+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>;
+ };
