Add support for ADP1050 Digital Controller for Isolated Power Supplies with PMBus interface Voltage, Current and Temperature Monitor. The ADP1050 implements several features to enable a robust system of parallel and redundant operation for customers who require high availability. The device can measure voltage, current and temperature that can be used in different techniques to identify and safely shut down an erroneous power supply in parallel operation mode.

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.
