Merge tag 'dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC device tree conversions and enablement from Olof Johansson:
"Continued device tree conversion and enablement across a number of
platforms; Kirkwood, tegra, i.MX, Exynos, zynq and a couple of other
smaller series as well.
ux500 has seen continued conversion for platforms. Several platforms
have seen pinctrl-via-devicetree conversions for simpler
multiplatform. Tegra is adding data for new devices/drivers, and
Exynos has a bunch of new bindings and devices added as well.
So, pretty much the same progression in the right direction as the
last few releases."
Fix up conflicts as per Olof.
