 36Description
 37-----------
 38
 39This driver supports hardware monitoring 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.
