+Dynamic devices
+---------------
+
+Certain devices may require support for runtime attachment and
+detachment (hot-plugging, essentially).
+
+Optional properties:
+ - dynamic: Boolean; indicates that the device's status may change at
+   runtime.
+
+Example:
+&spi1 {
+	      compatible = "name";
+	      status = "reserved";
+	      ...
+	      dynamic;
+};
