-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 */
- };
