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

Pull ARM SoC late DT updates from Arnd Bergmann:
 "This is a collection of a few late fixes and other misc stuff that had
  dependencies on things being merged from other trees.

  The Renesas R-Car power domain handling, and the Nvidia Tegra USB
  support both hand notable changes that required changing the DT
  binding in a way that only provides compatibility with old DT blobs on
  new kernels but not vice versa.  As a consequence, the DT changes are
  based on top of the driver changes and are now in this branch.

  For NXP i.MX and Samsung Exynos, the changes in here depend on other
  changes that got merged through the clk maintainer tree"
