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. >> include/linux/ti-usim.h | 98 + >> 6 files changed, 2859 insertions(+), 0 deletions(-) >> create mode 100644 Documentation/devicetree/bindings/ti-usim/ti-usim.txt >> create mode 100644 drivers/char/ti-usim-hw.h >> create mode 100644 drivers/char/ti-usim.c >> create mode 100644 include/linux/ti-usim.h >> > > cheers, > -roger > -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
