Sorry, correction: pm_register() is used for both ISA PnP and non-PnP devices. > Right solution for ISA devices is probably to create an ISA bus in > driver model, and hook such devices there.... Yep. > Alternatively, you might just hang them onto platform bus, in similar > way i8042 uses... This looks easier to implement as a temporary solution until ISA bus is implemented. We know how many instances are to be initiailized in advance, so each driver object can have a unique name. > Imagine this configuration: > > cpu -- PCI #1 -- PCI to PCI bridge -- PCI #2 -- PCI to ISA bridge -- sound card #1 on 0x100 > \- PCI to PCI bridge -- PCI #3 -- PCI to ISA bridge -- sound card #2 on 0x100 > > ...would you say that's supported?

Well, I don't think this can be problematic on ISA soundcards with platform_device. Anyway, I'll try to implement platform_device at first as a test... Thanks! Takashi
