2015-06-22of: add helper for getting endpoint node of specific identifiersHyungwon Hwang
When there are multiple ports or multiple endpoints in a port, they have to be distinguished by the value of reg property. It is common. The drivers can get the specific endpoint in the specific port via this function. Now the drivers have to implement this code in themselves or have to force the order of dt nodes to get the right node.

2015-06-20drm/exynos: do not wait for vblank at atomic operationInki Dae
This patch resolves the issue that refresh rate got low at extension mode test with fimd and vidi combination. The problem was because atomic_commit callback waited for the completion of vblank to gaurantee crtc relevant registers are updated from shadow registers to real ones. However, the waiting there is really unnecessary because page flip operation does already it. Signed-off-by: Inki Dae <inki.dae@samsung.com>

2015-06-20drm/exynos: fimd: fix page fault issue with iommuInki Dae
This patch resolves page fault issue with iommu and atomic feature when modetest test application is terminated. ENWIN_F field of WINCONx register enables or disable a dma channel to each hardware overlay - the value of the field will be updated to real register after vsync. So this patch makes sure the dma channel is disabled by waiting for vsync one time after clearing shadow registers to all dma channels.

2015-06-20drm/exynos: initialize VIDCON0 when fimd is disabledJoonyoung Shim
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.

2015-06-20drm/exynos: remove chained calls to enableJoonyoung Shim
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.

2015-06-20drm/exynos: dsi: check whether dsi is enabled before sending dataHyungwon Hwang
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.

2015-06-20drm/exynos: fix broken component binding in case of multiple pipelinesAndrzej Hajda
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.

git://anongit.freedesktop.org/tegra/linux into drm-next 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

buf_size_in_bytes must be large enough to hold ->num_watch_points and watch_mode so I have added a sizeof(int) * 2 to the minimum size. Also we have to subtract sizeof(*args) from the max args_idx limit so that it matches the allocation. Also I changed a > to >= for the last compare.

Ensure that the duplicate and destroy plane state operations will always be in sync with the DRM core implementation of the plane state by using the __drm_atomic_helper_plane_duplicate_state() and __drm_atomic_helper_plane_destroy_state() functions designed especially for this purpose.

2015-06-16drm: rcar-du: Convert rcar_du_encoders_init_one() return value to 0/<0Laurent Pinchart
The function returns 1 on success, and either 0 or a negative error code on failure. As the 0 and negative values don't need to be differentiated by the caller, convert it to the usual scheme of returning 0 on success and a negative error code on failure.
