| 14 | Description |
| 15 | ----------- |
| 16 | |
| 17 | This driver supports MAX20751 Multiphase Master with PMBus Interface |
| 18 | and Internal Buck Converter. |
| 19 | |
| 20 | The driver is a client driver to the core PMBus driver. |
| 21 | Please see Documentation/hwmon/pmbus for details on PMBus client drivers. |
| 22 | |
| 23 | |
| 24 | Usage Notes |
| 25 | ----------- |
| 26 | |
| 27 | This driver does not auto-detect devices. You will have to instantiate the |
| 28 | devices explicitly. Please see Documentation/i2c/instantiating-devices for |
| 29 | details. |
