Which file should I modify to enable the use of a 2-lane display instead of a 4-lane one through the DP interface?
Please follow the devkit 4 lane design.
Can I achieve this by modifying the device tree, given that the current hardware design is based on 2 lanes?
That is not tested. We cannot guarantee that could work fine.
Can you help me confirm which file under the jakku directory contains the configuration for DP? I’ll try to make some modifications.
You can grep “nvdisplay”. There should be file like “3668-disp.dtsi”
I found nvdisplay, but I couldn’t locate where to disable the two lanes. Can I disable the two lanes in the device tree, or do I need to disable them in the driver file?
Try to read kernel/nvidia/Documentation/devicetree/bindings/video/nvidia,tegra186-dp.txt
There is a configuration “nvidia,lanes” but not in use for long time.
