Description
-----------
This driver supports hardware montoring for National Semiconductor LM25066,
LM5064, and LM5064 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.
