1Inside Secure SafeXcel cryptographic engine
2
3Required properties:
4- compatible: Should be "inside-secure,safexcel-eip197b",
5	      "inside-secure,safexcel-eip197d" or
6              "inside-secure,safexcel-eip97ies".
7- reg: Base physical address of the engine and length of memory mapped region.
8- interrupts: Interrupt numbers for the rings and engine.
9- interrupt-names: Should be "ring0", "ring1", "ring2", "ring3", "eip", "mem".
10
11Optional properties:
12- clocks: Reference to the crypto engine clocks, the second clock is
13          needed for the Armada 7K/8K SoCs.
14- clock-names: mandatory if there is a second clock, in this case the
15               name must be "core" for the first clock and "reg" for
16               the second one.

18Backward compatibility:
19Two compatibles are kept for backward compatibility, but shouldn't be used for
20new submissions:
21- "inside-secure,safexcel-eip197" is equivalent to
22  "inside-secure,safexcel-eip197b".
23- "inside-secure,safexcel-eip97" is equivalent to
24  "inside-secure,safexcel-eip97ies".

26Example:

28	crypto: crypto@800000 {
29		compatible = "inside-secure,safexcel-eip197b";
30		reg = <0x800000 0x200000>;
31		interrupts = <GIC_SPI 34 IRQ_TYPE_LEVEL_HIGH>,
32			     <GIC_SPI 54 IRQ_TYPE_LEVEL_HIGH>,
33			     <GIC_SPI 55 IRQ_TYPE_LEVEL_HIGH>,
34			     <GIC_SPI 56 IRQ_TYPE_LEVEL_HIGH>,
35			     <GIC_SPI 57 IRQ_TYPE_LEVEL_HIGH>,
36			     <GIC_SPI 58 IRQ_TYPE_LEVEL_HIGH>;
37		interrupt-names = "mem", "ring0", "ring1", "ring2", "ring3",
38				  "eip";
39		clocks = <&cpm_syscon0 1 26>;
