Dear Sir:
we are using imx6ull for our projects. and face a problem about touch panel.
we have ported the source for a cap touch screen. and I can even get the x/y report value with command "hexdump /dev/input/event1" after click the screen. my lcd is 320X480.
if click left top, it will print
...
0001f10 fc4a 59f6 59e6 0006 0003 0035 0002 0000
0001f20 fc4a 59f6 59e6 0006 0003 0036 002b 0000
...
if click right bottom, it will print
...
0001f90 fcd3 59f6 b731 0001 0003 0035 0115 0000
0001fa0 fcd3 59f6 b731 0001 0003 0036 01df 0000
...
