LEGO MINDSTORMS EV3 Battery

~~~~~~~~~~~~~~~~~~~~~~~~~~~



LEGO MINDSTORMS EV3 has some built-in capability for monitoring the battery.

It uses 6 AA batteries or a special Li-ion rechargeable battery pack that is

detected by a key switch in the battery compartment.



Required properties:

 - compatible: Must be "lego,ev3-battery"

 - io-channels: phandles to analog inputs for reading voltage and current

 - io-channel-names: Must be "voltage", "current"

 - rechargeable-gpios: phandle to the rechargeable battery indication gpio



Example:



	battery {

		compatible = "lego,ev3-battery";

		io-channels = <&adc 4>, <&adc 3>;

		io-channel-names = "voltage", "current";

		rechargeable-gpios = <&gpio 136 GPIO_ACTIVE_LOW>;

	};
