-Mediatek MT7621 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. 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:
-- #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.
-- #interrupt-cells : Specifies the number of cells needed to encode an
- interrupt. Should be 2. The first cell defines the interrupt number,
- the second encodes the trigger flags encoded as described in
- Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
-- 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.
-- gpio-controller : Marks the device node as a GPIO controller.

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