STRUCT SND_DMAENGINE(9)                      PCM API                      STRUCT SND_DMAENGINE(9)



NAME
       struct_snd_dmaengine_dai_dma_data - DAI DMA configuration data

SYNOPSIS
       struct snd_dmaengine_dai_dma_data {
         dma_addr_t addr;
         enum dma_slave_buswidth addr_width;
         u32 maxburst;
         unsigned int slave_id;
         void * filter_data;
         const char * chan_name;
         unsigned int fifo_size;
         unsigned int flags;
       };

MEMBERS
       addr
           Address of the DAI data source or destination register.

       addr_width
           Width of the DAI data source or destination register.

       maxburst
           Maximum number of words(note: words, as in units of the src_addr_width member, not
           bytes) that can be send to or received from the DAI in one burst.

       slave_id
           Slave requester id for the DMA channel.

       filter_data
           Custom DMA channel filter data, this will usually be used when requesting the DMA
           channel.

       chan_name
           Custom channel name to use when requesting DMA channel.

       fifo_size
           FIFO size of the DAI controller in bytes

       flags
           PCM_DAI flags, only SND_DMAENGINE_PCM_DAI_FLAG_PACK for now
