    +* Ingenic JZ47xx battery bindings
    +
    +Required properties:
    +
    +- compatible: Must be "ingenic,jz4740-battery".
    +- io-channels: phandle and IIO specifier pair to the IIO device.
    + Format described in iio-bindings.txt.
    +- monitored-battery: phandle to a "simple-battery" compatible node.
    +
    +The "monitored-battery" property must be a phandle to a node using the format
    +described in battery.txt, with the following properties being required:
    +
    +- voltage-min-design-microvolt: Drained battery voltage.
    +- voltage-max-design-microvolt: Fully charged battery voltage.
    +
    +Example:
    +
    +#include <dt-bindings/iio/adc/ingenic,adc.h>
    +
    +simple_battery: battery {
    + compatible = "simple-battery";
    + voltage-min-design-microvolt = <3600000>;
    + voltage-max-design-microvolt = <4200000>;
    +};
    +
    +ingenic_battery {
    + compatible = "ingenic,jz4740-battery";
    + io-channels = <&adc INGENIC_ADC_BATTERY>;
    + io-channel-names = "battery";
    + monitored-battery = <&simple_battery>;
    +};
