# * need ATTRS{name}=="sec_touchscreen" else device not detected as touchscreen
# * give size hint (in mm) otherwise too small size is assumed
# * to avoid palm detection, need LIBINPUT_ATTR_PALM_PRESSURE_THRESHOLD=256
#   and libinput>1.10
# * set calibration matrix for 270 degree clockwise rotation, see [1]
# * remove TOUCHPAD, add TOUCHSCREEN to ensure that device is seen as
#   touchscreen only, see [2]
