| Description |
| ----------- |
| |
| This driver supports MAX20751 Multiphase Master with PMBus Interface |
| and Internal Buck Converter. |
| |
| The driver is a client driver to the core PMBus driver. |
| Please see Documentation/hwmon/pmbus.rst for details on PMBus client drivers. |
| |
| |
| Usage Notes |
| ----------- |
| |
| This driver does not auto-detect devices. You will have to instantiate the |
| devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for |
| details. |
| |
| |
| Platform data support |
| --------------------- |
| |
