  13Description
  14-----------
  15
  16This driver supports hardware montoring for Maxim MAX16064 Quad Power-Supply
  17Controller with Active-Voltage Output Control and PMBus Interface.
  18
  19The driver is a client driver to the core PMBus driver.
  20Please see Documentation/hwmon/pmbus for details on PMBus client drivers.

  23Usage Notes
  24-----------
  25
  26This driver does not auto-detect devices. You will have to instantiate the
  27devices explicitly. Please see Documentation/i2c/instantiating-devices for
  28details.

  40The following attributes are supported. Limits are read-write; all other
  41attributes are read-only.
  42
  43in[1-4]_label           "vout[1-4]"
  44in[1-4]_input           Measured voltage. From READ_VOUT register.
  45in[1-4]_min             Minimum Voltage. From VOUT_UV_WARN_LIMIT register.
  46in[1-4]_max             Maximum voltage. From VOUT_OV_WARN_LIMIT register.
  47in[1-4]_lcrit           Critical minimum Voltage. VOUT_UV_FAULT_LIMIT register.
  48in[1-4]_crit            Critical maximum voltage. From VOUT_OV_FAULT_LIMIT register.
  49in[1-4]_min_alarm       Voltage low alarm. From VOLTAGE_UV_WARNING status.
  50in[1-4]_max_alarm       Voltage high alarm. From VOLTAGE_OV_WARNING status.
  51in[1-4]_lcrit_alarm     Voltage critical low alarm. From VOLTAGE_UV_FAULT status.
  52in[1-4]_crit_alarm      Voltage critical high alarm. From VOLTAGE_OV_FAULT status.
  53in[1-4]_highest         Historical maximum voltage.
  54in[1-4]_reset_history   Write any value to reset history.
  55
  56temp1_input             Measured temperature. From READ_TEMPERATURE_1 register.
  57temp1_max               Maximum temperature. From OT_WARN_LIMIT register.
  58temp1_crit              Critical high temperature. From OT_FAULT_LIMIT register.
  59temp1_max_alarm         Chip temperature high alarm. Set by comparing
  60                        READ_TEMPERATURE_1 with OT_WARN_LIMIT if TEMP_OT_WARNING
  61                        status is set.
  62temp1_crit_alarm        Chip temperature critical high alarm. Set by comparing
  63                        READ_TEMPERATURE_1 with OT_FAULT_LIMIT if TEMP_OT_FAULT
  64                        status is set.
  65temp1_highest           Historical maximum temperature.
  66temp1_reset_history     Write any value to reset history.
