Merge branch 'samsung/exynos-multiplatform' into next/multiplatform 



These patches get us closer to adding multiplatform support on
the Exynos platform, they are part of a longer series of
patches.  This would get all the simple stuff out of the
way, and I don't think there is a big risk of introducing
regressions with these.

A lot of the other patches have already been merged into
subsystem trees. After this series in in arm-soc, what is
left comes down to

* The ASoC conversion to dmaengine won't make it unless someone
  who knows that code better steps up to do it right away. This
  means that we won't have audio in a 3.10 multiplatform kernel
  on Exynos, but it will still work for users that don't enable
  multiplatform.

* The irqchip (combiner), clk and clksource patches are all based
  on top   of other changesets we pulled in from your trees, so I
  would not make them part of the next/multiplatform branch. We can
  apply them on top of the next/drivers branch once they are
  tested successfully.

* A trivial patch is needed in the end to actually make
  CONFIG_ARCH_EXYNOS visible in multiplatform configurations.
  We will do that as a separate patch once everything else is
  there.
