The mach-mxs (i.MX23 and i.MX28) is a totally different sub-architecture
from mach-imx.  Freescale acquired it from SigmaTel a few years back.
These two sub-architectures have completely different pin controllers.
So, no, they are not going to use the same pinctrl driver but two
different ones, pinctrl-mxs and pinctrl-imx.

The only common aspect is both two controllers only supports pin basis
configuration (no hardware pingroup).  I think many other
sub-architectures including omap are same on this aspect.

That's my position too.
