1*CC2520 IEEE 802.15.4 Compatible Radio*
2
3Required properties:
4	- compatible: 		should be "ti,cc2520"
5	- spi-max-frequency:	maximal bus speed (8000000), should be set to 4000000 depends
6				sync or async operation mode
7	- reg:			the chipselect index
8	- pinctrl-0: 		pin control group to be used for this controller.
9	- pinctrl-names: 	must contain a "default" entry.
10	- fifo-gpio:		GPIO spec for the FIFO pin
11	- fifop-gpio:		GPIO spec for the FIFOP pin
12	- sfd-gpio:		GPIO spec for the SFD pin
13	- cca-gpio:		GPIO spec for the CCA pin
14	- vreg-gpio:		GPIO spec for the VREG pin
15	- reset-gpio:		GPIO spec for the RESET pin

17	cc2520@0 {
18		compatible = "ti,cc2520";
19		reg = <0>;
20		spi-max-frequency = <4000000>;
21		pinctrl-names = "default";
22		pinctrl-0 = <&cc2520_cape_pins>;
23		fifo-gpio = <&gpio1 18 0>;
24		fifop-gpio = <&gpio1 19 0>;
25		sfd-gpio = <&gpio1 13 0>;
26		cca-gpio = <&gpio1 16 0>;
27		vreg-gpio = <&gpio0 31 0>;
