+Description
+-----------
+
+This driver supports hardware montoring for National Semiconductor / TI LM25056,
+LM25063, LM25066, LM5064, and LM5066 Power Management, Monitoring, Control, and
+Protection ICs.
+
+The driver is a client driver to the core PMBus driver. Please see
+Documentation/hwmon/pmbus for details on PMBus client drivers.
+
+
+Usage Notes
+-----------
+
+This driver does not auto-detect devices. You will have to instantiate the
+devices explicitly. Please see Documentation/i2c/instantiating-devices for
+details.
+
+
+Platform data support
+---------------------
+
+The driver supports standard PMBus driver platform data.
+
+
+Sysfs entries
