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

Pull ARM SoC device-tree updates from Olof Johansson:
 "Part 1 of device-tree updates for 3.10.  The bulk of the churn in this
  branch is due to i.MX moving from C-defined pin control over to device
  tree, which is a one-time conversion that will allow greater
  flexibility down the road.

  Besides that, there's PCI-e bindings for Marvell mvebu platforms and a
  handful of cleanups to tegra due to the new include file functionality
  of the device tree compiler"
