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.
