1Elantech I2C Touchscreen
2
3Required properties:
4- compatible: must be "elan,ekth3500".
5- reg: I2C address of the chip.
6- interrupts: interrupt to which the chip is connected (see interrupt
7 binding[0]).
8
9Optional properties:
10- wakeup-source: touchscreen 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- reset-gpios: reset gpio the chip is connected to.
15- vcc33-supply: a phandle for the regulator supplying 3.3V power.
16- vccio-supply: a phandle for the regulator supplying IO power.
