Hi Kamil,

many thanks for sending a patch, that looks mostly good from the
technical point of view, only some smaller comments.

But please note that the devicetree needs to go through the Linux
mailing lists and repo first, and we automatically copy it from the
Linux tree once it has been merged there. This is to ensure proper
review and checks with the Linux tooling.

So can you please send just the .dts file to the DT and sunxi
maintainers the respective lists, as reported by get_maintainer.pl?
Then we can take it from there.

Ah, thanks for figuring those out, that's very helpful.

What is "mbox"? Do you have any more information about this vendor?
In any case a new vendor would need to be added to
Documentation/devicetree/bindings/vendor-prefixes.yaml, in a separate
patch. Also you need a patch to add this compatible combination to
Documentation/devicetree/bindings/arm/sunxi.yaml.

Cheers,
Andre
