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

This driver supports hardware monitoring for Analog Devices MAX17616/MAX17616A
Current-Limiter with OV/Surge, UV, Reverse Polarity, Loss of Ground Protection
with PMBus Interface.

The MAX17616/MAX17616A is a 3V to 80V, 7A current-limiter with overvoltage,
surge, undervoltage, reverse polarity, and loss of ground protection. Through
the PMBus interface, the device can monitor input/output voltages, output current
and temperature.

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.
