| Description |
| ----------- |
| |
| This driver implements support for Maxim MAX20730, MAX20734, and MAX20743 |
| Integrated, Step-Down Switching Regulators with PMBus support. |
| |
| The driver is a client driver to the core PMBus driver. |
| Please see Documentation/hwmon/pmbus.rst for details on PMBus client drivers. |
