25Description
26-----------
27
28This driver supports hardware montoring for National Semiconductor LM25066,
29LM5064, and LM5064 Power Management, Monitoring, Control, and Protection ICs.
30
31The driver is a client driver to the core PMBus driver. Please see
32Documentation/hwmon/pmbus for details on PMBus client drivers.

35Usage Notes
36-----------
37
38This driver does not auto-detect devices. You will have to instantiate the
39devices explicitly. Please see Documentation/i2c/instantiating-devices for
40details.
