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>; };
