| 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. | |
