+* Marvell Orion SATA
+
+Required Properties:
+- compatibility : "marvell,orion-sata"
+- reg           : Address range of controller
+- interrupts    : Interrupt controller is using
+- nr-ports      : Number of SATA ports in use.
+
+Example:
+
+        sata@80000 {
+                compatible = "marvell,orion-sata";
+                reg = <0x80000 0x5000>;
+                interrupts = <21>;
+                nr-ports = <2>;
+        }
