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.
