  active-semi,input-voltage-threshold-microvolt:
    description: |
      Specifies the charger's input over-voltage threshold value.
      Despite the name, specified values are in millivolt (mV).
      Defaults to 6.6 V

  active-semi,precondition-timeout:
    $ref: /schemas/types.yaml#/definitions/uint32
    description: |
      Specifies the charger's PRECONDITION safety timer setting value in minutes.
      If 0, it means to disable this timer.
      Defaults to 40 minutes.
    enum: [ 0, 40, 60, 80 ]

  active-semi,total-timeout:

    description: |
      Specifies the charger's total safety timer setting value in hours;
      If 0, it means to disable this timer;
      Defaults to 3 hours.
