Merge tag 'arm-soc-5.13' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM SoC updates from Arnd Bergmann:
 "Almost all SoC code changes this time are for the TI OMAP platform,
  which continues its decade-long quest to move from describing a
  complex SoC in code to device tree.

  Aside from this, the Uniphier platform has a new maintainer and some
  platforms have minor bugfixes and cleanups that were not urgent enough
  for v5.12"
