+Freescale Security Controller (SCC)
+
+Required properties:
+- compatible : Should be "fsl,imx25-scc".
+- reg : Should contain register location and length.
+- interrupts : Should contain interrupt numbers for SCM IRQ and SMN IRQ.
+- interrupt-names : Should specify the names "scm" and "smn" for the
+ SCM IRQ and SMN IRQ.
+- clocks: Should contain the clock driving the SCC core.
+- clock-names: Should be set to "ipg".
+
+Example:
+
+ scc: crypto@53fac000 {
+ compatible = "fsl,imx25-scc";
+ reg = <0x53fac000 0x4000>;
+ clocks = <&clks 111>;
+ clock-names = "ipg";
+ interrupts = <49>, <50>;
+ interrupt-names = "scm", "smn";
+ };
