+Marvell Cryptographic Engines And Security Accelerator
+
+Required properties:
+- 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>;
+ reg-names = "regs";
+ interrupts = <22>;
+ marvell,crypto-srams = <&crypto_sram>;
+ marvell,crypto-sram-size = <0x600>;
+ };
