Yeah, good suggestion.

But as of now, the major issue is Cristian is not happy with adding
a vendor compatible for scmi pinctrl when vendor has its own pinconf map.
So we are stuck on how to support i.MX95 SCMI pinctrl.

Previously Cristian suggested build exclusive for generic scmi pinctrl and
i.MX scmi pinctrl, but this means arm64 generic defconfig will not able
to include both configs.

Do you have any suggestions?

Thanks,
Peng.
