| 9 | Description |
| 10 | ----------- |
| 11 | |
| 12 | This driver supports IBM Common Form Factor (CFF) power supplies. This driver |
| 13 | is a client to the core PMBus driver. |
| 14 | |
| 15 | Usage Notes |
| 16 | ----------- |
| 17 | |
| 18 | This driver does not auto-detect devices. You will have to instantiate the |
| 19 | devices explicitly. Please see Documentation/i2c/instantiating-devices for |
| 20 | details. |
