Hmm, if it is a PCI device, then surely you should know the PCI ID you are binding too? > So my idea is to create a "mapping" driver.

That might be a way, however there's not really a good way to add interrupts dynamically. -- Ben ([email protected], http://www.fluff.org/) 'a smiley only costs 4 bytes' -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
