If we have a device tree, we should use it. It sounds like you want to add the equivalent of usb_autopm_get/set_device() and usb_autopm_get/set_interface() into the driver model. But it would not be appropriate, since other subsystems don't have the same kinds of runtime power levels as USB does. There may be no way of getting around the need for specialized communication methods between subsystems for runtime PM.
