+OMAP2+ IOMMU
+
+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-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
+
+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.
+
+Example:
+	/* OMAP3 ISP MMU */
+	mmu_isp: mmu@480bd400 {
+		compatible = "ti,omap2-iommu";
+		reg = <0x480bd400 0x80>;
+		interrupts = <24>;
