So as I said before, I'm following Rob Herring's input on this and 
Krzysztof has given RB for this binding. At this stage, I don't see 
scope to change it.

Adding endpoints was already a compromise to address your feedback, 
which I hoped would bring you on board with the design.

There are several SoC bindings as well as new CPHY features which are 
gated on these changes.

Vinod, Kishon I'd request to merge the changes as-is.
