Hi Lukasz,

Thanks for the effort and work on this patchset. The text-based
bindings are slowly converted to JSON-schema but your patches were
developed some time ago and have Rob's review. It would be nice if you
or someone converted it to JSON schema later.
Anyway, I'll pick up everything today evening either for this merge
window or eventually postponed till next one. It is quite late in the
cycle and I want the patches to sit in linux-next for some time.

Best regards,
Krzysztof
