commit 6dbd46c849e071e6afc1e0cad489b0175bca9318 upstream.
Hello,
the following patch adds an entry for the PID of a Cressi Leonardo
diving computer interface to kernel 3.13.0.
It is detected as FT232RL.
Works with subsurface.

Adding two more IDs to the ftdi_sio usb serial driver.
It now connects Tagsys RFID readers.
There might be more IDs out there for other Tagsys models.

commit c1f15196ac3b541d084dc80a8fbd8a74c6a0bd44 upstream.
Genuine FTDI chips support only CS7/8. A previous fix in commit
8704211f65a2 ("USB: ftdi_sio: fixed handling of unsupported CSIZE
setting") enforced this limitation and reported it back to userspace.
However, certain types of smartcard readers depend on specific
driver behaviour that requests 0 data bits (not 5) to change into a
different operating mode if CS5 has been set.
This patch reenables this behaviour for all FTDI devices.
Tagged to be added to stable, because it affects a lot of users of
embedded systems which rely on these readers to work properly.

commit 8704211f65a2106ba01b6ac9727cdaf9ca11594c upstream.
FTDI UARTs support only 7 or 8 data bits. Until now the ftdi_sio driver would
only report this limitation for CS6 to dmesg and fail to reflect this fact to
tcgetattr.
This patch reverts the unsupported CSIZE setting and reports the fact with less
severance to dmesg for both CS5 and CS6.
To test the patch it's sufficient to call
stty -F /dev/ttyUSB0 cs5
which will succeed without the patch and report an error with the patch
applied.
As an additional fix this patch ensures that the control request will always
include a data bit size.

Clean up the DEVICE_ATTR usage in the USB serial drivers, making them
more obvious as to the permissions that the sysfs files should be.
Note: ftdi_sio.c still has a DEVICE_ATTR() used, that will have to wait

Remove the vendor and product module parameters which were added a long
time ago when we did not have the dynamic sysfs interface to add
new device ids (and which isn't limited to a single new vid/pid pair).
A vid/pid pair can be added dynamically using sysfs, for example:
echo 0403 1234 >/sys/bus/usb-serial/drivers/ftdi_sio/new_id
Also fix up the in-code comment that got the sysfs path wrong.

Use the new generic usb-serial wait_until_sent implementation to wait
for hardware buffers to drain.
This removes the need to check the hardware buffers in chars_in_buffer
and thus removes the overhead introduced by commit 6f602912 ("usb:
serial: ftdi_sio: Add missing chars_in_buffer function") without
breaking tty_wait_until_sent (used by, for example, tcdrain, tcsendbreak
and close).

UART FTDI chip. It is also possible to drive STM reference targets
populated with an on-board JTAG debugger based on the FT2232H chip with
the same STMicroelectronics tools.
For this reason, the ST Micro Connect Lite PIDs should be

Remove the port data refcounting and release the private data
explicitly at port remove.
The port data refcounting was used to make sure the port data was not
freed until the last tty reference was closed. Since moving over to tty
ports, the underlying assumptions are no longer valid as close is now
called as part of tty port shutdown, which can occur before the final
tty reference is dropped on device disconnect.
This means that the private port data refcounting is now completely
useless, as the last reference will always be dropped on port_remove.

Use the port wait queue and make sure to check the serial disconnected
flag before accessing private port data after waking up.
This is is needed as the private port data (including the wait queue
itself) can be gone when waking up after a disconnect.
When switching to tty ports, some lifetime assumptions were changed.
Specifically, close can now be called before the final tty reference is
dropped as part of hangup at device disconnect. Even with the ftdi
private-data refcounting this means that the port private data can be
freed while a process is sleeping on modem-status changes and thus
cannot be relied on to detect disconnects when woken up.

Make sure serial-driver dtr_rts is called with disc_mutex held after
checking the disconnected flag.
Due to a bug in the tty layer, dtr_rts may get called after a device has
been disconnected and the tty-device unregistered. Some drivers have had
individual checks for disconnect to make sure the disconnected interface
was not accessed, but this should really be handled in usb-serial core
(at least until the long-standing tty-bug has been fixed).
Note that the problem has been made more acute with commit 0998d0631001
("device-core: Ensure drvdata = NULL when no driver is bound") as the
port data is now also NULL when dtr_rts is called resulting in further
oopses.

Now, we start converting tty buffer functions to actually use
tty_port. This will allow us to get rid of the need of tty in many
call sites. Only tty_port will needed and hence no more
tty_port_tty_get in those paths.
Now, the one where most of tty_port_tty_get gets removed:
tty_flip_buffer_push.
IOW we also closed all the races in drivers not using tty_port_tty_get
at all yet.
Also we move tty_flip_buffer_push declaration from include/linux/tty.h
to include/linux/tty_flip.h to all others while we are changing it
anyway.

The driver does not wait until the hardware buffer (for data from the PC to the
UART line) is drained when tcdrain or close is called in an application.
Solution: Implement a chars_in_buffer function that checks both the software
and hardware buffer. If the TEMT (TX empty) bit of the line status register
indicates the hw buffer is not empty, let the function return at least 1. This
has been verified to work correctly with an FT232RL. The check on the hw buffer
can not be done for the original SIO device.

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.
