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.

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.
