Any preference on whether all these go via a platform tree,
or should we pick up the net patch to netdev? I guess taking
the DTB via netdev would be the usual way to handle this?

Supposed dt-bindings go through netdev tree.

without dt-bindings, just DTB_CHECK warning. No strict dependence
relationship between dt-bindings doc and dts file.

Please make it easier for maintainers and sent entirely independent
patches for different subsystems in SEPARATE patchsets.

There is no dependency here between anything. Combining it, OTOH, brings
the questions about such dependency and makes it a bit more difficult to
apply for each maintainer.

Krzysztof

Understand, but without dts change, it is not easy to understand why need
change dt-binding files.

No, it's not.  Taking DTS changes through arch/platform tree is the
usual way.
