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

Pull "ARM: SoC specific updates" from Arnd Bergmann:
 "These changes are all specific to an soc family or the code for one
  soc.  Lots of work for Tegra3 this time, but also a lot of other
  platforms.  There will be another (smaller) set of soc patches later
  in the merge window for stuff that has dependencies on external trees
  or that was sent just before the merge window opened.

  The asoc tree added a few devices to the i.mx platform, which conflict
  with other devices added in the same place here.

  The tegra Makefile conflicts between a number of branches, mostly
  because of changes regarding localtimer.c, which was removed in the
  end.

  Signed-off-by: Arnd Bergmann <arnd@arndb.de>"

Fix up some trivial conflicts, including the mentioned Tegra Makefile.
