-* ChipOne icn8318 I2C touchscreen controller
-
-Required properties:
- - compatible : "chipone,icn8318"
- - reg : I2C slave address of the chip (0x40)
- - 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
-
-Example:
-
-i2c@00000000 {
- /* ... */
-
- chipone_icn8318@40 {
- compatible = "chipone,icn8318";
- reg = <0x40>;

- interrupts = <9 IRQ_TYPE_EDGE_FALLING>; /* EINT9 (PG9) */
- pinctrl-names = "default";
- pinctrl-0 = <&ts_wake_pin_p66>;
- wake-gpios = <&pio 1 3 GPIO_ACTIVE_HIGH>; /* PB3 */
- touchscreen-size-x = <800>;
- touchscreen-size-y = <480>;
- touchscreen-inverted-x;
- touchscreen-swapped-x-y;
- };

The ChipOne ICN8318 Touchscreen Controller is supported by Linux thanks to its device tree binding. Now that we have the DT validation in place, let's convert the device tree bindings for that driver over to a YAML schema.
