output. Additionally, the device trees are populated into the sysroot for
access via the sysroot from within other recipes.
By default, all device tree sources located in :term:`DT_FILES_PATH` directory
are compiled. To select only particular sources, set :term:`DT_FILES` to
a space-separated list of files (relative to :term:`DT_FILES_PATH`). For
convenience, both ``.dts`` and ``.dtb`` extensions can be used.
An extra padding is appended to non-overlay device trees binaries. This
can typically be used as extra space for adding extra properties at boot time.
The padding size can be modified by setting ``DT_PADDING_SIZE`` to the desired
size, in bytes.
