It lists being able to do 4k30, therefore it's on 4 lanes. If you drop the 4lane override from the dtoverlay line, then I expect it to drop to max 15fps.By creating cam_helper_imx258.cpp from cam_helper_imx219.cpp, I can operate IMX258 module on RPi5 now.
Thank you very much.
--list-cameras shows 4208x3120 30fps by dtoverlay=imx258,4lane in config.txt but I'm not sure it is really in 4lane mode.
(How to check it?)
If you want to check via device tree, then use "xxd" ("sudo apt install xxd" if not already present) with "xxd /proc/device-tree/axi/pcie@120000/rp1/i2c@80000/imx258@10" and it should list lanes 1, 2, 3, and 4 if on 4 lanes. (That /proc/device-tree path is copied from the output of "libcamera-hello --list-cameras". I may have made typos in copying it from your image)
