Required properties:
- compatible: should be "gpio-detection"
- status:
- pinctrl-0 : phandle referencing pin configuration of the gpio controller
- pinctrl-names : a pinctrl state named "default" must be defined
- car-reverse : a describtion to show the gpio will be use to car reverse
- car-acc : a describtion to show the gpio will be use to car accelerate
- gpios : The GPIO to set high/low, see "gpios property" in
  Documentation/devicetree/bindings/gpio/gpio.txt. If the pin should be
  low to power down the board set it to "Active Low", otherwise set
  gpio to "Active High".
- linux,debounce-ms: interrupt debounce time. (u32)
- label : The label / name for this partition.  If omitted, the label is taken
- gpio,wakeup : To enable the wakeup comparator in probe

Example:

	gpio_det: gpio-det {
		compatible = "gpio-detection";
		status = "okay";

		pinctrl-0 = <&gpio3_b1 &gpio3_b2>;
		pinctrl-names = "default";
		car-reverse {
			car-reverse-gpios = <&gpio3 10 GPIO_ACTIVE_HIGH>;
			linux,debounce-ms = <5>;
			label = "car-reverse";
			gpio,wakeup;
		};

		car-acc {
			car-acc-gpios = <&gpio3 9 GPIO_ACTIVE_HIGH>;
			linux,debounce-ms = <5>;
			label = "car-acc";
			gpio,wakeup;
		};
	};
