staging: remove isdn capi drivers

As described in drivers/staging/isdn/TODO, the drivers are all
assumed to be unmaintained and unused now, with gigaset being the
last one to stop being maintained after Paul Bolle lost access
to an ISDN network.

The CAPI subsystem remains for now, as it is still required by
bluetooth/cmtp.

-================================
-Driver for active AVM Controller
-================================
-
-The driver provides a kernel capi2.0 Interface (kernelcapi) and
-on top of this a User-Level-CAPI2.0-interface (capi)
-and a driver to connect isdn4linux with CAPI2.0 (capidrv).
-The lowlevel interface can be used to implement a CAPI2.0
-also for passive cards since July 1999.
-
-The author can be reached at calle@calle.in-berlin.de.
-The command avmcapictrl is part of the isdn4k-utils.
-t4-files can be found at ftp://ftp.avm.de/cardware/b1/linux/firmware
-
-Currently supported cards:
-
-	- B1 ISA (all versions)
-	- B1 PCI
-	- T1/T1B (HEMA card)
-	- M1
-	- M2
-	- B1 PCMCIA
-
-Installing
-----------
-
-You need at least /dev/capi20 to load the firmware.
-
-::
-
-    mknod /dev/capi20 c 68 0
-    mknod /dev/capi20.00 c 68 1
-    mknod /dev/capi20.01 c 68 2
-    .
-    .
-    .
-    mknod /dev/capi20.19 c 68 20
-
-Running
--------
-
-To use the card you need the t4-files to download the firmware.
-AVM GmbH provides several t4-files for the different D-channel
-protocols (b1.t4 for Euro-ISDN). Install these file in /lib/isdn.
-
-if you configure as modules load the modules this way::
-
-    insmod /lib/modules/current/misc/capiutil.o
-    insmod /lib/modules/current/misc/b1.o
-    insmod /lib/modules/current/misc/kernelcapi.o
-    insmod /lib/modules/current/misc/capidrv.o
-    insmod /lib/modules/current/misc/capi.o
-
-if you have an B1-PCI card load the module b1pci.o::
-
-    insmod /lib/modules/current/misc/b1pci.o
-
-and load the firmware with::
-
-    avmcapictrl load /lib/isdn/b1.t4 1
-
-if you have an B1-ISA card load the module b1isa.o
-and add the card by calling::
-
-    avmcapictrl add 0x150 15
-
-and load the firmware by calling::
-
-    avmcapictrl load /lib/isdn/b1.t4 1
-
-if you have an T1-ISA card load the module t1isa.o
-and add the card by calling::
-
-    avmcapictrl add 0x450 15 T1 0
-
-and load the firmware by calling::
-
-    avmcapictrl load /lib/isdn/t1.t4 1
-
-if you have an PCMCIA card (B1/M1/M2) load the module b1pcmcia.o
-before you insert the card.
-
-Leased Lines with B1
---------------------
-
-Init card and load firmware.
-
-For an D64S use "FV: 1" as phone number
-
-For an D64S2 use "FV: 1" and "FV: 2" for multilink
-or "FV: 1,2" to use CAPI channel bundling.

-GigaSet 307x Device Driver
-==========================
-
-1.   Requirements
-=================
-
-1.1. Hardware
--------------
-
-     This driver supports the connection of the Gigaset 307x/417x family of
-     ISDN DECT bases via Gigaset M101 Data, Gigaset M105 Data or direct USB
-     connection. The following devices are reported to be compatible:
-
-     Bases:
-       - Siemens Gigaset 3070/3075 isdn
-       - Siemens Gigaset 4170/4175 isdn
-       - Siemens Gigaset SX205/255
-       - Siemens Gigaset SX353
-       - T-Com Sinus 45 [AB] isdn
-       - T-Com Sinus 721X[A] [SE]
-       - Vox Chicago 390 ISDN (KPN Telecom)
-
-     RS232 data boxes:
-       - Siemens Gigaset M101 Data
-       - T-Com Sinus 45 Data 1
-
-     USB data boxes:
-       - Siemens Gigaset M105 Data
-       - Siemens Gigaset USB Adapter DECT
-       - T-Com Sinus 45 Data 2
-       - T-Com Sinus 721 data
-       - Chicago 390 USB (KPN)
-
-     See also http://www.erbze.info/sinus_gigaset.htm
-       (archived at https://web.archive.org/web/20100717020421/http://www.erbze.info:80/sinus_gigaset.htm ) and
-	http://gigaset307x.sourceforge.net/
-
-     We had also reports from users of Gigaset M105 who could use the drivers
-     with SX 100 and CX 100 ISDN bases (only in unimodem mode, see section 2.5.)
