- Kernel driver ibm-cffps
- =======================
- 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.
- Sysfs entries
- -------------
