 * See Documentation/usb/usb-serial.txt for more information on using this driver

 *

 * (12/10/2002) gkh

 *	Split the ports off into their own struct device, and added a

 *	usb-serial bus driver.

 *

 * (11/19/2002) gkh

 *	removed a few #ifdefs for the generic code and cleaned up the failure

 *	logic in initialization.

 *

 * (10/02/2002) gkh

 *	moved the console code to console.c and out of this file.

 *

 * (06/05/2002) gkh

 *	moved location of startup() call in serial_probe() until after all

 *	of the port information and endpoints are initialized.  This makes

 *	things easier for some drivers.

 *

 * (04/10/2002) gkh

 *	added serial_read_proc function which creates a

 *	/proc/tty/driver/usb-serial file.

 *

 * (03/27/2002) gkh

 *	Got USB serial console code working properly and merged into the main

 *	version of the tree.  Thanks to Randy Dunlap for the initial version

 *	of this code, and for pushing me to finish it up.

 *	The USB serial console works with any usb serial driver device.

 *

 * (03/21/2002) gkh

 *	Moved all manipulation of port->open_count into the core.  Now the

 *	individual driver's open and close functions are called only when the

 *	first open() and last close() is called.  Making the drivers a bit

 *	smaller and simpler.

 *	Fixed a bug if a driver didn't have the owner field set.

 *

 * (02/26/2002) gkh

 *	Moved all locking into the main serial_* functions, instead of having 

 *	the individual drivers have to grab the port semaphore.  This should

 *	reduce races.

 *	Reworked the MOD_INC logic a bit to always increment and decrement, even

 *	if the generic driver is being used.

 *

 * (10/10/2001) gkh

 *	usb_serial_disconnect() now sets the serial->dev pointer is to NULL to

 *	help prevent child drivers from accessing the device since it is now

 *	gone.

 *

 * (09/13/2001) gkh

 *	Moved generic driver initialize after we have registered with the USB

 *	core.  Thanks to Randy Dunlap for pointing this problem out.

 *

 * (07/03/2001) gkh

 *	Fixed module paramater size.  Thanks to John Brockmeyer for the pointer.

 *	Fixed vendor and product getting defined through the MODULE_PARM macro

 *	if the Generic driver wasn't compiled in.

 *	Fixed problem with generic_shutdown() not being called for drivers that

 *	don't have a shutdown() function.

 *

 * (06/06/2001) gkh

 *	added evil hack that is needed for the prolific pl2303 device due to the

 *	crazy way its endpoints are set up.

 *

 * (05/30/2001) gkh

 *	switched from using spinlock to a semaphore, which fixes lots of problems.

 *

 * (04/08/2001) gb

 *	Identify version on module load.

 *

 * 2001_02_05 gkh

 *	Fixed buffer overflows bug with the generic serial driver.  Thanks to

 *	Todd Squires <squirest@ct0.com> for fixing this.

 *

 * (01/10/2001) gkh

 *	Fixed bug where the generic serial adaptor grabbed _any_ device that was

 *	offered to it.

 *

 * (12/12/2000) gkh

 *	Removed MOD_INC and MOD_DEC from poll and disconnect functions, and

 *	moved them to the serial_open and serial_close functions.

 *	Also fixed bug with there not being a MOD_DEC for the generic driver

 *	(thanks to Gary Brubaker for finding this.)

 *

 * (11/29/2000) gkh

 *	Small NULL pointer initialization cleanup which saves a bit of disk image

 *

 * (11/01/2000) Adam J. Richter

 *	instead of using idVendor/idProduct pairs, usb serial drivers

 *	now identify their hardware interest with usb_device_id tables,

 *	which they usually have anyhow for use with MODULE_DEVICE_TABLE.

 *

 * (10/05/2000) gkh

 *	Fixed bug with urb->dev not being set properly, now that the usb

 *	core needs it.

 * 

 * (09/11/2000) gkh

 *	Removed DEBUG #ifdefs with call to usb_serial_debug_data

 *

 * (08/28/2000) gkh

 *	Added port_lock to port structure.

 *	Added locks for SMP safeness to generic driver

 *	Fixed the ability to open a generic device's port more than once.

 *

 * (07/23/2000) gkh

 *	Added bulk_out_endpointAddress to port structure.

 *

 * (07/19/2000) gkh, pberger, and borchers

 *	Modifications to allow usb-serial drivers to be modules.

