Merge branch 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next

Summary:
. Add atomic feature support
  - Exynos also now supports atomic feature. However, it doesn't
    guarantee atomic operation yet, and is required for more cleanups.
    This time we just modified for Exynos drm driver to use atomic
    interfaces instead of legacy ones. Next time, we will enhance
    Exynos drm driver to support the atomic operation.
. Add iommu support
  - This is a patch series according to below Exynos iommu integration
    work with DT and dma-mapping subsystem,
    http://lwn.net/Articles/607626/
. Consolidate Exynos drm driver initialization.
  - This patch sereis resolves the issue that only the first compoments
    was bound when happened deferred probing for other pipelines and
    also makes the driver to be more cleanned up by moving the dispered
    codes for registering kms drivers to one place.
. Add new MIC, DECON drivers, and MIPI-DSI support for Exynos5433.
  - Add MIC(Mobile image compressor) driver. MIC is a new IP for Exynos5433
    and later, which is used to transfer frame data to MIPI-DSI controller
    compressing the data to reduce memory bandwidth.
  - Add DECON driver for Exynos5433 SoC. This IP is a dislay controller
    similar to Exynos7's one but this controller has much different registers
    from Exynos7's ones so this driver has been implemented separately.
    We will implement a helper modules for FIMD and two DECON controllers
    to remove duplicated codes later.
  - Add Exynos5433 SoC support to MIPI-DSI driver, and device tree
    relevant patches.
