+* Freescale 85xx RAID Engine nodes
+
+RAID Engine nodes are defined to describe on-chip RAID accelerators.  Each RAID
+Engine should have a separate node.
+
+Supported chips:
+P5020, P5040
+
+Required properties:
+
+- compatible:   Should contain "fsl,raideng-v1.0" as the value
+                This identifies RAID Engine block. 1 in 1.0 represents
+                major number whereas 0 represents minor number. The
+                version matches the hardware IP version.
+- reg:          offset and length of the register set for the device
+- ranges:       standard ranges property specifying the translation
+                between child address space and parent address space
+
+Example:
+        /* P5020 */
+        raideng: raideng@320000 {
+                compatible = "fsl,raideng-v1.0";
+                #address-cells = <1>;
+                #size-cells = <1>;
+                reg     = <0x320000 0x10000>;
+                ranges  = <0 0x320000 0x10000>;
+        };
+
+
+There must be a sub-node for each job queue present in RAID Engine
+This node must be a sub-node of the main RAID Engine node
+
+- compatible:   Should contain "fsl,raideng-v1.0-job-queue" as the value
+                This identifies the job queue interface
+- reg:          offset and length of the register set for job queue
+- ranges:       standard ranges property specifying the translation
+                between child address space and parent address space
+
+Example:
+        /* P5020 */
+        raideng_jq0@1000 {
+                compatible = "fsl,raideng-v1.0-job-queue";
+                reg        = <0x1000 0x1000>;
+                ranges     = <0x0 0x1000 0x1000>;
+        };
+
+
+There must be a sub-node for each job ring present in RAID Engine
+This node must be a sub-node of job queue node
+
+- compatible:   Must contain "fsl,raideng-v1.0-job-ring" as the value
+                This identifies job ring. Should contain either
+                "fsl,raideng-v1.0-hp-ring" or "fsl,raideng-v1.0-lp-ring"
+                depending upon whether ring has high or low priority
+- reg:          offset and length of the register set for job ring
+- interrupts:   interrupt mapping for job ring IRQ
+
+Optional property:
+
+- fsl,liodn:    Specifies the LIODN to be used for Job Ring. This
+                property is normally set by firmware. Value
+                is of 12-bits which is the LIODN number for this JR.
+                This property is used by the IOMMU (PAMU) to distinquish
+                transactions from this JR and than be able to do address
+                translation & protection accordingly.
+
+Example:
+        /* P5020 */
+        raideng_jq0@1000 {
+                compatible = "fsl,raideng-v1.0-job-queue";
+                reg        = <0x1000 0x1000>;
+                ranges     = <0x0 0x1000 0x1000>;
+
+                raideng_jr0: jr@0 {
+                        compatible = "fsl,raideng-v1.0-job-ring", "fsl,raideng-v1.0-hp-ring";
+                        reg        = <0x0 0x400>;
+                        interrupts = <139 2 0 0>;
+                        interrupt-parent = <&mpic>;
+                        fsl,liodn = <0x41>;
+                };
+        };
