1 *CC2520 IEEE 802.15.4 Compatible Radio*
2
3 Required 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
16 Optional properties:
17 - amplified: include if the CC2520 is connected to a CC2591 amplifier

20 cc2520@0 {
21 compatible = "ti,cc2520";
22 reg = <0>;
23 spi-max-frequency = <4000000>;
24 amplified;
25 pinctrl-names = "default";
26 pinctrl-0 = <&cc2520_cape_pins>;
