Is there any code in their kernel which varies the supply voltages?  If
there isn't then simply omitting the voltage ranges is the best option,
leaving the supplies fixed.  If there is then the range it uses is a
good starting point.  In general supplies will be fixed voltage on a
given board unless there is a specific reason to vary them.

This compatible isn't part of the driver.
