Subject[PATCH v3 0/2] add ISO7816 support
Date
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

tty/serial_core: add ISO7816 infrastructure
tty/serial: atmel: add ISO7816 support
