The touchscreen plane is 4095x4095
your display plane is something like 1920x1080
you need to first scale the touch plane to the display plane with something like

Code:

xinput set-prop 6 152 5.11875 0 0   0 6.825 0   0 0 1
only then can you bother with calibration. I recommend tslib, evdev and libinput did not work for me with ads7846 (as input drivers for Xorg r7)
