+*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
+ - pinctrl-0: pin control group to be used for this controller.
+ - pinctrl-names: must contain a "default" entry.
+ - fifo-gpio: GPIO spec for the FIFO pin
+ - fifop-gpio: GPIO spec for the FIFOP pin
+ - sfd-gpio: GPIO spec for the SFD pin
+ - cca-gpio: GPIO spec for the CCA pin
+ - vreg-gpio: GPIO spec for the VREG pin
+ - reset-gpio: GPIO spec for the RESET pin
+Example:
+ cc2520@0 {
+ compatible = "ti,cc2520";
+ reg = <0>;
+ spi-max-frequency = <4000000>;
+ pinctrl-names = "default";
+ pinctrl-0 = <&cc2520_cape_pins>;
+ 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>;
