+Marvell Cryptographic Engines And Security Accelerator
+
+Required properties:
+- compatible : should be "marvell,orion-crypto"
+- reg : base physical address of the engine and length of memory mapped
+        region, followed by base physical address of sram and its memory
+        length
+- reg-names : "regs" , "sram";
+- interrupts : interrupt number
+
+Examples:
+
+        crypto@30000 {
+                compatible = "marvell,orion-crypto";
+                reg = <0x30000 0x10000>,
+                      <0x4000000 0x800>;
+                reg-names = "regs" , "sram";
+                interrupts = <22>;
+                status = "okay";
+        };
