ft6336触摸ic问题

官方给的iic设备地址是0x38,但是i2cdetect出来的是0x48,很奇怪!!!
修改设备树如下

&i2c0 {
	status = "okay";
	focaltech@48{ 
	compatible = "focaltech,fts";	
	reg = <0x48>;  					
	interrupt-parent = <&pio>;				
	interrupts = <1 5 IRQ_TYPE_LEVEL_LOW>;
	focaltech,reset-gpio = <1 3 GPIO_ACTIVE_LOW>; 
	focaltech,irq-gpio = <1 5 IRQ_TYPE_LEVEL_LOW>; 

	focaltech,max-touch-number = <1>;			
	focaltech,display-coords =  <0 0 720 720>;      		
	};

};
&pio {
        fts_irq_pin: fts_irq_pin@0 {
                pins = "PB5";
                function = "gpio_in";
        };
};

目的是用pb5做中断检测,pb3做res

是不是说明gpio没配置对?
还有一句
