Required properties:



- 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@2000000000 {

		compatible = "arm,ccn-504";

		reg = <0x20 0x00000000 0 0x1000000>;

		interrupts = <0 181 4>;

	};
