[PATCH v2 1/2] dt-bindings: hwmon: pmbus: Add Analog Devices MAX20860A

[Pradhan, Sanman]

From: Sanman Pradhan <psanman@xxxxxxxxxxx>

Add devicetree binding documentation for the Analog Devices MAX20860A
step-down DC-DC switching regulator with PMBus interface.

Both "adi,max20860a" and "maxim,max20860a" compatible strings are
supported. The MAX20860A was originally manufactured by Maxim Integrated,
now part of Analog Devices.

v2:
  - Added allOf regulator.yaml reference and unevaluatedProperties
  - Added "maxim,max20860a" as alternative compatible
