Description
|
|
-----------
|
|
|
|
This driver supports hardware monitoring for Flex PIM4328 and
|
|
compatible digital power interface modules.
|
|
|
|
The driver is a client driver to the core PMBus driver. Please see
|
|
Documentation/hwmon/pmbus.rst and Documentation.hwmon/pmbus-core 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.rst for
|
|
details.
