+Deferred initialization
+***********************
+
+Initialization of devices can also be deferred to a later time. In this case,
+the device is not automatically initialized by Zephyr at boot time. Instead,
+the device is initialized when the application calls :c:func:`device_init`.
+To defer a device driver initialization, add the property ``zephyr,deferred-init``
+to the associated device node in the DTS file. For example:
+
+.. code-block:: devicetree
+
+ / {
+ a-driver@40000000 {
+ reg = <0x40000000 0x1000>;
+ zephyr,deferred-init;
+ };
+ };
