+* 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
+
+Optional properties:
+ - resets : phandle + reset specifier pair
+ - reset-names : must contain "ahb"
