Inside Secure SafeXcel cryptographic engine
|
|
|
|
Required properties:
|
|
- compatible: Should be "inside-secure,safexcel-eip197".
|
|
- reg: Base physical address of the engine and length of memory mapped region.
|
|
- interrupts: Interrupt numbers for the rings and engine.
|
|
- interrupt-names: Should be "ring0", "ring1", "ring2", "ring3", "eip", "mem".
|
|
|
|
Optional properties:
|
|
- clocks: Reference to the crypto engine clock.
|
|
- dma-mask: The address mask limitation. Defaults to 64.
|
|
|
|
Example:
|
|
|
|
crypto: crypto@800000 {
|
|
compatible = "inside-secure,safexcel-eip197";
|
|
reg = <0x800000 0x200000>;
|
|
interrupts = <GIC_SPI 34 IRQ_TYPE_LEVEL_HIGH>,
|
|
<GIC_SPI 54 IRQ_TYPE_LEVEL_HIGH>,
|
|
<GIC_SPI 55 IRQ_TYPE_LEVEL_HIGH>,
|
|
<GIC_SPI 56 IRQ_TYPE_LEVEL_HIGH>,
|
|
<GIC_SPI 57 IRQ_TYPE_LEVEL_HIGH>,
|
|
<GIC_SPI 58 IRQ_TYPE_LEVEL_HIGH>;
|
|
interrupt-names = "mem", "ring0", "ring1", "ring2", "ring3",
|
|
"eip";
|
|
clocks = <&cpm_syscon0 1 26>;
|
|
dma-mask = <0xff 0xffffffff>;
|
|
status = "disabled";
|
|
};
