36 Description
37 -----------
39 This driver supports hardware monitoring for National Semiconductor / TI LM25056,
40 LM25063, LM25066, LM5064, and LM5066 Power Management, Monitoring, Control, and
41 Protection ICs.
43 The driver is a client driver to the core PMBus driver. Please see
44 Documentation/hwmon/pmbus for details on PMBus client drivers.
47 Usage Notes
48 -----------
50 This driver does not auto-detect devices. You will have to instantiate the
51 devices explicitly. Please see Documentation/i2c/instantiating-devices for
52 details.
55 Platform data support
56 ---------------------
58 The driver supports standard PMBus driver platform data.
