properties:
  compatible:
    enum:
      - adi,adm1177

  reg:
    maxItems: 1

  avcc-supply:
    description:
      Phandle to the Avcc power supply

  shunt-resistor-micro-ohms:
    description:
      The value of curent sense resistor in microohms. If not provided,
      the current reading and overcurrent alert is disabled.

  adi,shutdown-threshold-microamp:
    description:
      Specifies the current level at which an over current alert occurs.
      If not provided, the overcurrent alert is configured to max ADC range
      based on shunt-resistor-micro-ohms.

  adi,vrange-high-enable:
    description:
      Specifies which internal voltage divider to be used. A 1 selects
      a 7:2 voltage divider while a 0 selects a 14:1 voltage divider.
    type: boolean

required:
  - compatible
  - reg
