      drm/exynos: fix display on issue · 44c91697
      Inki Dae 提交于
      When crtc_funcs->dpms callback is called, exynos_crtc->dpms
      and exynos_encoder->dpms are changed to new mode. But if user
      requests dpms mode operation, OFF -> ON, when crtc's dpms callback
      is called, exynos_encoder->dpms is also changed to ON. This
      makes encoder's dpms callback call be ignored so display power
      couldn't become on again.
      
      This patch removes exynos_encoder->dpms changing and adds 'updated'
      variable to exynos_drm_encoder structure to avoid duplicated overlay
      updating.

      drm/exynos: Fix fb_videomode <-> drm_mode_modeinfo conversion · f7d86075
      Laurent Pinchart 提交于
      The fb_videomode structure stores the front porch and back porch in the
      right_margin and left_margin fields respectively. right_margin should
      thus be computed with hsync_start - hdisplay, and left_margin with
      htotal - hsync_end. The same holds for the vertical direction.

      DRM: add DRM Driver for Samsung SoC EXYNOS4210. · 1c248b7d
      Inki Dae 提交于
      This patch is a DRM Driver for Samsung SoC Exynos4210 and now enables
      only FIMD yet but we will add HDMI support also in the future.
      
      this patch is based on git repository below:
      git://people.freedesktop.org/~airlied/linux.git
      branch name: drm-next
      commit-id: 88ef4e3f
      
      you can refer to our working repository below:
      http://git.infradead.org/users/kmpark/linux-2.6-samsung
      branch name: samsung-drm
      
      We tried to re-use lowlevel codes of the FIMD driver(s3c-fb.c
      based on Linux framebuffer) but couldn't so because lowlevel codes
      of s3c-fb.c are included internally and so FIMD module of this driver has
      its own lowlevel codes.
      
      We used GEM framework for buffer management and DMA APIs(dma_alloc_*)
      for buffer allocation so we can allocate physically continuous memory
      for DMA through it and also we could use CMA later if CMA is applied to
      mainline.
      
      Refer to this link for CMA(Continuous Memory Allocator):
      http://lkml.org/lkml/2011/7/20/45
      
      this driver supports only physically continuous memory(non-iommu).

      v5: < http://comments.gmane.org/gmane.comp.video.dri.devel/60802 >
      
      Changelog v2:
      DRM: add DRM_IOCTL_SAMSUNG_GEM_MMAP ioctl command.
      
          this feature maps user address space to physical memory region
          once user application requests DRM_IOCTL_SAMSUNG_GEM_MMAP ioctl.
      
      DRM: code clean and add exception codes.
      
      Changelog v3:
      DRM: Support multiple irq.
      
          FIMD and HDMI have their own irq handler but DRM Framework can regiter
          only one irq handler this patch supports mutiple irq for Samsung SoC.
      
      DRM: Consider modularization.
      
          each DRM, FIMD could be built as a module.
      
      DRM: Have indenpendent crtc object.
      
          crtc isn't specific to SoC Platform so this patch gets a crtc
          to be used as common object.
          created crtc could be attached to any encoder object.
      
      DRM: code clean and add exception codes.
      
      Changelog v4:
      DRM: remove is_defult from samsung_fb.
      
          is_default isn't used for default framebuffer.
      
      DRM: code refactoring to fimd module.
          this patch is be considered with multiple display objects and
          would use its own request_irq() to register a irq handler instead of
          drm framework's one.
      
      DRM: remove find_samsung_drm_gem_object()
      
      DRM: move kernel private data structures and definitions to driver folder.
      
          samsung_drm.h would contain only public information for userspace
          ioctl interface.
      
      DRM: code refactoring to gem modules.
          buffer module isn't dependent of gem module anymore.
      
      DRM: fixed security issue.
      
      DRM: remove encoder porinter from specific connector.
      
          samsung connector doesn't need to have generic encoder.
      
      DRM: code clean and add exception codes.
      
      Changelog v5:
      DRM: updated fimd(display controller) driver.
          added various pixel formats, color key and pixel blending features.
      
      DRM: removed end_buf_off from samsung_drm_overlay structure.
          this variable isn't used and end buffer address would be
          calculated by each sub driver.
      
      DRM: use generic function for mmap_offset.
          replaced samsung_drm_gem_create_mmap_offset() and
          samsung_drm_free_mmap_offset() with generic ones applied
          to mainline recentrly.
      
      DRM: removed unnecessary codes and added exception codes.
      
      DRM: added comments and code clean.
      
      Changelog v6:
      DRM: added default config options.
      
      DRM: added padding for 64-bit align.
      
      DRM: changed prefix 'samsung' to 'exynos'
