[GIT PULL] drm/tegra: Changes for v3.19-rc1

[Thierry Reding]

Hi Dave,

The following changes since commit ba6b3be0a088b831c95431f8528d034c2dd2542f:

  Merge branch 'drm/panel/for-next' into drm/tegra/for-next (2014-11-13 16:09:48 +0100)

are available in the git repository at:

  git://people.freedesktop.org/~tagr/linux tags/drm/tegra/for-3.19-rc1

for you to fetch changes up to 7e0180e3570cc791e95e6b6cd5fbeb0aedc62776:

  drm/tegra: gem: Check before freeing CMA memory (2014-11-13 16:18:34 +0100)

Note that this will cause a couple of trivial merge conflicts with the
Tegra pull request I sent out earlier targetting v3.18-rc5. Let me know
if you want me to rebase on top of that pull request and resolve there.

Thanks,
Thierry

drm/tegra: Changes for v3.19-rc1

The highlights in this pull request are:

  * IOMMU support: The Tegra DRM driver can now deal with discontiguous
    buffers if an IOMMU exists in the system. That means it can allocate
    using drm_gem_get_pages() and will map them into IOVA space via the
    IOMMU API. Similarly, non-contiguous PRIME buffers can be imported
    from a different driver, which allows better integration with gk20a
    (nouveau) and less hacks.

  * Universal planes: This is precursory work for atomic modesetting and
    will allow hardware cursor support to be implemented on pre-Tegra114
    where RGB cursors were not supported.

  * DSI ganged-mode support: The DSI controller can now gang up with a
    second DSI controller to drive high resolution DSI panels.

Besides those bigger changes there is a slew of fixes, cleanups, plugged
memory leaks and so on.
