[PATCH v3 0/2] add ISO7816 support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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