 *

 * (07/03/2000) gkh

 *	Added more debugging to serial_ioctl call

 * 

 * (06/25/2000) gkh

 *	Changed generic_write_bulk_callback to not call wake_up_interruptible

 *	directly, but to have port_softint do it at a safer time.

 *

 * (06/23/2000) gkh

 *	Cleaned up debugging statements in a quest to find UHCI timeout bug.

 *

 * (05/22/2000) gkh

 *	Changed the makefile, enabling the big CONFIG_USB_SERIAL_SOMTHING to be 

 *	removed from the individual device source files.

 *

 * (05/03/2000) gkh

 *	Added the Digi Acceleport driver from Al Borchers and Peter Berger.

 * 

 * (05/02/2000) gkh

 *	Changed devfs and tty register code to work properly now. This was based on

 *	the ACM driver changes by Vojtech Pavlik.

 *

 * (04/27/2000) Ryan VanderBijl

 * 	Put calls to *_paranoia_checks into one function.

 * 

 * (04/23/2000) gkh

 *	Fixed bug that Randy Dunlap found for Generic devices with no bulk out ports.

 *	Moved when the startup code printed out the devices that are supported.

 *

 * (04/19/2000) gkh

 *	Added driver for ZyXEL omni.net lcd plus ISDN TA

 *	Made startup info message specify which drivers were compiled in.

 *

 * (04/03/2000) gkh

 *	Changed the probe process to remove the module unload races.

 *	Changed where the tty layer gets initialized to have devfs work nicer.

 *	Added initial devfs support.

 *

 * (03/26/2000) gkh

 *	Split driver up into device specific pieces.

 * 

 * (03/19/2000) gkh

 *	Fixed oops that could happen when device was removed while a program

 *	was talking to the device.

 *	Removed the static urbs and now all urbs are created and destroyed

 *	dynamically.

 *	Reworked the internal interface. Now everything is based on the 

 *	usb_serial_port structure instead of the larger usb_serial structure.

 *	This fixes the bug that a multiport device could not have more than

 *	one port open at one time.

 *

 * (03/17/2000) gkh

 *	Added config option for debugging messages.

 *	Added patch for keyspan pda from Brian Warner.

 *

 * (03/06/2000) gkh

 *	Added the keyspan pda code from Brian Warner <warner@lothar.com>

 *	Moved a bunch of the port specific stuff into its own structure. This

 *	is in anticipation of the true multiport devices (there's a bug if you

 *	try to access more than one port of any multiport device right now)

 *

 * (02/21/2000) gkh

 *	Made it so that any serial devices only have to specify which functions

 *	they want to overload from the generic function calls (great, 

 *	inheritance in C, in a driver, just what I wanted...)

 *	Added support for set_termios and ioctl function calls. No drivers take

 *	advantage of this yet.

 *	Removed the #ifdef MODULE, now there is no module specific code.

 *	Cleaned up a few comments in usb-serial.h that were wrong (thanks again

 *	to Miles Lott).

 *	Small fix to get_free_serial.

 *

 * (02/14/2000) gkh

 *	Removed the Belkin and Peracom functionality from the driver due to

 *	the lack of support from the vendor, and me not wanting people to 

 *	accidenatly buy the device, expecting it to work with Linux.

 *	Added read_bulk_callback and write_bulk_callback to the type structure

 *	for the needs of the FTDI and WhiteHEAT driver.

 *	Changed all reverences to FTDI to FTDI_SIO at the request of Bill

 *	Ryder.

 *	Changed the output urb size back to the max endpoint size to make

 *	the ftdi_sio driver have it easier, and due to the fact that it didn't

 *	really increase the speed any.

 *

 * (02/11/2000) gkh

 *	Added VISOR_FUNCTION_CONSOLE to the visor startup function. This was a

 *	patch from Miles Lott (milos@insync.net).

 *	Fixed bug with not restoring the minor range that a device grabs, if

 *	the startup function fails (thanks Miles for finding this).

 *

 * (02/05/2000) gkh

 *	Added initial framework for the Keyspan PDA serial converter so that

 *	Brian Warner has a place to put his code.

 *	Made the ezusb specific functions generic enough that different

 *	devices can use them (whiteheat and keyspan_pda both need them).

 *	Split out a whole bunch of structure and other stuff to a separate

 *	usb-serial.h file.

 *	Made the Visor connection messages a little more understandable, now

 *	that Miles Lott (milos@insync.net) has gotten the Generic channel to

 *	work. Also made them always show up in the log file.

