| description: | |
| A display panel may be able to handle several display timings, |
| with different resolutions. |
| The display-timings node makes it possible to specify the timings |
| and to specify the timing that is native for the display. |
| |

| $nodename: |
| const: display-timings |

| native-mode: |
| $ref: /schemas/types.yaml#/definitions/phandle |
| description: | |
| The default display timing is the one specified as native-mode. |
| If no native-mode is specified then the first node is assumed |
| to be the native mode. |
