Pull ARM DT updates from Olof Johansson:
 "Ladies and gentlemen, we proudly announce to you the latest branch of
  ARM device tree contents for the mainline kernel.  Come and see, come
  and see!

  No less than twentythree thousand lines of additions! Just imagine the
  joy you will have of using your mainline kernel on newly supported
  hardware such as Rockchip Chromebooks, Freescale i.MX6UL boards or
  UniPhier hardware!

  For those of you feeling less adventurous, added hardware support on
  platforms such as TI DM814x and Gumstix Overo platforms might be more
  of your liking.

  We've got something for everyone here!

  Ahem.  Cough.  So, anyway...

  This is the usual large batch of DT updates.  Lots and lots of smaller
  changes, some of the larger ones to point out are:

   - Rockchip veyron (Chromebook) support, as well as several other new boards
   - DRM support on Atmel AT91SAM9N12EK
   - USB additions on some Allwinner platforms
   - Mediatek MT6580 support
   - Freescale i.MX6UL support
   - cleanups for Renesas shmobile platforms
   - lots of added devices on LPC18xx
   - lots of added devices and boards on UniPhier

  There's also some dependent code added here, in particular some
  branches that are primarily merged through the clock tree"
