:
https://lists.freedesktop.org/archives/dri-devel/2016-September/118569.html
The problem is that there is no official DW HDMI bridge maintainer, may be
you can review the change, and if you find it satisfactory push it through
ARM/iMX tree.
