Subject: [ 04/33] USB: ftdi_sio: add TIAO USB Multi-Protocol Adapter (TUMPA) support

3.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Antonio Ospite <ospite@...denti.unina.it>

commit 54575b05af36959dfb6a49a3e9ca0c2b456b7126 upstream.

TIAO/DIYGADGET USB Multi-Protocol Adapter (TUMPA) is an FTDI FT2232H
based device which provides an easily accessible JTAG, SPI, I2C, serial
breakout.

http://www.tiaowiki.com/w/TIAO_USB_Multi_Protocol_Adapter_User%27s_Manual

FTDI FT2232H provides two serial channels (A and B), but on the TUMPA
channel A is dedicated to JTAG/SPI while channel B can be used for
UART/RS-232: use the ftdi_jtag_quirk to expose only channel B as
a usb-serial interface to userspace.
