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

This driver supprts hardware monitoring for Analog Devices ADP1050 Digital
Controller for Isolated Power Supply with PMBus interface.

The ADP1050 is an advanced digital controller with a PMBus™
interface targeting high density, high efficiency dc-to-dc power
conversion used to monitor system temperatures, voltages and currents.
Through the PMBus interface, the device can monitor input/output voltages,
input current and temperature.

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.
