DP_INTF is similar to DPI but does not have the exact same feature set
or register layouts.

DP_INTF is the sink of the display pipeline that is connected to the
DisplayPort controller and encoder unit. It takes the same clocks as
DPI.

Yes, drop this line. I think every patch is reviewed and modified, so
this line is redundant.
