Description
-----------

This driver supports hardware monitoring for Analog Devices MAX20860A
Step-Down Switching Regulator with PMBus Interface.

The MAX20860A is a fully integrated step-down DC-DC switching regulator.
Through the PMBus interface, the device can monitor input/output voltages,
output current and temperature.

The driver is a client driver to the core PMBus driver. Please see
Documentation/hwmon/pmbus.rst for details on PMBus client drivers.

Usage Notes
-----------

This driver does not auto-detect devices. You will have to instantiate
the devices explicitly.
