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

Pull ARM SoC DT updates from Olof Johansson:
 "DT changes continue to be the bulk of our merge window contents.

  We continue to have a large set of changes across the board as new
  platforms and drivers are added.

  Some of the new platforms are:
   - Alphascale ASM9260
   - Marvell Armada 388
   - CSR Atlas7
   - TI Davinci DM816x
   - Hisilicon HiP01
   - ST STiH418

  There have also been some sweeping changes, including relicensing of
  DTS contents from GPL to GPLv2+/X11 so that the same files can be
  reused in other non-GPL projects more easily.  There's also been
  changes to the DT Makefile to make it a little less conflict-ridden
  and churny down the road"

+  Freescale DUART is very similar to the PC16552D (and to a
+  pair of NS16550A), albeit with some nonstandard behavior such as
