Where is the Device Tree in the source tree?

Just did a build following the steps in GitHub - SolidRun/lx2160a_build: Scripts to build basic images for LX2160A COM express type 7 modules
Can anyone tell me where I can find the device tree for this board?

Thanks!

The device-tree is added to the NXP BSP kernel through the patches in the patches/linux sub-directory. They get applied to the build/linux git repository and are found under the arch/arm64/boot/dts/freescale/ directory.
