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

This driver supprts hardware monitoring for Analog Devices ADP1050 Digital
Controller for Isolated Power Supply with PMBus interface.
This driver supports hardware monitoring for Analog Devices ADP1050, ADP1051, and
ADP1055 Digital Controller for Isolated Power Supply with PMBus interface.

The ADP1050 is an advanced digital controller with a PMBus™
The ADP105X 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,