-     If you have another device that works with our driver, please let us know.
-
-     Chances of getting an USB device to work are good if the output of::
-
-	lsusb
-
-     at the command line contains one of the following::
-
-	ID 0681:0001
-	ID 0681:0002
-	ID 0681:0009
-	ID 0681:0021
-	ID 0681:0022
-
-1.2. Software
--------------
-
-     The driver works with the Kernel CAPI subsystem and can be used with any
-     software which is able to use CAPI 2.0 for ISDN connections (voice or data).
-
-     There are some user space tools available at
-     https://sourceforge.net/projects/gigaset307x/
-     which provide access to additional device specific functions like SMS,
-     phonebook or call journal.
-
-
-2.   How to use the driver
-==========================
-
-2.1. Modules
-------------
-
-     For the devices to work, the proper kernel modules have to be loaded.
-     This normally happens automatically when the system detects the USB
-     device (base, M105) or when the line discipline is attached (M101). It
-     can also be triggered manually using the modprobe(8) command, for example
-     for troubleshooting or to pass module parameters.
-
-     The module ser_gigaset provides a serial line discipline N_GIGASET_M101
-     which uses the regular serial port driver to access the device, and must
-     therefore be attached to the serial device to which the M101 is connected.
-     The ldattach(8) command (included in util-linux-ng release 2.14 or later)
-     can be used for that purpose, for example::
-
-	ldattach GIGASET_M101 /dev/ttyS1
-
-     This will open the device file, attach the line discipline to it, and
-     then sleep in the background, keeping the device open so that the line
-     discipline remains active. To deactivate it, kill the daemon, for example
-     with::
-
-	killall ldattach
-
-     before disconnecting the device. To have this happen automatically at
-     system startup/shutdown on an LSB compatible system, create and activate
-     an appropriate LSB startup script /etc/init.d/gigaset. (The init name
-     'gigaset' is officially assigned to this project by LANANA.)
-     Alternatively, just add the 'ldattach' command line to /etc/rc.local.
-
-     The modules accept the following parameters:
-
-	=============== ========== ==========================================
-	Module		Parameter  Meaning
-
-	gigaset		debug	   debug level (see section 3.2.)
-
-			startmode  initial operation mode (see section 2.5.):
-	bas_gigaset )		   1=CAPI (default), 0=Unimodem
-	ser_gigaset )
-	usb_gigaset )	cidmode    initial Call-ID mode setting (see section
-				   2.5.): 1=on (default), 0=off
-
-	=============== ========== ==========================================
-
-     Depending on your distribution you may want to create a separate module
-     configuration file like /etc/modprobe.d/gigaset.conf for these.
-
-2.2. Device nodes for user space programs
------------------------------------------
-
-     The device can be accessed from user space (eg. by the user space tools
-     mentioned in 1.2.) through the device nodes:
-
-     - /dev/ttyGS0 for M101 (RS232 data boxes)
-     - /dev/ttyGU0 for M105 (USB data boxes)
-     - /dev/ttyGB0 for the base driver (direct USB connection)
-
-     If you connect more than one device of a type, they will get consecutive
-     device nodes, eg. /dev/ttyGU1 for a second M105.
-
-     You can also set a "default device" for the user space tools to use when
-     no device node is given as parameter, by creating a symlink /dev/ttyG to
-     one of them, eg.::
-
-	ln -s /dev/ttyGB0 /dev/ttyG
-
-     The devices accept the following device specific ioctl calls
-     (defined in gigaset_dev.h):
-
-     ``ioctl(int fd, GIGASET_REDIR, int *cmd);``
-
-     If cmd==1, the device is set to be controlled exclusively through the
-     character device node; access from the ISDN subsystem is blocked.
