DTC将.dts编译为.dtb的工具。DTC的源代码在目录scripts/dtc目录中
内核使能了设备树。编译内核的时候DTC工具会自动被编译出来，对应于
scripts/dtc/Makefile 中 hostprogs-y := dtc也可以单独安装DTC
sudo apt-get install device-tree-compiler在linux内核的arch/arm/boot/Makefile中。定义了哪些dtb文件会被编译出来，如下
dtb-$(CONFIG_SOC_AM33XX) += \ am335x-lxm.dtb \ am335x-pigoa800.dtb \ am335x-pigoa800-1g.dtb \ am335x-pigoa810.dtb \ am335x-pigoa810-1g.dtb \ am335x-pigoa840.dtb \ am335x-pigoa840-1g.dtb \ am335x-pigoa84x.dtb \ am335x-pigoa84x-1g.dtb \ am335x-pigoa84x-ram1g-nand1g.dtb \ am335x-pigoa84x-ram1g-nand256.dtb \ am335x-pigoa84x-ram512g-nand1g.dtb \ am335x-pigoa84x-ram512-nand256.dtb \ am335x-ieda800-1g.dtb \ am335x-chiliboard.dtb \ am335x-wega-rdk.dtb在linux下，我们可以单独编译设备树
make dtbs反汇编
./scripts/dtc/dtc -I dtb -o dts -o xxx.dts arch/arm/boot/dts/xxx.dtb
