This converts Nokia 770 to using real firmware node lookup for GPIOs by
attaching the software nodes describing GPIO controllers to their target
devices.

Kevin told me in person I can take this through the GPIO tree as it already
has all the Acks from Aaro and Janusz. I've queued it for v7.2.

Hi!

Gentle ping, can this be queued now for v7.2?

Thanks,
Bart

Kevin,

I think you offered to queue these patches before, can you take them for v7.2?

Thanks,
Bartosz
