| 43 | Description | |
| 44 | ----------- | |
| 45 | ||
| 5c9353f5 | 46 | This driver implements support for Maxim MAX20710, MAX20730, MAX20734, and MAX20743 |
| cce20958 GR |
47 | Integrated, Step-Down Switching Regulators with PMBus support. |
| 48 | ||
| 49 | The driver is a client driver to the core PMBus driver. | |
| 50 | Please see Documentation/hwmon/pmbus.rst for details on PMBus client drivers. | |
| 51 | ||
| 52 | ||
| 53 | Usage Notes | |
| 54 | ----------- | |
| 55 | ||
| 56 | This driver does not auto-detect devices. You will have to instantiate the | |
| 57 | devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for | |
| 58 | details. | |
