+NVIDIA Tegra 20 GART
+
+Required properties:
+- compatible: "nvidia,tegra20-gart"
+- reg: Two pairs of cells specifying the physical address and size of
+  the memory controller registers and the GART aperture respectively.
+
+Example:
+
+	gart: gart@7000f000 {
+		compatible = "nvidia,tegra20-gart";
+		reg = < 0x7000f000 0x00000100    /* controller registers */
+		        0x58000000 0x02000000 >; /* GART aperture */
