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. Note that this is very early work-in-progress and there is a lot of room for improvement and cleanup. You'll also note that there is still a whole lot of debugging output, most of which is disabled by default. However I explicitly wanted to post this early to get feedback and to discuss options on how to get this included in the mainline kernel. I have been in contact with some people at NVIDIA and they seem to be willing to work together on a solution that satisfies both their requirements and those of the community.
