Merge tag 'arm-soc-5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM SoC updates from Olof Johansson:
 "A few SoC (code) changes have queued up this cycle, mostly for minor
  changes and some refactoring and cleanup of legacy platforms. This
  branch also contains a few of the fixes that weren't sent in by the
  end of the release (all fairly minor).

   - Adding an additional maintainer for the TEE subsystem (Sumit Garg)

   - Quite a significant modernization of the IXP4xx platforms by Linus
     Walleij, revisiting with a new PCI host driver/binding, removing
     legacy mach/* include dependencies and moving platform
     detection/config to drivers/soc. Also some updates/cleanup of
     platform data.

   - Core power domain support for Tegra platforms, and some
     improvements in build test coverage by adding stubs for compile
     test targets.

   - A handful of updates to i.MX platforms, adding legacy (non-PSCI)
     SMP support on i.MX7D, SoC ID setup for i.MX50, removal of platform
     data and board fixups for iMX6/7.

  ... and a few smaller changes and fixes for Samsung, OMAP, Allwinner,
  Rockchip"
