Many modern CODECs have shared resources on chip which must be enabled for portions of the chip to work but which can be disabled at other times in order to achieve power savings. Examples of such resources include power supplies and some internal clocks. Since these widgets are dependencies for the audio path but do not carry audio signals they require slightly different handling to most widgets - they do not contribute to the audio path and so should not be counted as either inputs or outputs during path walks. Cases where one supply provides a supply for another will require additional work. There is also room for more optimisation of the graph walking to avoid repeated checks for the same thing.
