Kernel driver max16601
======================
Supported chips:
* Maxim MAX16601
Prefix: 'max16601'
Addresses scanned: -
Datasheet: Not published
Author: Guenter Roeck <linux@roeck-us.net>
Description
-----------
This driver supports the MAX16601 VR13.HC Dual-Output Voltage Regulator
Chipset.
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.
