NAME
       snd_dmaengine_pcm_prepare_slave_config - Generic prepare_slave_config callback

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

ARGUMENTS
       substream
           PCM substream

       params
           hw_params

       slave_config
           DMA slave config to prepare

DESCRIPTION
       This function can be used as a generic prepare_slave_config callback for platforms which
       make use of the snd_dmaengine_dai_dma_data struct for their DAI DMA data. Internally the
       function will first call snd_hwparams_to_dma_slave_config to fill in the slave config
       based on the hw_params, followed by snd_dmaengine_set_config_from_dai_data to fill in the
       remaining fields based on the DAI DMA data.
