Merge branch 'for-3.5/dt2' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra into for-next

Stephen Warren <swarren@wwwdotorg.org> writes:
  This branch is based on the merge of the following branches from the
  Tegra repo, which are all already pulled into arm-soc:

  for-3.5/tegra30-audio
  for-3.5/usb-ulpi
  for-3.5/dt
  ... which are all based on for-3.5/gpio-pinmux

* 'for-3.5/dt2' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra:
  ARM: dt: tegra: invert status=disable vs status=okay
  ARM: dt: tegra: consistent basic property ordering
  ARM: dt: tegra: sort nodes based on bus order
  ARM: dt: tegra: remove duplicate device_type property
  ARM: dt: tegra: consistenly use lower-case for hex constants
  ARM: dt: tegra: format regs properties consistently
  ARM: dt: tegra: gpio comment cleanup
  ARM: dt: tegra: remove unnecessary unit addresses
  ARM: dt: tegra: whitespace cleanup
  ARM: dt: tegra cardhu: fix typo in SDHCI node name
  ARM: dt: tegra: cardhu: register core regulator tps62361
  ARM: dt: tegra30.dtsi: Add SMMU node
  ARM: dt: tegra20.dtsi: Add GART node
  ARM: dt: tegra30.dtsi: Add Memory Controller(MC) nodes
  ARM: dt: tegra20.dtsi: Add Memory Controller(MC) nodes
  ARM: dt: tegra: Add device tree support for AHB
