      drm/tegra: Implement VBLANK support · 6e5ff998
      由 Thierry Reding 提交于 
      Implement support for the VBLANK IOCTL. Note that Tegra is somewhat
special in this case because it doesn't use the generic IRQ support
provided by the DRM core (DRIVER_HAVE_IRQ) but rather registers one
interrupt handler for each display controller.

While at it, clean up the way that interrupts are enabled to ensure
that the VBLANK interrupt only gets enabled when required.

      drm/tegra: Implement .mode_set_base() · 23fb4740
      由 Thierry Reding 提交于 
      The sequence for replacing the scanout buffer is much shorter than a
full mode change operation so implementing this callback considerably
speeds up cases where only a new framebuffer is to be scanned out.

      drm/tegra: Add plane support · f34bc787
      由 Thierry Reding 提交于 
      Add support for the B and C planes which support RGB and YUV pixel
formats and can be used as overlays or hardware cursor. Currently 32-bit
XRGB as well as UYVY, YUV420 and YUV422 pixel formats are advertised.
Other formats should be easy to add but these are the most common ones
and should cover the majority of use-cases.

      drm/tegra: Remove bogus tegra_framebuffer structure · 894752bb
      由 Thierry Reding 提交于 
      Tegra uses the CMA FB helpers so framebuffers passed to the driver need
to use the corresponding functions to access the underlying GEM objects.

This used to work because struct tegra_framebuffer was sufficiently
similar to struct drm_fb_cma but that isn't guaranteed to stay that way.

      drm: Add consistency check for page-flipping · 8cf1e981
      由 Thierry Reding 提交于 
      Driver implementations of the drm_crtc's .page_flip() function are
required to update the crtc->fb field on success to reflect that the new
framebuffer is now in use. This is important to keep reference counting
on the framebuffers balanced.

While at it, document this requirement to keep others from falling into
the same trap.

      Merge branch 'exynos-drm-next' of... · c976cb37
      由 Dave Airlie 提交于 
      Merge branch 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next

The summary:
. Add display mode check operaion to mixer driver
  - Mixer IP also can put certain restrictions on the proposed
    display modes and these restrictions need to be considered
    during mode negotiation, which happens immediately after
    edid parsing.
. Set correct mode for range of resolutions
  - With this patch, the mixer driver could find the correct mode
    for the range of resolutions upto 1080 vertical lines.
. Support extra resolution for hdmi
  - This patch programs the core and timing generator registers
    using the timing data provided in drm_display_mode without
    hard-coded configurations. So this patch adds additional PHY
    configs to allow us to support more permissible resolutions
    and refresh rates.
. Add device tree support for g2d
  - This patch adds just the compatible string for exynos5250 SoC
    so that with device tree enabling, this driver can be probed.
. And bug fixes and code cleanups.

* 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos:
  drm/exynos: Add device tree based discovery support for G2D
  drm/exynos: hdmi: support extra resolutions using drm_display_mode timings
  drm/exynos: mixer: set correct mode for range of resolutions
  drm/exynos: implement display-mode-check callback in mixer driver
  drm/exynos: add display-mode-check operation to exynos_mixer_ops struct
  drm/exynos: release resources properly when fb creation is failed.
  drm/exynos: fix wrong pointer access at vm close.
  drm/exynos: Add missing braces around sizeof
  drm/exynos: consider exception case to fb handle creation
  drm/exynos: fix iommu address allocation order

      gma500: Fix n, m1 and m2 clock limits for sdvo and lvds · 907a773b
      由 Patrik Jakobsson 提交于 
      The values of n, m1 and m2 needs to be subtracted by 2 before writing them to
the FP register. The dot clock calculation already thinks of these values in
register form so we must also specify them as such.
