Documentation/serial: Delete obsolete driver documentation

These serial drivers were removed in kernel v3.1, so we can drop their
documentation files and references to their magic numbers and
parameters.

There are still references to these old drivers in
Documentation/devices.txt but I'm afraid they can't be removed.

-NOTE:  This driver is obsolete.  Digi provides a 2.6 driver (dgdm) at
-http://www.digi.com for PCI cards.  They no longer maintain this driver,
-and have no 2.6 driver for ISA cards.
-
-This driver requires a number of user-space tools.  They can be acquired from
-http://www.digi.com, but only works with 2.4 kernels.
-
-
-The Digi Intl. epca driver. 
-----------------------------
-The Digi Intl. epca driver for Linux supports the following boards:
-
-Digi PC/Xem, PC/Xr, PC/Xe, PC/Xi, PC/Xeve 
-Digi EISA/Xem, PCI/Xem, PCI/Xr 
-
-Limitations:
-------------
-Currently the driver only autoprobes for supported PCI boards. 
-
-The Linux MAKEDEV command does not support generating the Digiboard
-Devices.  Users executing digiConfig to setup EISA and PC series cards
-will have their device nodes automatically constructed (cud?? for ~CLOCAL,
-and ttyD?? for CLOCAL).  Users wishing to boot their board from the LILO
-prompt, or those users booting PCI cards may use buildDIGI to construct 
-the necessary nodes. 
-
-Notes:
-------
-This driver may be configured via LILO.  For users who have already configured
-their driver using digiConfig, configuring from LILO will override previous 
-settings.  Multiple boards may be configured by issuing multiple LILO command 
-lines.  For examples see the bottom of this document.
-
-Device names start at 0 and continue up.  Beware of this as previous Digi 
-drivers started device names with 1.
-
-PCI boards are auto-detected and configured by the driver.  PCI boards will
-be allocated device numbers (internally) beginning with the lowest PCI slot
-first.  In other words a PCI card in slot 3 will always have higher device
-nodes than a PCI card in slot 1. 
-
-LILO config examples:
----------------------
-Using LILO's APPEND command, a string of comma separated identifiers or 
-integers can be used to configure supported boards.  The six values in order 
-are:
-
-   Enable/Disable this card or Override,
-   Type of card: PC/Xe (AccelePort) (0), PC/Xeve (1), PC/Xem or PC/Xr (2), 
-                 EISA/Xem (3), PC/64Xe (4), PC/Xi (5), 
-   Enable/Disable alternate pin arrangement,
-   Number of ports on this card,
-   I/O Port where card is configured (in HEX if using string identifiers),
-   Base of memory window (in HEX if using string identifiers), 
-
-NOTE : PCI boards are auto-detected and configured.  Do not attempt to 
-configure PCI boards with the LILO append command.  If you wish to override
-previous configuration data (As set by digiConfig), but you do not wish to
-configure any specific card (Example if there are PCI cards in the system) 
-the following override command will accomplish this:
--> append="digi=2"
-
-Samples:
-   append="digiepca=E,PC/Xe,D,16,200,D0000"
-                  or
-   append="digi=1,0,0,16,512,851968"
-
-Supporting Tools:
------------------
-Supporting tools include digiDload, digiConfig, buildPCI, and ditty.  See
-drivers/char/README.epca for more details.  Note,
-this driver REQUIRES that digiDload be executed prior to it being used. 
-Failure to do this will result in an ENODEV error.

-Complete documentation for this product may be found in the tool package.

-Misc. notes for RISCom/8 serial driver, in no particular order :)
-
-1) This driver can support up to 4 boards at time.
-   Use string "riscom8=0xXXX,0xXXX,0xXXX,0xXXX" at LILO prompt, for
-   setting I/O base addresses for boards. If you compile driver
-   as module use modprobe options "iobase=0xXXX iobase1=0xXXX iobase2=..."
-
-2) The driver partially supports famous 'setserial' program, you can use almost
-   any of its options, excluding port & irq settings.
