When the fimd is disabled by fimd_disable(), enabled overlay layers also are disabled. If clocks for fimd are enabled by fimd_enable() on this case, it can lead IOMMU page fault. The reason is that VIDCON0_ENVID and VIDCON0_ENVID_F bits of VIDCON0 register are set still even though fimd is disabled, so it may continue display output of prior when clocks for fimd are enabled again.

With atomic modesetting all the control for CRTC, Planes, Encoders and Connectors should come from DRM core, so the driver is not allowed to enable or disable planes from inside the crtc_enable()/disable() call. But it needs to disable planes with crtc_disable in exynos driver internally. Because crtc is disabled before plane is disabled, it means plane_disable just returns without any register changes, then we cannot be sure setting register to disable plane when crtc is disable. This patch removes this chainned calls to enable plane from exynos hw drivers code letting only DRM core touch planes except to disable plane. Also it leads eliminable enabled and resume of struct exynos_drm_plane.

The reason waiting vblank is to be power gated and disabled clocks after dma operation is completed.

exynos_dsi_host_transfer() can be called through a panel driver while DSI is turning down. It is possible because the function checks only whether DSI is initialized or not, and there is a moment which DSI is set by uninitialized, but DSI is still turning down. To prevent it, DSI must be set by disabled before starting to be turned down, and exynos_dsi_host_transfer() must check whether DSI is enabled or not.

In case there are multiple pipelines and deferred probe occurs, only components of the first pipeline were bound. As a result only one pipeline was available. The main cause of this issue was dynamic generation of component match table - every component driver during probe registered itself on helper list, if there was at least one pipeline present on this list component match table were created without deferred components. This patch removes this helper list, instead it creates match table from existing devices requiring exynos_drm KMS drivers. This way match table do not depend on probe/deferral order and contains all KMS components. As a side effect patch makes the code cleaner and significantly smaller.

drm/tegra: Changes for v4.2-rc1 This contains a couple of mostly fixes for issues that have crept up in recent versions of linux-next. One issue is that DP AUX transactions of more than 4 bytes will access the wrong FIFO registers and hence become corrupt. Another fix is required to restore functionality of Tegra20 if using the GART. The current code expects the IOMMU aperture to be the complete 4 GiB address space, whereas the GART on Tegra20 only provides a 128 MiB aperture. One more issue with IOMMU support is that on 64-bit ARM, swiotlb is the default IOMMU implementation backing the DMA API. A side-effect of that is that when dma_map_sg() is called to flush caches (yes, this is a bit of a hack, but ARM does not provide a better API), swiotlb will immediately run out of memory because its bounce buffer is too small to make a framebuffer. Finally I've included a mostly cosmetic fix that stores register values in u32 rather than unsigned long to avoid sign-extension issues on 64- bit ARM. This is only a precaution since it hasn't caused any issues (yet). * tag 'drm/tegra/for-4.2-rc1' of git://anongit.freedesktop.org/tegra/linux: drm/tegra: dpaux: Registers are 32-bit drm/tegra: gem: Flush pages after allocation drm/tegra: gem: Take into account IOMMU aperture drm/tegra: dpaux: Fix transfers larger than 4 bytes
