Can you please rebase it to mainline master or drm-tip?

Hmm. Does
git://github.com/vsyrjala/linux.git dp_downstream_ports_5
work?
Actually better make that dp_downstream_ports_5^^^ aka.
54d846ce62a2 ("drm/i915: Do YCbCr 444->420 conversion via DP protocol
converters") to avoid the experiments and hacks I have sitting on top.
