+Arm TrustZone CryptoCell cryptographic engine
+
+Required properties:
+- compatible: Should be one of: "arm,cryptocell-712-ree",
+  "arm,cryptocell-710-ree" or "arm,cryptocell-630p-ree".
+- reg: Base physical address of the engine and length of memory mapped region.
+- interrupts: Interrupt number for the device.
+
+Optional properties:
+- clocks: Reference to the crypto engine clock.
+- dma-coherent: Present if dma operations are coherent.
+
+Examples:
+
+       arm_cc712: crypto@80000000 {
+               compatible = "arm,cryptocell-712-ree";
+               interrupt-parent = <&intc>;
+               interrupts = < 0 30 4 >;
+               reg = < 0x80000000 0x10000 >;
+
+       };
