  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.
