The writable status sysfs file enabled by the 'dynamic' DT property
requires CONFIG_OF_DYNAMIC to be useful, but that shouldn't require
dragging in CONFIG_OF_UNITTEST as well.

 	  On some platforms, the device tree can be manipulated at runtime.
-	  While this option is selected automatically on such platforms, you
-	  can enable it manually to improve device tree unit test coverage.
+	  With this option enabled, device tree nodes that are marked with
+	  the "dynamic" property can have their status toggled between
+	  "okay" and "reserved" via sysfs.  This can also be enabled to
+	  increase test coverage with CONFIG_OF_UNITTEST if desired.
