Pull "ARM: global cleanups" from Arnd Bergmann: "Quite a bit of code gets removed, and some stuff moved around, mostly the old samsung s3c24xx stuff. There should be no functional changes in this series otherwise. Some cleanups have dependencies on other arm-soc branches and will be sent in the second round. Signed-off-by: Arnd Bergmann <arnd@arndb.de>" Fixed up trivial conflicts mainly due to #include's being changes on both sides. * tag 'cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (121 commits) ep93xx: Remove unnecessary includes of ep93xx-regs.h ep93xx: Move EP93XX_SYSCON defines to SoC private header ep93xx: Move crunch code to mach-ep93xx directory ep93xx: Make syscon access functions private to SoC ep93xx: Configure GPIO ports in core code ep93xx: Move peripheral defines to local SoC header ep93xx: Convert the watchdog driver into a platform device. ep93xx: Use ioremap for backlight driver ep93xx: Move GPIO defines to gpio-ep93xx.h ep93xx: Don't use system controller defines in audio drivers ep93xx: Move PHYS_BASE defines to local SoC header file ARM: EXYNOS: Add clock register addresses for EXYNOS4X12 bus devfreq driver ARM: EXYNOS: add clock registers for exynos4x12-cpufreq PM / devfreq: update the name of EXYNOS clock registers that were omitted PM / devfreq: update the name of EXYNOS clock register ARM: EXYNOS: change the prefix S5P_ to EXYNOS4_ for clock ARM: EXYNOS: use static declaration on regarding clock ARM: EXYNOS: replace clock.c for other new EXYNOS SoCs ARM: OMAP2+: Fix build error after merge ARM: S3C24XX: remove call to s3c24xx_setup_clocks ...
