13Description
14-----------
15
16This driver supports hardware montoring for Maxim MAX16064 Quad Power-Supply
17Controller with Active-Voltage Output Control and PMBus Interface.
18
19The driver is a client driver to the core PMBus driver.
20Please see Documentation/hwmon/pmbus for details on PMBus client drivers.

23Usage Notes
24-----------
25
26This driver does not auto-detect devices. You will have to instantiate the
27devices explicitly. Please see Documentation/i2c/instantiating-devices for
28details.
