Merge tag 'cleanup2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Cleanups for the Samsung platforms Various cleanup changes that the device driver changes are built upon. Since the samsung cleanups depend on the device tree series, which depends on the first set of cleanups for tegra. * tag 'cleanup2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: ARM: EXYNOS: Use gpio_request_one ARM: S5PV210: Use gpio_request_one ARM: S3C64XX: Modified according to SPI consolidation work ARM: S5PV210: Modified files for SPI consolidation work ARM: S5P64X0: Modified files for SPI consolidation work ARM: S5PC100: Modified files for SPI consolidation work ARM: S3C64XX: Modified files for SPI consolidation work ARM: SAMSUNG: Consolidation of SPI platform devices to plat-samsung ARM: SAMSUNG: Remove SPI bus clocks from platform data ARM: S5PV210: Add SPI clkdev support ARM: S5P64X0: Add SPI clkdev support ARM: S5PC100: Add SPI clkdev support ARM: S3C64XX: Add SPI clkdev support spi/s3c64xx: Use bus clocks created using clkdev mmc: sdhci-s3c: Use generic clock names for sdhci bus clock options ARM: SAMSUNG: Add lookup of sdhci-s3c clocks using generic names ARM: SAMSUNG: Remove SDHCI bus clocks from platform data ARM: SAMSUNG: Use kmemdup rather than duplicating its implementation ARM: EXYNOS: remove exynos4_scu_enable()
