荔枝派nano电阻触摸使用tsc2007驱动一直触发中断问题

dtsi

i2c0: i2c@1c27000 {
			compatible = "allwinner,sun6i-a31-i2c";
			reg = <0x01c27000 0x400>;
			interrupts = <7>;
			clocks = <&ccu CLK_BUS_I2C0>;
			resets = <&ccu RST_BUS_I2C0>;
			pinctrl-names = "default";
			pinctrl-0 = <&i2c0_pins>;
			status = "disabled";
			#address-cells = <1>;
			#size-cells = <0>;
		};

dts

&i2c0 {
	status = "okay";
	tsc2007@48 {
		compatible = "ti,tsc2007";
		reg = <0x48>;
		interrupt-parent = <&pio>;
		interrupts = <4 10 0x2>;
		gpios = <&pio 4 10 GPIO_ACTIVE_LOW>;
		pendown-gpio = <&pio 4 10 GPIO_ACTIVE_LOW>;
		ti,x-plate-ohms = <660>;
		wakeup-source;
		status = "okay";
	};
};

用了这个命令ts_test发现一直在打印数据，而且那个点也一直在lcd左上角动，然后使用cat /proc/interrupts命令发现居然一直在中断
