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:
- 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
