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

yamllint warnings/errors:

dtschema/dtc warnings/errors:
/builds/robherring/linux-dt-review/Documentation/devicetree/bindings/dma/snps,dw-axi-dmac.example.dt.yaml: example-1: dma@28000000:reg:0: [671088640, 4096, 539295744, 36] is too long
	From schema: /usr/local/lib/python3.8/dist-packages/dtschema/schemas/reg.yaml


See https://patchwork.ozlabs.org/patch/1398782

The base for the patch is generally the last rc1. Any dependencies
should be noted.

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

pip3 install dtschema --upgrade

Please check and re-submit.

You need 'minItems: 1' here or everyone has to have 2 entries.

Also, doesn't 'reg' need updating?
