Merge tag 'cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC cleanups on various subarchitectures from Olof Johansson: "Cleanup patches for various ARM platforms and some of their associated drivers. There's also a branch in here that enables Freescale i.MX to be part of the multiplatform support -- the first "big" SoC that is moved over (more multiplatform work comes in a separate branch later during the merge window)." Conflicts fixed as per Olof, including a silent semantic one in arch/arm/mach-omap2/board-generic.c (omap_prcm_restart() was renamed to omap3xxx_restart(), and a new user of the old name was added). * tag 'cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (189 commits) ARM: omap: fix typo on timer cleanup ARM: EXYNOS: Remove unused regs-mem.h file ARM: EXYNOS: Remove unused non-dt support for dwmci controller ARM: Kirkwood: Use hw_pci.ops instead of hw_pci.scan ARM: OMAP3: cm-t3517: use GPTIMER for system clock ARM: OMAP2+: timer: remove CONFIG_OMAP_32K_TIMER ARM: SAMSUNG: use devm_ functions for ADC driver ARM: EXYNOS: no duplicate mask/unmask in eint0_15 ARM: S3C24XX: SPI clock channel setup is fixed for S3C2443 ARM: EXYNOS: Remove i2c0 resource information and setting of device names ARM: Kirkwood: checkpatch cleanups ARM: Kirkwood: Fix sparse warnings. ARM: Kirkwood: Remove unused includes ARM: kirkwood: cleanup lsxl board includes ARM: integrator: use BUG_ON where possible ARM: integrator: push down SC dependencies ARM: integrator: delete static UART1 mapping ARM: integrator: delete SC mapping on the CP ARM: integrator: remove static CP syscon mapping ARM: integrator: remove static AP syscon mapping ...
