| 35 | Description |
| 36 | ----------- |
| 37 | |
| 38 | This driver implements support for Maxim MAX20730, MAX20734, and MAX20743 |
| 39 | Integrated, Step-Down Switching Regulators with PMBus support. |
| 40 | |
| 41 | The driver is a client driver to the core PMBus driver. |
| 42 | Please see Documentation/hwmon/pmbus.rst for details on PMBus client drivers. |
| 43 | |
| 44 | |
| 45 | Usage Notes |
| 46 | ----------- |
| 47 | |
| 48 | This driver does not auto-detect devices. You will have to instantiate the |
| 49 | devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for |
| 50 | details. |
