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: - v4 - use the IP version number instead of the compatible string to set min and max values for fidi. - remove a useless macro for fidi. - 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.
