IMX6ULL按键1正常，按键2多次触发

按键1按下触发一次中断，按键按下却触发两次，不知道为什么，有大佬解答一下吗？
设备树按键节点

mykeys {
            compatible = "my_keys";
            mykey1{
                pinctrl-names = "default";
                pinctrl-0 = <&key1_pinctrl>;
                status = "okay";
                key-gpios = <&gpio5 1 GPIO_ACTIVE_HIGH>;
                interrupt-parent = <&gpio5>;
                interrupts = <1 IRQ_TYPE_EDGE_FALLING>;
            };
 
            mykey2{
                pinctrl-names = "default";
                pinctrl-0 = <&key2_pinctrl>;
                status = "okay";
                key-gpios = <&gpio4 14 GPIO_ACTIVE_HIGH>;
                interrupt-parent = <&gpio4>;
                interrupts = <14 IRQ_TYPE_EDGE_FALLING>;
            };
 };

pinctrl部分

&iomuxc {
……
    key2_pinctrl:mykey2{
                fsl,pins = <
                    MX6UL_PAD_NAND_CE1_B__GPIO4_IO14           0x000110A0
                >;
            };
……
}
&iomuxc_snvs {
……
    key1_pinctrl:mykey1{
                fsl,pins = <
                MX6ULL_PAD_SNVS_TAMPER1__GPIO5_IO01     0x000190A0
                >;
            };
……
}

probe函数

static int gpio_key_probe(struct platform_device *pdev)
{
	printk("%s %s line %d\n", __FILE__, __FUNCTION__, __LINE__);
	int i,err;
	struct device_node *node = pdev->dev.of_node;
	count = device_get_child_node_count(&pdev->dev);
	my_keys = kzalloc(sizeof(struct my_keys_gpiod) * count, GFP_KERNEL);
	for(i=0;i<count;i++)
	{
		child_fw = of_get_next_child(node, child_fw);
		if(child_fw)
		{
			my_keys[i].key_gpio = of_get_named_gpio(child_fw,"key-gpios",0);
			if(my_keys[i].key_gpio)
			{
				err = gpio_request(my_keys[i].key_gpio, "key");
				if (err < 0)
				{
					printk("gpio_request is error \n");
					return -1;
				}
			}
			else
			{
				printk("of_get_named_gpio is error \n");
				return -1;
			}
			gpio_direction_input(my_keys[i].key_gpio);
			my_keys[i].key_gpiod = gpio_to_desc(my_keys[i].key_gpio);
			err = request_irq(my_keys[i].irq, gpio_key_isr, IRQF_TRIGGER_FALLING, "my_gpio_key",&my_keys[i] );
			if(err != 0) {
				dev_err(&pdev->dev, "Faikey to request IRQ for key\n");
				return err;	
			}
		}
	}
	return 0;
}

按键1正常，按键2还是会两次触发。
大佬帮我看看啥问题，感谢感谢
