      1OMAP2+ IOMMU
      2
      3Required properties:
      4- compatible : Should be one of,
      5		"ti,omap2-iommu" for OMAP2/OMAP3 IOMMU instances
      6		"ti,omap4-iommu" for OMAP4/OMAP5 IOMMU instances
      7		"ti,dra7-dsp-iommu" for DRA7xx DSP IOMMU instances
      8		"ti,dra7-iommu" for DRA7xx IOMMU instances
      9- ti,hwmods  : Name of the hwmod associated with the IOMMU instance
     10- reg        : Address space for the configuration registers
     11- interrupts : Interrupt specifier for the IOMMU instance
     12- #iommu-cells : Should be 0. OMAP IOMMUs are all "single-master" devices,
     13                 and needs no additional data in the pargs specifier. Please
     14                 also refer to the generic bindings document for more info
     15                 on this property,
     16                     Documentation/devicetree/bindings/iommu/iommu.txt
     17
     18Optional properties:
     19- ti,#tlb-entries : Number of entries in the translation look-aside buffer.
     20                    Should be either 8 or 32 (default: 32)
     21- ti,iommu-bus-err-back : Indicates the IOMMU instance supports throwing
     22		          back a bus error response on MMU faults.
     23- ti,syscon-mmuconfig : Should be a pair of the phandle to the DSP_SYSTEM
     24                        syscon node that contains the additional control
     25                        register for enabling the MMU, and the MMU instance
     26                        number (0-indexed) within the sub-system. This property
     27                        is required for DSP IOMMU instances on DRA7xx SoCs. The
     28                        instance number should be 0 for DSP MDMA MMUs and 1 for
     29                        DSP EDMA MMUs.
