Merge tag 'late-mvebu-rebased' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC mvebu platform changes from Olof Johansson:
 "This series contains changes for the Marvell EBU platforms (mvebu,
  orion, kirkwood, dove) that were not part of the first set of pull
  requests because of dependencies on the MMC tree, and being submitted
  a little late.

  Notable changes are:

   - More devices get moved out of board files into device tree
     descriptions.  The remaining devices listed in there have patches
     that will get sent for 3.10, after which we can remove a lot of the
     board files entirely.  We are doing the pinctrl and mmc drivers
     here, ethernet and PCI still remain.

   - SMP support for mvebu is improved with support for the local
     interrupt controller.

   - The Guruplug board file gets replaced with a DT description.

  Unfortunately, the dependency on the MMC tree turned out to be a much
  larger problem than expected, when the MMC maintainer rebased the
  patches in his tree that all of the patches in this branch are based
  on, which caused merge conflicts between the new and old versions of
  those patches.

  To work around the merge conflicts, this branch rebases all patches on
  top of the respective MMC patches that did get merged into 3.9.  The
  patches are all identical to the versions that were part of
  linux-next, but have a new commit date."
