36	Description
37	-----------
38	
39	This driver supports hardware montoring for National Semiconductor / TI LM25056,
40	LM25063, LM25066, LM5064, and LM5066 Power Management, Monitoring, Control, and
41	Protection ICs.
42	
43	The driver is a client driver to the core PMBus driver. Please see
44	Documentation/hwmon/pmbus for details on PMBus client drivers.
45	
46	
47	Usage Notes
48	-----------
49	
50	This driver does not auto-detect devices. You will have to instantiate the
51	devices explicitly. Please see Documentation/i2c/instantiating-devices for
52	details.
53	
54	
55	Platform data support
56	---------------------
57	
58	The driver supports standard PMBus driver platform data.
59	
60	
61	Sysfs entries
