Good luck getting these bindings merged. I don't like it as it is pushing
software policy or issues into to the devicetree. What we have as SCMI
binding is more than required for a firmware interface IMO. So, you are
on your own to get these bindings approved as I am not on board with
these but if you convince DT maintainers, I will have a look at it then
to see if we can make that work really.
