isdn: i4l: move active-isdn drivers to staging

The icn, act2000 and pcbit drivers are all for very old hardware,
and it is highly unlikely that anyone is actually still using them
on modern kernels, if at all.

All three drivers apparently are for hardware that predates PCI
being the common connector, as they are ISA-only and active
PCI ISDN cards were widely available in the 1990s.

Looking through the git logs, it I cannot find any indication of a
patch to any of these drivers that has been tested on real hardware,
only cleanups or global API changes.

-This document describes the ACT2000 driver for the
-IBM Active 2000 ISDN card.
-
-There are 3 Types of this card available. A ISA-, MCA-, and PCMCIA-Bus
-Version. Currently, only the ISA-Bus version of the card is supported.
-However MCA and PCMCIA will follow soon.
-
-The ISA-Bus Version uses 8 IO-ports. The base port address has to be set
-manually using the DIP switches.
-
-Setting up the DIP switches for the IBM Active 2000 ISDN card:
-
-	 Note: S5 and S6 always set off!

-     off on  off off 0xcea0 
-     on  off off off 0xce60 
-     off off off off Card disabled 
-
-IRQ is configured by software. Possible values are:
-
-  3, 5, 7, 10, 11, 12, 15 and none (polled mode)
-
-
-The ACT2000 driver may either be built into the kernel or as a module.
-Initialization depends on how the driver is built:
-
-Driver built into the kernel:
-
-  The ACT2000 driver can be configured using the commandline-feature while
-  loading the kernel with LILO or LOADLIN. It accepts the following syntax:
-
-  act2000=b,p,i[,idstring]
-
-  where
-
-    b = Bus-Type      (1=ISA, 2=MCA, 3=PCMCIA)
-    p = portbase      (-1 means autoprobe)
-    i = Interrupt     (-1 means use next free IRQ, 0 means polled mode)
-
-  The idstring is an arbitrary string used for referencing the card
-  by the actctrl tool later.
-
-  Defaults used, when no parameters given at all:
-
-    1,-1,-1,""
-
-  which means: Autoprobe for an ISA card, use next free IRQ, let the
-  ISDN linklevel fill the IdString (usually "line0" for the first card).
- 
-  If you like to use more than one card, you can use the program
-  "actctrl" from the utility-package to configure additional cards.
-
-  Using the "actctrl"-utility, portbase and irq can also be changed
-  during runtime. The D-channel protocol is configured by the "dproto"
-  option of the "actctrl"-utility after loading the firmware into the
-  card's memory using the "actctrl"-utility.
-
-Driver built as module:
-
-  The module act2000.o can be configured during modprobe (insmod) by
-  appending its parameters to the modprobe resp. insmod commandline.
-  The following syntax is accepted:
-
-    act_bus=b act_port=p act_irq=i act_id=idstring
-
-  where b, p, i and idstring have the same meanings as the parameters
-  described for the builtin version above.
-
-  Using the "actctrl"-utility, the same features apply to the modularized
-  version as to the kernel-builtin one. (i.e. loading of firmware and
-  configuring the D-channel protocol)
-
-Loading the firmware into the card:
-
-  The firmware is supplied together with the isdn4k-utils package. It
-  can be found in the subdirectory act2000/firmware/
-
-  Assuming you have installed the utility-package correctly, the firmware
-  will be downloaded into the card using the following command:
-
-    actctrl -d idstring load /etc/isdn/bip11.btl
-
-  where idstring is the Name of the card, given during insmod-time or
-  (for kernel-builtin driver) on the kernel commandline. If only one
-  ISDN card is used, the -d isdstrin may be omitted.
-
-  For further documentation (adding more IBM Active 2000 cards), refer to
-  the manpage actctrl.8 which is included in the isdn4k-utils package.

-The card communicates with the PC by two interfaces:
-  1. A range of 4 successive port-addresses, whose base address can be 
-     configured with the switches.
-  2. A memory window with 16KB-256KB size, which can be setup in 16k steps
-     over the whole range of 16MB. Isdn4linux only uses a 16k window.
-     The base address of the window can be configured when loading