-
-3) There are some misc. defines at the beginning of riscom8.c, please read the 
-   comments and try to change some of them in case of problems.
-
-4) I consider the current state of the driver as BETA.
-
-5) SDL Communications WWW page is http://www.sdlcomm.com.
-
-6) You can use the MAKEDEV program to create RISCom/8 /dev/ttyL* entries.
-
-7) Minor numbers for first board are 0-7, for second 8-15, etc.

-Intro
-=====
-
- 
-This file contains some random information, that I like to have online
-instead of in a manual that can get lost. Ever misplace your Linux
-kernel sources?  And the manual of one of the boards in your computer?
-
-
-Addresses and interrupts
-========================
-
-Address dip switch settings:
-The dip switch sets bits 2-9 of the IO address. 
-
-       9 8 7 6 5 4 3 2 
-     +-----------------+
-   0 | X   X X X X X X |
-     |                 |    =   IoBase = 0x100 
-   1 |   X             |
-     +-----------------+          ------ RS232 connectors ---->

-       edge connector
-         |    |    |
-         V    V    V
-
-Base address 0x100 caused a conflict in one of my computers once.  I
-haven't the foggiest why. My Specialix card is now at 0x180.  My
-other computer runs just fine with the Specialix card at 0x100....
-The card occupies 4 addresses, but actually only two are really used.
-
-The PCI version doesn't have any dip switches. The BIOS assigns
-an IO address. 
-
-The driver now still autoprobes at 0x100, 0x180, 0x250 and 0x260.  If
-that causes trouble for you, please report that. I'll remove
-autoprobing then.
-
-The driver will tell the card what IRQ to use, so you don't have to
-change any jumpers to change the IRQ. Just use a command line
-argument (irq=xx) to the insmod program to set the interrupt.
-
-The BIOS assigns the IRQ on the PCI version. You have no say in what
-IRQ to use in that case. 
-
-If your specialix cards are not at the default locations, you can use
-the kernel command line argument "specialix=io0,irq0,io1,irq1...".
-Here "io0" is the io address for the first card, and "irq0" is the
-irq line that the first card should use. And so on. 
-
-Examples. 
-
-You use the driver as a module and have three cards at 0x100, 0x250
-and 0x180. And some way or another you want them detected in that
-order. Moreover irq 12 is taken (e.g. by your PS/2 mouse).
-
-  insmod specialix.o iobase=0x100,0x250,0x180 irq=9,11,15
-
-The same three cards, but now in the kernel would require you to
-add 
-
-   specialix=0x100,9,0x250,11,0x180,15
-
-to the command line. This would become 
-
-   append="specialix=0x100,9,0x250,11,0x180,15" 
-
-in your /etc/lilo.conf file if you use lilo. 
-
-The Specialix driver is slightly odd: It allows you to have the second
-or third card detected without having a first card. This has
-advantages and disadvantages. A slot that isn't filled by an ISA card,
-might be filled if a PCI card is detected. Thus if you have an ISA
-card at 0x250 and a PCI card, you would get:
-
-sx0: specialix IO8+ Board at 0x100 not found.
-sx1: specialix IO8+ Board at 0x180 not found.
-sx2: specialix IO8+ board detected at 0x250, IRQ 12, CD1865 Rev. B.
-sx3: specialix IO8+ Board at 0x260 not found.
-sx0: specialix IO8+ board detected at 0xd800, IRQ 9, CD1865 Rev. B.
-
-This would happen if you don't give any probe hints to the driver. 
-If you would specify:
-
-   specialix=0x250,11
-
-you'd get the following messages:
-
-sx0: specialix IO8+ board detected at 0x250, IRQ 11, CD1865 Rev. B.
-sx1: specialix IO8+ board detected at 0xd800, IRQ 9, CD1865 Rev. B.
-
-ISA probing is aborted after the IO address you gave is exhausted, and
-the PCI card is now detected as the second card. The ISA card is now
-also forced to IRQ11....
