I do not know what the "maintainers" section in the yaml file is used to indicate. If it is maintainer for the driver then please add the duplicate of what is already in the MAINTAINERS file.

Contains a list of email address(es) for maintainers of this binding. That's the maintainers for the bindings, not the devicetrees consuming them. I belive it makes sense for you guys to maintain it as it has a strong relationship to driver changes. But if you're not interested I'll do it myself. Regards, Nicolas
