Merge branch 'next/cleanup' of git://git.linaro.org/people/arnd/arm-soc
* 'next/cleanup' of git://git.linaro.org/people/arnd/arm-soc: (125 commits) ARM: mach-mxs: fix machines' initializers order mmc: mxcmmc: explicitly includes mach/hardware.h arm/imx: explicitly includes mach/hardware.h in pm-imx27.c arm/imx: remove mx27_setup_weimcs() from mx27.h arm/imx: explicitly includes mach/hardware.h in mach-kzm_arm11_01.c arm/imx: remove mx31_setup_weimcs() from mx31.h ARM: tegra: devices.c should include devices.h ARM: tegra: cpu-tegra: unexport two functions ARM: tegra: cpu-tegra: sparse type fix ARM: tegra: dma: staticify some tables and functions ARM: tegra: tegra2_clocks: don't export some tables ARM: tegra: tegra_powergate_is_powered should be static ARM: tegra: tegra_rtc_read_ms should be static ARM: tegra: tegra_init_cache should be static ARM: tegra: pcie: 0 -> NULL changes ARM: tegra: pcie: include board.h ARM: tegra: pcie: don't cast __iomem pointers ARM: tegra: tegra2_clocks: 0 -> NULL changes ARM: tegra: tegra2_clocks: don't cast __iomem pointers ARM: tegra: timer: don't cast __iomem pointers ... Fix up trivial conflicts in arch/arm/mach-omap2/Makefile, arch/arm/mach-u300/{Makefile.boot,core.c} arch/arm/plat-{mxc,omap}/devices.c