-
-
-Baud rates
-==========
-
-The rev 1.2 and below boards use a CL-CD1864. These chips can only 
-do 64kbit. The rev 1.3 and newer boards use a CL-CD1865. These chips
-are officially capable of 115k2.
-
-The Specialix card uses a 25MHz crystal (in times two mode, which in
-fact is a divided by two mode). This is not enough to reach the rated
-115k2 on all ports at the same time. With this clock rate you can only
-do 37% of this rate. This means that at 115k2 on all ports you are
-going to lose characters (The chip cannot handle that many incoming
-bits at this clock rate.) (Yes, you read that correctly: there is a
-limit to the number of -=bits=- per second that the chip can handle.)
-
-If you near the "limit" you will first start to see a graceful
-degradation in that the chip cannot keep the transmitter busy at all
-times. However with a central clock this slow, you can also get it to
-miss incoming characters. The driver will print a warning message when
-you are outside the official specs. The messages usually show up in
-the file /var/log/messages .
-
-The specialix card cannot reliably do 115k2. If you use it, you have
-to do "extensive testing" (*) to verify if it actually works.
-
-When "mgetty" communicates with my modem at 115k2 it reports:
-got: +++[0d]ATQ0V1H0[0d][0d][8a]O[cb][0d][8a]
-                            ^^^^ ^^^^    ^^^^ 
-
-The three characters that have the "^^^" under them have suffered a
-bit error in the highest bit. In conclusion: I've tested it, and found
-that it simply DOESN'T work for me. I also suspect that this is also
-caused by the baud rate being just a little bit out of tune. 
-
-I upgraded the crystal to 66Mhz on one of my Specialix cards. Works
-great! Contact me for details. (Voids warranty, requires a steady hand
-and more such restrictions....)

- 
-Hardware handshaking issues.
-============================
-
-The driver can be told to operate in two different ways. The default
-behaviour is specialix.sx_rtscts = 0 where the pin behaves as DTR when
-hardware handshaking is off. It behaves as the RTS hardware
-handshaking signal when hardware handshaking is selected.
-
-When you use this, you have to use the appropriate cable. The
-cable will either be compatible with hardware handshaking or with
-software handshaking. So switching on the fly is not really an
-option.
-
-I actually prefer to use the "specialix.sx_rtscts=1" option.
-This makes the DTR/RTS pin always an RTS pin, and ioctls to
-change DTR are always ignored. I have a cable that is configured
-for this. 
-
-
-Ports and devices
-=================
-
-Port 0 is the one furthest from the card-edge connector.
-
-Devices:
-
-You should make the devices as follows:
-
-bash
-cd /dev
-for i in  0  1  2  3  4  5  6  7  8  9 10 11 12 13 14 15 \
-         16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31
-do
-  echo -n "$i "
-  mknod /dev/ttyW$i c 75 $i
-  mknod /dev/cuw$i c 76 $i
-done
-echo ""
-
-If your system doesn't come with these devices preinstalled, bug your
-linux-vendor about this. They have had ample time to get this
-implemented by now.
-
-You cannot have more than 4 boards in one computer. The card only
-supports 4 different interrupts. If you really want this, contact me
-about this and I'll give you a few tips (requires soldering iron)....
-
-If you have enough PCI slots, you can probably use more than 4 PCI
-versions of the card though.... 
-
-The PCI version of the card cannot adhere to the mechanical part of
-the PCI spec because the 8 serial connectors are simply too large. If
-it doesn't fit in your computer, bring back the card.
-
-
-------------------------------------------------------------------------
-
-
-  Fixed bugs and restrictions:
-       - During initialization, interrupts are blindly turned on.
-            Having a shadow variable would cause an extra memory
-            access on every IO instruction. 
-       - The interrupt (on the card) should be disabled when we
-         don't allocate the Linux end of the interrupt. This allows 
-         a different driver/card to use it while all ports are not in
-         use..... (a la standard serial port)
-       == An extra _off variant of the sx_in and sx_out macros are
-          now available. They don't set the interrupt enable bit.
