v3: Base on v6.8-rc6, fix yamllint warning
Rob's bot picked the missing `#interrupt-cells` in the example on v2[1]. The
patch was based on v6.8-rc1, and going back over my shell history I missed
the following output from `make dt_binding_check`:
```
...
LINT Documentation/devicetree/bindings
usage: yamllint [-h] [-] [-c CONFIG_FILE | -d CONFIG_DATA] [--list-files] [-f {parsable,standard,colored,github,auto}] [-s] [--no-warnings] [-v] [FILE_OR_DIR ...]
yamllint: error: one of the arguments FILE_OR_DIR - is required
...
```
I've rebased on v6.8-rc6 and no-longer see the issue with the invocation
of `yamllint`.

-Aspeed GPIO controller Device Tree Bindings
--------------------------------------------
-
-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
-- Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
-
- Example:
- gpio@1e780000 {
- #gpio-cells = <2>;
- compatible = "aspeed,ast2400-gpio";
- gpio-controller;
- interrupts = <20>;
- reg = <0x1e780000 0x1000>;
- interrupt-controller;
- };

Where are the constraints I asked? minimum, maximum.

Sorry. Thanks for clarifying. I'll address that in v4.
