| Generic representation of Coexistence pin interface for radios. This |
| interface is usually available on Wifi/Bluetooth/LTE modules to |
| interact with each other when sharing the same antenna. This prevents |
| any collisions between transmissions from different modules. The grant |
| signal should signal that the external transceiver/module is not |
| transmitting. Therefore you are free to perform any TX operations as |
| required. When grant pin becomes inactive then you have time to |
| finish all of the ongoing TX operations before the external |
| transceiver begins their transmission. This is specified by the |
| grant-delay-us property. |
