4.2-stable review patch. If anyone has any objections, please let me know.
------------------ From: Joonyoung Shim <[email protected]> commit c7d2ecd9f64c351cb4d551f1f472d0fc09c3cae8 upstream. 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.
