to user space. If the syncpoint does not have an associated base, the
function returns -ENXIO.

db7fbdfd25 drm/tegra: Support bottom-up buffer objects
The gr3d engine renders images bottom-up. Allow buffers that are used
for 3D content to be marked as such and implement support in the display
controller to present them properly.

773af77fc4 drm/tegra: Add support for tiled buffer objects
The gr2d and gr3d engines work more efficiently on buffers with a tiled
memory layout. Allow created buffers to be marked as tiled so that the
display controller can scan them out properly.
