Hello jnettlet, the patches did the job, I can successfully communicate with the camera with below command:  
`gst-launch-1.0 -v v4l2src device=/dev/video0 ! "video/x-raw,format=YUY2,width=1920,height=1080" ! queue ! imxvideoconvert_g2d ! waylandsink`

Thank you for the given time and effort, you have helped me immensely.

One side note: there are still many errors visible in the dmesg output (see link) related to samsung-hdmi-phy, imx6q-pcie, imx-lcdifv3, sdhci-esdhc-imx, imx-dsp-rproc, imx8-pcie-phy, reg-userspace-consumer and some others. [dmesg output - Pastebin.com](https://pastebin.com/dXWPac51)

I did not have any issue with mentioned components, however, I did not spend any reasonable time with them.

Could they become issue in the future or is this the expected output and can be ignored?

those are EPROBE\_DEFER error messages, which just means that not everything needed for one driver is setup yet, so it should be probed later. They aren’t really errors, but that is how NXP has coded them. Well written drivers will generally special case EPROBE\_DEFER errors as dev\_dbg() rather than dev\_err()

Understood, thank you for explanation.
