Merge tag 'arm-soc-5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM SoC updates from Arnd Bergmann:
 "These are mostly cosmetic changes and minor bugfixes for the SoC
  specific code, across the 32-bit at91, mvebu, davinci, samsung, and
  omap platforms.

  The main notable changes are for the Samsung Exynos platform, which
  sees a rewrite of gpio handling and a change to restore and adds a
  workaround for a problem with cpuidle support"
