Add a PMBus driver for the Analog Devices MAX20860A step-down DC-DC switching regulator. The MAX20860A provides monitoring of input/output voltage, output current, and temperature via the PMBus interface using linear data format. Optional regulator support is available via CONFIG_SENSORS_MAX20860A_REGULATOR.

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.
