   1 NVIDIA Tegra Memory Controller device tree bindings
   2 ===================================================
   3
   4 Required properties:
   5 - compatible: Should be "nvidia,tegra<chip>-mc"
   6 - reg: Physical base address and length of the controller's registers.
   7 - clocks: Must contain an entry for each entry in clock-names.
   8   See ../clocks/clock-bindings.txt for details.
   9 - clock-names: Must include the following entries:
  10   - mc: the module's clock input
  11 - interrupts: The interrupt outputs from the controller.
  12 - #iommu-cells: Should be 1. The single cell of the IOMMU specifier defines
  13   the SWGROUP of the master.
  14
  15 This device implements an IOMMU that complies with the generic IOMMU binding.
  16 See ../iommu/iommu.txt for details.
