Description
-----------
This driver implements support for Maxim MAX20710, MAX20730, MAX20734, and MAX20743
Integrated, Step-Down Switching Regulators with PMBus support.
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. Please see Documentation/i2c/instantiating-devices.rst for
details.
