| 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 |
