--------------------------------------------

-Required properties:
-- compatible : Either "aspeed,ast2400-gpio", "aspeed,ast2500-gpio",
- or "aspeed,ast2600-gpio".
-
-- #gpio-cells : Should be two
- - First cell is the GPIO line number
- - Second cell is used to specify optional
- parameters (unused)
-
-- reg : Address and length of the register set for the device
-- gpio-controller : Marks the device node as a GPIO controller.
-- interrupts : Interrupt specifier (see interrupt bindings for
- details)
-- interrupt-controller : Mark the GPIO controller as an interrupt-controller
-
-Optional properties:
-
-- clocks : A phandle to the clock to use for debounce timings
-- ngpios : Number of GPIOs controlled by this controller. Should be set
- when there are multiple GPIO controllers on a SoC (ast2600).
-
-The gpio and interrupt properties are further described in their respective
-bindings documentation:
-
-- Documentation/devicetree/bindings/gpio/gpio.txt

-Nomadik GPIO controller
-
-Required properties:
-- compatible : Should be "st,nomadik-gpio".
-- reg : Physical base address and length of the controller's registers.
-- interrupts : The interrupt outputs from the controller.
-- #gpio-cells : Should be two:
- The first cell is the pin number.
- The second cell is used to specify optional parameters:
- - bits[3:0] trigger type and level flags:
- 1 = low-to-high edge triggered.
- 2 = high-to-low edge triggered.
- 4 = active high level-sensitive.
- 8 = active low level-sensitive.
-- gpio-controller : Marks the device node as a GPIO controller.
-- interrupt-controller : Marks the device node as an interrupt controller.
-- gpio-bank : Specifies which bank a controller owns.
-- st,supports-sleepmode : Specifies whether controller can sleep or not