-
-Driver built into the kernel:
-
-  The ICN driver can be configured using the commandline-feature while
-  loading the kernel with LILO or LOADLIN. It accepts the following syntax:
-
-  icn=p,m[,idstring1[,idstring2]]
-
-  where
-
-    p = portbase      (default: 0x320)
-    m = shared memory (default: 0xd0000)
-
-  When using the ICN double card (4B), you MUST define TWO idstrings.
-  idstring must start with a character! There is no way for the driver
-  to distinguish between a 2B and 4B type card. Therefore, by supplying
-  TWO idstrings, you tell the driver that you have a 4B installed.
-  
-  If you like to use more than one card, you can use the program
-  "icnctrl" from the utility-package to configure additional cards.
-  You need to configure shared memory only once, since the icn-driver
-  maps all cards into the same address-space.
-
-  Using the "icnctrl"-utility, portbase and shared memory can also be
-  changed during runtime.
-
-  The D-channel protocol is configured by loading different firmware
-  into the card's memory using the "icnctrl"-utility.
-
-
-Driver built as module:
-
-  The module icn.o can be configured during "insmod'ing" it by
-  appending its parameters to the insmod-commandline. The following

-
-Loading the firmware into the card:
-
-  The firmware is supplied together with the isdn4k-utils package. It
-  can be found in the subdirectory icnctrl/firmware/
-
-  There are 3 files:
-
-    loadpg.bin   - Image of the bootstrap loader.
-    pc_1t_ca.bin - Image of firmware for german 1TR6 protocol.
-    pc_eu_ca.bin - Image if firmware for EDSS1 (Euro-ISDN) protocol.
-
-  Assuming you have installed the utility-package correctly, the firmware
-  will be downloaded into the 2B-card using the following command:
-
-    icnctrl -d Idstring load /etc/isdn/loadpg.bin /etc/isdn/pc_XX_ca.bin
-
-  where XX is either "1t" or "eu", depending on the D-Channel protocol
-  used on your S0-bus and Idstring is the Name of the card, given during
-  insmod-time or (for kernel-builtin driver) on the kernel commandline.
-
-  To load a 4B-card, the same command is used, except a second firmware
-  file is appended to the commandline of icnctrl.
-
-  -> After downloading firmware, the two LEDs at the back cover of the card
-     (ICN-4B: 4 LEDs) must be blinking intermittently now. If a connection
-     is up, the corresponding led is lit continuously.
-
-  For further documentation (adding more ICN-cards), refer to the manpage
-  icnctrl.8 which is included in the isdn4k-utils package.

- README file for the PCBIT-D Device Driver.

-
-The PCBIT is a Euro ISDN adapter manufactured in Portugal by Octal and
-developed in cooperation with Portugal Telecom and Inesc.
-The driver interfaces with the standard kernel isdn facilities
-originally developed by Fritz Elfert in the isdn4linux project.
-
-The common versions of the pcbit board require a firmware that is 
-distributed (and copyrighted) by the manufacturer. To load this
-firmware you need "pcbitctl" available on the standard isdn4k-utils
-package or in the pcbit package available in:
-
-ftp://ftp.di.fc.ul.pt/pub/systems/Linux/isdn
-
-Known Limitations:
-
-- The board reset procedure is at the moment incorrect and will only
-allow you to load the firmware after a hard reset.
-
-- Only HDLC in B-channels is supported at the moment. There is no
-current support for X.25 in B or D channels nor LAPD in B
-channels. The main reason is that these two other protocol modes have,
-to my knowledge, very little use. If you want to see them implemented
-*do* send me a mail.
-
-- The driver often triggers errors in the board that I and the
-manufacturer believe to be caused by bugs in the firmware. The current
-version includes several procedures for error recovery that should
-allow normal operation. Plans for the future include cooperation with
-the manufacturer in order to solve this problem.

