This moves the Nomadik "GPIO" driver to the pinctrl subsystem
and adds the interfaces needed to provide a pinctrl driver for
the DB8500 ASIC.
It further switches Ux500 over to using it with a combination
of hogs and runtime controls.
The ux500 portions were developed on top of the gpio and pins
branch earlier sent for integration in the ARM SoC tree.
Linus Walleij (12):
gpio: move the Nomadik GPIO driver to pinctrl
pinctrl: basic Nomadik pinctrl interface
pinctrl/nomadik: break out single GPIO debug function
pinctrl/nomadik: reuse GPIO debug function for pins
pinctrl/nomadik: implement pin multiplexing
pinctrl/nomadik: implement pin configuration
pinctrl: add sleep state definition
ARM: ux500: switch over to Nomadik pinctrl driver
ARM: ux500: delete custom pin control system
ARM: ux500: switch to using pinctrl for uart0
ARM: ux500: alter MSP registration to return a device pointer
ARM: ux500: switch MSP to using pinctrl for pins

I get build errors with nhk8815_defconfig after this:
arch/arm/mach-nomadik/built-in.o: In function `nhk8815_eth_init':

Here is my suggested fix:
8<-----
ARM: nomadik: enable PINCTRL_NOMADIK where needed
The nomadik gpio code has been converted to pinctrl, but the nomadik platform
still expects the old code to be present. Change it to use the new one instead.

This looks perfect Arnd, thanks for fixing this!

I plan to migrate also the Nomadik to pinctrl and delete the old open-coded
interfaces in the driver for the next kernel cycle.

Ok, applied to next/pinctrl.
On a more general note, how shall we go about merging pinctrl stuff in the
upcoming merge window? We've got a bunch of changes in arm-soc now that depend
on your pinctrl/devel branch, and I want to get as many of my own patches
merged upstream early.
One option would be that you just try to be very early with sending your
branch and arm-soc goes directly after that, another option would be that
we send a pull request for your tree along with the stuff that depends on
it, with your permission.

Sounds good.

Either way is fine with me, I was planning to send a pull request as soon
as the merge window opens anyway. If you need it, I can lock down the
pinctrl tree and prepare the pull tag.

Ok, that's good then. I guess we can just wait until your pull request is
out and put a note in the ones from arm-soc that depend on it.
