Merge branch 'ux500-devicetree-for-arm-soc' of... 

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

From: Linus Walleij <linus.walleij@linaro.org>:
  Four core patches paving the way for device tree enablement
  of the Snowball and ux500 at large by Lee Jones.

* 'ux500-devicetree-for-arm-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson

:
  ARM: ux500: Enable PRCMU Timer 4 (clocksource) for Device Tree
  ARM: ux500: Disable SMSC911x platform code registration when DT is enabled
  ARM: ux500: Fork cpu-db8500 platform_devs for sequential DT enablement
  ARM: ux500: Do not attempt to register non-existent i2c devices on Snowball
