  1. *CC2520 IEEE 802.15.4 Compatible Radio*
  2. Required properties:
  3. - compatible: should be "ti,cc2520"
  4. - spi-max-frequency: maximal bus speed (8000000), should be set to 4000000 depends
  5. sync or async operation mode
  6. - reg: the chipselect index
  7. - pinctrl-0: pin control group to be used for this controller.
  8. - pinctrl-names: must contain a "default" entry.
  9. - fifo-gpio: GPIO spec for the FIFO pin
  10. - fifop-gpio: GPIO spec for the FIFOP pin
  11. - sfd-gpio: GPIO spec for the SFD pin
  12. - cca-gpio: GPIO spec for the CCA pin
  13. - vreg-gpio: GPIO spec for the VREG pin
  14. - reset-gpio: GPIO spec for the RESET pin
  15. Optional properties:
  16. - amplified: include if the CC2520 is connected to a CC2591 amplifier
  17. Example:
  18. cc2520@0 {
  19. compatible = "ti,cc2520";
  20. reg = <0>;
  21. spi-max-frequency = <4000000>;
  22. amplified;
  23. pinctrl-names = "default";
  24. pinctrl-0 = <&cc2520_cape_pins>;
  25. fifo-gpio = <&gpio1 18 0>;
  26. fifop-gpio = <&gpio1 19 0>;
  27. sfd-gpio = <&gpio1 13 0>;
  28. cca-gpio = <&gpio1 16 0>;
  29. vreg-gpio = <&gpio0 31 0>;
  30. reset-gpio = <&gpio1 12 0>;
