1General Touchscreen Properties:
2
3Optional properties for Touchscreens:
4 - touchscreen-size-x		: horizontal resolution of touchscreen
5				  (in pixels)
6 - touchscreen-size-y		: vertical resolution of touchscreen
7				  (in pixels)
8 - touchscreen-max-pressure	: maximum reported pressure (arbitrary range
9				  dependent on the controller)
10 - touchscreen-min-pressure	: minimum pressure on the touchscreen to be
11				  achieved in order for the touchscreen
12				  driver to report a touch event.
13 - touchscreen-fuzz-x		: horizontal noise value of the absolute input
14				  device (in pixels)
15 - touchscreen-fuzz-y		: vertical noise value of the absolute input
16				  device (in pixels)
17 - touchscreen-fuzz-pressure	: pressure noise value of the absolute input
18				  device (arbitrary range dependent on the
19				  controller)
20 - touchscreen-average-samples : Number of data samples which are averaged
21				  for each read (valid values dependent on the
22				  controller)
23 - touchscreen-inverted-x	: X axis is inverted (boolean)
24 - touchscreen-inverted-y	: Y axis is inverted (boolean)
25 - touchscreen-swapped-x-y	: X and Y axis are swapped (boolean)
26				  Swapping is done after inverting the axis
27 - touchscreen-x-mm		: horizontal length in mm of the touchscreen
28 - touchscreen-y-mm		: vertical length in mm of the touchscreen
