|
|
-----------
|
||
|
|
|
||
|
|
This driver supports IBM Common Form Factor (CFF) power supplies. This driver
|
||
|
|
is a client to the core PMBus driver.
|

|
|
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.
