hwmon: (pmbus) Add support for MAX20751 MAX20751 is a multiphase power controller with internal buck converter. It uses VR12.0 to report the output voltage. This requires an explicit driver, since the VR version can not be auto-detected. The chip supports a manufacturer specific command to fine-tune the output voltage. This command is not currently supported. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
