31Description
32-----------
33
Guenter Roeck58615a92013-02-09 15:15:52 -0800[diff] [blame]34This driver supports hardware montoring for National Semiconductor / TI LM25056,
35LM25066, LM5064, and LM5064 Power Management, Monitoring, Control, and
36Protection ICs.
Guenter Roeck03e9bd82011-07-08 10:43:57 -0700[diff] [blame]37
38The driver is a client driver to the core PMBus driver. Please see
39Documentation/hwmon/pmbus for details on PMBus client drivers.

42Usage Notes
43-----------
44
45This driver does not auto-detect devices. You will have to instantiate the
46devices explicitly. Please see Documentation/i2c/instantiating-devices for
47details.
