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.
|

|
|
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.
