-Howto use the configfs overlay interface.
-
-A device-tree configfs entry is created in /config/device-tree/overlays
-and and it is manipulated using standard file system I/O.
-Note that this is a debug level interface, for use by developers and
-not necessarily something accessed by normal users due to the
-security implications of having direct access to the kernel's device tree.
-
-* To create an overlay you mkdir the directory:
-
-	# mkdir /config/device-tree/overlays/foo
-
-* Either you echo the overlay firmware file to the path property file.
-
-	# echo foo.dtbo >/config/device-tree/overlays/foo/path
-
-* Or you cat the contents of the overlay to the dtbo file
-
-	# cat foo.dtbo >/config/device-tree/overlays/foo/dtbo
-
-The overlay file will be applied, and devices will be created/destroyed
-as required.
-
-To remove it simply rmdir the directory.
-
-	# rmdir /config/device-tree/overlays/foo
-
-The rationalle of the dual interface (firmware & direct copy) is that each is
-better suited to different use patterns. The firmware interface is what's
-intended to be used by hardware managers in the kernel, while the copy interface
-make sense for developers (since it avoids problems with namespaces).
