Description
|
||
|
|
-----------
|
||
|
|
|
||
|
|
This driver supports hardware montoring for Analog Devices ADM1275 Hot-Swap
|
||
|
|
Controller and Digital Power Monitor.
|
||
|
|
|
||
|
|
The ADM1275 is a hot-swap controller that allows a circuit board to be removed
|
||
|
|
from or inserted into a live backplane. It also features current and voltage
|
||
|
|
readback via an integrated 12-bit analog-to-digital converter (ADC), accessed
|
||
|
|
using a PMBus. interface.
|
||
|
|
|
||
|
|
The driver is a client driver to the core PMBus driver. Please see
|
||
|
|
Documentation/hwmon/pmbus for details on PMBus client drivers.

Usage Notes
|
||
|
|
-----------
|
||
|
|
|
||
|
|
This driver does not auto-detect devices. You will have to instantiate the
|
||
|
|
devices explicitly. Please see Documentation/i2c/instantiating-devices for
|
||
|
|
details.
|
||
|

|
||
|
|
Platform data support
|
||
|
|
---------------------
|
||
|
|
|
||
|
|
The driver supports standard PMBus driver platform data. Please see
|
||
|
|
Documentation/hwmon/pmbus for details.
