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

  42
  43 in[1-4]_label           "vout[1-4]"
  44 in[1-4]_input           Measured voltage. From READ_VOUT register.
  45 in[1-4]_min             Minimum Voltage. From VOUT_UV_WARN_LIMIT register.
  46 in[1-4]_max             Maximum voltage. From VOUT_OV_WARN_LIMIT register.
  47 in[1-4]_lcrit           Critical minimum Voltage. VOUT_UV_FAULT_LIMIT register.
  48 in[1-4]_crit            Critical maximum voltage. From VOUT_OV_FAULT_LIMIT register.
  49 in[1-4]_min_alarm       Voltage low alarm. From VOLTAGE_UV_WARNING status.
  50 in[1-4]_max_alarm       Voltage high alarm. From VOLTAGE_OV_WARNING status.
  51 in[1-4]_lcrit_alarm     Voltage critical low alarm. From VOLTAGE_UV_FAULT status.
  52 in[1-4]_crit_alarm      Voltage critical high alarm. From VOLTAGE_OV_FAULT status.
  53 in[1-4]_highest         Historical maximum voltage.
  54 in[1-4]_reset_history   Write any value to reset history.
  55
  56 temp1_input             Measured temperature. From READ_TEMPERATURE_1 register.
  57 temp1_max               Maximum temperature. From OT_WARN_LIMIT register.
  58 temp1_crit              Critical high temperature. From OT_FAULT_LIMIT register.
  59 temp1_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.
  62 temp1_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.
  65 temp1_highest           Historical maximum temperature.
  66 temp1_reset_history     Write any value to reset history.
