* SiS I2C Multiple Touch Controller
Required properties:
- compatible: must be "sis,9200-ts"
- reg: i2c slave address
- interrupt-parent: the phandle for the interrupt controller
(see interrupt binding [0])
- interrupts: touch controller interrupt (see interrupt
binding [0])
Optional properties:
- 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]).
- attn-gpios: the gpio pin used as attention line
- reset-gpios: the gpio pin used to reset the controller
- wakeup-source: touchscreen can be used as a wakeup source

Example:
sis9255@5c {
compatible = "sis,9200-ts";
reg = <0x5c>;
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_sis>;
interrupt-parent = <&gpio3>;
interrupts = <19 IRQ_TYPE_EDGE_FALLING>;
irq-gpios = <&gpio3 19 GPIO_ACTIVE_LOW>;
reset-gpios = <&gpio2 30 GPIO_ACTIVE_LOW>;
};
