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

This driver supports hardware monitoring for Analog Devices MAX20830, MAX20830C
and MAX20840C. These are Step-Down Switching Regulator with PMBus Interface.

MAX20830, and MAX20830C are 2.7V to 16V, 30A fully integrated step-down DC-DC
switching regulators. MAX20840C is similar but can reach 40A. Through the PMBus
interface, these devices 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.
