| 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>; |
| }; |
