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.

I thought the situation is different as ULP actually already supports generic binding
before that discussion.

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.

So the question is whether it's necessary to switch generic binding back to the
legacy one for ULP. Personally I'm not strongly against this, but I need some
confirmation from Shawn and Sascha.

Shawn & Sascha, would you make a judgement call?
If you also strongly request that, I will try to make it patch to test Linus W.
Hopefully our agreement could satisfy Linus W.
