Commit 69700db4 authored by Linus Torvalds's avatar Linus Torvalds

Merge tag 'soc-6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM SoC code updates from Arnd Bergmann:
 "This time there are only fairly minor cleanups across the i.MX,
  ixp4xx, ux500 and renesas platforms.

  The only notable update is a change to the keystone2 platform to
  switch switch it over to standard PSCI SMP bringup, which apparently
  was present in the shipped firmware almost from the start"

* tag 'soc-6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc:
