Description

This driver supports hardware monitoring for Maxim MAX16064 Quad Power-SupplyController with Active-Voltage Output Control and PMBus Interface.

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 thedevices explicitly. Please see Documentation/i2c/instantiating-devices.rst fordetails.

Platform data support

The driver supports standard PMBus driver platform data.
