OK I've applied these 21 patches on a branch in the pinctrl
tree to be used as a merge base.

The only valid reason to have it in the pinctrl tree is obviously
that it should be converted into a pinctrl driver in the next
cycle, aiming at includion into kernel v3.9.

I know my colleague Patrice is already working on this, and
thus I can plan for it :-) It is also an interesting subject since
the ux500 will be the first platform with two pin controllers
and the first with an off-SoC pin controller.

But any cleanups are welcome now, and I know you're already
up to more patching...

Let us make sure we chisel out a real nice pinctrl/pinctrl-abx500.c
driver by the end of this kernel cycle so things are under
(pin)control again.

Yours,
Linus Walleij
