| 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. |
