+* Allwinner Security System found on A20 SoC
+
+Required properties:
+- compatible : Should be "allwinner,sun4i-a10-crypto".
+- reg: Should contain the Security System register location and length.
+- interrupts: Should contain the IRQ line for the Security System.
+- clocks : List of clock specifiers, corresponding to ahb and ss.
+- clock-names : Name of the functional clock, should be
+ * "ahb" : AHB gating clock
+ * "mod" : SS controller clock
+
+Example:
+ crypto: crypto-engine@01c15000 {
+ compatible = "allwinner,sun4i-a10-crypto";
+ reg = <0x01c15000 0x1000>;
+ interrupts = <GIC_SPI 86 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&ahb_gates 5>, <&ss_clk>;
+ clock-names = "ahb", "mod";
+ };