-1. Introduction
----------------
-
-The revision 2 Linux driver for SpellCaster ISA ISDN adapters is built
-upon ISDN4Linux available separately or as included in Linux 2.0 and later.
-The driver will support a maximum of 4 adapters in any one system of any
-type including DataCommute/BRI, DataCommute/PRI and TeleCommute/BRI for a
-maximum of 92 channels for host. The driver is supplied as a module in
-source form and needs to be complied before it can be used. It has been
-tested on Linux 2.0.20.
-
-1.1 What Is ISDN4Linux
-
-ISDN4Linux is a driver and set of tools used to access and use ISDN devices
-on a Linux platform in a common and standard way. It supports HDLC and PPP
-protocols and offers channel bundling and MLPPP support. To use ISDN4Linux
-you need to configure your kernel for ISDN support and get the ISDN4Linux
-tool kit from our web site.
-
-ISDN4Linux creates a channel pool from all of the available ISDN channels
-and therefore can function across adapters. When an ISDN4Linux compliant
-driver (such as ours) is loaded, all of the channels go into a pool and
-are used on a first-come first-served basis. In addition, individual
-channels can be specifically bound to particular interfaces.
-
-1.2 What is different between this driver and previous drivers?
-
-The revision 2 driver besides adopting the ISDN4Linux architecture has many
-subtle and not so subtle functional differences from previous releases. These
-include:
-	- More efficient shared memory management combined with a simpler
-	  configuration. All adapters now use only 16Kbytes of shared RAM
-	  versus between 16K and 64K. New methods for using the shared RAM
-	  allow us to utilize all of the available RAM on the adapter through
-	  only one 16K page.
-	- Better detection of available upper memory. The probing routines
-	  have been improved to better detect available shared RAM pages and
-	  used pages are now locked.
-	- Decreased loading time and a wider range of I/O ports probed.
-	  We have significantly reduced the amount of time it takes to load
-	  the driver and at the same time doubled the number of I/O ports
-	  probed increasing the likelihood of finding an adapter.
-	- We now support all ISA adapter models with a single driver instead
-	  of separate drivers for each model. The revision 2 driver supports
-	  the DataCommute/BRI, DataCommute/PRI and TeleCommute/BRI in any
-	  combination up to a maximum of four adapters per system.
-	- On board PPP protocol support has been removed in favour of the
-	  sync-PPP support used in ISDN4Linux. This means more control of
-	  the protocol parameters, faster negotiation time and a more
-	  familiar interface.
-
-1.3 How do I setup my system with the correct software to use
-    this driver release?
-
-Before you can compile, install and use the SpellCaster ISA ISDN driver, you
-must ensure that the following software is installed, configured and running:
-
-	- Linux kernel 2.0.20 or later with the required init and ps
-	  versions. Please see your distribution vendor for the correct
-	  utility packages. The latest kernel is available from
-	  ftp://sunsite.unc.edu/pub/Linux/kernel/v2.0/
-
-	- The latest modules package (modules-2.0.0.tar.gz) from
-	  ftp://sunsite.unc.edu/pub/Linux/kernel/modules-2.0.0.tar.gz
-
-	- The ISDN4Linux tools available from 
-	  ftp://ftp.franken.de/pub/isdn4linux/v2.0/isdn4k-utils-2.0.tar.gz
-	  This package may fail to compile for you so you can alternatively
-	  get a pre-compiled version from
-	  ftp://ftp.spellcast.com/pub/drivers/isdn4linux/isdn4k-bin-2.0.tar.gz
-
-
-2. Basic Operations
--------------------
-
-2.1 Unpacking and installing the driver
-
-	1. As root, create a directory in a convenient place. We suggest
-	   /usr/src/spellcaster.
-	
-	2. Unpack the archive with :
-		tar xzf sc-n.nn.tar.gz -C /usr/src/spellcaster
-	
-	3. Change directory to /usr/src/spellcaster
-
-	4. Read the README and RELNOTES files.
-
-	5. Run 'make' and if all goes well, run 'make install'.
-
-2.2 Read the man pages!!!
-
-Make sure you read the scctrl(8) and sc(4) manual pages before continuing
-any further. Type 'man 8 scctrl' and 'man 4 sc'.
-
-2.3 Installing the driver
-
-To install the driver, type '/sbin/insmod sc' as root. sc(4) details options
-you can specify but you shouldn't need to use any unless this doesn't work.
-
-Make sure the driver loaded and detected all of the adapters by typing
-'dmesg'.
-
-The driver can be configured so that it is loaded upon startup.  To do this, 
-edit the file "/etc/modules/'uname -f'/'uname -v'" and insert the driver name
-"sc" into this file.
-
-2.4 Removing the driver
-
-To remove the driver, delete any interfaces that may exist (see isdnctrl(8)
-for more on this) and then type '/sbin/rmmod sc'.
-
-2.5 What to do if it doesn't load
-
-If, when you try to install the driver, you get a message mentioning
-'register_isdn' then you do not have the ISDN4Linux system installed. Please
-make sure that ISDN support is configured in the kernel.
-
-If you get a message that says 'initialization of sc failed', then the
-driver failed to detect an adapter or failed to find resources needed such
-as a free IRQ line or shared memory segment. If you are sure there are free
-resources available, use the insmod options detailed in sc(4) to override
