Pull ARM/arm64 Devicetree updates from Olof Johansson:
 "As usual, device tree updates is the bulk of our material in this
  merge window. This time around, 559 patches affecting both 32- and
  64-bit platforms.

  Changes are too many to list individually, but some of the larger
  ones:

  New platform/SoC support:

   - Automotive:
     + Renesas R-Car D3 (R8A77995)
     + TI DT76x
     + MediaTek mt2712e
   - Communication-oriented:
     + Qualcomm IPQ8074
     + Broadcom Stingray
     + Marvell Armada 8080
   - Set top box:
     + Uniphier PXs3

  Besides some vendor reference boards for the SoC above, there are also
  several new boards/machines:

   - TI AM335x Moxa UC-8100-ME-T open platform
   - TI AM57xx Beaglebone X15 Rev C
   - Microchip/Atmel sama5d27 SoM1 EK
   - Broadcom Raspberry Pi Zero W
   - Gemini-based D-Link DIR-685 router
   - Freescale i.MX6:
     + Toradex Apalis module + Apalis and Ixora carrier boards
     + Engicam GEAM6UL Starter Kit
   - Freescale i.MX53-based Beckhoff CX9020 Embedded PC
   - Mediatek mt7623-based BananaPi R2
   - Several Allwinner-based single-board computers:
  + Cubietruck plus
  + Bananapi M3, M2M and M64
  + NanoPi A64
  + A64-OLinuXino
  + Pine64
   - Rockchip RK3328 Pine64/Rock64 board support
   - Rockchip RK3399 boards:
  + RK3399 Sapphire module on Excavator carrier (RK3399 reference design)
  + Theobroma Systems RK3399-Q7 SoM
   - ZTE ZX296718 PCBOX Board"
