-* ARM SMMUv3 Architecture Implementation
-
-The SMMUv3 architecture is a significant departure from previous
-revisions, replacing the MMIO register interface with in-memory command
-and event queues and adding support for the ATS and PRI components of
-the PCIe specification.
-
-** SMMUv3 required properties:
-
-- compatible        : Should include:
-
-                      * "arm,smmu-v3" for any SMMUv3 compliant
-                        implementation. This entry should be last in the
-                        compatible list.
-
-- reg               : Base address and size of the SMMU.
-
-- interrupts        : Non-secure interrupt list describing the wired
-                      interrupt sources corresponding to entries in
-                      interrupt-names. If no wired interrupts are
-                      present then this property may be omitted.
-
-- interrupt-names   : When the interrupts property is present, should
-                      include the following:
-                      * "eventq"    - Event Queue not empty
-                      * "priq"      - PRI Queue not empty
-                      * "cmdq-sync" - CMD_SYNC complete
-                      * "gerror"    - Global Error activated
-                      * "combined"  - The combined interrupt is optional,
-				      and should only be provided if the
-				      hardware supports just a single,
-				      combined interrupt line.
-				      If provided, then the combined interrupt
-				      will be used in preference to any others.
-
-- #iommu-cells      : See the generic IOMMU binding described in
-                        devicetree/bindings/pci/pci-iommu.txt
-                      for details. For SMMUv3, must be 1, with each cell
-                      describing a single stream ID. All possible stream
-                      IDs which a device may emit must be described.
-
-** SMMUv3 optional properties:
-
-- dma-coherent      : Present if DMA operations made by the SMMU (page
-                      table walks, stream table accesses etc) are cache
-                      coherent with the CPU.
-
-                      NOTE: this only applies to the SMMU itself, not
-                      masters connected upstream of the SMMU.
-
-- msi-parent        : See the generic MSI binding described in
-                        devicetree/bindings/interrupt-controller/msi.txt
-                      for a description of the msi-parent property.
-
-- hisilicon,broken-prefetch-cmd
-                    : Avoid sending CMD_PREFETCH_* commands to the SMMU.
-
-- cavium,cn9900-broken-page1-regspace
-                    : Replaces all page 1 offsets used for EVTQ_PROD/CONS,
-		      PRIQ_PROD/CONS register access with page 0 offsets.
-		      Set for Cavium ThunderX2 silicon that doesn't support
-		      SMMU page1 register space.

-** Example
-
-        smmu@2b400000 {
-                compatible = "arm,smmu-v3";
-                reg = <0x0 0x2b400000 0x0 0x20000>;
-                interrupts = <GIC_SPI 74 IRQ_TYPE_EDGE_RISING>,
-                             <GIC_SPI 75 IRQ_TYPE_EDGE_RISING>,
-                             <GIC_SPI 77 IRQ_TYPE_EDGE_RISING>,
-                             <GIC_SPI 79 IRQ_TYPE_EDGE_RISING>;
-                interrupt-names = "eventq", "priq", "cmdq-sync", "gerror";
-                dma-coherent;
-                #iommu-cells = <1>;
-                msi-parent = <&its 0xff0000>;
