Elantech I2C Touchscreen



Required properties:

- compatible: must be "elan,ekth3500".

- reg: I2C address of the chip.

- interrupts: interrupt to which the chip is connected (see interrupt

  binding[0]).



Optional properties:

- wakeup-source: touchscreen can be used as a wakeup source.

- pinctrl-names: should be "default" (see pinctrl binding [1]).

- pinctrl-0: a phandle pointing to the pin settings for the device (see

  pinctrl binding [1]).

- reset-gpios: reset gpio the chip is connected to.

- vcc33-supply: a phandle for the regulator supplying 3.3V power.

- vccio-supply: a phandle for the regulator supplying IO power.

		/* ... */



		touchscreen@10 {

			compatible = "elan,ekth3500";

			reg = <0x10>;

			interrupt-parent = <&gpio4>;

			interrupts = <0x0 IRQ_TYPE_EDGE_FALLING>;

			wakeup-source;

		};
