This is a patch to get the ELV FHZ1000 Home Automation control device to
work with Linux. The patch adds a new device ID to the ftdi_sio driver.
It is for kernel version 2.6.13.4.

This fixes up a lot of problems in sysfs with some of the usb serial
drivers, they had incorrect driver names. Also saves a tiny ammount
of memory.

I'm tired of trying to explain why a "device_type" is really a driver.
This better describes exactly what this structure is.

This patch enables direct kernel support for the Artemis
and ATIK astronomical based USB CCD cameras.
Since all communications with this camera are done via an
FTDI 245BM chip, it was only needed to specify the
ProductID and VendorID of all three devices.
In what tests are concerned, data was transfered from and
to the FTDI at the chips Top speed (360KB/s).

I'm using a 2 port USB RS232 dongle to connect to a serial-IR cradle for
a bar code reader). Detecting the baudrate of the serial-IR involves
keeping DTR low while changing baudrate.
This works using normal 16550A serial ports as well as the FTDI driver
version 1.4.0 (Linux 2.6.8) but stopped working with the change to
"ensure RTS and DTR are raised when changing baudrate" introduced in
version 1.4.1 (Linux 2.6.9).
The attached patch fixes this, so RTS and DTR is only raised when
changing baudrate iff the previous baudrate was B0.

This patch for the ftdi_sio driver adds a bunch of new devices and fixes
an incorrect PID:
o Fix PID for ELV UO100 (the PID was in fact for ELV UR100).
o Add PID ELV UR100 (see above) and ELV ALC 8500 Expert.
o Add a whole bunch of other PIDs for ELV USB devices, commented out for
now as they may be used by other drivers eventually. (Christian Abt
of ELV.de submitted a full list of devices including an indication of
which set of drivers are used by default in the MS Windows world. We
decided to comment out the devices that use FTDI's D2XX Windows
drivers by default.)
o Add PIDs for eight devices from Xsens Technologies BV (submitted in a
patch against 2.6.12.2 by Patrick Riphagen).
o Add PID for Falcom Samba GPRS modem (submitted by Sebastian Schubert).

ftdi_sio: Update RTS and DTR simultaneously, using a single control URB
instead of separate control URBs for RTS and DTR. Reinhard Bergmann
observed time differences of up to 680 ms with his application on a
2.4.22 kernel when RTS and DTR were updated using separate control
URBs, which is unacceptable.

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.

* Replaced FTDI_8U232AM_ALT_ALT_PID with 3 PIDs for devices from
4n-galaxy.de.
* Removed redundant FTDI_RM_VID and renamed FTDI_RMCANVIEW_PID to
FTDI_RM_CANVIEW_PID.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