-          These are used during initialization. Normal operation uses
-          the old variant which enables the interrupt line.
-       - RTS/DTR issue needs to be implemented according to 
-         specialix' spec.
-            I kind of like the "determinism" of the current 
-            implementation. Compile time flag?
-       == Ok. Compile time flag! Default is how Specialix likes it.
-       == Now a config time flag! Gets saved in your config file. Neat!
-       - Can you set the IO address from the lilo command line?
-            If you need this, bug me about it, I'll make it. 
-       == Hah! No bugging needed. Fixed! :-)
-       - Cirrus logic hasn't gotten back to me yet why the CD1865 can
-            and the CD1864 can't do 115k2. I suspect that this is
-            because the CD1864 is not rated for 33MHz operation.
-            Therefore the CD1864 versions of the card can't do 115k2 on 
-            all ports just like the CD1865 versions. The driver does
-            not block 115k2 on CD1864 cards. 
-        == I called the Cirrus Logic representative here in Holland.
-           The CD1864 databook is identical to the CD1865 databook, 
-           except for an extra warning at the end. Similar Bit errors
-           have been observed in testing at 115k2 on both an 1865 and
-           a 1864 chip. I see no reason why I would prohibit 115k2 on
-           1864 chips and not do it on 1865 chips. Actually there is
-           reason to prohibit it on BOTH chips. I print a warning.
-           If you use 115k2, you're on your own. 
-       - A spiky CD may send spurious HUPs. Also in CLOCAL???
-         -- A fix for this turned out to be counter productive. 
-            Different fix? Current behaviour is acceptable?
-         -- Maybe the current implementation is correct. If anybody
-            gets bitten by this, please report, and it will get fixed.
-
-         -- Testing revealed that when in CLOCAL, the problem doesn't
-            occur. As warned for in the CD1865 manual, the chip may
-            send modem intr's on a spike. We could filter those out,
-            but that would be a cludge anyway (You'd still risk getting
-            a spurious HUP when two spikes occur.).....
- 
-
-
-  Bugs & restrictions:
-       - This is a difficult card to autoprobe.
-            You have to WRITE to the address register to even 
-            read-probe a CD186x register. Disable autodetection?
-         -- Specialix: any suggestions?

-Introduction
-============
-
-This file contains some random information, that I like to have online
-instead of in a manual that can get lost. Ever misplace your Linux
-kernel sources?  And the manual of one of the boards in your computer?
-
-
-Theory of operation
-===================
-
-An important thing to know is that the driver itself doesn't have the
-firmware for the card. This means that you need the separate package
-"sx_firmware". For now you can get the source at
-
-	ftp://ftp.bitwizard.nl/specialix/sx_firmware_<version>.tgz
-
-The firmware load needs a "misc" device, so you'll need to enable the
-"Support for user misc device modules" in your kernel configuration.
-The misc device needs to be called "/dev/specialix_sxctl". It needs
-misc major 10, and minor number 167 (assigned by HPA). The section
-on creating device files below also creates this device. 
-
-After loading the sx.o module into your kernel, the driver will report
-the number of cards detected, but because it doesn't have any
-firmware, it will not be able to determine the number of ports. Only
-when you then run "sx_firmware" will the firmware be downloaded and
-the rest of the driver initialized. At that time the sx_firmware
-program will report the number of ports installed.
-
-In contrast with many other multi port serial cards, some of the data
-structures are only allocated when the card knows the number of ports
-that are connected. This means we won't waste memory for 120 port
-descriptor structures when you only have 8 ports. If you experience
-problems due to this, please report them: I haven't seen any.
-
-
-Interrupts
-==========
-
-A multi port serial card, would generate a horrendous amount of
-interrupts if it would interrupt the CPU for every received
-character. Even more than 10 years ago, the trick not to use
-interrupts but to poll the serial cards was invented.
