Merge tag 'soc-ep93xx-dt-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull SoC update from Arnd Bergmann:
 "Convert ep93xx to devicetree

  This concludes a long journey towards replacing the old board files
  with devictree description on the Cirrus Logic EP93xx platform.

  Nikita Shubin has been working on this for a long time, for details
  see the last post on

    https://lore.kernel.org/lkml/20240909-ep93xx-v12-0-e86ab2423d4b@maquefel.me/"
