* mISDN: Added support for fragmentation of E1 interfaces of hfcmulti driver.Andreas Eversberg2012-04-26
| | | | | | | | | | Fragmentation is usefull if multiple devices are connected to an E1 interface. Each fragment will have a subset of the available timeslots. These devices require a cascde connection or a multiplexer. Signed-off-by: Andreas Eversberg <jolly@eversberg.eu> Signed-off-by: Karsten Keil <keil@b1-systems.de> Signed-off-by: David S.

* mISDN: Rework of LED status display for HFC-4S/8S/E1 cards.Andreas Eversberg2012-04-26
| | | | | | | | | | LEDs will show RED if layer 1 is disabled or fails. LEDs will show GREEN if layer 1 is active. LEDs will blink if traffic on D-channel.

* isdn: whitespace coding style cleanupJoe Perches2012-02-21
| | | | | | | | | | | | | | | isdn source code uses a not-current coding style. Update the coding style used on a per-line basis so that git diff -w shows only elided blank lines at EOF. Done with emacs and some scripts and some typing. Built x86 allyesconfig. No detected change in objdump -d or size. Signed-off-by: Joe Perches <joe@perches.com>
* mISDN: Add XHFC support for embedded Speech-Design board to hfcmultiKarsten Keil2009-05-25
| | | | | | | | | | New version without emulating arch specific stuff for the other architectures, the special IO and init functions for the 8xx microcontroller are in a separate include file.

* mISDN: Echo canceler now gets delay information from hardwareAndreas Eversberg2009-05-25
| | | | | | | | | Added tx-fifo information for calculation of current delay to sync tx and rx streams for echo canceler. Signed-off-by: Andreas Eversberg <andreas@eversberg.eu> Signed-off-by: Karsten Keil <keil@b1-systems.de> Signed-off-by: David S. Miller <davem@davemloft.net>
* mISDN: Add watchdog functionality to hfcmulti driverAndreas Eversberg2009-05-25
| | | | | | | | | This patch was made by Titus Moldovan and provides IOCTL functions for enabling and disabling the controller's built in watchdog. The use is optional.

* mISDN: Add ISDN sample clock API to mISDN coreAndreas Eversberg2009-01-09
| | | | | | | | Add ISDN sample clock API to mISDN core (new file clock.c) hfcmulti and mISDNdsp use clock API. Signed-off-by: Andreas Eversberg <andreas@eversberg.eu> Signed-off-by: Karsten Keil <kkeil@suse.de>
* mISDN: Add feature via MISDN_CTRL_FILL_EMPTY to fill fifo if emptyAndreas Eversberg2009-01-09
| | | | | | | | | | | | This prevents underrun of fifo when filled and in case of an underrun it prevents subsequent underruns due to jitter. Improve dsp, so buffers are kept filled with a certain delay, so moderate jitter will not cause underrun all the time -> the audio quality is highly improved. tones are not interrupted by gaps anymore, except when CPU is stalling or in high load.
