-* 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";
