+CC2520 IEEE 802.15.4 Compatible Radio
+
+Required properties:
+	- compatible:		should be "ti,cc2520"
+	- spi-max-frequency:	maximal bus speed (8000000), should be set to 4000000 depends
+				sync or async operation mode
+	- reg:			the chipselect index
+	- mode:			SPI mode
+Example:
+
+	cc2520@0 {
+		compatible = "ti,cc2520";
+		reg = <0>;
+		spi-max-frequency = <4000000>;
+		mode = <1>;
+
+		pinctrl-names = "default";
+		pinctrl-0 = <&cc2520_cape_pins>;	/*GPIO pin muxing details*/
+
+		fifo-gpio = <&gpio1 18 0>;
+		fifop-gpio = <&gpio1 19 0>;
+		sfd-gpio = <&gpio1 13 0>;
+		cca-gpio = <&gpio1 16 0>;
+		vreg-gpio = <&gpio0 31 0>;
+		reset-gpio = <&gpio1 12 0>;
