The sysmmu_fimd1_1 should bind the clock CLK_SMMU_FIMD1M1, not the clock CLK_SMMU_FIMD1M0. CLK_SMMU_FIMD1M0 is a clock for the sysmmu_fimd1_0. This wrong clock binding causes the problem that is blocked in iommu_map function when IOMMU is enabled and exynos-drm driver tries to allocate buffer via DMA mapping API on Odroid-XU3 board.
