Linus?

Any patches welcome.

However we cannot *require* DT for pinctrl to work, there
are archs that do not use DT and these must also be able
to use pinctrl. For example arch/blackfin have expressed
interest IIRC.

Then the question of whether to also support mixed configs
where some callers get data from DT and some from
platform data. I suspect that this is necessary for the
single kernel goal.
