Supported chips:
* maxim MAX20751
Prefix: 'max20751'
Addresses scanned: -
Application note:
Author: Guenter Roeck <>
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
Platform data support
The driver supports standard PMBus driver platform data.
