Subject: [PATCH] USB: ftdi_sio: add TIAO USB Multi-Protocol Adapter (TUMPA) support
Date: Sun, 23 Sep 2012 09:57:25 +0200 [thread overview]
Message-ID: <1348387045-11525-1-git-send-email-ospite@studenti.unina.it> (raw)
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.
