      ASoC: Flush Samsung DMA on free · 2ca95769
      Mark Brown 提交于
      Ever since it was written the Samsung DMA driver has had a TODO in the
      hw_free() function wondering if we need to flush the DMA buffers. Up until
      now the answer has been no but with the recent improvements Boojin has
      done to the DMA infrastructure for the Samsung port the answer has changed
      to yes for at least S3C6410 systems.
      
      If we don't then when we next prepare() the channel the API will get
      confused trying to run callbacks on the transfers hanging around from the
      previous time the stream was open and oops.

      ASoC: multi-component - ASoC Multi-Component Support · f0fba2ad
      Liam Girdwood 提交于
      This patch extends the ASoC API to allow sound cards to have more than one
      CODEC and more than one platform DMA controller. This is achieved by dividing
      some current ASoC structures that contain both driver data and device data into
      structures that only either contain device data or driver data. i.e.
      
       struct snd_soc_codec    --->  struct snd_soc_codec (device data)
                                +->  struct snd_soc_codec_driver (driver data)
      
       struct snd_soc_platform --->  struct snd_soc_platform (device data)
                                +->  struct snd_soc_platform_driver (driver data)
      
       struct snd_soc_dai      --->  struct snd_soc_dai (device data)
                                +->  struct snd_soc_dai_driver (driver data)
      
       struct snd_soc_device   --->  deleted
      
      This now allows ASoC to be more tightly aligned with the Linux driver model and
      also means that every ASoC codec, platform and (platform) DAI is a kernel
      device. ASoC component private data is now stored as device private data.
      
      The ASoC sound card struct snd_soc_card has also been updated to store lists
      of it's components rather than a pointer to a codec and platform. The PCM
      runtime struct soc_pcm_runtime now has pointers to all its components.
      
      This patch adds DAPM support for ASoC multi-component and removes struct
      snd_soc_socdev from DAPM core. All DAPM calls are now made on a card, codec
      or runtime PCM level basis rather than using snd_soc_socdev.
      
      Other notable multi-component changes:-
      
       * Stream operations now de-reference less structures.
       * close_delayed work() now runs on a DAI basis rather than looping all DAIs
         in a card.
       * PM suspend()/resume() operations can now handle N CODECs and Platforms
         per sound card.
       * Added soc_bind_dai_link() to bind the component devices to the sound card.
       * Added soc_dai_link_probe() and soc_dai_link_remove() to probe and remove
         DAI link components.
       * sysfs entries can now be registered per component per card.
       * snd_soc_new_pcms() functionailty rolled into dai_link_probe().
       * snd_soc_register_codec() now does all the codec list and mutex init.
      
      This patch changes the probe() and remove() of the CODEC drivers as follows:-
      
       o Make CODEC driver a platform driver
       o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core.
       o Removed all static codec pointers (drivers now support > 1 codec dev)
       o snd_soc_register_pcms() now done by core.
       o snd_soc_register_dai() folded into snd_soc_register_codec().

      ASoC: S3C platform: Fix s3c2410_dma_started() called at improper time · faf907c7
      Shine Liu 提交于
      s3c24xx dma has the auto reload feature, when the the trnasfer is done,
      CURR_TC(DSTAT[19:0], current value of transfer count) reaches 0, and DMA
      ACK becomes 1, and then, TC(DCON[19:0]) will be loaded into CURR_TC. So
      the transmission is repeated.
      
      IRQ is issued while auto reload occurs. We change the DISRC and
      DCON[19:0] in the ISR, but at this time, the auto reload has been
      performed already. The first block is being re-transmitted by the DMA.
      
      So we need rewrite the DISRC and DCON[19:0] for the next block
      immediatly after the this block has been started to be transported.
      
      The function s3c2410_dma_started() is for this perpose, which is called
      in the form of "s3c2410_dma_ctrl(prtd->params->channel,
      S3C2410_DMAOP_STARTED);" in s3c24xx_pcm_trigger().
      
      But it is not correct. DMA transmission won't start until DMA REQ signal
      arrived, it is the time s3c24xx_snd_txctrl(1) or s3c24xx_snd_rxctrl(1)
      is called in s3c24xx_i2s_trigger().
      
      In the current framework, s3c24xx_pcm_trigger() is always called before
      s3c24xx_pcm_trigger(). So the s3c2410_dma_started() should be called in
      s3c24xx_pcm_trigger() after s3c24xx_snd_txctrl(1) or
      s3c24xx_snd_rxctrl(1) is called in this function.
      
      However, s3c2410_dma_started() is dma related, to call this function we
      should provide the channel number, which is given by
      substream->runtime->private_data->params->channel. The private_data
      points to a struct s3c24xx_runtime_data object, which is define in
      s3c24xx_pcm.c, so s3c2410_dma_started() can't be called in s3c24xx_i2s.c
      
      Fix this by moving the call to signal the DMA started to the DAI
      drivers.
