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

26     description: |
27       The default display timing is the one specified as native-mode.
28       If no native-mode is specified then the first node is assumed
29       to be the native mode.
