-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 */
-	};
