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
[ 1372.528289] ar1021_i2c_irq : X = 1869, Y = 2093, count = 1
