So, they do not need special in-kernel drivers. My SmartCard interface is part of a SoC (i.MX25 CPU). So, I need an in-kernel driver. Where would be the best place in the kernel tree, to add a driver for this kind of device? Maybe "drivers/char"? To exchange data with the plugged in SmartCard, only a couple of IOCTLs are required (detecting if a card is plugged in, socket power on/off, send reset to the card, configuring the communication parameters). Data exchange with the SmartCard can be done with simple read/write. Any idea?
