-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.
