Merge tag 'drivers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC driver specific changes from Arnd Bergmann:
 "These changes are all driver specific and cross over between arm-soc
  contents and some other subsystem, in these cases cpufreq, crypto,
  dma, pinctrl, mailbox and usb, and the subsystem owners agreed to have
  these changes merged through arm-soc.

  As we proceed to untangle the dependencies between platform code and
  driver code, the amount of changes in this category is fortunately
  shrinking, for 3.11 we have 16 branches here and 101 non-merge
  changesets, the majority of which are for the stedma40 dma engine
  driver used in the ux500 platform.  Cleaning up that code touches
  multiple subsystems, but gets rid of the dependency in the end.

  The mailbox code moved out from mach-omap2 to drivers/mailbox is an
  intermediate step and is still omap specific at the moment.  Patches
  exist to generalize the subsystem and add other drivers with the same
  API, but those did not make it for 3.11."
