I need an help on USB vs PM. I'm working on a embedded platform with USB Host Controller. There is an EHCI with a Companion OHCI and both work fine. Now I would add the PM support. Until now both the host controller are on the 'platform_bus' therefore they seem independent. Is this configuration ok or I have to declare a kind of relationship between the host controller (and if so which one)? Regards Francesco
