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 How to instantiate I2C devices for details.
