Kernel driver ibm-cffps

Supported chips:

  • IBM Common Form Factor power supply

Author: Eddie James <eajames@us.ibm.com>

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.
