OF_child()  returns  the  phandle value of the first child of the node.  Zero is returned if there are no
       child nodes.

       OF_parent() returns the phandle for the parent of the node.  Zero is returned if node is the root node.

       OF_peer() returns the phandle value of the next sibling of the node.  Zero is returned  if  there  is  no
       sibling node.

       phandle_t node, child;
        ...
       for (child = OF_child(node); child != 0; child = OF_peer(child) {
               ...
