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