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

Pull ARM SoC fixes from Olof Johansson:
 "I didn't get a batch in this weekend, so here's what we queued up last
  week and today.

   - A couple of defconfigs add back debugfs -- it used to be implicitly
     enabled through CONFIG_TRACING, but 0e4a459f ("tracing:
     Remove unnecessary DEBUG_FS dependency") removed that.

   - The rest are mostly minor fixlets of the usual kind; some DT
     tweaks, a headerfile refactor that needs a build fix now, etc"
