Merge tag 'soc-arm-7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull arm SoC code updates from Arnd Bergmann:
 "The largest addition here is the revived support for the ZTE ZX SoC
  platform, though this mostly documentation.

  The other changes are code cleanups that deal with continued
  conversion of the GPIO library away from GPIO numbers to descriptors
  and a few minor bugfixes"
