Optional properties:

  • monitored-battery: phandle of battery characteristics node
    The fuel gauge uses the following battery properties:
    • energy-full-design-microwatt-hours
    • charge-full-design-microamp-hours
    • voltage-min-design-microvolt
      Both or neither of the -full-design--hours properties must be set.
      See Documentation/devicetree/bindings/power/supply/battery.txt

Example:

bat: battery {
    compatible = "simple-battery";
    voltage-min-design-microvolt = <3200000>;
    energy-full-design-microwatt-hours = <5290000>;
    charge-full-design-microamp-hours = <1430000>;
};

bq27510g3: fuel-gauge@55 {
    compatible = "ti,bq27510g3";
    reg = <0x55>;
    monitored-battery = <&bat>;
};
