| 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 | |
| 0ac624f4 | 20 | devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for |
| edd2a4d6 JW |
21 | details. |
