Merge tag 'multiplatform-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC multiplatform updates from Olof Johansson: "More multiplatform enablement for ARM platforms. The ones converted in this branch are: - bcm2835 - cns3xxx - sirf - nomadik - msx - spear - tegra - ux500 We're getting close to having most of them converted! One of the larger platforms remaining is Samsung Exynos, and there are a bunch of supporting patches in this merge window for it. There was a patch in this branch to a early version of multiplatform conversion, but it ended up being reverted due to need of more bake time. The revert commit is part of the branch since it would have required rebasing multiple dependent branches and they were stable by then" * tag 'multiplatform-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (70 commits) mmc: sdhci-s3c: Fix operation on non-single image Samsung platforms clocksource: nomadik-mtu: fix up clocksource/timer Revert "ARM: exynos: enable multiplatform support" ARM: SPEAr13xx: Fix typo "ARCH_HAVE_CPUFREQ" ARM: exynos: enable multiplatform support rtc: s3c: make header file local mtd: onenand/samsung: make regs-onenand.h file local thermal/exynos: remove unnecessary header inclusions mmc: sdhci-s3c: remove platform dependencies ARM: samsung: move mfc device definition to s5p-dev-mfc.c ARM: exynos: move debug-macro.S to include/debug/ ARM: exynos: prepare for sparse IRQ ARM: exynos: introduce EXYNOS_ATAGS symbol ARM: tegra: build assembly files with -march=armv7-a ARM: Push selects for TWD/SCU into machine entries ARM: ux500: build hotplug.o for ARMv7-a ARM: ux500: move to multiplatform ARM: ux500: make remaining headers local ARM: ux500: make irqs.h local to platform ARM: ux500: get rid of <mach/[hardware|db8500-regs].h> ...
