v1:
Initial version wast .txt file
v2:
From txt to yaml file format
v3:
* Andrzej Hajda review comments incorporated
dual port lvds implemented
* Laurent Pinchart review comments incorporated
dsi lanes property removed and it is dynamically
picked from the dsi ports
VESA/JEIDA format picked from panel-lvds dts

Fix indent. One of the '}' is indented one space too much.

What is the purpose with the second example?
Does it explain the binding better in some way?
The examples shall help understanding the binding, not help
understanding the HW. The latter is the role of the binding.

If this example is kept then fix indent of '}'.

sam,
I rechecked, but did not find any indents are too spaced.
This is taken from a working dts tree.
I had given two examples for a purpose. One for single lvds
configuration single link mode,
another is for dual lvds configurations dual-link mode and port mappings.
