From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
Attempt to deal with DP downstream facing ports (DFP) more
thoroughly. This involves reading more of the port caps
and dealing with various clock/bpc limitations.
Also we try to hook up the DP dual mode dongles into the
mix (unfortunately I've not yet seen a DP++ DFP that would
pass the dual mode adapter register i2c accesses through).
And we try to enable YCbCr 444->420 conversion for HDMI DFPs
which could allow some 4k displays to actually use 4k on
pre-icl hardware (which doesn't have native 420 output),
assuming we don't run into some other hardware limits.
It's a bit on the large side but since it looks like other
people are poking around the same area I figured I'd post
the entire thing.
Entire series available here:
