Overall am still not able to clear visualize on how MTD bindings with 
nvmem cells would look in both partition and un-partition usecases?
An example DT would be nice here!!    
Something along those lines:  
We must also have a compatible string on the nvmem-cells node to make
sure we don't clash with the old style MTD partitions,
That's not possible, because we don't have a reg prop in the
nvmem-cells node.
or some other
device specific binding.
This one might happen.

Was Rob okay with this compatible? If he was, I guess we can go for
this binding. Srinivas, any objection?
