Pull ARM device-tree updates from Arnd Bergmann:
 "Device-tree continues to see lots of updates. The majority of patches
  here are smaller changes for new hardware on existing platforms, and
  there are a few larger changes worth pointing out.

  New machines:

   - The new Action Semi S500 platform is added along with initial
     support for the LeMaker Guitar board.

   - STM32 gains support for three new boards: stm32h743-disco,
     stm32f746-disco, and stm32f769-disco, along with new device support
     for the existing stm32f429 boards.

   - Renesas adds two new boards, the tiny GR-Peach based on RZ/A1H with
     10MB on-chip SRAM, and the iWave G20D-Q7 System-on-Module plus
     board.

   - On Marvell "mvebu", we gain support for the Linksys WRT3200ACM
     wireless router.

   - For NXP i.MX, we gain support for the Gateworks Ventana GW5600 and
     the Technexion Pico i.MX7D single-board computers.

   - The BeagleBone Blue is added for OMAP, it's the latest variation of
     the popular Beaglebone Black single-board computer.

   - The Allwinner based Lichee Pi Zero and NanoPi M1 Plus boards are
     added, these are the latest variations of a seemingly endless
     supply of similar single-board computers.

  Other updates:

   - Linus Walleij improves support for the "Faraday" based SoC
     platforms from various SoC makers (Moxart, Aspeed, Gemini)

   - The ARM Mali GPU is now describe on Rockchips SoCs

   - Mediatek MT7623 is extended significantly, making it much more
     useful.

   - Lots of individual updates on Renesas, OMAP, Rockchips, Broadcom,
     Allwinner, Qualcomm, iMX

   - For Amlogic, the clock support is extended a lot on meson8b.

   - We now build the devicetree file for the Raspberry Pi 3 on 32-bit
     ARM, in addition to the existing ARM64 support, to help users
     wanting to run a 32-bit system on it"
