SND_HWPARAMS_TO_DMA_(9)                      PCM API                      SND_HWPARAMS_TO_DMA_(9)



NAME
       snd_hwparams_to_dma_slave_config - Convert hw_params to dma_slave_config

SYNOPSIS
       int snd_hwparams_to_dma_slave_config(const struct snd_pcm_substream * substream,
                                            const struct snd_pcm_hw_params * params,
                                            struct dma_slave_config * slave_config);

ARGUMENTS
       substream
           PCM substream

       params
           hw_params

       slave_config
           DMA slave config

DESCRIPTION
       This function can be used to initialize a dma_slave_config from a substream and hw_params
       in a dmaengine based PCM driver implementation.
