Hello, Main changes for Exynos SYSMMU (IOMMU) driver has been finally scheduled for merging - see https://git.kernel.org/cgit/linux/kernel/git/joro/iommu.git/commit/?h=next
To let Exynos IOMMU driver work correctly, some fixes are also needed in Exynos DRM driver. To ease merge process I've decided to rebased Exynos DRM changes onto latest exynos-drm-next tree from: git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos.git exynos-drm-next I've also added one more patch fixing issue, which can be observed when upcoming IOMMU probe deferal patches has been applied. To hide dma-mapping internals from Exynos DRM driver, a direct check for NULL has been replaced by more error-proof comparison of dma_get_ops() values. Inki: could you queue those patches to exynos-drm-next and get them merged to v4.2 to have it functional for the release?
