* 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