-
-The SX card allow us to do this two ways. First the card limits its
-own interrupt rate to a rate that won't overwhelm the CPU. Secondly,
-we could forget about the cards interrupt completely and use the
-internal timer for this purpose.
-
-Polling the card can take up to a few percent of your CPU. Using the
-interrupts would be better if you have most of the ports idle. Using
-timer-based polling is better if your card almost always has work to
-do. You save the separate interrupt in that case.
-
-In any case, it doesn't really matter all that much. 
-
-The most common problem with interrupts is that for ISA cards in a PCI
-system the BIOS has to be told to configure that interrupt as "legacy
-ISA". Otherwise the card can pull on the interrupt line all it wants
-but the CPU won't see this.
-
-If you can't get the interrupt to work, remember that polling mode is
-more efficient (provided you actually use the card intensively).
-
-
-Allowed Configurations
-======================
-
-Some configurations are disallowed. Even though at a glance they might
-seem to work, they are known to lockup the bus between the host card
-and the device concentrators. You should respect the drivers decision
-not to support certain configurations. It's there for a reason.
-
-Warning: Seriously technical stuff ahead. Executive summary: Don't use
-SX cards except configured at a 64k boundary. Skip the next paragraph.
-
-The SX cards can theoretically be placed at a 32k boundary. So for
-instance you can put an SX card at 0xc8000-0xd7fff. This is not a
-"recommended configuration". ISA cards have to tell the bus controller
-how they like their timing. Due to timing issues they have to do this
-based on which 64k window the address falls into. This means that the
-32k window below and above the SX card have to use exactly the same
-timing as the SX card. That reportedly works for other SX cards. But
-you're still left with two useless 32k windows that should not be used
-by anybody else.
-
-
-Configuring the driver
-======================
-
-PCI cards are always detected. The driver auto-probes for ISA cards at
-some sensible addresses. Please report if the auto-probe causes trouble
-in your system, or when a card isn't detected.
-
-I'm afraid I haven't implemented "kernel command line parameters" yet.
-This means that if the default doesn't work for you, you shouldn't use
-the compiled-into-the-kernel version of the driver. Use a module
-instead.  If you convince me that you need this, I'll make it for
-you. Deal?
-
-I'm afraid that the module parameters are a bit clumsy. If you have a
-better idea, please tell me.
-
-You can specify several parameters:
-
-	sx_poll: number of jiffies between timer-based polls.
-
-		Set this to "0" to disable timer based polls. 
-                Initialization of cards without a working interrupt
-                will fail.
-
-		Set this to "1" if you want a polling driver. 
-		(on Intel: 100 polls per second). If you don't use
-                fast baud rates, you might consider a value like "5". 
-                (If you don't know how to do the math, use 1).
-
-	sx_slowpoll: Number of jiffies between timer-based polls. 
- 		Set this to "100" to poll once a second. 
-		This should get the card out of a stall if the driver
-                ever misses an interrupt. I've never seen this happen,
-                and if it does, that's a bug. Tell me. 
-
-	sx_maxints: Number of interrupts to request from the card. 
-		The card normally limits interrupts to about 100 per
-		second to offload the host CPU. You can increase this
-		number to reduce latency on the card a little.
-		Note that if you give a very high number you can overload
-		your CPU as well as the CPU on the host card. This setting 
-		is inaccurate and not recommended for SI cards (But it 
-		works). 
-
-	sx_irqmask: The mask of allowable IRQs to use. I suggest you set 
-		this to 0 (disable IRQs all together) and use polling if 
-		the assignment of IRQs becomes problematic. This is defined
-		as the sum of (1 << irq) 's that you want to allow. So 
-		sx_irqmask of 8 (1 << 3) specifies that only irq 3 may
-		be used by the SX driver. If you want to specify to the 
-		driver: "Either irq 11 or 12 is ok for you to use", then
-		specify (1 << 11) | (1 << 12) = 0x1800 . 
