   3Required properties:
   4- compatible: must be "cypress,cyapa".
   5- reg: I2C address of the chip.
   6- interrupts: interrupt to which the chip is connected (see interrupt
   7        binding[0]).

   9Optional properties:
  10- wakeup-source: touchpad can be used as a wakeup source.
  11- pinctrl-names: should be "default" (see pinctrl binding [1]).
  12- pinctrl-0: a phandle pointing to the pin settings for the device (see
  13        pinctrl binding [1]).
  14- vcc-supply: a phandle for the regulator supplying 3.3V power.
