Kernel driver max16601
======================

Supported chips:

  * Maxim MAX16508

    Prefix: 'max16508'

    Addresses scanned: -

    Datasheet: Not published

  * Maxim MAX16601

    Prefix: 'max16601'

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

This driver supports the MAX16508 VR13 Dual-Output Voltage Regulator
as well as the MAX16601 VR13.HC Dual-Output Voltage Regulator chipsets.

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.
