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

Pull arm-soc Marvell Orion device-tree updates from Olof Johansson:
 "This contains a set of device-tree conversions for Marvell Orion
  platforms that were staged early but took a few tries to get the
  branch into a format where it was suitable for us to pick up.

  Given that most people working on these platforms are hobbyists with
  limited time, we were a bit more flexible with merging it even though
  it came in late."
