Merge tag 'multiplatform' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC multiplatform conversion patches from Olof Johansson:
"Here are more patches in the progression towards multiplatform, sparse
irq conversions in particular.
Tegra has a handful of cleanups and general groundwork, but is not
quite there yet on full enablement.
Platforms that are enabled through this branch are VT8500 and Zynq.
Note that i.MX was converted in one of the earlier cleanup branches as
well (before we started a separate topic for multiplatform). And both
new platforms for this merge window, sunxi and bcm, were merged with
multiplatform support enabled."
Fix up conflicts mostly as per Olof.
