-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";
-	};