-
-     If cmd==0, the device is set to be used from the ISDN subsystem and does
-     not communicate through the character device node.
-
-     ``ioctl(int fd, GIGASET_CONFIG, int *cmd);``
-
-     (ser_gigaset and usb_gigaset only)
-
-     If cmd==1, the device is set to adapter configuration mode where commands
-     are interpreted by the M10x DECT adapter itself instead of being
-     forwarded to the base station. In this mode, the device accepts the
-     commands described in Siemens document "AT-Kommando Alignment M10x Data"
-     for setting the operation mode, associating with a base station and
-     querying parameters like field strengh and signal quality.
-
-     Note that there is no ioctl command for leaving adapter configuration
-     mode and returning to regular operation. In order to leave adapter
-     configuration mode, write the command ATO to the device.
-
-     ``ioctl(int fd, GIGASET_BRKCHARS, unsigned char brkchars[6]);``
-
-     (usb_gigaset only)
-
-     Set the break characters on an M105's internal serial adapter to the six
-     bytes stored in brkchars[]. Unused bytes should be set to zero.
-
-     ioctl(int fd, GIGASET_VERSION, unsigned version[4]);
-     Retrieve version information from the driver. version[0] must be set to
-     one of:
-
-     - GIGVER_DRIVER: retrieve driver version
-     - GIGVER_COMPAT: retrieve interface compatibility version
-     - GIGVER_FWBASE: retrieve the firmware version of the base
-
-     Upon return, version[] is filled with the requested version information.
-
-2.3. CAPI
----------
-
-     The devices will show up as CAPI controllers as soon as the
-     corresponding driver module is loaded, and can then be used with
-     CAPI 2.0 kernel and user space applications. For user space access,
-     the module capi.ko must be loaded.
-
-     Most distributions handle loading and unloading of the various CAPI
-     modules automatically via the command capiinit(1) from the capi4k-utils
-     package or a similar mechanism. Note that capiinit(1) cannot unload the
-     Gigaset drivers because it doesn't support more than one module per
-     driver.
-
-2.5. Unimodem mode
-------------------
-
-     In this mode the device works like a modem connected to a serial port
-     (the /dev/ttyGU0, ... mentioned above) which understands the commands::
-
-	 ATZ                 init, reset
-	     => OK or ERROR
-	 ATD
-	 ATDT                dial
-	     => OK, CONNECT,
-		BUSY,
-		NO DIAL TONE,
-		NO CARRIER,
-		NO ANSWER
-	 <pause>+++<pause>   change to command mode when connected
-	 ATH                 hangup
-
-     You can use some configuration tool of your distribution to configure this
-     "modem" or configure pppd/wvdial manually. There are some example ppp
-     configuration files and chat scripts in the gigaset-VERSION/ppp directory
-     in the driver packages from https://sourceforge.net/projects/gigaset307x/.
-     Please note that the USB drivers are not able to change the state of the
-     control lines. This means you must use "Stupid Mode" if you are using
-     wvdial or you should use the nocrtscts option of pppd.
-     You must also assure that the ppp_async module is loaded with the parameter
-     flag_time=0. You can do this e.g. by adding a line like::
-
-	options ppp_async flag_time=0
-
-     to an appropriate module configuration file, like::
-
-	/etc/modprobe.d/gigaset.conf.
-
-     Unimodem mode is needed for making some devices [e.g. SX100] work which
-     do not support the regular Gigaset command set. If debug output (see
-     section 3.2.) shows something like this when dialing::
-
-	 CMD Received: ERROR
-	 Available Params: 0
-	 Connection State: 0, Response: -1
-	 gigaset_process_response: resp_code -1 in ConState 0 !
-	 Timeout occurred
-
-     then switching to unimodem mode may help.
