Merge tag 'staging-5.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging and IIO updates from Greg KH:
"Here is the big staging/iio driver patches for 5.6-rc1
Included in here are:
- lots of new IIO drivers and updates for that subsystem
- the usual huge quantity of minor cleanups for staging drivers
- removal of the following staging drivers:
- isdn/avm
- isdn/gigaset
- isdn/hysdn
- octeon-usb
- octeon ethernet
Overall we deleted far more lines than we added, removing over 40k of
old and obsolete driver code.
All of these changes have been in linux-next for a while with no
reported issues"

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.

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.
