dt-bindings: gpio: Convert abilis,tb10x-gpio to DT schema 



Convert the Abilis TB10x GPIO binding to DT schema format. It's a
straight forward conversion.

* Abilis TB10x GPIO controller



Required Properties:

- compatible: Should be "abilis,tb10x-gpio"

- reg: Address and length of the register set for the device

- gpio-controller: Marks the device node as a gpio controller.

- #gpio-cells: Should be <2>. The first cell is the pin number and the

  second cell is used to specify optional parameters:

   - bit 0 specifies polarity (0 for normal, 1 for inverted).

- abilis,ngpio: the number of GPIO pins this driver controls.



Optional Properties:

- interrupt-controller: Marks the device node as an interrupt controller.

- #interrupt-cells: Should be <1>. Interrupts are triggered on both edges.

- interrupts: Defines the interrupt line connecting this GPIO controller to

  its parent interrupt controller.



GPIO ranges are specified as described in

Documentation/devicetree/bindings/gpio/gpio.txt



Example:



	gpioa: gpio@ff140000 {

		compatible = "abilis,tb10x-gpio";

		interrupt-controller;

		#interrupt-cells = <1>;

		interrupt-parent = <&tb10x_ictl>;

		interrupts = <27 2>;

		reg = <0xFF140000 0x1000>;

		gpio-controller;

		#gpio-cells = <2>;

		abilis,ngpio = <3>;

		gpio-ranges = <&iomux 0 0 0>;

		gpio-ranges-group-names = "gpioa_pins";

	};
