rk3288主板,关于电阻屏触控问题请教

当前现象:已经加入触控芯片AR1021(I2C接口)的驱动, 使用板子的GPIO7_A6作为中断IO,芯片数据引脚使用的是板子的I2C1, 现在在后台终端使用 cat /dev/inout/event0 然后点击触控屏,中断有输出, 但是android系统界面没有任何响应
请问这是什么问题呢

使用tslib校准时,执行ts_calibrate 提示
oading module linear
__ts_load_module_static:-------139
__ts_load_module:-------233
__ts_load_module:-------237
xres = 1366, yres = 768
tslib: Selected device is not a touchscreen (must support ABS event type)
环境变量都是设置对了的,点击触控屏也是有输出的(在驱动中加入了打印信息),如下
