This patch series is about the proposal of Armada8K's reset controller
dt-binding. The dt-bindings issues of clock/GPIO controllers have been
there for years. Having to say, it is not just a simple patch to fix it. It
will require to convert the dt-binding document into json schemas as
well as adapt these dt changes in the drivers. So I would suggest to
fixing it in later patches. How do you think about it?
