ACLK400_DISP1 bus feeds some internal buses of the display subsystem, some of which are also related to TV/Mixer hardware modules. When that bus is set to 120MHz, Exynos Mixer is not able to properly handle two XRGB display planes at FullHD-60MHz. DMA underrun happens, which in turn might result in reading data out of the configured buffer, what causes IOMMU page fault and kernel panic. This change fixes the following IOMMU fault, observed, when 2 Mixer planes were enabled: exynos-sysmmu 14650000.sysmmu: 14450000.mixer: PAGE FAULT occurred at 0x20fe9000 ------------[ cut here ]------------ kernel BUG at ../drivers/iommu/exynos-iommu.c:450!

As I also want to use my WiiU adapter on ODROID C I ask you to merge this request also for this kernel version. It is a copy of this pull request for the 3.8 kernel:
