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 Kernel driver pmbus for details on PMBus client drivers.

Usage Notes

This driver does not auto-detect devices. You will have to instantiate the devices explicitly.
