| * 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 |
