There are also conveniences for commonly used zephyr-specific properties of the
``/chosen`` node. (These may also be set in :file:`dts_fixup.h` files for now,
though this mechanism is deprecated.)

The following table documents some commonly used Zephyr-specific chosen nodes.
Often, a chosen node's label property will be used to set the default value of
a Kconfig option which in turn configures a hardware-specific subsystem
setting. This is usually for backwards compatibility in cases when the Kconfig
option predates devicetree support in Zephyr. In other cases, there is no
Kconfig option, and the devicetree node's label property is used directly in
the source code to specify a device name.

acting as a Bluetooth Controller.
