dt-bindings: input: touchscreen: ilitek_ts_i2c: Absorb ili2xxx bindings 



While Linux uses a different driver, the Ilitek
ILI210x/ILI2117/ILI2120/ILI251x touchscreen controller Device Tree
binding documentation is very similar.

  - Drop the fixed reg value, as some controllers use a different
    address,
  - Make reset-gpios optional, as it is not always wired.

Ilitek ILI210x/ILI2117/ILI2120/ILI251x touchscreen controller



Required properties:

- compatible:

    ilitek,ili210x for ILI210x

    ilitek,ili2117 for ILI2117

    ilitek,ili2120 for ILI2120

    ilitek,ili251x for ILI251x



- reg: The I2C address of the device



- interrupts: The sink for the touchscreen's IRQ output

    See ../interrupt-controller/interrupts.txt



Optional properties for main touchpad device:



- reset-gpios: GPIO specifier for the touchscreen's reset pin (active low)



Example:



	touchscreen@41 {

		compatible = "ilitek,ili251x";

		reg = <0x41>;

		interrupt-parent = <&gpio4>;

		interrupts = <7 IRQ_TYPE_EDGE_FALLING>;

		reset-gpios = <&gpio5 21 GPIO_ACTIVE_LOW>;

	};
