1 Kernel driver ibm-cffps
2 =======================
6 * IBM Common Form Factor power supply
8 Author: Eddie James <eajames@us.ibm.com>
13 This driver supports IBM Common Form Factor (CFF) power supplies. This driver
14 is a client to the core PMBus driver.
19 This driver does not auto-detect devices. You will have to instantiate the
20 devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for
26 The following attributes are supported:
