where can i find the patched kernel source code for s905x4 (sc2), i have checked all branches of your linux repository, but i cant find the dts for s905x4 (sc2)?

The SC2/S905X4 patches and DTS files are not fully available in the public Linux repository yet. As stated in the README:

"The kernel is based on the mainline kernel source (kernel.org), only SC2 and S4 support needs some extra patches."

and also:

"Other sources and build scripts are not available at this moment. Not that I don't want to share, but because they are messy and I don't have the time to clean them up."

So devmfc may be using local/private patches that are not present in the public kernel tree or in the debian-on-amlogic repository.

However, the DTBs are included in the released images. You can extract them from a Debian/Ubuntu image from the releases page:
https://github.com/devmfc/debian-on-amlogic/releases

Example:

unxz image.img.xz

sudo losetup --show -fP image.img

Take note of the created loop device (example: /dev/loop0).

Then:

sudo mkdir -p /mnt/devmfc-image-boot
sudo mount /dev/loop0p1 /mnt/devmfc-image-boot

The DTBs are usually located in something like:

/mnt/devmfc-image-boot/dtb-6.18.26-meson64/amlogic

You can search for SC2 DTBs with:

find /mnt/devmfc-image-boot/dtb-6.18.26-meson64/amlogic | grep -i sc2

Copy the DTB you want, then unmount everything:

sudo umount /mnt/devmfc-image-boot
sudo losetup -d /dev/loop0

If you want to inspect or modify the DTB, convert it back to DTS using dtc:

dtc -I dtb -O dts -o output.dts input.dtb
