Just curious what is eventually connected here? This is possibly a
question for Rob Herring, but I can't figure out how we're supposed to
connect this to the USB type-c connector that is receiving the DP
signal. Does the type-c connector binding support connecting to this end
of the graph? Or should this connect to the DP phy and then the phy
connects to the USB type-c connector node? Right now it is empty which
seems wrong.
