+ * fdt_for_each_subnode - iterate over all subnodes of a parent
+ *
+ * This is actually a wrapper around a for loop and would be used like so:
+ *
+ *	fdt_for_each_subnode(fdt, node, parent) {
+ *		...
+ *		use node
+ *		...
+ *	}
+ *
+ * Note that this is implemented as a macro and node is used as iterator in
+ * the loop. It should therefore be a locally allocated variable. The parent
+ * variable on the other hand is never modified, so it can be constant or
+ * even a literal.
+ *
+ * @fdt:	FDT blob (const void *)
+ * @node:	child node (int)
+ * @parent:	parent node (int)
