Andreas Eversberg 07003408fc mISDN: Added support for fragmentation of E1 interfaces of hfcmulti driver.
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.

Joe Perches 475be4d85a isdn: whitespace coding style cleanup
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.

Karsten Keil db9bb63a1b mISDN: Add XHFC support for embedded Speech-Design board to hfcmulti
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.

Andreas Eversberg 8dd2f36f31 mISDN: Add feature via MISDN_CTRL_FILL_EMPTY to fill fifo if empty
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.

Hannes Eder c31655fcf2 mISDN: hfcmulti: use __iomem address space modifier
Impact: make use of the __iomem address space modifier, and change u_char *,
u_short * and u_int * to void *

Fix more than 30 sparse warnings of this or similar type:
