Kernel driver crps
==================

Supported chips:

  * Intel CRPS185

    Prefix: 'crps185'

    Addresses scanned: -

    Datasheet: Only available under NDA.

Authors:

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

This driver implements support for Intel Common Redundant Power supply with
PMBus support.

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.
