- reg: integer, I2C address of the fuel gauge.
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>;
};
