     Because the DMA transfers are going to be relatively small (< 2kbyte),
     the DMA can handle the data rate, even when the frequency of the laser
     driver pulse is set to its maximum value. (200 kHz)

     The synchronization will be done by connecting the generated pulse to
     the DMA's SYNC input. Although, to support 2 or 1 channel scenarios, we
     need to use the util_axis_syncgen module to make sure that the DMA
     catches the pulse, in cases when the pulse width is too narrow. (SYNC is
     captures when valid and ready is asserted)

     Also we have to reset the cpack IP before each pulse, to keep the DMA buffer's
     relative starting point in time fixed, when only 2 or 1 channel is
     active.
