Merge tag 'cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC cleanups from Olof Johansson: "This branch contains code cleanups, moves and removals for 3.12. There's a large number of various cleanups, and a nice net removal of 13500 lines of code. Highlights worth mentioning are: - A series of patches from Stephen Boyd removing the ARM local timer API. - Move of Qualcomm MSM IOMMU code to drivers/iommu. - Samsung PWM driver cleanups from Tomasz Figa, removing legacy PWM driver and switching over to the drivers/pwm one. - Removal of some unusued auto-generated headers for OMAP2+ (PRM/CM). There's also a move of a header file out of include/linux/i2c/ to platform_data, where it really belongs. It touches mostly ARM platform code for include changes so we took it through our tree" * tag 'cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (83 commits) ARM: OMAP2+: Add back the define for AM33XX_RST_GLOBAL_WARM_SW_MASK gpio: (gpio-pca953x) move header to linux/platform_data/ arm: zynq: hotplug: Remove unreachable code ARM: SAMSUNG: Remove unnecessary exynos4_default_sdhci*() tegra: simplify use of devm_ioremap_resource ARM: SAMSUNG: Remove plat/regs-timer.h header ARM: SAMSUNG: Remove remaining uses of plat/regs-timer.h header ARM: SAMSUNG: Remove pwm-clock infrastructure ARM: SAMSUNG: Remove old PWM timer platform devices pwm: Remove superseded pwm-samsung-legacy driver ARM: SAMSUNG: Modify board files to use new PWM platform device ARM: SAMSUNG: Rework private data handling in dev-backlight pwm: Add new pwm-samsung driver ARM: mach-mvebu: remove redundant DT parsing and validation ARM: msm: Only compile io.c on platforms that use it iommu/msm: Move mach includes to iommu directory ARM: msm: Remove devices-iommu.c ARM: msm: Move mach/board.h contents to common.h ARM: msm: Migrate msm_timer to CLOCKSOURCE_OF_DECLARE ARM: msm: Remove TMR and TMR0 static mappings ...
