I can't really say much about this as pinctrl maintainer other than that
it makes me a bit unhappy that i.MX95 is not using the "default"
SCMI pinctrl bindings.

If the spec allows for this, and NXP Freescale is using it, I will just
have to accept it.

It feels like that's the old NXP Freescale pin controller living on
just hidden behind SCMI, so potentially it should also share code
with the old i.MX pin controller driver. But I think you wrote part of
that driver so you would be the best to ask about that in any case
I think?
