Merge tag 'arm-soc-5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM SoC updates from Arnd Bergmann:
 "One new platform gets added, the Realtek RTD1195, which is an older
  Cortex-a7 based relative of the RTD12xx chips that are already
  supported in arch/arm64. The platform may also be extended to support
  running 32-bit kernels on those 64-bit chips for memory-constrained
  machines.

  In the Renesas shmobile platform, we gain support for "RZ/G1H" or
  R8A7742, an eight-core chip based on Cortex-A15 and Cortex-A7 cores,
  originally released in 2016 as one of the last high-end 32-bit
  designs.

  There is ongoing cleanup for the integrator, tegra, imx, and omap2
  platforms, with integrator getting very close to the goal of having
  zero code in arch/arm/, and omap2 moving more of the chip specifics
  from old board code into device tree files.

  The Versatile Express platform is made more modular, with built-in
  drivers now becoming loadable modules. This is part of a greater
  effort for the Android OS to have a common kernel binary for all
  platforms and any platform specific code in loadable modules.

  The PXA platform drops support for Compulab's pxa2xx boards that had
  rather unusual flash and PCI drivers but no known users remaining. All
  device drivers specific to those boards can now get removed as well.

  Across platforms, there is ongoing cleanup, with Geert and Rob
  revisiting some a lot of Kconfig options"
