21Description
22-----------
23
24This driver supprts hardware monitoring for Analog Devices ADP1050 Digital
25Controller for Isolated Power Supply with PMBus interface.
26
27The ADP1050 is an advanced digital controller with a PMBus™
28interface targeting high density, high efficiency dc-to-dc power
29conversion used to monitor system temperatures, voltages and currents.
30Through the PMBus interface, the device can monitor input/output voltages,
31input current and temperature.

33Usage Notes
34-----------
35
36This driver does not auto-detect devices. You will have to instantiate
37the devices explicitly.
38Please see Documentation/i2c/instantiating-devices.rst for details.
