Merge tag 'arm-newsoc-6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM new SoC support from Arnd Bergmann:
 "This adds initial support for two SoC families that have been under
  review for a while. In both cases, the origonal idea was to have a
  minimally functional version, but we ended up leaving out the clk
  drivers that are still under review and will be merged through the
  corresponding subsystem tree.

  The Nuvoton NPCM8xx is a 64-bit Baseboard Management Controller and
  based on the 32-bit NPCM7xx family but is now getting added to
  arch/arm64 as well.

  Sunplus SP7021, also known as Plus1, is a general-purpose
  System-in-Package design based on the 32-bit Cortex-A7 SoC on the main
  chip, plus an I/O chip and memory in the same"
