Merge tag 'cleanup-for-3.16' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc into next
Pull ARM SoC cleanups from Olof Johansson: "Cleanups for 3.16. Among these are: - a bunch of misc cleanups for Broadcom platforms, mostly housekeeping - enabling Common Clock Framework on the older s3c24xx Samsung chipsets - cleanup of the Versatile Express system controller code, moving it to syscon - power management cleanups for OMAP platforms plus a handful of other cleanups across the place" * tag 'cleanup-for-3.16' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (87 commits) ARM: kconfig: allow PCI support to be selected with ARCH_MULTIPLATFORM clk: samsung: fix build error ARM: vexpress: refine dependencies for new code clk: samsung: clk-s3c2410-dlck: do not use PNAME macro as it declares __initdata cpufreq: exynos: Fix the compile error ARM: S3C24XX: move debug-macro.S into the common space ARM: S3C24XX: use generic DEBUG_UART_PHY/_VIRT in debug macro ARM: S3C24XX: trim down debug uart handling ARM: compressed/head.S: remove s3c24xx special case ARM: EXYNOS: Remove unnecessary inclusion of cpu.h ARM: EXYNOS: Migrate Exynos specific macros from plat to mach ARM: EXYNOS: Remove exynos_subsys registration ARM: EXYNOS: Remove duplicate lines in Makefile ARM: EXYNOS: use v7_exit_coherency_flush macro for cache disabling ARM: OMAP4: PRCM: remove references to cm-regbits-44xx.h from PRCM core files ARM: OMAP3/4: PRM: add support of late_init call to prm_ll_ops ARM: OMAP3/OMAP4: PRM: add prm_features flags and add IO wakeup under it ARM: OMAP3/4: PRM: provide io chain reconfig function through irq setup ARM: OMAP2+: PRM: remove unnecessary cpu_is_XXX calls from prm_init / exit ARM: OMAP2+: PRCM: cleanup some header includes ...
