Not sure what you mean by "that's ruled out". Anyways, to be clear,
the bindings must remain same as long as the h/w doesn't change. It is
the client driver (DT node) that should be versioned for SCPI or SCMI
based on what the platform supports.

I have tried many ways to explain how to implement it and apparently
failed. So lets talk code.
You have already shared this "v2" MHU driver, now please also share
your client driver. I'll make it work with original MHU driver and
that should settle your confusion.

Thanks.
