-
-- compatible: (standard compatible string) should be one of:
-	"arm,ccn-502"
-	"arm,ccn-504"
-	"arm,ccn-508"
-	"arm,ccn-512"
-
-- reg: (standard registers property) physical address and size
-	(16MB) of the configuration registers block
-
-- interrupts: (standard interrupt property) single interrupt
-	generated by the control block

-Example:
-
-	ccn at 2000000000 {
-		compatible = "arm,ccn-504";
-		reg = <0x20 0x00000000 0 0x1000000>;
