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

This driver supports MAX20751 Multiphase Master with PMBus Interface
and Internal Buck Converter.

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.


Platform data support
---------------------

The driver supports standard PMBus driver platform data.
