+Description
|
|
|
+-----------
|
|
|
+
|
|
|
+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 for
|
|
|
+details.
