Some applications require Vout to exceed the voltage range that the Vsense pin can detect. This binding definition allows users to define the characteristics of a voltage divider placed between Vout and the Vsense pin for any rail powered by the device. These bindings copy the vout-voltage-divider property defined in the maxim,max20730 bindings schema since it is the best fit for the use case of scaling hwmon PMBus telemetry. The generic voltage-divider property used by many iio drivers was determined to be a poor fit because that schema is tied directly to iio for the purpose of scaling io-channel voltages and the isl68137 driver is not an iio driver.

Turns out it is also documented as "isil,isl68137" in trivial-devices.yaml (together with isil,isl69260). Both are referenced in .dts files. How should that be handled ? Thanks, Guenter
