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;
};
/* ... */
};
