Merge tag 'multiplatform-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC multiplatform updates from Olof Johansson:
"More multiplatform enablement for ARM platforms. The ones converted
in this branch are:
- bcm2835
- cns3xxx
- sirf
- nomadik
- msx
- spear
- tegra
- ux500
We're getting close to having most of them converted!
One of the larger platforms remaining is Samsung Exynos, and there are
a bunch of supporting patches in this merge window for it. There was
a patch in this branch to a early version of multiplatform conversion,
but it ended up being reverted due to need of more bake time. The
revert commit is part of the branch since it would have required
rebasing multiple dependent branches and they were stable by then"
