      phandle to a "simple-battery" compatible node.

      This property must be a phandle to a node using the format described
      in battery.yaml, with the following properties being required:
      - voltage-min-design-microvolt: drained battery voltage,
      - voltage-max-design-microvolt: fully charged battery voltage.

required:
  - compatible
  - io-channels
  - io-channel-names
  - monitored-battery
