Merge tag 'cleanup-for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC cleanups from Olof Johansson: "This merge window brings a good size of cleanups on various platforms. Among the bigger ones: - Removal of Samsung s5pc100 and s5p64xx platforms. Both of these have lacked active support for quite a while, and after asking around nobody showed interest in keeping them around. If needed, they could be resurrected in the future but it's more likely that we would prefer reintroduction of them as DT and multiplatform-enabled platforms instead. - OMAP4 controller code register define diet. They defined a lot of registers that were never actually used, etc. - Move of some of the Tegra platform code (PMC, APBIO, fuse, powergate) to drivers/soc so it can be shared with 64-bit code. This also converts them over to traditional driver models where possible. - Removal of legacy gpio-samsung driver, since the last users have been removed (moved to pinctrl) Plus a bunch of smaller changes for various platforms that sort of dissapear in the diffstat for the above. clps711x cleanups, shmobile header file refactoring/moves for multiplatform friendliness, some misc cleanups, etc" * tag 'cleanup-for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (117 commits) drivers: CCI: Correct use of ! and & video: clcd-versatile: Depend on ARM video: fix up versatile CLCD helper move MAINTAINERS: Add sdhci-st file to ARCH/STI architecture ARM: EXYNOS: Fix build breakge with PM_SLEEP=n MAINTAINERS: Remove Kirkwood ARM: tegra: Convert PMC to a driver soc/tegra: fuse: Set up in early initcall ARM: tegra: Always lock the CPU reset vector ARM: tegra: Setup CPU hotplug in a pure initcall soc/tegra: Implement runtime check for Tegra SoCs soc/tegra: fuse: fix dummy functions soc/tegra: fuse: move APB DMA into Tegra20 fuse driver soc/tegra: Add efuse and apbmisc bindings soc/tegra: Add efuse driver for Tegra ARM: tegra: move fuse exports to soc/tegra/fuse.h ARM: tegra: export apb dma readl/writel ARM: tegra: Use a function to get the chip ID ARM: tegra: Sort includes alphabetically ARM: tegra: Move includes to include/soc/tegra ...
