Merge tag 'dt2-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC DT updates part 2 from Arnd Bergmann:
 "This is a follow-up to the early ARM SoC DT changes, with additional
  content that has external dependencies:

   - The Tegra IOMMU DT support depends on changes from the iommu tree,
     plus the contents of the arm-soc drivers branch
   - The MVEBU PHY support depends on changes from the phy tree
   - The AT91 DT support depends on changes from the RTC and DMA-slave
     trees

  All of these changes just enable additional devices for existing
  platforms"
