Cypress I2C Touchpad

Required properties:

- compatible: must be "cypress,cyapa".

- reg: I2C address of the chip.

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

	binding[0]).

Optional properties:

- wakeup-source: touchpad 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]).

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

Example:

	&i2c0 {

		/* ... */

		/* Cypress Gen3 touchpad */

		touchpad@67 {

			compatible = "cypress,cyapa";

			reg = <0x67>;

			interrupt-parent = <&gpio>;

			interrupts = <2 IRQ_TYPE_EDGE_FALLING>;	/* GPIO 2 */

			wakeup-source;

		};

		/* Cypress Gen5 and later touchpad */

		touchpad@24 {

			compatible = "cypress,cyapa";

			reg = <0x24>;

			interrupt-parent = <&gpio>;

			interrupts = <2 IRQ_TYPE_EDGE_FALLING>;	/* GPIO 2 */

			wakeup-source;

		};

		/* ... */

	};
