+# This bbclass implements device tree compliation for user provided device tree
+# sources. The compilation of the device tree sources is the same as the kernel
+# device tree compilation process, this includes being able to include sources
+# from the kernel such as soc dtsi files or header files such as gpio.h. In
+# addition to device trees this bbclass also handles compilation of device tree
+# overlays.
+#
+# The output of this class behaves similar to how kernel-devicetree.bbclass
+# operates in that the output files are installed into /boot/devicetree.
+# However this class on purpose separates the deployed device trees into the
+# 'devicetree' subdirectory. This prevents clashes with the kernel-devicetree
+# output. Additionally the device trees are populated into the sysroot for
+# access via the sysroot from within other recipes.
