How do I interface mipi dsi 2-lane with 4-lane displays?

[KAlab.1]

I cannot find compatible displays for this processor.

Usually display panels can be configured for the amount of DSI lanes that would be used.

The number of lanes should be specified as one of the properties in the devicetree.

But check carefully while selecting the display. For example, this one only accepts 3 or 4 as value for the property 'dsi-lanes'

Two lanes a bit design limiting in a world expecting FHD and UHD displays..

[AntonioST]

The datasheet reports:

> LCD-TFT controller, up to 24-bit // RGB888

> – up to WXGA (1366 × 768) @60 fps

Configure the display controller..

Two lanes will limit the total resolution, colour depth and refresh rate.
