NAME
       ddi_dma_unbind_handle - unbinds the address in a DMA handle

SYNOPSIS
       #include <sys/ddi.h>
       #include <sys/sunddi.h>

       int ddi_dma_unbind_handle(ddi_dma_handle_t handle);

PARAMETERS
       handle    The   DMA   handle   previously   allocated   by  a  call  to
                 ddi_dma_alloc_handle(9F).


INTERFACE LEVEL
       Solaris DDI specific (Solaris DDI).

DESCRIPTION
       ddi_dma_unbind_handle() frees all  DMA  resources  associated  with  an
       existing  DMA  handle. When a DMA transfer completes, the driver should
       call ddi_dma_unbind_handle() to free system DMA  resources  established
       by  a  call  to  ddi_dma_buf_bind_handle(9F)  or ddi_dma_addr_bind_han‐
       dle(9F). ddi_dma_unbind_handle() does an implicit ddi_dma_sync(9F) mak‐
       ing further synchronization steps unnecessary.

RETURN VALUES
       DDI_SUCCESS    on success


       DDI_FAILURE    on failure


CONTEXT
       ddi_dma_unbind_handle()  can  be called from user, kernel, or interrupt
       context.

SEE ALSO
       ddi_dma_addr_bind_handle(9F),                 ddi_dma_alloc_handle(9F),
