		Kernel driver lt3074
		====================

		Supported chips:

		* Analog Devices LT3074

		Prefix: 'lt3074'

		Addresses scanned: -

		Datasheet: https://www.analog.com/en/products/lt3074.html

		Authors: Cedric Encarnacion <cedricjustine.encarnacion@analog.com>


		Description
		-----------

		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.

		Usage Notes
		-----------

		This driver does not auto-detect devices. You will have to instantiate
		the devices explicitly. Please see Documentation/i2c/instantiating-devices.rst
		for details.

		Platform data support
		---------------------

		The driver supports standard PMBus driver platform data.
