Merge tag 'soc-arm-6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM SoC updates from Arnd Bergmann:
 "The Oxford Semiconductor OX810/OX820 'Oxnas' platform gets retired
  after the ARM11MPcore processor keeps causing problems in certain
  corner cases. OX820 was the only remaining SoC with this core after
  CNS3xxx got retired, and its driver support was never completely
  merged upstream. The Arm 'Realview' reference platform still supports
  ARM11MPCore in principle, but this was never a product, and the CPU
  support will get cleaned up later on.

  Another series updates the mv78xx0 platform, which has been similarly
  neglected for a while, but should work properly again now.

  The other changes are minor cleanups across platforms, mostly
  converting code to more modern interfaces for DT nodes and removing
  some more code as a follow-up to the large-scale platform removal in
  linux-6.3"
