Merge tag 'soc-arm-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM SoC updates from Arnd Bergmann:
 "These are mostly minor cleanups and bugfixes that address harmless
  problems.

  The largest branch is a conversion of the omap platform to use GPIO
  descriptors throughout the tree, for any devices that are not fully
  converted to devicetree.

  The Samsung Exynos platform gains back support for the Exynos4212 chip
  that was previously unused and removed but is now used for the Samsung
  Galaxy Tab3"
