Following my comments for bindings documentation - I think it is better
to add the address-cells, size-cells and ranges in 4th patch.
Because actually in this patch you are adding just basic support for
SROM controller: for saving and restoring registers. It could be merged
even without the rest of patchset.
Best regards,
