+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 */
+ };
