LCD Actron Touch with  Driver HY463X

if configure as a multi touch it is not working

Add IDC file in below directory with XY Orientation 

Create idc file along with your touch driver name ie hy46xx_ts.idc

file contant should be

touch.deviceType = touchScreen
touch.orientationAware = 1

touch.size.calibration = none
touch.orientation.calibration = none

Place the idc file in system/usr/idc/

Hopefully it works!

Warm Regards,
