|
|
|
|
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
|
|
Optional properties:
|
|
- amplified: include if the CC2520 is connected to a CC2591 amplifier
|
|
|
|
Example:
|
|
cc2520@0 {
