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"
