Merge tag 'samsung-soc-4.9' of git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux into next/soc

Merge "Samsung mach/soc update for v4.9" from Krzysztof Kozlowski:

1. Fix for DMA on S3C24xx. This was probably broken for long time, nobody runs
   this code... till now.
2. After fixes from Matthew Leach and Ben Dooks, most of our mach code
   and drivers is now endian-safe. Mark the platform as supporting big endian.
3. Cleanups.

* tag 'samsung-soc-4.9' of git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux:
  ARM: EXYNOS: Remove unused DMC and CMU offsets and their mappings
  ARM: s3c64xx: Delete unnecessary assignment for the field "owner"
  ARM: EXYNOS: Enable ARCH_SUPPORTS_BIG_ENDIAN explicitly
  ARM: S3C24XX: Add missing DMA device for Mini2440 board
  ARM: S3C24XX: Add dma_mask assignments for DMA devices