 * 

 * (01/25/2000) gkh

 *	Added initial framework for FTDI serial converter so that Bill Ryder

 *	has a place to put his code.

 *	Added the vendor specific info from Handspring. Now we can print out

 *	informational debug messages as well as understand what is happening.

 *

 * (01/23/2000) gkh

 *	Fixed problem of crash when trying to open a port that didn't have a

 *	device assigned to it. Made the minor node finding a little smarter,

 *	now it looks to find a continuous space for the new device.

 *

 * (01/21/2000) gkh

 *	Fixed bug in visor_startup with patch from Miles Lott (milos@insync.net)

 *	Fixed get_serial_by_minor which was all messed up for multi port 

 *	devices. Fixed multi port problem for generic devices. Now the number

 *	of ports is determined by the number of bulk out endpoints for the

 *	generic device.

 *

 * (01/19/2000) gkh

 *	Removed lots of cruft that was around from the old (pre urb) driver 

 *	interface.

 *	Made the serial_table dynamic. This should save lots of memory when

 *	the number of minor nodes goes up to 256.

 *	Added initial support for devices that have more than one port. 

 *	Added more debugging comments for the Visor, and added a needed 

 *	set_configuration call.

 *

 * (01/17/2000) gkh

 *	Fixed the WhiteHEAT firmware (my processing tool had a bug)

 *	and added new debug loader firmware for it.

 *	Removed the put_char function as it isn't really needed.

 *	Added visor startup commands as found by the Win98 dump.

 * 

 * (01/13/2000) gkh

 *	Fixed the vendor id for the generic driver to the one I meant it to be.

 *

 * (01/12/2000) gkh

 *	Forget the version numbering...that's pretty useless...

 *	Made the driver able to be compiled so that the user can select which

 *	converter they want to use. This allows people who only want the Visor

 *	support to not pay the memory size price of the WhiteHEAT.

 *	Fixed bug where the generic driver (idVendor=0000 and idProduct=0000)

 *	grabbed the root hub. Not good.

 * 

 * version 0.4.0 (01/10/2000) gkh

 *	Added whiteheat.h containing the firmware for the ConnectTech WhiteHEAT

 *	device. Added startup function to allow firmware to be downloaded to

 *	a device if it needs to be.

 *	Added firmware download logic to the WhiteHEAT device.

 *	Started to add #defines to split up the different drivers for potential

 *	configuration option.

 *	

 * version 0.3.1 (12/30/99) gkh

 *      Fixed problems with urb for bulk out.

 *      Added initial support for multiple sets of endpoints. This enables

 *      the Handspring Visor to be attached successfully. Only the first

 *      bulk in / bulk out endpoint pair is being used right now.

 *

 * version 0.3.0 (12/27/99) gkh

 *	Added initial support for the Handspring Visor based on a patch from

 *	Miles Lott (milos@sneety.insync.net)

 *	Cleaned up the code a bunch and converted over to using urbs only.

 *

 * version 0.2.3 (12/21/99) gkh

 *	Added initial support for the Connect Tech WhiteHEAT converter.

 *	Incremented the number of ports in expectation of getting the

 *	WhiteHEAT to work properly (4 ports per connection).

 *	Added notification on insertion and removal of what port the

 *	device is/was connected to (and what kind of device it was).

 *

 * version 0.2.2 (12/16/99) gkh

 *	Changed major number to the new allocated number. We're legal now!

 *

 * version 0.2.1 (12/14/99) gkh

 *	Fixed bug that happens when device node is opened when there isn't a

 *	device attached to it. Thanks to marek@webdesign.no for noticing this.

 *

 * version 0.2.0 (11/10/99) gkh

 *	Split up internals to make it easier to add different types of serial 

 *	converters to the code.

 *	Added a "generic" driver that gets it's vendor and product id

 *	from when the module is loaded. Thanks to David E. Nelson (dnelson@jump.net)

 *	for the idea and sample code (from the usb scanner driver.)

 *	Cleared up any licensing questions by releasing it under the GNU GPL.

 *

 * version 0.1.2 (10/25/99) gkh

 * 	Fixed bug in detecting device.

 *

 * version 0.1.1 (10/05/99) gkh

 * 	Changed the major number to not conflict with anything else.

 *

 * version 0.1 (09/28/99) gkh

 * 	Can recognize the two different devices and start up a read from

 *	device when asked to. Writes also work. No control signals yet, this
