Node names should be generic. See also explanation and list of examples
in DT specification:
https://devicetree-specification.readthedocs.io/en/latest/chapter2-devicetree-basics.html#generic-names-recommendation
So at least regulator prefix or suffix.

Why do you need it?

No underscores in node names.
Are you sure this does not cause `make dtsb_check` warnings?
