mxt224: TOUCH: Calibrate touchscreen
Touchscreen calibration data. This allows the user to go to the edges of the
screen while maintaining a good linearity and touch response.
This change utilizes the clipping feature of mXT224 for better linearity.
Improved sensitivity and made separate fingers more distinguishable.
'Merge threshold' value is adjusted to prevent the problem separating
a wide object into multiple touches. It is changed from 4 to 14.
