We need to change the AMBA bus so it does something better than what it does now and work out a good way to roll this out. The more I think about this the less convinced I am that AMBA should have regualtor support in the bus itself at all.
How else does it power up the peripheral to read out the IDs? You can't bind a driver until you've read the ID, which implies that the bus layer needs to have regulator support to turn the power on.