-the probing function.  
-
-Upon testing, the following problem was noted, the driver would load without
-problems, but the board would not respond beyond that point.  When a check was 
-done with 'cat /proc/interrupts' the interrupt count for sc was 0.  In the event 
-of this problem, change the BIOS settings so that the interrupts in question are
-reserved for ISA use only.   
-
-
-2.6 How to setup ISDN4Linux with the driver
-
-There are three main configurations which you can use with the driver:
-
-A)	Basic HDLC connection
-B)	PPP connection
-C)	MLPPP connection
-
-It should be mentioned here that you may also use a tty connection if you
-desire. The Documentation directory of the isdn4linux subsystem offers good
-documentation on this feature.
-
-A) 10 steps to the establishment of a basic HDLC connection
------------------------------------------------------------
-
-- please open the isdn-hdlc file in the examples directory and follow along...
-	
-	This file is a script used to configure a BRI ISDN TA to establish a 
-	basic HDLC connection between its two channels.  Two network 
-	interfaces are created and two routes added between the channels.
-
-	i)   using the isdnctrl utility, add an interface with "addif" and 
-	     name it "isdn0"
-	ii)  add the outgoing and inbound telephone numbers
-	iii) set the Layer 2 protocol to hdlc
-	iv)  set the eaz of the interface to be the phone number of that 
-	     specific channel
-	v)   to turn the callback features off, set the callback to "off" and
-	     the callback delay (cbdelay) to 0.
-	vi)  the hangup timeout can be set to a specified number of seconds
-	vii) the hangup upon incoming call can be set on or off 
-	viii) use the ifconfig command to bring up the network interface with 
-	      a specific IP address and point to point address
-	ix)  add a route to the IP address through the isdn0 interface
-	x)   a ping should result in the establishment of the connection
-
-	
-B) Establishment of a PPP connection
-------------------------------------
-
-- please open the isdn-ppp file in the examples directory and follow along...
-	
-	This file is a script used to configure a BRI ISDN TA to establish a 
-	PPP connection 	between the two channels.  The file is almost 
-	identical to the HDLC connection example except that the packet 
-	encapsulation type has to be set.
-	
-	use the same procedure as in the HDLC connection from steps i) to 
-	iii) then, after the Layer 2 protocol is set, set the encapsulation 
-	"encap" to syncppp. With this done, the rest of the steps, iv) to x) 
-	can be followed from above.
-
-	Then, the ipppd (ippp daemon) must be setup:
-	
-	xi)   use the ipppd function found in /sbin/ipppd to set the following:
-	xii)  take out (minus) VJ compression and bsd compression
-	xiii) set the mru size to 2000
-	xiv)  link the two /dev interfaces to the daemon
-
-NOTE:  A "*" in the inbound telephone number specifies that a call can be 
-accepted on any number.
-
-C) Establishment of a MLPPP connection
---------------------------------------
-
-- please open the isdn-mppp file in the examples directory and follow along...
-	
-	This file is a script used to configure a BRI ISDN TA to accept a 
-	Multi Link PPP connection. 
-	
-	i)   using the isdnctrl utility, add an interface with "addif" and 
-	     name it "ippp0"
-	ii)  add the inbound telephone number
-	iii) set the Layer 2 protocol to hdlc and the Layer 3 protocol to 
-	     trans (transparent)
-	iv)  set the packet encapsulation to syncppp
-	v)   set the eaz of the interface to be the phone number of that 
-	     specific channel
-	vi)  to turn the callback features off, set the callback to "off" and
-	     the callback delay (cbdelay) to 0.
-	vi)  the hangup timeout can be set to a specified number of seconds
-	vii) the hangup upon incoming call can be set on or off 
-	viii) add a slave interface and name it "ippp32" for example
-	ix)  set the similar parameters for the ippp32 interface
-	x)   use the ifconfig command to bring-up the ippp0 interface with a 
-	     specific IP address and point to point address
-	xi)  add a route to the IP address through the ippp0 interface
-	xii) use the ipppd function found in /sbin/ipppd to set the following:
-	xiii) take out (minus) bsd compression
-	xiv) set the mru size to 2000
-	xv)  add (+) the multi-link function "+mp"
-	xvi)  link the two /dev interfaces to the daemon
-
-NOTE:  To use the MLPPP connection to dial OUT to a MLPPP connection, change 
-the inbound telephone numbers to the outgoing telephone numbers of the MLPPP 
-host.

-3. Beta Change Summaries and Miscellaneous Notes
-------------------------------------------------
-When using the "scctrl" utility to upload firmware revisions on the board,
-please note that the byte count displayed at the end of the operation may be
-different from the total number of bytes in the "dcbfwn.nn.sr" file. Please
-disregard the displayed byte count.
-
-It was noted that in Beta Release 1, the module would fail to load and result
-in a segmentation fault when 'insmod'ed. This problem was created when one of
-the isdn4linux parameters, (isdn_ctrl, data field) was filled in. In some
-cases, this data field was NULL, and was left unchecked, so when it was
-referenced... segv. The bug has been fixed around line 63-68 of event.c.
