Yes I think we can make it all automatic. So far it seems that the last missing piece was Linus' suggestion of making it mostly happen using irqchip with calls to pinctrl so consumer drivers may not need to do anything. > > (As result, i2c-mux is not good example, seems:)) > > As such, I think all situations are good examples, because a generic > feature has to work in all cases. Yes we need to support both runtime PM, and more complex cases of sharing pins between devices for example that are not runtime PM related.
