Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM SoC platform updates from Olof Johansson:
 "Most of these are for MMP (seeing a bunch of cleanups and refactorings
  for the first time in a while), and for OMAP (a bunch of cleanups and
  added support for voltage controller on OMAP4430)"

* tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (51 commits)
  ARM: OMAP2+: Add missing put_device() call in omapdss_init_of()
  OMAP2: fixup doc comments in omap_device
  ARM: OMAP1: drop duplicated dependency on ARCH_OMAP1
  ARM: ASPEED: update default ARCH_NR_GPIO for ARCH_ASPEED
  ARM: imx: use generic function to exit coherency
  ARM: tegra: Use WFE for power-gating on Tegra30
  ARM: tegra: Fix FLOW_CTLR_HALT register clobbering by tegra_resume()
  ARM: exynos: Enable exynos-asv driver for ARCH_EXYNOS
  ARM: s3c: Rename s5p_usb_phy functions
