Pull ARM SoC DT updates from Arnd Bergmann:
 "The DT branch adds a lot of new stuff for additional SoC and board
  support.  The branch is the largest one and contains 513 out of the
  total 972 non-merge arm-soc changesets for 3.19.

  Most of the changes are about enabling additional on-chip devices for
  existing machines, but there are also an unusual number of new SoC
  types being added this time:

   - AMLogic Meson8
   - ARM Realview in DT mode
   - Allwinner A80
   - Broadcom BCM47081
   - Broadcom Cygnus
   - Freescale LS1021A
   - Freescale Vybrid 500 series
   - Mediatek MT6592, MT8127, MT8135
   - STMicroelectronics STiH410
   - Samsung Exynos4415

  The level of support for the above differs widely, some are just stubs
  with nothing more than CPU, memory and a UART, but others are fairly
  complete.  As usual, these get extended over time.

  There are also many new boards getting added, this is the list of
  model strings that are showing up in new dts files:

   - ARM RealView PB1176
   - Altera SOCFPGA Arria 10
   - Asus RT-N18U (BCM47081)
   - Buffalo WZR-1750DHP (BCM4708)
   - Buffalo WZR-600DHP2 (BCM47081)
   - Cygnus Enterprise Phone (BCM911360_ENTPHN)
   - D-Link DIR-665
   - Google Spring
   - IGEP COM MODULE Rev. G (TI OMAP AM/DM37x)
   - IGEPv2 Rev. F (TI OMAP AM/DM37x)
   - LS1021A QDS Board
   - LS1021A TWR Board
   - LeMaker Banana Pi
   - MarsBoard RK3066
   - MediaTek MT8127 Moose Board
   - MediaTek MT8135 evaluation board
   - Mele M3
   - Merrii A80 Optimus Board
   - Netgear R6300 V2 (BCM4708)
   - Nomadik STN8815NHK
   - NovaTech OrionLXm
   - Olimex A20-OLinuXino-LIME2
   - Raspberry Pi Model B+
   - STiH410 B2120
   - Samsung Monk board
   - Samsung Rinato board
   - Synology DS213j
   - Synology DS414
   - TBS2910 Matrix ARM mini PC
   - TI AM5728 BeagleBoard-X15
   - Toradex Colibri VF50 on Colibri Evaluation Board
   - Zynq ZYBO Development Board

  Other notable changes include:

   - exynos: cleanup of existing dts files
   - mvebu: improved pinctrl support for Armada 370/XP
   - nomadik: restructuring dts files
   - omap: added CAN bus support
   - shmobile: added clock support for some SoCs
   - shmobile: added sound support for some SoCs
   - sirf: reset controller support
   - sunxi: continuing the relicensing under dual GPL/MIT
   - sunxi: lots of new on-chip device support
   - sunxi: working simplefb support (long awaited)
   - various: provide stdout-path property for earlycon"
