To support path tag in icc-rpm driver, the "#interconnect-cells" property is updated as enumerate values: 1 or 2. Setting to 1 means it is compatible with old DT binding that interconnect path only contains node id; if set to 2 for "#interconnect-cells" property, then the second specifier is used as a tag (e.g. vote for which buckets).
