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-iommu" for DRA7xx IOMMU instances 8- ti,hwmods : Name of the hwmod associated with the IOMMU instance 9- reg : Address space for the configuration registers 10- interrupts : Interrupt specifier for the IOMMU instance 11- #iommu-cells : Should be 0. OMAP IOMMUs are all "single-master" devices, 12 and needs no additional data in the pargs specifier. Please 13 also refer to the generic bindings document for more info 14 on this property, 15 Documentation/devicetree/bindings/iommu/iommu.txt 16 17Optional properties: 18- ti,#tlb-entries : Number of entries in the translation look-aside buffer. 19 Should be either 8 or 32 (default: 32) 20- ti,iommu-bus-err-back : Indicates the IOMMU instance supports throwing 21 back a bus error response on MMU faults. 22 23Example: 24 /* OMAP3 ISP MMU */ 25 mmu_isp: mmu@480bd400 { 26 #iommu-cells = <0>; 27 compatible = "ti,omap2-iommu"; 28 reg = <0x480bd400 0x80>; 29 interrupts = <24>; 30 ti,hwmods = "mmu_isp"; 31 ti,#tlb-entries = <8>; 32 }; 33
