commit 6cf87e5edd9944e1d3b6efd966ea401effc304ee upstream.
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.

The use of SPD flags to set the line speed has been deprecated since

Also remove the verbose and outdated comment on how to set baud rates.

Specifically, the device latency timer would not be updated until next

If a BM type chip has iSerialNumber set to 0 in its EEPROM, an incorrect

look like an AM type chip. Attempt to correct this in
ftdi_determine_type() by attempting to read the latency timer for an AM

is a BM type chip.
Currently, read_latency_timer() bails out without reading the latency
timer for an AM type chip, so factor out the guts of
read_latency_timer() into a new function _read_latency_timer() that
attempts to read the latency timer regardless of chip type, and returns

FTDI devices use a receive latency timer to periodically empty the
receive buffer and report modem and line status (also when the buffer is
empty).
When a break or error condition is detected the corresponding status
flags will be set on a packet with nonzero data payload and the flags
are not updated until the break is over or further characters are
received.
In order to avoid over-reporting break and error conditions, these flags
must therefore only be processed for packets with payload.
This specifically fixes the case where after an overrun, the error
condition is continuously reported and NULL-characters inserted until
further data is received.

Since commit 557aaa7ffab6 ("ft232: support the ASYNC_LOW_LATENCY
flag") the FTDI driver has been using a receive latency-timer value of
1 ms instead of the device default of 16 ms.
The latency timer is used to periodically empty a non-full receive
buffer, but a status header is always sent when the timer expires
including when the buffer is empty. This means that a two-byte bulk
message is received every millisecond also for an otherwise idle port as
long as it is open.
Let's restore the pre-2009 behaviour which reduces the rate of the
status messages to 1/16th (e.g. interrupt frequency drops from 1 kHz to
62.5 Hz) by not setting ASYNC_LOW_LATENCY by default.
Anyone willing to pay the price for the minimum-latency behaviour should
set the flag explicitly instead using the TIOCSSERIAL ioctl or a tool
such as setserial (e.g. setserial /dev/ttyUSB0 low_latency).
Note that since commit 0cbd81a9f6ba ("USB: ftdi_sio: remove
tty->low_latency") the ASYNC_LOW_LATENCY flag has no other effects but
to set a minimal latency timer.

This adds support to ftdi_sio for the Infineon TriBoard TC2X7
engineering board for first-generation Aurix SoCs with Tricore CPUs.
Mere addition of the device IDs does the job.

BCM20706V2_EVAL is a WICED dev board designed with FT2232H USB 2.0
UART/FIFO IC.
To support BCM920706V2_EVAL dev board for WICED development on Linux.
Add the VID(0a5c) and PID(6422) to ftdi_sio driver to allow loading
ftdi_sio for this board.

The ftdi_sio_quirk structures are never modified, so declare them as
const.

A Fedora user reports that the ftdi_sio driver works properly for the
ICP DAS I-7561U device. Further, the user manual for these devices
instructs users to load the driver and add the ids using the sysfs
interface.
Add support for these in the driver directly so that the devices work
out of the box instead of needing manual configuration.

Harald Linden reports that the ftdi_sio driver works properly for the
Yaesu SCU-18 cable if the device ids are added to the driver. So let's
add them.
