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

Pull ARM SoC updates from Arnd Bergmann:
 "The updates for arch/arm/mach-* platform code this time are mainly
  minor cleanups.

  Most notably, the DaVinci DM644x/DM646x SoC support gets removed. This
  was also scheduled for later removal early next year, but Linus
  Walleij asked for having them removed earlier to avoid problems for
  the GPIO subsystem"
