The patches contained in this directory need to be applied to the Linux kernel
ftdi_sio driver, specifically to ftdi_sio.c and ftdi_sio_ids.h source files.
This patch adds support for Falconia/FreeCalypso custom USB IDs with
appropriate quirks applied:

* FreeCalypso buffered and unbuffered JTAG+UART adapters are recognized and
  treated as such, creating a ttyUSBx device for Channel B, but not for
  Channel A.

* DUART28C USB ID is treated with the appropriate quirk, suppressing automatic
  DTR & RTS assertion on ttyUSBx open for Channel B.

The present patches have been made against Linux kernel version 4.4.14;
application to other kernel versions may require minor porting.
