*
* poll:
* NOTE: only one poll value must be given for all cards
* Give the number of samples for each fifo process.
* By default 128 is used. Decrease to reduce delay, increase to
* reduce cpu load. If unsure, don't mess with it!
* A value of 128 will use controller's interrupt. Other values will
* use kernel timer, because the controller will not allow lower values
* than 128.
* Also note that the value depends on the kernel timer frequency.
* If kernel uses a frequency of 1000 Hz, steps of 8 samples are possible.
* If the kernel uses 100 Hz, steps of 80 samples are possible.
* If the kernel uses 300 Hz, steps of about 26 samples are possible.

* Quick API description:
*
* A clock source registers using mISDN_register_clock:
* name = text string to name clock source
* priority = value to priorize clock sources (0 = default)
* ctl = callback function to enable/disable clock source
* priv = private pointer of clock source
* return = pointer to clock source structure;
*
* Note: Callback 'ctl' can be called before mISDN_register_clock returns!
* Also it can be called during mISDN_unregister_clock.
*
* A clock source calls mISDN_clock_update with given samples elapsed, if
* enabled. If function call is delayed, tv must be set with the timestamp
* of the actual event.
*
* A clock source unregisters using mISDN_unregister_clock.
*
* To get current clock, call mISDN_clock_get. The signed short value
* counts the number of samples since. Time since last clock event is added.
*
