I'm a bit hesitate to do that as the driver already supports it. There's no extra effort
to use it. And we probably could take ULP as a special case to test generic binding
rather then simply drop it and drop driver features. Once we get objection from users
later, we still can simply fallback as there's still only official boards using it.

We had this same discussion some months ago when we were reviewing
i.MX8 support.

I don't see the value in doing pinctrl differently on i.MX7ULP.

Last, it's not correct that there's not only one method for all i.MX devices.
MX23/28 are different ones and ULP is more like MX23/28.
And I saw no objections from users for MX23/28.

Yes, but these are legacy platforms.

For new ones, we should try to keep consistency, just like we
discussed during i.MX8 review.
