Merge branch 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next
Inki writes: "- add dmabuf attach/detach feature . This patch would resolve performance deterioration issue when v4l2-based driver is using the buffer imported from gem. - drm/exynos: use DMA_ATTR_NO_KERNEL_MAPPING attribute . With gem allocation, kernel space mapping isn't allocated and also physical pages aren't mapped with the kernel space. The physical pages are mapped with kernel space though vmap function only for console framebuffer. - add the below two patches I missed. drm: exynos: moved exynos drm device registration to drm driver drm: exynos: moved exynos drm hdmi device registration to drm driver - add IPP subsystem framework and its-based device drivers. . This patch set includes fimc, rotator and gsc drivers to perform image scaling, rotation and color space conversion. - add runtime pm support to hdmi driver. - And fixups and cleanups." * 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos: (30 commits) drm/exynos: add gsc ipp driver drm/exynos: add rotator ipp driver drm/exynos: add fimc ipp driver drm/exynos: add iommu support for ipp drm/exynos: add ipp subsystem drm/exynos: support device tree for fimd drm/exynos: support extended screen coordinate of fimd drm/exynos: fix x, y coordinates for right bottom pixel drm/exynos: fix fb offset calculation for plane drm/exynos: hdmi: Fix potential NULL pointer dereference error drm/exynos: hdmi: Add CONFIG_OF and use of_match_ptr() macro drm/exynos: add support for hdmiphy power control for exynos5 drm/exynos: add runtime pm support for mixer drm/exynos: added runtime pm support for hdmi drm/exynos: fix allocation and cache mapping type drm/exynos: reorder framebuffer init sequence drm/exynos/iommu: fix return value check in drm_create_iommu_mapping() drm/exynos: remove unused vaddr member drm/exynos: use DMA_ATTR_NO_KERNEL_MAPPING attribute drm/exynos: add exception codes to exynos_drm_fbdev_create() ...
