Hi Peng,

I see that you are really starting to like vendor extensions
capabilities :P ... jokes apart I'll have a deeper look at this in the
next days (togetehr with your other pending patches...), BUT in the
meantime a quick one...where are the bindings for these additional
vendor protocols...seems like a patch is missing to add those in

 Documentation/devicetree/bindings/firmware/nxp,imx95-scmi.yaml

...even if bare simple protocol numbers (like existing protocol@81)
currently these are needed for the protocol to be initialized by the
core.

Thanks,
Cristian
