We don't have an infrastructure to do this right now. Some ports do this on an ad-hoc basis. The usual needs are to have a DAG relationship between different parts = of the system so you can turn on and tune clocks, as well as power = blocks which may be necessary to power the clock and/or basic-blocks in = the SoC. The latest chips have grown quite complex. Warner
