- #interconnect-cells: required by the interconnect framework. Please note that #interconnect-cells is always zero and node IDs are not hardcoded anywhere. The above-mentioned parent-child relation in devfreq means that there is a shared power line ('devfreq' property). The 'parent' property only signifies an interconnect connection.
