    15 // DMA Framework - Client API definition.

    16 //

    17 // Inline implementations of functions which (originally) exposed DMA HAI

    18 // details that are now, after the header file split into dma_v2.h and

    19 // dma_hai.h, no longer meant to be visible to DMA clients. This file is only

    20 // included for DMA_APIV2 clients.

    21 //

    22 // This file is not meant to be a permanent one, and may eventually be removed

    23 // together with the deprecated functions it implements.
