Idea is good though one note on this is that the DT binding is very Linux-specific and there is a move away from OS-specific bindings. You'll have to repost to a wider audience including the new DT binding maintainers to get their input. You also need to add the binding to Documentation/devicetree/bindings regardless of what the final binding is.
