1* SiS I2C Multiple Touch Controller
2
3Required properties:
4- compatible: must be "sis,9200-ts"
5- reg: i2c slave address
6- interrupts: touch controller interrupt (see interrupt
7  binding [0])
8
9Optional properties:
10- pinctrl-names: should be "default" (see pinctrl binding [1]).
11- pinctrl-0: a phandle pointing to the pin settings for the
12  device (see pinctrl binding [1]).
13- attn-gpios: the gpio pin used as attention line
14- reset-gpios: the gpio pin used to reset the controller
15- wakeup-source: touchscreen can be used as a wakeup source
