Merge tag 'arm-soc-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull 32-bit ARM SoC updates from Arnd Bergmann:
 "These updates are for platform specific code in arch/arm/, mostly
  fixing minor issues.

  The at91 platform gains support for better power management on the
  lan966 platform and new firmware on the sama5 platform. The mediatek
  soc drivers in turn are enabled for the new mt8195 SoC"
