I know I can not take patches without any changelog text.  Maybe other
maintainers are more "lax" :(

thanks,

Okay -- for this one I wasn't sure what to put in the body that wasn't 
basically just duplicating the subject line or the content of the patch, 
but I'll make sure to put something there in the future.

+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;
+};
