Hi Krzysztof,

What are the warnings you encountered ?

On my side, i double check and found nothing wrong neither on bindings side nor on source code side:

I previously checked that everything was up to date : 

pip3 install dtschema --upgrade

Then i applied this series https://patchwork.kernel.org/project/linux-arm-kernel/list/?series=957628 
above the current series to check DTB against bindings:
