Hi, This patchset adds support for the ISO7816 standard. The USART devices in Microchip SoCs have an ISO7816 mode. It allows to let the USART managing the CLK and I/O signals of a smart card. Changes: - v3 - add IOCTLs to parisc arch. - rework atmel_config_iso7816 according to the comments by Richard - keep max iteration hard coded. Will see later if the user need to set this value. It may also concern the normal/inverse mode. - improve the checking of the value from the user space. - v2 - uart_get_iso7816_config: check there is an iso7816_config function - use IOCTL macros to generate the IOCTL number - check that reserved field is not used - remove debug logs - check that the iso7816_config is right before doing any action - change the error from nack and max iteration status to a debug message - remove patch 3 as it concerns both rs485 and iso7816 to think more about the need of adding a lock or not Nicolas Ferre (2): tty/serial_core: add ISO7816 infrastructure tty/serial: atmel: add ISO7816 support arch/alpha/include/uapi/asm/ioctls.h | 2 + arch/mips/include/uapi/asm/ioctls.h | 2 + arch/parisc/include/uapi/asm/ioctls.h | 2 + arch/powerpc/include/uapi/asm/ioctls.h | 2 + arch/sh/include/uapi/asm/ioctls.h | 2 + arch/sparc/include/uapi/asm/ioctls.h | 2 + arch/xtensa/include/uapi/asm/ioctls.h | 2 + drivers/tty/serial/atmel_serial.c | 211 ++++++++++++++++++++++++++++++--- drivers/tty/serial/atmel_serial.h | 6 +- drivers/tty/serial/serial_core.c | 60 ++++++++++ include/linux/serial_core.h | 3 + include/uapi/asm-generic/ioctls.h | 2 + include/uapi/linux/serial.h | 17 +++ 13 files changed, 297 insertions(+), 16 deletions(-) -- 2.12.2 -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