-
-	sx_debug: You can enable different sorts of debug traces with this. 
-		At "-1" all debugging traces are active. You'll get several
-		times more debugging output than you'll get characters 
-		transmitted. 
-
-
-Baud rates
-==========
-
-Theoretically new SXDCs should be capable of more than 460k
-baud. However the line drivers usually give up before that.  Also the
-CPU on the card may not be able to handle 8 channels going at full
-blast at that speed. Moreover, the buffers are not large enough to
-allow operation with 100 interrupts per second. You'll have to realize
-that the card has a 256 byte buffer, so you'll have to increase the
-number of interrupts per second if you have more than 256*100 bytes
-per second to transmit.  If you do any performance testing in this
-area, I'd be glad to hear from you...
-
-(Psst Linux users..... I think the Linux driver is more efficient than
-the driver for other OSes. If you can and want to benchmark them
-against each other, be my guest, and report your findings...... :-)
-
-
-Ports and devices
-=================
-
-Port 0 is the top connector on the module closest to the host
-card. Oh, the ports on the SXDCs and TAs are labelled from 1 to 8
-instead of from 0 to 7, as they are numbered by linux. I'm stubborn in
-this: I know for sure that I wouldn't be able to calculate which port
-is which anymore if I would change that....
-
-
-Devices:
-
-You should make the device files as follows:
-
-#!/bin/sh
-# (I recommend that you cut-and-paste this into a file and run that)
-cd /dev
-t=0
-mknod specialix_sxctl c 10 167
-while [ $t -lt 64 ]
-  do 
-  echo -n "$t "
-  mknod ttyX$t c 32 $t
-  mknod cux$t  c 33 $t
-  t=`expr $t + 1`
-done
-echo ""
-rm /etc/psdevtab
-ps > /dev/null
-
-
-This creates 64 devices. If you have more, increase the constant on
-the line with "while". The devices start at 0, as is customary on
-Linux. Specialix seems to like starting the numbering at 1. 
-
-If your system doesn't come with these devices pre-installed, bug your
-linux-vendor about this. They should have these devices
-"pre-installed" before the new millennium. The "ps" stuff at the end
-is to "tell" ps that the new devices exist.
-
-Officially the maximum number of cards per computer is 4. This driver
-however supports as many cards in one machine as you want. You'll run
-out of interrupts after a few, but you can switch to polled operation
-then. At about 256 ports (More than 8 cards), we run out of minor
-device numbers. Sorry. I suggest you buy a second computer.... (Or
-switch to RIO).

-
-  Fixed bugs and restrictions:
-	- Hangup processing.  
-	  -- Done.
-
-	- the write path in generic_serial (lockup / oops). 
-	  -- Done (Ugly: not the way I want it. Copied from serial.c).
-
-        - write buffer isn't flushed at close.
-	  -- Done. I still seem to lose a few chars at close. 
-	     Sorry. I think that this is a firmware issue. (-> Specialix)
-
-	- drain hardware before  changing termios
-	- Change debug on the fly. 
-	- ISA free irq -1. (no firmware loaded).
-	- adding c8000 as a probe address. Added warning. 
-	- Add a RAMtest for the RAM on the card.c
-        - Crash when opening a port "way" of the number of allowed ports. 
-          (for example opening port 60 when there are only 24 ports attached)
-	- Sometimes the use-count strays a bit. After a few hours of
-          testing the use count is sometimes "3". If you are not like
-          me and can remember what you did to get it that way, I'd
-          appreciate an Email. Possibly fixed. Tell me if anyone still
-          sees this.
-	- TAs don't work right if you don't connect all the modem control
-	  signals. SXDCs do. T225 firmware problem -> Specialix. 
-	  (Mostly fixed now, I think. Tell me if you encounter this!)
-
-  Bugs & restrictions:
-
-	- Arbitrary baud rates. Requires firmware update. (-> Specialix)
-
-	- Low latency (mostly firmware, -> Specialix)
