36Description
37-----------
38
39This driver supports hardware montoring for National Semiconductor / TI LM25056,
40LM25063, LM25066, LM5064, and LM5066 Power Management, Monitoring, Control, and
41Protection ICs.
42
43The driver is a client driver to the core PMBus driver. Please see
44Documentation/hwmon/pmbus for details on PMBus client drivers.

47Usage Notes
48-----------
49
50This driver does not auto-detect devices. You will have to instantiate the
51devices explicitly. Please see Documentation/i2c/instantiating-devices for
52details.
