| Description |
| ----------- |
| |
| This driver supports hardware monitoring for Analog Devices MAX20860A |
| Step-Down Switching Regulator with PMBus Interface. |
| |
| The MAX20860A is a 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. |
| |
| Usage Notes |
| ----------- |
| |
| This driver does not auto-detect devices. You will have to instantiate |
| the devices explicitly. |
