Converts the device tree bindings for the Actions Semi Owl SoCs DMA
Controller over to YAML schemas.

It also adds new compatible string "actions,s700-dma".

Changes since v4:
	* Added Rob's Reviewed-by tag.
	* Re-order it from 05/10 to 01/10.
Changes since v3:
        * No change.
Changes since v2:
        * Addressed Rob's comments:
           - removed unnecessary description.
           - added unevaluatedProperties
           - added relevant information about
             dma-channels and dma-request
        * Added power-domain property.
Change since v1:
        * Updated the description field to reflect
          only the necessary information.
        * replaced the maxItems field with description for each
          controller attribute(except interrupts).
        * Replaced the clock macro with number to keep the example
          as independent as possible.

My bot found errors running 'make dt_binding_check' on your patch:

/builds/robherring/linux-dt-review/Documentation/devicetree/bindings/dma/owl-dma.example.dt.yaml: example-0: dma-controller@e0260000:reg:0: [0, 3760586752, 0, 4096] is too long


See https://patchwork.ozlabs.org/patch/1321538

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure dt-schema is up to date:

pip3 install git+https://github.com/devicetree-org/dt-schema.git@master --upgrade

Please check and re-submit.

I wasn't able to reproduce it, even after updating the dt-schema.
Kindly have a look at logs:

Looks like, dtschema even after upgrade pointing to older commit "6a941d46b9f5".
Wondering why it has not been pointing to latest commit "6a941d46b9f5"

After upgrading the pip version for python3, and upgrading the dt-schema again
https://pastebin.ubuntu.com/p/Rd9knQgvKH/

Issue is still reproduced.

Thanks

If dtschema is changed, you need a clean tree as make doesn't track
that changing. Specifically, processed-schema-examples.yaml needs to
be removed.

-* Actions Semi Owl SoCs DMA controller
-
-This binding follows the generic DMA bindings defined in dma.txt.
-
-Required properties:
-- compatible: Should be "actions,s900-dma".
-- reg: Should contain DMA registers location and length.
-- interrupts: Should contain 4 interrupts shared by all channel.
-- #dma-cells: Must be <1>. Used to represent the number of integer
-              cells in the dmas property of client device.
-- dma-channels: Physical channels supported.
-- dma-requests: Number of DMA request signals supported by the controller.
-                Refer to Documentation/devicetree/bindings/dma/dma.txt
-- clocks: Phandle and Specifier of the clock feeding the DMA controller.
-
-Example:
-
-Controller:
-                dma: dma-controller@e0260000 {
-                        compatible = "actions,s900-dma";

-
-Client:
-
-DMA clients connected to the Actions Semi Owl SoCs DMA controller must
-use the format described in the dma.txt file, using a two-cell specifier
-for each channel.
-
-The two cells in order are:
-1. A phandle pointing to the DMA controller.
-2. The channel id.
