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