*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>;