-
-     If you have installed the command line tool gigacontr, you can enter
-     unimodem mode using::
-
-	 gigacontr --mode unimodem
-
-     You can switch back using::
-
-	 gigacontr --mode isdn
-
-     You can also put the driver directly into Unimodem mode when it's loaded,
-     by passing the module parameter startmode=0 to the hardware specific
-     module, e.g.::
-
-	modprobe usb_gigaset startmode=0
-
-     or by adding a line like::
-
-	options usb_gigaset startmode=0
-
-     to an appropriate module configuration file, like::
-
-	/etc/modprobe.d/gigaset.conf
-
-2.6. Call-ID (CID) mode
------------------------
-
-     Call-IDs are numbers used to tag commands to, and responses from, the
-     Gigaset base in order to support the simultaneous handling of multiple
-     ISDN calls. Their use can be enabled ("CID mode") or disabled ("Unimodem
-     mode"). Without Call-IDs (in Unimodem mode), only a very limited set of
-     functions is available. It allows outgoing data connections only, but
-     does not signal incoming calls or other base events.
-
-     DECT cordless data devices (M10x) permanently occupy the cordless
-     connection to the base while Call-IDs are activated. As the Gigaset
-     bases only support one DECT data connection at a time, this prevents
-     other DECT cordless data devices from accessing the base.
-
-     During active operation, the driver switches to the necessary mode
-     automatically. However, for the reasons above, the mode chosen when
-     the device is not in use (idle) can be selected by the user.
-
-     - If you want to receive incoming calls, you can use the default
-       settings (CID mode).
-     - If you have several DECT data devices (M10x) which you want to use
-       in turn, select Unimodem mode by passing the parameter "cidmode=0" to
-       the appropriate driver module (ser_gigaset or usb_gigaset).
-
-     If you want both of these at once, you are out of luck.
-
-     You can also use the tty class parameter "cidmode" of the device to
-     change its CID mode while the driver is loaded, eg.::
-
-	echo 0 > /sys/class/tty/ttyGU0/cidmode
-
-2.7. Dialing Numbers
---------------------
-provided by an application for dialing out must
-     be a public network number according to the local dialing plan, without
-     any dial prefix for getting an outside line.
-
-     Internal calls can be made by providing an internal extension number
-     prefixed with ``**`` (two asterisks) as the called party number. So to dial
-     eg. the first registered DECT handset, give ``**11`` as the called party
-     number. Dialing ``***`` (three asterisks) calls all extensions
-     simultaneously (global call).
-
-     Unimodem mode does not support internal calls.
-
-2.8. Unregistered Wireless Devices (M101/M105)
-----------------------------------------------
-
-     The main purpose of the ser_gigaset and usb_gigaset drivers is to allow
-     the M101 and M105 wireless devices to be used as ISDN devices for ISDN
-     connections through a Gigaset base. Therefore they assume that the device
-     is registered to a DECT base.
-
-     If the M101/M105 device is not registered to a base, initialization of
-     the device fails, and a corresponding error message is logged by the
-     driver. In that situation, a restricted set of functions is available
-     which includes, in particular, those necessary for registering the device
-     to a base or for switching it between Fixed Part and Portable Part
-     modes. See the gigacontr(8) manpage for details.
-
-3.   Troubleshooting
-====================
-
-3.1. Solutions to frequently reported problems
-----------------------------------------------
-
-     Problem:
-	You have a slow provider and isdn4linux gives up dialing too early.
-     Solution:
-	Load the isdn module using the dialtimeout option. You can do this e.g.
-	by adding a line like::
-
-	   options isdn dialtimeout=15
-
-	to /etc/modprobe.d/gigaset.conf or a similar file.
-
-     Problem:
-	The isdnlog program emits error messages or just doesn't work.
-     Solution:
-	Isdnlog supports only the HiSax driver. Do not attempt to use it with
-	other drivers such as Gigaset.
-
-     Problem:
-	You have two or more DECT data adapters (M101/M105) and only the
-	first one you turn on works.
-     Solution:
-	Select Unimodem mode for all DECT data adapters. (see section 2.5.)
-
-     Problem:
-	Messages like this::
-
-	    usb_gigaset 3-2:1.0: Could not initialize the device.
-
-	appear in your syslog.
-     Solution:
-	Check whether your M10x wireless device is correctly registered to the
-	Gigaset base. (see section 2.7.)
