This driver supports hardware monitoring for Analog Devices LT3074 Linear Regulator with PMBus interface.
The LT3074 is a low voltage, ultra-low noise and ultra-fast transient response linear regulator with PMBus serial interface. PMBus telemetry feature provides information regarding the output voltage and current, input voltage, bias voltage and die temperature.
The driver is a client driver to the core PMBus driver. Please see Documentation/hwmon/pmbus.rst for details on PMBus client drivers.
This driver does not auto-detect devices. You will have to instantiate the devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for details.
The driver supports standard PMBus driver platform data.
