Two things over here
- First interface between user application and smartcard controller
driver. There is already an open source f/w in user space called "pcsc"
exists for this.
- Second communication between smartcard controller and smartcard phy. I
have introduce lite interface called sc_phy which covers generic stuff
between controller and phy.
