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

This driver supports hardware monitoring for Analog Devices MAX20830
Step-Down Switching Regulator with PMBus Interface.

The MAX20830 is a 2.7V to 16V, 30A 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.
