+Hisilicon Hi6220 GPIO controller bindings
+
+Required properties:
+ - compatible: "arm,pl061","arm,primecell"
+ - gpio-controller: Marks the device node as a GPIO controller.
+ - #gpio-cells: Should be 2. See gpio.txt in this directory for a
+ description of the cells format.
+ - interrupt-controller: Mark the device node as an interrupt controller
+
+Example:
+
+ gpio0: gpio@...11000 {
+ compatible = "arm,pl061", "arm,primecell";
+ reg = <0x0 0xf8011000 0x0 0x1000>;
+ interrupts = <0 52 0x4>;
+ gpio-controller;
+ #gpio-cells = <2>;
+ interrupt-controller;
+ #interrupt-cells = <2>;
+ clocks = <&ao_ctrl 2>;
+ clock-names = "apb_pclk";
+ status = "ok";
+ };
