Please read the netdev FAQ. You need to indicates which networking tree this is for in the Subject line, and you need to make use of the correct git tree. You should also have a Fixes: tag, indicating where the issue was introduced.

Running 'make dtbs_check' with the schema in this patch gives the following warnings. Consider if they are expected or the schema is incorrect. These may not be new warnings.
Note that it is not yet a requirement to have 0 warnings for dtbs_check. This will change in the future.

No bugs fixes, no cc-stable. Especially that you break existing devices...

You break the ABI. This isusually not accepted in a regular kernel and even totally not accepted accepted for stable kernel.
