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 >;
|
|
|
|
};
