+ 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:
-bq27510g3 {
