Hi, The easiest way is to add them via patches. You can write a recipe that patch the Linux tree and put it in your meta layer (usually in meta-xxx/recipes-kernel/linux). Then you need to tell Yocto to export the dtb via KERNEL_DEVICETREE variable ( https://www.yoctoproject.org/docs/latest/mega-manual/mega-manual.html#var-KERNEL_DEVICETREE). I usually put this variable in my machine configuration.
