Pull ARM SoC device tree updates from Arnd Bergmann:
 "We get a moderate number of new machines this time, and only one new
  SoC variant (Actions S700):

  Actions:
   - S700 Soc and CubieBoard7 development board
   - Allo.com Sparky Single-board-computer

  Allwinner:
   - Orange Pi R1 development board
   - Libre Computer Board ALL-H3-CC H3 single-board computer

  ASpeed ast2x00:
   - Witherspoon: OpenPower Power9 server manufactured by IBM that uses the ASPEED ast2500
   - Zaius: OpenPower Power9 server manufactured by Invatech that uses the ASPEED ast2500
   - Q71L: Intel Xeon server manufactured by Qanta that uses the ASPEED ast2400

  AT91:
   - Axentia Nattis/Natte digital signage
   - sama5d2 PTC-ek Evaluation board

  Freescale/NXP i.MX:
   - SolidRun Humminboard2 development board
   - Variscite DART-MX6 SoM and Carrier-board
   - Technologic TS-4600 and TS-7970 development board
   - Toradex Colibri iMX7D SoM board
   - v1.5 variant of Solidrun Cubox-i and Hummingboard

  Freescale/NXP Layerscape:
   - Moxa UC-8410A Series industrial computer

  Gemini:
   - D-Link DNS-313 NAS enclosure

  OMAP:
   - LogicPD OMAP35xx SOM-LV devkit
   - LogicPD OMAP35xx Torpedo devkit

  Renesas:
   - r8a77970 (V3M) Starter Kit board
   - r8a7795 (M3-W) Salvator-XS board

  We finally managed to get the dtc warnings under control, with no more
  build-time warnings for bad device tree files. This includes fixes for
  the majority of platforms, including nomadik, samsung, lpc32xx, STi,
  spear, mediatek, freescale, qcom, realview, keystone, omap, kirkwood,
  renesas, hisilicon, and broadcom.

  Files get rearranged on a few platforms, in particular the Marvell
  Armada 7K/8K device tree files are changed in preparation for future
  SoC support, based on more than two of the same chips in one package,
  and some boards get renamed for oxnas for consistency.

  Finally, many existing SoCs gain descriptions for additional on-chip
  devices that we can now support with kernel drivers:

   - Allwinner A83t (drm, ethernet, i2c, ...), H3/H5 (USB-OTG)
   - Amlogic AXG family (clk, pinctrl, pwm, ...), and others (vpu, hdmi)
   - Aspeed clk controller support
   - Freescale LS1088A, LS1021A device support
   - Gemini Ethernet, PCI, TVE, panel
   - Keystone gpio, qspi, more uarts
   - Mediatek cpufreq, regulator, clock, reset
   - Marvell thermal, cpufreq, nand
   - Renesas SMP, thermal, timer, PWM, sound, phy, ipmmu
   - Rockchip Mipi, GPU, display
   - Samsung Exynos5433 PMU, power domain, nfc
   - Spreadtrum: sc9860 clocks
   - Tegra TX2 PSDI, HDMI, I2C,SMMU, display, fuse, ..."
