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 */

	};
