  ARM: EXYNOS: Remove the L2 cache latency setting for EXYNOS5
  ARM: EXYNOS: Remove leftovers of the Samsung specific power domain control
  ARM: SAMSUNG: Remove unused variable 'running' on PWM
  ARM: SAMSUNG: remove unused SPI clock headers
  ARM: S3C24XX: remove unused header <mach/bast-pmu.h>
  ARM: S3C24XX: Remove duplicate header file inclusion
  ARM: SAMSUNG: Remove description corresponding to a deleted element
