      drm: imx: Move imx-drm driver out of staging · 6556f7f8
      Philipp Zabel authored
      The imx-drm driver was put into staging mostly for the following reasons,
      all of which have been addressed or superseded:
       - convert the irq driver to use linear irq domains
       - work out the device tree bindings, this lead to the common of_graph
         bindings being used
       - factor out common helper functions, this mostly resulted in the
         component framework and drm of_graph helpers.
      
      Before adding new fixes, and certainly before adding new features,
      move it into its proper place below drivers/gpu/drm.

      Merge branch 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next
      
        Add Exynos4415 SoC support, some fixups and cleanups.
      
         Summary:
         - Resolve kernel lockup issue incurred by probe request in probe context.
           . For this, it moves all register codes of sub drivers into init function
             and adds component binding support for vidi driver.
         - Add Exynos4415 SoC support.
         - Make each manager and display object to be embedded
           in each driver context.
         - Fix and clean up FIMD and MIPI-DSI drivers.
         - Clean up unnecesary or wrong descriptions.
         - And trivial cleanups.

      Merge branch 'msm-next' of git://people.freedesktop.org/~robclark/linux into drm-next · 955289c7
      Dave Airlie authored
      Now that we have the bits needed for mdp5 atomic, here is the followup
      pull request I mentioned.  Main highlights are:
      
      1) mdp5 multiple crtc and public plane support (no more hard-coded mixer setup!)
      2) mdp5 atomic conversion
      3) couple atomic helper fixes for issues found during mdp5 atomic
      debug (reviewed by danvet.. but he didn't plane to send an
      atomic-fixes pull request so I agreed to tack them on to mine)
      
      * 'msm-next' of git://people.freedesktop.org/~robclark/linux:
        drm/atomic: shutdown *current* encoder

      Gustavo Padovan authored
      exynos_dpi_remove() should receive a exynos_drm_display but when
      DRM_EXYNOS_DPI was disabled it was receiving a struct device resulting in
      ia compiler warning.

      drm/exynos: vidi: add component support · 1d50aa9c
      Inki Dae authored
      This patch adds component support for vidi driver.
      
      vidi driver is a kms driver so it doesn't need to be registered
      to exynos_drm_subdrv_list. For this, it changes for the component
      framework to be used for vidi driver.
      
      This patch fixes below error also,

      This issue occurs when modeset to vidi is tried in case that drm_vblank_init
      is called prior to crtc creation of vidi driver. In this case, crtc number
      of vidi is invalid so any requests with the crtc number will fail.
      This patch guarantees drm_vblank_init to be called after all kms drivers
      are ready by using component framework.

      drm/exynos: fix exynos_drm_component_del · 33e2192f
      Inki Dae authored
      This patch resolves the issue that component object isn't removed
      correctly.
      
      A given component object couldn't be placed to head of drm_component_list
      so all component objects added to the drm_component_list should be checked
      to remove the given component object.
