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

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