-- 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>;
-	};
