Yes. It's pushed out and will also be included in linux-next.

It *should* be the other way around. So pdev->dev points to the
original platform device, and thus you have a handle on that in e.g.
board files where the pin controller is defined and thus you can
apply pin configurations from there.

Nobody has ACK:ed it and Stephen and Mark both have
unresolved issue with how this should look.

If the current v5 patch suits your needs, please ACK it on the
mailing list so we know that there are people who like this
solution apart from me.

Yours,
