-NVIDIA Tegra20 MC(Memory Controller)
-
-Required properties:
-- compatible : "nvidia,tegra20-mc-gart"
-- reg : Should contain 2 register ranges: physical base address and length of
- the controller's registers and the GART aperture respectively.
-- clocks: Must contain an entry for each entry in clock-names.
- See ../clocks/clock-bindings.txt for details.
-- clock-names: Must include the following entries:
- - mc: the module's clock input
-- interrupts : Should contain MC General interrupt.
-- #reset-cells : Should be 1. This cell represents memory client module ID.
- The assignments may be found in header file <dt-bindings/memory/tegra20-mc.h>
- or in the TRM documentation.
-- #iommu-cells: Should be 0. This cell represents the number of cells in an
- IOMMU specifier needed to encode an address. GART supports only a single
- address space that is shared by all devices, therefore no additional
- information needed for the address encoding.

-Example:
- mc: memory-controller@7000f000 {
- compatible = "nvidia,tegra20-mc-gart";
- reg = <0x7000f000 0x400 /* controller registers */
- 0x58000000 0x02000000>; /* GART aperture */
- clocks = <&tegra_car TEGRA20_CLK_MC>;
- clock-names = "mc";
- interrupts = <GIC_SPI 77 0x04>;
- #reset-cells = <1>;
- #iommu-cells = <0>;
- };
