Merge tag 'samsung-drivers-exynos-mfc-4.8' of git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux into next/drivers

Browse Source 
Topic branch for Exynos MFC changes for v4.8:
Pull s5p-mfc changes from media tree so the arm/mach-exynos code
could be removed. The bindings are converted to generic reserved memory
bindings.

* tag 'samsung-drivers-exynos-mfc-4.8' of git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux:
  ARM: dts: exynos: Enable MFC device on Exynos4412 Odroid boards
  ARM: dts: exynos: Convert MFC device to generic reserved memory bindings
  ARM: EXYNOS: Remove code for MFC custom reserved memory handling
  media: s5p-mfc: add iommu support
  media: s5p-mfc: replace custom reserved memory handling code with generic one
  media: s5p-mfc: use generic reserved memory bindings
  of: reserved_mem: add support for using more than one region for given device
  media: set proper max seg size for devices on Exynos SoCs
  media: vb2-dma-contig: add helper for setting dma max seg size
  s5p-mfc: Fix race between s5p_mfc_probe() and s5p_mfc_open()
  s5p-mfc: Add release callback for memory region devs
  s5p-mfc: Set device name for reserved memory region devs
