| Description |
| ----------- |
| |
| This driver supports hardware monitoring for Analog Devices MAX20830 |
| Step-Down Switching Regulator with PMBus Interface. |
| |
| The MAX20830 is a 2.7V to 16V, 30A fully integrated step-down DC-DC switching |
| regulator. Through the PMBus interface, the device can monitor input/output |
| voltages, output current and temperature. |
| |
| The driver is a client driver to the core PMBus driver. Please see |
| Documentation/hwmon/pmbus.rst for details on PMBus client drivers. |
