- * terminating item.

- * @param blob		FDT blob to use
- * @param node		Node to look at
- * @param prop_name	Node property name
- * @param gpio		Array of gpio elements to fill from FDT. This will be
- *			untouched if either 0 or an error is returned
- * @param max_count	Maximum number of elements allowed
- * @return number of GPIOs read if ok, -FDT_ERR_BADLAYOUT if max_count would
- * be exceeded, or -FDT_ERR_NOTFOUND if the property is missing.