-
-3.2. Telling the driver to provide more information
----------------------------------------------------
-     Building the driver with the "Gigaset debugging" kernel configuration
-     option (CONFIG_GIGASET_DEBUG) gives it the ability to produce additional
-     information useful for debugging.
-
-     You can control the amount of debugging information the driver produces by
-     writing an appropriate value to /sys/module/gigaset/parameters/debug,
-     e.g.::
-
-	echo 0 > /sys/module/gigaset/parameters/debug
-
-     switches off debugging output completely,
-
-     ::
-
-	echo 0x302020 > /sys/module/gigaset/parameters/debug
-
-     enables a reasonable set of debugging output messages. These values are
-     bit patterns where every bit controls a certain type of debugging output.
-     See the constants DEBUG_* in the source file gigaset.h for details.
-
-     The initial value can be set using the debug parameter when loading the
-     module "gigaset", e.g. by adding a line::
-
-	options gigaset debug=0
-
-     to your module configuration file, eg. /etc/modprobe.d/gigaset.conf
-
-     Generated debugging information can be found
-     - as output of the command::
-
-	 dmesg
-
-     - in system log files written by your syslog daemon, usually
-       in /var/log/, e.g. /var/log/messages.
-
-3.3. Reporting problems and bugs
---------------------------------
-     If you can't solve problems with the driver on your own, feel free to
-     use one of the forums, bug trackers, or mailing lists on
-
-	 https://sourceforge.net/projects/gigaset307x
-
-     or write an electronic mail to the maintainers.
-
-     Try to provide as much information as possible, such as
-
-     - distribution
-     - kernel version (uname -r)
-     - gcc version (gcc --version)
-     - hardware architecture (uname -m, ...)
-     - type and firmware version of your device (base and wireless module,
-       if any)
-     - output of "lsusb -v" (if using an USB device)
-     - error messages
-     - relevant system log messages (it would help if you activate debug
-       output as described in 3.2.)
-
-     For help with general configuration problems not specific to our driver,
-     such as isdn4linux and network configuration issues, please refer to the
-     appropriate forums and newsgroups.
-
-3.4. Reporting problem solutions
---------------------------------
-     If you solved a problem with our drivers, wrote startup scripts for your
-     distribution, ... feel free to contact us (using one of the places
-     mentioned in 3.3.). We'd like to add scripts, hints, documentation
-     to the driver and/or the project web page.

-
-1. About the driver
-===================
-
-   The drivers/isdn/hysdn subdir contains a driver for HYPERCOPEs active
-   PCI isdn cards Champ, Ergo and Metro. To enable support for this cards
-   enable ISDN support in the kernel config and support for HYSDN cards in
-   the active cards submenu. The driver may only be compiled and used if
-   support for loadable modules and the process filesystem have been enabled.
-
-   These cards provide two different interfaces to the kernel. Without the
-   optional CAPI 2.0 support, they register as ethernet card. IP-routing
-   to a ISDN-destination is performed on the card itself. All necessary
-   handlers for various protocols like ppp and others as well as config info
-   and firmware may be fetched from Hypercopes WWW-Site www.hypercope.de.
-
-   With CAPI 2.0 support enabled, the card can also be used as a CAPI 2.0
-   compliant devices with either CAPI 2.0 applications
-   (check isdn4k-utils) or -using the capidrv module- as a regular
-   isdn4linux device. This is done via the same mechanism as with the
-   active AVM cards and in fact uses the same module.
-
-
-2. Loading/Unloading the driver
-===============================
-
-   The module has no command line parameters and auto detects up to 10 cards
-   in the id-range 0-9.
-   If a loaded driver shall be unloaded all open files in the /proc/net/hysdn
-   subdir need to be closed and all ethernet interfaces allocated by this
-   driver must be shut down. Otherwise the module counter will avoid a module
-   unload.
-
-   If you are using the CAPI 2.0-interface, make sure to load/modprobe the
-   kernelcapi-module first.
-
-   If you plan to use the capidrv-link to isdn4linux, make sure to load
-   capidrv.o after all modules using this driver (i.e. after hysdn and
-   any avm-specific modules).
