       NAME
             dma_enable - enable recognition of hardware requests on a DMA
             channel

       SYNOPSIS
             #include <sys/dma.h>
             #include <sys/ddi.h>
             void dma_enable(int chan);

          Arguments
             chan      Channel to be enabled.

       DESCRIPTION
             dma_enable enables recognition of hardware requests on the DMA
             channel chan.

          Return Values
             None.

       USAGE
             The channel should have been programmed previously by
             dma_prog(D3).

          Level
             Initialization, Base or Interrupt.
