Kernel driver crps
==================
Supported chips:
* Intel CRPS185
Prefix: 'crps185'
Addresses scanned: -
Datasheet: Only available under NDA.
Authors:
Ninad Palsule <ninad@linux.ibm.com>
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.
