| 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. | |
