Hmmm, AFAIU fsi is a bus, and on this bus you have some "client" device that happens to be an i2c master, and this is a driver for that "client". Is it totally inconceivable to have some other client device in the future that is implementing an i2c master differently, but still using the fsi bus? With that in mind, is it wise to pick the driver name from the bus that the device is connected to, and nothing else without further qualification? I don't see any "i2c-usb" driver, but I think there are a couple of i2c master drivers that communicate via usb. Cheers, Peter
