+Required properties:
+ - compatible: should be "ti,cc2520"
+ - spi-max-frequency: maximal bus speed, should be set to 4000000 depends
+ sync or async operation mode
+ - reg: the chipselect index
+
+Optional properties:
+ - fifo-gpio: GPIO spec for the fifo pin
+ - fifop-gpio: GPIO spec for the fifop pin
+ - sfd-gpio: GPIO spec for the sfd pin
