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.
