31 Description
32 -----------
33
34 This driver supports hardware montoring for National Semiconductor / TI LM25056,
35 LM25066, LM5064, and LM5064 Power Management, Monitoring, Control, and
36 Protection ICs.
37
38 The driver is a client driver to the core PMBus driver. Please see
39 Documentation/hwmon/pmbus for details on PMBus client drivers.

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