| 33 | When compatible with the generic version, nodes must list the |
| 34 | SoC-specific version corresponding to the platform first followed by the |
| 35 | generic version. |

| 43 | |
| 44 | Note: Each enabled SCIx UART should have an alias correctly numbered in the |
| 45 | "aliases" node. |
| 46 | |
| 47 | Example: |
| 48 | aliases { |
| 49 | serial0 = &scifa0; |
| 50 | }; |
