We need a sensible binding document to understand those. But at least, shouldn't min-voltage and max-voltage be retrieved as the common regulator binding documented in Documentation/devicetree/bindings/regulator/regulator.txt?
Normally this would be a bad idea as the set of voltages that can safely be used on a given board might differ from those which are supported by the device. However in this case you might be OK as this is all internal to the SoC and so presumably won't vary from board to board.
