      Datasheet: http://datasheets.maxim-ic.com/en/ds/MAX8688.pdf
  
  Author: Guenter Roeck <guenter.roeck@ericsson.com>
  
  
  Description
  -----------
  
  This driver supports hardware montoring for Maxim MAX8688 Digital Power-Supply
  Controller/Monitor with PMBus Interface.
  
  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
  -------------
  
  The following attributes are supported. Limits are read-write; all other
  attributes are read-only.
  
  in1_label		"vout1"
  in1_input		Measured voltage. From READ_VOUT register.
  in1_min			Minumum Voltage. From VOUT_UV_WARN_LIMIT register.
  in1_max			Maximum voltage. From VOUT_OV_WARN_LIMIT register.
  in1_lcrit		Critical minumum Voltage. VOUT_UV_FAULT_LIMIT register.
  in1_crit		Critical maximum voltage. From VOUT_OV_FAULT_LIMIT register.
  in1_min_alarm		Voltage low alarm. From VOLTAGE_UV_WARNING status.
  in1_max_alarm		Voltage high alarm. From VOLTAGE_OV_WARNING status.
  in1_lcrit_alarm		Voltage critical low alarm. From VOLTAGE_UV_FAULT status.
  in1_crit_alarm		Voltage critical high alarm. From VOLTAGE_OV_FAULT status.
