Driver for a SmartCard interface on a SoC

[Juergen Beisert]

Hi,

most SmartCard readers are external devices, connected via USB or serial 
lines. 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?

Regards,
Juergen
