  22 +Ilitek ILI210x/ILI251x touchscreen controller
  23 +
  24 +Required properties:
  25 +- compatible:
  26 +    ilitek,ili210x for ILI210x
  27 +    ilitek,ili251x for ILI251x
  28 +
  29 +- reg: The I2C address of the device
  30 +
  31 +- interrupts: The sink for the touchscreen's IRQ output
  32 +    See ../interrupt-controller/interrupts.txt
  33 +
  34 +Optional properties for main touchpad device:
  35 +
  36 +- reset-gpios: GPIO specifier for the touchscreen's reset pin (active low)
  37 +
  38 +Example:
  39 +
  40 +       touchscreen@41 {
  41 +               compatible = "ilitek,ili251x";
  42 +               reg = <0x41>;
  43 +               interrupt-parent = <&gpio4>;
  44 +               interrupts = <7 IRQ_TYPE_EDGE_FALLING>;
  45 +               reset-gpios = <&gpio5 21 GPIO_ACTIVE_LOW>;
  46 +       };