-
-3. Entries in the /proc filesystem
-==================================
-
-   When the module has been loaded it adds the directory hysdn in the
-   /proc/net tree. This directory contains exactly 2 file entries for each
-   card. One is called cardconfX and the other cardlogX, where X is the
-   card id number from 0 to 9.
-   The cards are numbered in the order found in the PCI config data.
-
-4. The /proc/net/hysdn/cardconfX file
-=====================================
-
-   This file may be read to get by everyone to get info about the cards type,
-   actual state, available features and used resources.
-   The first 3 entries (id, bus and slot) are PCI info fields, the following
-   type field gives the information about the cards type:
-
-   - 4 -> Ergo card (server card with 2 b-chans)
-   - 5 -> Metro card (server card with 4 or 8 b-chans)
-   - 6 -> Champ card (client card with 2 b-chans)
-
-   The following 3 fields show the hardware assignments for irq, iobase and the
-   dual ported memory (dp-mem).
-
-   The fields b-chans and fax-chans announce the available card resources of
-   this types for the user.
-
-   The state variable indicates the actual drivers state for this card with the
-   following assignments.
-
-   - 0 -> card has not been booted since driver load
-   - 1 -> card booting is actually in progess
-   - 2 -> card is in an error state due to a previous boot failure
-   - 3 -> card is booted and active
-
-   And the last field (device) shows the name of the ethernet device assigned
-   to this card. Up to the first successful boot this field only shows a -
-   to tell that no net device has been allocated up to now. Once a net device
-   has been allocated it remains assigned to this card, even if a card is
-   rebooted and an boot error occurs.
-
-   Writing to the cardconfX file boots the card or transfers config lines to
-   the cards firmware. The type of data is automatically detected when the
-   first data is written. Only root has write access to this file.
-   The firmware boot files are normally called hyclient.pof for client cards
-   and hyserver.pof for server cards.
-   After successfully writing the boot file, complete config files or single
-   config lines may be copied to this file.
-   If an error occurs the return value given to the writing process has the
-   following additional codes (decimal):
-
-   ==== ============================================
-   1000 Another process is currently bootng the card
-   1001 Invalid firmware header
-   1002 Boards dual-port RAM test failed
-   1003 Internal firmware handler error
-   1004 Boot image size invalid
-   1005 First boot stage (bootstrap loader) failed
-   1006 Second boot stage failure
-   1007 Timeout waiting for card ready during boot
-   1008 Operation only allowed in booted state
-   1009 Config line too long
-   1010 Invalid channel number
-   1011 Timeout sending config data
-   ==== ============================================
-
-   Additional info about error reasons may be fetched from the log output.
-
-5. The /proc/net/hysdn/cardlogX file
-====================================
-
-   The cardlogX file entry may be opened multiple for reading by everyone to
-   get the cards and drivers log data. Card messages always start with the
-   keyword LOG. All other lines are output from the driver.
-   The driver log data may be redirected to the syslog by selecting the
-   appropriate bitmask. The cards log messages will always be send to this
-   interface but never to the syslog.
-
-   A root user may write a decimal or hex (with 0x) value t this file to select
-   desired output options. As mentioned above the cards log dat is always
-   written to the cardlog file independent of the following options only used
-   to check and debug the driver itself:
-
-   For example::
-
-	echo "0x34560078" > /proc/net/hysdn/cardlog0
-
-   to output the hex log mask 34560078 for card 0.
-
-   The written value is regarded as an unsigned 32-Bit value, bit ored for
-   desired output. The following bits are already assigned:
-
-   ==========   ============================================================
-   0x80000000   All driver log data is alternatively via syslog
-   0x00000001   Log memory allocation errors
-   0x00000010   Firmware load start and close are logged
-   0x00000020   Log firmware record parser
-   0x00000040   Log every firmware write actions
-   0x00000080   Log all card related boot messages
-   0x00000100   Output all config data sent for debugging purposes
-   0x00000200   Only non comment config lines are shown wth channel
-   0x00000400   Additional conf log output
-   0x00001000   Log the asynchronous scheduler actions (config and log)
-   0x00100000   Log all open and close actions to /proc/net/hysdn/card files
-   0x00200000   Log all actions from /proc file entries
-   0x00010000   Log network interface init and deinit
-   ==========   ============================================================
