      Datasheet: http://datasheets.maxim-ic.com/en/ds/MAX16064.pdf
  
  Author: Guenter Roeck <linux@roeck-us.net>
  
  
  Description
  -----------
  
  This driver supports hardware montoring for Maxim MAX16064 Quad Power-Supply
  Controller with Active-Voltage Output Control and 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.
  
  in[1-4]_label		"vout[1-4]"
  in[1-4]_input		Measured voltage. From READ_VOUT register.
  in[1-4]_min		Minimum Voltage. From VOUT_UV_WARN_LIMIT register.
  in[1-4]_max		Maximum voltage. From VOUT_OV_WARN_LIMIT register.
  in[1-4]_lcrit		Critical minimum Voltage. VOUT_UV_FAULT_LIMIT register.
  in[1-4]_crit		Critical maximum voltage. From VOUT_OV_FAULT_LIMIT register.
  in[1-4]_min_alarm	Voltage low alarm. From VOLTAGE_UV_WARNING status.
  in[1-4]_max_alarm	Voltage high alarm. From VOLTAGE_OV_WARNING status.
  in[1-4]_lcrit_alarm	Voltage critical low alarm. From VOLTAGE_UV_FAULT status.
  in[1-4]_crit_alarm	Voltage critical high alarm. From VOLTAGE_OV_FAULT status.
  in[1-4]_highest		Historical maximum voltage.
  in[1-4]_reset_history	Write any value to reset history.
  
  temp1_input		Measured temperature. From READ_TEMPERATURE_1 register.
  temp1_max		Maximum temperature. From OT_WARN_LIMIT register.
  temp1_crit		Critical high temperature. From OT_FAULT_LIMIT register.
  temp1_max_alarm		Chip temperature high alarm. Set by comparing
  			READ_TEMPERATURE_1 with OT_WARN_LIMIT if TEMP_OT_WARNING
  			status is set.
  temp1_crit_alarm	Chip temperature critical high alarm. Set by comparing
  			READ_TEMPERATURE_1 with OT_FAULT_LIMIT if TEMP_OT_FAULT
  			status is set.
  temp1_highest		Historical maximum temperature.
  temp1_reset_history	Write any value to reset history.
