- * Decode a list of GPIOs from an FDT. This creates a list of GPIOs with no
- * 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.
