      ASoC: remove trigger delay in Freescale MPC8610 sound driver · a4d11fe5
      Timur Tabi authored
      Remove the delay from the trigger function in the Freescale MPC8610 sound
      driver when capture is started.  This delay was used to ensure that the DMA
      controller was active when ALSA call the .pointer function to request a
      DMA transfer status.  A better approach is for the .pointer function to detect
      that DMA has not started, and return zero instead.  This change eliminates
      the need for the delay.
      
      Also add some related code to check for a DMA programming error, and report
      XRUN if it occurs.

      ASoC: Register platform DAIs · 3f4b783c
      Mark Brown authored
      Register all platform DAIs with the core.  In line with current behaviour
      this is done at module probe time rather than when the devices are probed
      (since currently that only happens as the entire ASoC card is registered
      except for those drivers that currently implement some kind of hotplug).
      Since the core currently ignores DAI registration this has no practical
      effect.

      ASoC: Merge snd_soc_ops into snd_soc_dai_ops · dee89c4d
      Mark Brown authored
      Liam Girdwood's ASoC v2 work avoids having two different ops structures
      for DAIs by merging the members of struct snd_soc_ops into struct
      snd_soc_dai_ops, allowing per DAI configuration for everything.
      Backport this change.
      
      This paves the way for future work allowing any combination of DAIs to
      be connected rather than having fixed purpose CODEC and CPU DAIs and
      only allowing CODEC<->CPU interconnections.

      ALSA: asoc: restrict sample rate and size in Freescale MPC8610 sound drivers · be41e941
      Timur Tabi authored
      The Freescale MPC8610 SSI device has the option of using one clock for both
      transmit and receive (synchronous mode), or independent clocks (asynchronous).
      The SSI driver, however, programs the SSI into synchronous mode and then
      tries to program the clock registers independently.  The result is that the wrong
      sample size is usually generated during recording.
      
      This patch fixes the discrepancy by restricting the sample rate and sample size
      of the playback and capture streams.  The SSI driver remembers which stream
      is opened first.  When a second stream is opened, that stream is constrained
      to the same sample rate and size as the first stream.
      
      A future version of this driver will lift the sample size restriction.
      Supporting independent sample rates is more difficult, because only certain
      codecs provide dual independent clocks.
