    lantiq: ltq-tapi: add customer pulse digit time
    
    With this patch you can change the pulse digit time by loading the Lantiq
    FXS driver kernel module called ltq-tapi. This is relevant for old
    rotaryphones that uses pulsedialing.
    
    The default values are:
    30-80ms for the low pulse
    30-80ms for the high pulse
    300ms for minimum Interdigit time
    
    this is OK but on some Phones it can be usefull to customize the values
    If you want to change the values to high and low pulse to 40-90ms and
    minimum interdigit time to 400ms
    
    than change /etc/modules.d/20-ltq-tapi to (without linebrakes):
    drv_tapi min_digit_low=40  min_digit_high=90 max_digit_low=40 \
    max_digit_high=90 min_interdigit=400
