Inside Secure SafeXcel cryptographic engine



Required properties:

- compatible: Should be "inside-secure,safexcel-eip197b",

	      "inside-secure,safexcel-eip197d" or

              "inside-secure,safexcel-eip97ies".

- 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 clocks, the second clock is

          needed for the Armada 7K/8K SoCs.

- clock-names: mandatory if there is a second clock, in this case the

               name must be "core" for the first clock and "reg" for

               the second one.



Backward compatibility:

Two compatibles are kept for backward compatibility, but shouldn't be used for

new submissions:

- "inside-secure,safexcel-eip197" is equivalent to

  "inside-secure,safexcel-eip197b".

- "inside-secure,safexcel-eip97" is equivalent to

  "inside-secure,safexcel-eip97ies".



Example:



	crypto: crypto@800000 {

		compatible = "inside-secure,safexcel-eip197b";

		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>;

	};
