 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
+- compatible: should be one of the following string
+             "marvell,orion-crypto"
+             "marvell,kirkwood-crypto"
+             "marvell,dove-crypto"
+- reg: base physical address of the engine and length of memory mapped
+       region. Can also contain an entry for the SRAM attached to the CESA,
+       but this representation is deprecated and marvell,crypto-srams should
+       be used instead
+- reg-names: "regs". Can contain an "sram" entry, but this representation
+            is deprecated and marvell,crypto-srams should be used instead
+- interrupts: interrupt number
+- clocks: reference to the crypto engines clocks. This property is only
+         required for Dove platforms
+- marvell,crypto-srams: phandle to crypto SRAM definitions
+
+Optional properties:
+- marvell,crypto-sram-size: SRAM size reserved for crypto operations, if not
+                           specified the whole SRAM is used (2KB)
 
 Examples:
 
        crypto@30000 {
                compatible = "marvell,orion-crypto";
-               reg = <0x30000 0x10000>,
-                     <0x4000000 0x800>;
-               reg-names = "regs" , "sram";
+               reg = <0x30000 0x10000>;
+               reg-names = "regs";
                interrupts = <22>;
+               marvell,crypto-srams = <&crypto_sram>;
+               marvell,crypto-sram-size = <0x600>;
                status = "okay";
        };
