1 * ChipOne icn8318 I2C touchscreen controller
4 - compatible : "chipone,icn8318"
5 - reg : I2C slave address of the chip (0x40)
6 - interrupt-parent : a phandle pointing to the interrupt controller
7 serving the interrupt for this chip
8 - interrupts : interrupt specification for the icn8318 interrupt
9 - wake-gpios : GPIO specification for the WAKE input
10 - touchscreen-size-x : horizontal resolution of touchscreen (in pixels)
11 - touchscreen-size-y : vertical resolution of touchscreen (in pixels)
14 - pinctrl-names : should be "default"
15 - pinctrl-0: : a phandle pointing to the pin settings for the
17 - touchscreen-fuzz-x : horizontal noise value of the absolute input
19 - touchscreen-fuzz-y : vertical noise value of the absolute input
21 - touchscreen-inverted-x : X axis is inverted (boolean)
22 - touchscreen-inverted-y : Y axis is inverted (boolean)
23 - touchscreen-swapped-x-y : X and Y axis are swapped (boolean)
24 Swapping is done after inverting the axis
