The MDP DT node now contains a list of ports that describe how it connects

MDP.
The GPU phandle is removed too until we figure out what's the right way
to specify it in DT.

The binding doc shouldn't depend on kernel code. You need to document it
here.
Okay. I'll list the available interfaces for each SoC revision.
Thanks,
