| * ChipOne icn8318 I2C touchscreen controller | |
| Required properties: | |
| - compatible : "chipone,icn8318" | |
| - reg : I2C slave address of the chip (0x40) | |
| - interrupt-parent : a phandle pointing to the interrupt controller | |
| serving the interrupt for this chip | |
| - interrupts : interrupt specification for the icn8318 interrupt | |
| - wake-gpios : GPIO specification for the WAKE input | |
| - touchscreen-size-x : horizontal resolution of touchscreen (in pixels) | |
| - touchscreen-size-y : vertical resolution of touchscreen (in pixels) | |
| Optional properties: | |
| - pinctrl-names : should be "default" | |
| - pinctrl-0: : a phandle pointing to the pin settings for the | |
| control gpios | |
| - touchscreen-fuzz-x : horizontal noise value of the absolute input | |
| device (in pixels) | |
| - touchscreen-fuzz-y : vertical noise value of the absolute input | |
| device (in pixels) | |
| - touchscreen-inverted-x : X axis is inverted (boolean) | |
| - touchscreen-inverted-y : Y axis is inverted (boolean) | |
| - touchscreen-swapped-x-y : X and Y axis are swapped (boolean) | |
| Swapping is done after inverting the axis | |
