NVIDIA Tegra Memory Controller device tree bindings
===================================================

Required properties:
- compatible: Should be "nvidia,tegra<chip>-mc"
- reg: Physical base address and length of the controller's registers.
- 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: The interrupt outputs from the controller.
- #iommu-cells: Should be 1. The single cell of the IOMMU specifier defines
  the SWGROUP of the master.

This device implements an IOMMU that complies with the generic IOMMU binding.
See ../iommu/iommu.txt for details.

Example:
--------

	mc: memory-controller@0,70019000 {
		compatible = "nvidia,tegra124-mc";
		reg = <0x0 0x70019000 0x0 0x1000>;
		clocks = <&tegra_car TEGRA124_CLK_MC>;
		clock-names = "mc";

		interrupts = <GIC_SPI 77 IRQ_TYPE_LEVEL_HIGH>;

		#iommu-cells = <1>;
	};

	sdhci@0,700b0000 {
		compatible = "nvidia,tegra124-sdhci";
		...
		iommus = <&mc TEGRA_SWGROUP_SDMMC1A>;
	};
