[RFC v2 0/5] Add NVIDIA Tegra DRM support

[Thierry Reding]

This series adds a basic DRM driver for NVIDIA Tegra 2 processors. It
currently only supports the RGB output and I've successfully tested it
against the fbcon kernel module and the xf86-video-modesetting driver.
The code uses the Tegra's IOMMU/GART to remap non-contiguous memory.
This means that currently video memory is limited to 32 MB, the size of
the GART aperture.

Changes in v2:
- split into several smaller source files
- represent individual devices in DT
- add drivers for individual devices
- EDID probing support via "ddc" property
- EDID support in DT using binary blobs
- basic (non-working) HDMI support
- support for carveout memory in DT

A lot of the above are really just stub implementations. Most notably
HDMI support is pretty much a copy of what NVIDIA has in their
downstream kernels, though I wasn't able to make it work except for the
EDID probing (I probably missed some pieces). Carveout memory also isn't
used right now.

Still this should now be in a state where other people (like Jon and
Terje from NVIDIA) and Lucas can start contributing. This series is
based on next-20120424.
