Merge tag 'soc-arm-6.17' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM SoC code updates from Arnd Bergmann:
 "Another small set of code changes for the 32-bit Arm platforms, and a
  trivial update to the Kconfig entry for the arm64 TI K3 chip.

  Andrew Davis cleans up the system reset handling, which touches a
  couple of platforms.

  The mediatek platform needs some code changes to support
  multiprocessing in the newly added support for the old mt6572 chip"
