Merge tag 'armsoc-late' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC late DT updates from Arnd Bergmann:
 "These updates have been kept in a separate branch mostly because they
  rely on updates to the respective clk drivers to keep the shared
  header files in sync.

   - The Renesas r8a7796 (R-Car M3-W) platform gets added, this is an
     automotive SoC similar to the ⅹ8a7795 chip we already support, but
     the dts changes rely on a clock driver change that has been merged
     for v4.9 through the clk tree.

   - The Amlogic meson-gxbb (S905) platform gains support for a few
     drivers merged through our tree, in particular the network and usb
     driver changes are required and included here, and also the clk
     tree changes.

   - The Allwinner platforms have seen a large-scale change to their clk
     drivers and the dts file updates must come after that. This
     includes the newly added Nextthing GR8 platform, which is derived
     from sun5i/A13.

   - Some integrator (arm32) changes rely on clk driver changes.

   - A single patch for lpc32xx has no such dependency but wasn't added
     until just before the merge window"
