  25 Description
  26 -----------
  27
  28 This driver supports hardware montoring for National Semiconductor LM25066,
  29 LM5064, and LM5064 Power Management, Monitoring, Control, and Protection ICs.
  30
  31 The driver is a client driver to the core PMBus driver. Please see
  32 Documentation/hwmon/pmbus for details on PMBus client drivers.

  35 Usage Notes
  36 -----------
  37
  38 This driver does not auto-detect devices. You will have to instantiate the
  39 devices explicitly. Please see Documentation/i2c/instantiating-devices for
  40 details.
