Hi Dan,

I think NXP has their own SCMI server embedded in TF-A (Peng posted a
link at the public repo a while ago I think...) supporting Pinctrl;
additionally Oleksii/EPAM (the original author of this series) have their
own distinct proprietary SCMI server implementation with Pinctrl (not sure
where it run from in this case but it is a Xen based setup if I remember
right..).

Beside these, there are at least a couple more Vendor proprietary incarnations
of SCMI servers that I am aware of (that most probably did not support Pinctrl
anyway as of now...)

On top of this, on the other side there is, of course, the official SCP/SCMI
server reference implementation, that can live in a number of different places
thanks to the the virtualized environment built by Linaro, but this latter
SCP/SCMI server does not have any official Pinctrl support either as of now.

Thanks,
Cristian
