How to use kernel mainline for jetson nano?

[OKOK98]

On the kernel mainline at this link linux/arch/arm/boot/dts/nvidia at master · torvalds/linux · GitHub, I don’t see the device tree for the Jetson Nano. I would like to ask if the Jetson Nano will not use the kernel mainline and only use kernel 4.9 from nvidia. But I heard that the Jetson is at its End of Life (EOF). This means it will no longer receive any support or software upgrades

Do you know any way to use kernel 5.10 or 4.x for the Jetson Nano?

This would be without guarantee, and might not work at all, but I did see this which you might be interested in:

All I did was this: edit etc/apt/sources.list.d/nvidia-l4t-apt-source.list to point to the 35.1 repo (just change the version to r35.1 in both lines) sudo apt update sudo apt dist-upgrade *****@jetson:~$ cat /etc/apt/sources.list.d/nvidia-l4t-apt-source.list deb https://repo.download.nvidia.com/jetson/common r35.1 main deb https://repo.download.nvidia.com/jetson/t210 r35.1 main
