-Binding for Qualcomm Atheros AR7xxx/AR9xxx GPIO controller
-
-Required properties:
-- compatible: has to be "qca,<soctype>-gpio" and one of the following
-  fallbacks:
-  - "qca,ar7100-gpio"
-  - "qca,ar9340-gpio"
-- reg: Base address and size of the controllers memory area
-- gpio-controller : Marks the device node as a GPIO controller.
-- #gpio-cells : Should be two. The first cell is the pin number and the
-  second cell is used to specify optional parameters.
-- ngpios: Should be set to the number of GPIOs available on the SoC.
-
-Optional properties:
-- interrupts: Interrupt specifier for the controllers interrupt.
-- interrupt-controller : Identifies the node as an interrupt controller
-- #interrupt-cells : Specifies the number of cells needed to encode interrupt
-		     source, should be 2
-
-Please refer to interrupts.txt in this directory for details of the common
-Interrupt Controllers bindings used by client devices.
-
-Example:
-
-	gpio@...40000 {
-		compatible = "qca,ar9132-gpio", "qca,ar7100-gpio";
-		reg = <0x18040000 0x30>;
-		interrupts = <2>;
-
-		ngpios = <22>;
-
-		gpio-controller;
-		#gpio-cells = <2>;
-
-		interrupt-controller;
-		#interrupt-cells = <2>;
-	};
