21 Lets take an example where we have a foo board with the following base tree::
23     ---- foo.dts ---------------------------------------------------------------
24 	/* FOO platform */
25 	/dts-v1/;
27 		compatible = "corp,foo";
39     ---- foo.dts ---------------------------------------------------------------
41 The overlay bar.dts,
44     ---- bar.dts - overlay target location by label ----------------------------
45 	/dts-v1/;
48 		/* bar peripheral */
49 		bar {
50 			compatible = "corp,bar";
54     ---- bar.dts ---------------------------------------------------------------
56 when loaded (and resolved as described in [1]) should result in foo+bar.dts::
58     ---- foo+bar.dts -----------------------------------------------------------
59 	/* FOO platform + bar peripheral */
61 		compatible = "corp,foo";
72 			/* bar peripheral */
73 			bar {
74 				compatible = "corp,bar";
79     ---- foo+bar.dts -----------------------------------------------------------
81 As a result of the overlay, a new device node (bar) has been created
82 so a bar platform device will be registered and if a matching device driver
85 If the base DT was not compiled with the -@ option then the "&ocp" label
91 The above bar.dts example modified to use target path syntax is::
93     ---- bar.dts - overlay target location by explicit path --------------------
94 	/dts-v1/;
97 		/* bar peripheral */
98 		bar {
99 			compatible = "corp,bar";
103     ---- bar.dts ---------------------------------------------------------------
