ARM: arm-soc: device tree conversions and enablement

Browse source 
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.

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.
