2 - compatible: should be "gpio-detection"
3 - status:
4 - pinctrl-0 : phandle referencing pin configuration of the gpio controller
5 - pinctrl-names : a pinctrl state named "default" must be defined
6 - car-reverse : a describtion to show the gpio will be use to car reverse
7 - car-acc : a describtion to show the gpio will be use to car accelerate
8 - gpios : The GPIO to set high/low, see "gpios property" in
12 - linux,debounce-ms: interrupt debounce time. (u32)
13 - label : The label / name for this partition.  If omitted, the label is taken
14 - gpio,wakeup : To enable the wakeup comparator in probe
