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/media/nxp,imx8mq-vpu.example.dt.yaml: video-codec@...00000: reg: [[942669824, 65536], [942735360, 65536], [942800896, 65536]] is too long
	From schema: /builds/robherring/linux-dt-review/Documentation/devicetree/bindings/media/nxp,imx8mq-vpu.yaml

See https://patchwork.ozlabs.org/patch/1444845

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

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.
