Right ... "instead" is significant..." The only time you'd do nything like that is if the PCI bus interface is nothing more than a bridge to some native bus, and so the driver only uses PCI for enumeration and power management. Then you might have two drivers, and make e.g. a PCI registration *IN ADDITION* to one for the platform bus -- for different drivers. The PCI device would embed a platform device; and each would have its own driver. See for example sl811-hcd, which is a platform driver, but also supports a PCMCIA-bridged config (I forget the name of that bridged driver.) In such a case the "real" driver might be the platform driver (used where-ever that chip is found), but when hooked up to a PCMCIA or PCI bus, it'd have to use other bus glue to talk to the rest of the system; different wiring. Such configurations aren't common ones, but when the device is bridged like that, it's easier to split the "real" and "bus glue" drivers than to integrate the bridging with an instance of the real driver (which must also run without PCI or whatever the bridging bus happens to be. - Dave > -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
