+NVIDIA Tegra AHB
+
+Required properties:
+- compatible : For Tegra20, must contain "nvidia,tegra20-ahb". For
+ Tegra30, must contain "nvidia,tegra30-ahb". Otherwise, must contain
+ '"nvidia,<chip>-ahb", "nvidia,tegra30-ahb"' where <chip> is tegra124,
+ tegra132, or tegra210.
+- reg : Should contain 1 register ranges(address and length). For
+ Tegra20, Tegra30, and Tegra114 chips, the value must be <0x6000c004
+ 0x10c>. For Tegra124, Tegra132 and Tegra210 chips, the value should
+ be be <0x6000c000 0x150>.
+
+Example (for a Tegra20 chip):
+ ahb: ahb@6000c004 {
+ compatible = "nvidia,tegra20-ahb";
+ reg = <0x6000c004 0x10c>; /* AHB Arbitration + Gizmo Controller */
+ };
