So this is for the situation where some machines have pinctrl and some haven't.

And I think that's how some archs have used the regulator dummies earlier,
so I clearly see the point. So if converting a subset of machines in an
architecture you will need this for a transitional period.

Is this helpful to get i.MX support in place?

On one hand I'd say we merge it for that reason alone, instead of requiring
all i.MX machines to be converted at once.

On the other hand, I fear that this will be used to avoid *ever* migrating
the old machines to pinctrl. And it's a generic disease that people working
in the arch/arm/* tree want to ditch old hardware without actually deleting
the code.

I'd like Sascha's view on this to make a good decision.
