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.
properties:
$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.
