Arm TrustZone CryptoCell cryptographic engine



Required properties:

- compatible: Should be "arm,cryptocell-712-ree".

- reg: Base physical address of the engine and length of memory mapped region.

- interrupts: Interrupt number for the device.



Optional properties:

- interrupt-parent: The phandle for the interrupt controller that services

  interrupts for this device.

- 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 >;



       };
