| reset-gpios: |
| type: phandle-array |
| required: false |
| description: | |
| GPIO connected to the modem's NRESET signal. |
| |
| This signal is open-drain, active-low as interpreted by the |
| modem. |
| |
| busy-gpios: |
| type: phandle-array |
| required: false |
| description: | |
| GPIO connected to the modem's BUSY signal. |
| |
| antenna-enable-gpios: |
| type: phandle-array |
| required: false |
| description: | |
| Antenna power enable pin. |
| |
| tx-enable-gpios: |
| type: phandle-array |
| required: false |
| description: | |
| Antenna switch TX enable GPIO. If set, the driver tracks the |
| state of the radio and controls the RF switch. |
| |
| rx-enable-gpios: |
| type: phandle-array |
| required: false |
| description: | |
| Antenna switch RX enable GPIO. If set, the driver tracks the |
| state of the radio and controls the RF switch. |
| |
| dio1-gpios: |
| type: phandle-array |
| required: false |
| description: | |
| GPIO connected to DIO1. This GPIO will be used as a generic |
| IRQ line from the chip. |
| |
| dio2-tx-enable: |
| type: boolean |
| required: false |
| description: | |
| Use DIO2 to drive an RF switch selecting between the TX and RX |
| paths. When enabled, DIO2 goes high when the chip is |
| transmitting. |
| |
| dio3-tcxo-voltage: |
| type: int |
| required: false |
| description: | |
| TCXO supply voltage controlled by DIO3 if present. |
| |
| See constants in dt-bindings/lora/sx126x.h. |
| |
| tcxo-power-startup-delay-ms: |
| type: int |
| required: false |
| description: | |
| Startup delay to let the TCXO stabilize after TCXO power on. |
