Video Planes, Graphics Planes and Z-ordering support on Jetson TK1

Does NVIDIA Tegra K1 platform support two graphics planes and one video plane? Also, does the TK1 platform provide support for Z-Ordering?

The TRM section 21 (especially 21.1.3) describes the features.

But unfortunately I don’t know if you can use those explicitly under X.Org.
