S3/V3S芯片跑Tina 3.5版本的gpio_keys使用

如题,分享一下

sun8iw8p1-pinctrl.dtsi 添加:

			key_pins: key_pins@0 {
				allwinner,pins= "PB12";
				allwinner,function = "gpio_in";
				allwinner,muxsel = <0>;
				allwinner,drive = <1>;
				allwinner,pull = <1>;
			};	

board.dts 添加:

gpio_keys {
	compatible = "gpio-keys";
	pinctrl-names = "default";
	pinctrl-0 = <&key_pins>;
	
	autorepeat;
	button@1 {
			label = "Key home";
			linux,code =  <158>;
			gpios =  <&pio 1 12 6 1 1 1>;
			gpio-key,wakeup;
			//interrupt-parent = <&pio>;
			//interrupts = <1 12 IRQ_TYPE_EDGE_FALLING>; //PB12			
	};
};

好,接着奏乐,接着舞……
