| This enables DMA driven transactions for the I2C peripheral. |
| DMA driven mode requires fewer interrupts to handle the |
| transaction and ensures that high speed modes are not delayed |
| by data reloading. |

| Timeout in milliseconds used for each I2C transfer. |
| 0 means that the driver should use the K_FOREVER value, |
| i.e. it should wait as long as necessary. |
