Merge tag 'arm-soc-v5.12' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM SoC updates from Arnd Bergmann:
"This is mostly 32-bit code for SoC platforms, and looks smaller than
any such branch I remember from previous kernels, as most of this is
now handled in other subsystems for modern platforms:
- Minor bugfixes and Kconfig updates for Tegra, Broadcom, i.MX,
Renesas, and Samsung
- Updates to the MAINTAINERS listing for Actions, OMAP, and Samsung
- Samsung SoC driver updates to make them loadable modules"
