Arm TrustZone CryptoCell cryptographic accelerators
Required properties:
- compatible: must be "arm,cryptocell-712-ree".
- reg: shall contain base register location and length.
Typically length is 0x10000.
- interrupts: shall contain the interrupt for the device.
Optional properties:
- interrupt-parent: can designate the interrupt controller the
device interrupt is connected to, if needed.
- clocks: may contain the clock handling the device, if needed.
- power-domains: may contain a reference to the PM domain, if applicable.
Examples:
Zynq FPGA device
----------------
arm_cc7x: arm_cc7x@80000000 {
compatible = "arm,cryptocell-712-ree";
interrupt-parent = <&intc>;
interrupts = < 0 30 4 >;
reg = < 0x80000000 0x10000 >;
};
