This 6 interface is usually available on Wifi/Bluetooth/LTE modules to 7 interact with each other when sharing same antenna. This prevents 8 any collisions between transmissions from different modules. The grant 9 signal should signal that the external transceiver/module is not 10 transmitting. Therefore you are free to perform any TX operations as 11 required. When grant pin becomes inactive then you have time to 12 finish all of the ongoing TX operations before the external 13 transceiver begins their transmission. This is specified by the 14 grant-delay-us property. 15 16compatible: "gpio-radio-coex" 17 18include: base.yaml 19 20properties: 21 grant-gpios: 22 type: phandle-array 23 required: true 24 description: | 25 GPIO input from the external transceiver 26 27 grant-delay-us: 28 type: int 29 required: true 30 description: | 31 Delay after assertion for the external transceiver operation 32
