      drm/rockchip: use drm_gem_mmap helpers · 41315b79
      Daniel Kurtz authored
      Rather than (incompletely [0]) re-implementing drm_gem_mmap() and
      drm_gem_mmap_obj() helpers, call them directly from the rockchip mmap
      routines.
      
      Once the core functions return successfully, the rockchip mmap routines
      can still use dma_mmap_attrs() to simply mmap the entire buffer.
      
      [0] Previously, we were performing the mmap() without first taking a
      reference on the underlying gem buffer.  This could leak ptes if the gem
      object is destroyed while userspace is still holding the mapping.

      drm: Always enable atomic API · 8b72ce15
      Daniel Stone authored
      Now that the interface has been proven by a port of Weston (using all
      atomic features including TEST_ONLY), remove the module parameter
      guarding the atomic API from being exposed, and let it run free in the
      wild.

      Since there's only one global instance ever we don't need to have

      This patch fixes the below build error reported by Stephen,
      
           Stephen reported:
           After merging the drm-exynos tree, today's linux-next build (x86_64

      drm/dp/mst: take lock around looking up the branch device on hpd irq · 9eb1e57f
      Dave Airlie authored
      If we are doing an MST transaction and we've gotten HPD and we
      lookup the device from the incoming msg, we should take the mgr
      lock around it, so that mst_primary and mstb->ports are valid.

      This validates the mst_primary under the lock, and then calls
      into the check and send function. This makes the code a lot
      easier to understand the locking rules in.

      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.
