    I think for now it would be enough to mark the driver X86 only, it's the
    only architecture which was tested up to now. I have a pegasus PPC
    now in my office since yesterday and will fix the endian issue hopefully
    this week.

    This is a special hook for asterisk time synchronation, which maybe can
    removed for now, the 125 us is only enabled if this hook is activated.

    Andreas can you please do this part ?
