Merge branch 'ux500-gpio-pins-for-arm-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson into next/gpio

Linus Walleij <linus.walleij@linaro.org> writes:

 This is a pull request for the GPIO and pin control stuff
 accumulated in the ST-Ericsson tree. Here we have:

 - Improvements and fixes and a custom pin config API from
   Rabin Vincent

 - Device Tree bindings from Lee Jones

 - Some accumulated patches by yours truly.

 - A MSP platform data init patch from Ola Lilja that is merged
   here due to dependency on pin config work. It is to be
   used with work being worked on in parallel in the ALSA
   SoC subsystem.

 If you wonder about the custom pin config implementation this
 is to be used as a transition base as I am rewriting the
 driver to use pinctrl. Expect a final pull request on top
 of this one that will move the ux500 over to pinctrl.

* 'ux500-gpio-pins-for-arm-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson:
  ARM: ux500: Add support for MSP I2S-devices
  drivers/gpio: gpio-nomadik: Add support for irqdomains
  drivers/gpio: gpio-nomadik: Apply Device Tree bindings
  ARM: ux500: update pin handling
  ARM: ux500: implement pin API
  ARM: ux500: remove a bunch of internal pull-ups
  plat-nomadik: new sleep mode pincfg macros
  gpio/nomadik: use ioremap() instead of static mappings
  gpio/nomadik: support low EMI mode
  gpio/nomadik: fix spurious interrupts with SKE
  gpio/nomadik: cache [rf]w?imsc
  gpio/nomadik: don't set SLPM to 1 for non-wakeup pins

Also includes an update to v3.4-rc4.
