ASoC: dai_dma: remove slave_id field

2021-12-17T05:53:56+00:00

This field is no longer set from any driver now, so remove the
last references as well.

ASoC: dmaengine_pcm: add peripheral configuration

2021-02-05T17:16:41+00:00

The commit e7bbb7acabf4 ("dmaengine: add peripheral configuration")
adds peripheral configuration for dma_slave_config.

This configuration is useful for some audio peripherals, for
example, the peripheral supports multi fifos, we can
let the DMA know which fifos are selected. So also add
this configuration for snd_dmaengine_dai_dma_data.

ASoC: dmaengine_pcm: export soc_component_to_pcm

2020-06-12T13:18:02+00:00

In DPCM case, Front-End needs to get the dma chan which has
been requested by Back-End and reuse it.

ASoC: pcm_dmaengine: Extract snd_dmaengine_pcm_refine_runtime_hwparams

2019-10-01T11:18:25+00:00

When set the runtime hardware parameters, we may need to query
the capability of DMA to complete the parameters.

This patch is to Extract this operation from
dmaengine_pcm_set_runtime_hwparams function to a separate function
snd_dmaengine_pcm_refine_runtime_hwparams, that other components
which need this feature can call this function.

ASoC: dmaengine: Remove unused SND_DMAENGINE_PCM_FLAG_CUSTOM_CHANNEL_NAME flag

2019-02-14T16:17:35+00:00

There is now no users of this flag so remove it together with
related code.  The chan_name field of snd_dmaengine_dai_dma_data
data structure is not removed as it is still in use by the PXA
platform.

ASoC: dmaengine_pcm: add processing support

2018-02-26T11:11:20+00:00

Allow dmaengine client to optionally register a processing callback.
This callback is intended to apply processing
on samples in buffer copied from/to user space, before/after DMA transfer.

ASoC: Revert "Drop SND_DMAENGINE_PCM_FLAG_CUSTOM_CHANNEL_NAME flag"

2017-01-23T18:16:33+00:00

This reverts commit c6644119a3f80ea644bde10009d5e1013b5aff29 and
restores the ability to specify DMA channel names per DAI dma_data.
Unfortunately the functionality removed in the patch being reverted
cannot be entirely replaced by specifying DMA channel names in struct
snd_dmaengine_pcm_config as that does not cover devices with more than
2 DMA channels.

Together with patch "ASoC: Revert "samsung: Remove unneeded
initialization of chan_name"" this fixes broken sound on the s3c24xx
SoC platforms.
