That's how remote wakeup works; it uses the auxiliary well. This, kinda, matches what OMAP tries to do with pad wakeup. Just that pad wakeup sits outside of the device itself. Perhaps we could look into how PCI handles the aux well and take some inspiration from there. Any pointers under drivers/pci/ would be great :-) -- balbi
