=======================
Supported chips:
* IBM Common Form Factor power supply
Author: Eddie James <[email protected]>
Description
-----------
This driver supports IBM Common Form Factor (CFF) power supplies. This driver
is a client to the core PMBus driver.
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.
