The MDP DT node now contains a list of ports that describe how it connects to external encoder interfaces like DSI and HDMI. These follow the standard of_graph bindings, and allow us to get rid of the 'connectors' phandle that contained a list of all the external encoders connected to MDP.

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

• For MDP4, the output port mappings are:
• Port 0 -> LCDC/LVDS

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, Archit
