| 10 | Description |
| 11 | ----------- |
| 12 | |
| 13 | This driver supports Inspur Power System power supplies. This driver |
| 14 | is a client to the core PMBus driver. |
| 15 | |
| 16 | Usage Notes |
| 17 | ----------- |
| 18 | |
| 19 | This driver does not auto-detect devices. You will have to instantiate the |
