-Mediatek SoC GPIO controller bindings
-
-The IP core used inside these SoCs has 3 banks of 32 GPIOs each.
-The registers of all the banks are interwoven inside one single IO range.
-We load one GPIO controller instance per bank. To make this possible
-we support 2 types of nodes. The parent node defines the memory I/O range and
-has 3 children each describing a single bank. Also the GPIO controller can receive
-interrupts on any of the GPIOs, either edge or level. It then interrupts the CPU
-using GIC INT12.
-
-Required properties for the top level node:
-- compatible:
-  - "mediatek,mt7621-gpio" for Mediatek controllers
-- reg : Physical base address and length of the controller's registers
-- interrupt-parent : phandle of the parent interrupt controller.
-- interrupts : Interrupt specifier for the controllers interrupt.
-- interrupt-controller : Mark the device node as an interrupt controller.
-- #interrupt-cells : Should be 2. The first cell defines the interrupt number.
-   The second cell bits[3:0] is used to specify trigger type as follows:
-	- 1 = low-to-high edge triggered.
-	- 2 = high-to-low edge triggered.
-	- 4 = active high level-sensitive.
-	- 8 = active low level-sensitive.

-
-Required properties for the GPIO bank node:
-- compatible:
-  - "mediatek,mt7621-gpio-bank" for Mediatek banks
-- #gpio-cells : Should be two. The first cell is the GPIO pin number and the
-   second cell specifies GPIO flags, as defined in <dt-bindings/gpio/gpio.h>.
-   Only the GPIO_ACTIVE_HIGH and GPIO_ACTIVE_LOW flags are supported.
-- gpio-controller : Marks the device node as a GPIO controller.
-- reg : The id of the bank that the node describes.

-Example:
-	gpio@600 {
-		#address-cells = <1>;
-		#size-cells = <0>;
-
-		compatible = "mediatek,mt7621-gpio";
-		reg = <0x600 0x100>;
-
-		interrupt-parent = <&gic>;
-		interrupts = <GIC_SHARED 12 IRQ_TYPE_LEVEL_HIGH>;
-		interrupt-controller;
-		#interrupt-cells = <2>;
-
-		gpio0: bank@0 {
-			reg = <0>;
-			compatible = "mediatek,mt7621-gpio-bank";
-			gpio-controller;
-			#gpio-cells = <2>;
-		};
-
-		gpio1: bank@1 {
-			reg = <1>;
-			compatible = "mediatek,mt7621-gpio-bank";
-			gpio-controller;
-			#gpio-cells = <2>;
-		};
-
-		gpio2: bank@2 {
-			reg = <2>;
-			compatible = "mediatek,mt7621-gpio-bank";
-			gpio-controller;
-			#gpio-cells = <2>;
-		};
