* The 8U232AM has the same API as the sio except for:
* - it can support MUCH higher baudrates; up to:
* o 921600 for RS232 and 2000000 for RS422/485 at 48MHz
* o 230400 at 12MHz
* so .. 8U232AM's baudrate setting codes are different
* - it has a two byte status code.
* - it returns characters every 16ms (the FTDI does it every 40ms)
*
* the bcdDevice value is used to differentiate FT232BM and FT245BM from
* the earlier FT8U232AM and FT8U232BM. For now, include all known VID/PID
* combinations in both tables.
* FIXME: perhaps bcdDevice can also identify 12MHz FT8U232AM devices,
* but I don't know if those ever went into mass production. [Ian Abbott]

USB: ftdi_sio: add support for FT-X series devices Add PID 0x6015, corresponding to the new series of FT-X chips (FT220XD, FT201X, FT220X, FT221X, FT230X, FT231X, FT240X). They all appear as serial devices, and seem indistinguishable except for the default product string stored in their EEPROM. The baudrate generation matches FT232RL devices. Tested with a FT201X and FT230X at various baudrates (100 - 3000000).

USB: serial: ftdi_sio: add support for FreeCalypso JTAG+UART adapters There exist many FT2232-based JTAG+UART adapter designs in which FT2232 Channel A is used for JTAG and Channel B is used for UART. The best way to handle them in Linux is to have the ftdi_sio driver create a ttyUSB device only for Channel B and not for Channel A: a ttyUSB device for Channel A would be bogus and will disappear as soon as the user runs OpenOCD or other applications that access Channel A for JTAG from userspace, causing undesirable noise for users. The ftdi_sio driver already has a dedicated quirk for such JTAG+UART FT2232 adapters, and it requires assigning custom USB IDs to such adapters and adding these IDs to the driver with the ftdi_jtag_quirk applied. Boutique hardware manufacturer Falconia Partners LLC has created a couple of JTAG+UART adapter designs (one buffered, one unbuffered) as part of FreeCalypso project, and this hardware is specifically made to be used with Linux hosts, with the intent that Channel A will be accessed only from userspace via appropriate applications, and that Channel B will be supported by the ftdi_sio kernel driver, presenting a standard ttyUSB device to userspace. Toward this end the hardware manufacturer will be programming FT2232 EEPROMs with custom USB IDs, specifically with the intent that these IDs will be recognized by the ftdi_sio driver with the ftdi_jtag_quirk applied.

USB: ftdi_sio: add support for FT-X series devices Add PID 0x6015, corresponding to the new series of FT-X chips (FT220XD, FT201X, FT220X, FT221X, FT230X, FT231X, FT240X). They all appear as serial devices, and seem indistinguishable except for the default product string stored in their EEPROM. The baudrate generation matches FT232RL devices. Tested with a FT201X and FT230X at various baudrates (100 - 3000000).

[PATCH] USB: ftdi_sio: avoid losing received data in tty-ldisc ftdi_sio: Avoid losing bytes at tty-ldisc. This patch was originally developed by Daniel Smertnig. I (Ian Abbott) made a few changes. It has been tested by both Daniel and I, at least for raw, non-canonical receive data processing. Here is Daniel's original description of the patch: === During a project in which I was using a FTDI 232BM to transmit data at relative high speeds (625kBit/s), I noticed a problem where data was lost even if flow control was enabled: The FTDI-Driver receives 512 Bytes of data over USB at a time, which consists of 8 64-Byte packets. Subtracting the 2 bytes of status information included in each packet this gives 496 "real" data bytes per read. This data is passed (indirectly, via the flip buffers) to the tty line discipline which takes care of throttling when there the free buffer space reaches TTY_THRESHOLD_THROTTLE (128). Because the FTDI driver processes up to 496 bytes at a time, throttling won't happen in time and the line discipline will discard the remaining bytes. To avoid this the patch passes data in 62-byte blocks to the tty layer and checks the available space in the ldisc-buffers. If there isn't enough free space, processing the rest of the data is delayed using a workqueue. Note: The original problem should be easily reproducible with a userspace program which does slow & small reads. === Signed-off-by: Ian Abbott <abbotti@mev.co.uk> Signed-off-by: Daniel Smertnig <daniel.smertnig@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
