Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus

Pull MIPS updates from Ralf Baechle:
 "The whole series has been sitting in -next for quite a while with no
  complaints.  The last change to the series was before the weekend the
  removal of an SPI patch which Grant - even though previously acked by
  himself - appeared to raise objections.  So I removed it until the
  situation is clarified.  Other than that all the patches have the acks
  from their respective maintainers, all MIPS and x86 defconfigs are
  building fine and I'm not aware of any problems introduced by this
  series.

  Among the key features for this patch series is a sizable patchset for
  Lantiq which among other things introduces support for Lantiq's
  flagship product, the FALCON SOC.  It also means that the opensource
  developers behind this patchset have overtaken Lantiq's competing
  inhouse development team that was working behind closed doors.

  Less noteworthy the ath79 patchset which adds support for a few more
  chip variants, cleanups and fixes.  Finally the usual dose of tweaking
  of generic code."

Fix up trivial conflicts in arch/mips/lantiq/xway/gpio_{ebu,stp}.c where
printk spelling fixes clashed with file move and eventual removal of the
printk.
