[RFC 0/3] drm/tegra: Add 3D support

[Thierry Reding]

This small series of patches adds support for the 3D engine found on
NVIDIA Tegra SoCs. It builds on top of Terje's and Arto's host1x and
gr2d patches. A couple of things still need to be done before this
can be merged, though.

Patch 1 is the central piece of the series. It adds support for using
the gr3d engine via the same DRM IOCTLs that gr2d uses. A very basic
set of programs to test this can be found here[0].

Patch 2 adds support for the XBGR8888 format, which seems to be what
most gr3d programs use. It also adds the RGB565 as a format supported
by planes. This latter part could be moved to a separate patch, but I
didn't think that was necessary.

Patch 3 finally allows buffer objects to be marked as tiled so that
the display controller can scan them out appropriately.
