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

||
|
|
devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for
|
||
|
|
details.
