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

Pull SoC ARM platform updates from Arnd Bergmann:
 "Most of these updates are for removing dead code on the Samsung S3C,
  NXP i.MX, TI OMAP and TI DaVinci platforms, though this appears to be
  a coincidence.

  There are also cleanups for the Marvell Orion family and the Arm
  integrator series and a Kconfig change for Broadcom"
