Maybe passing the GPIO number an requiring the driver to request the GPIO, set its direction and use it as IRQ line. the only problem would arise if we end up hooking the Card Detect pin to a real IRQ line, but then we can use a flag to differentiate. -- balbi -------------- next part -------------- A non-text attachment was scrubbed...
