      ASoC: kirkwood: change the compatible string of the kirkwood-i2s driver · d098b2f0
      Thomas Petazzoni authored
      The compatible string of the kirkwood-i2s driver was chosen as
      "marvell,mvebu-audio". Using such a compatible string is not a good
      idea, since "mvebu" is the name of a large family of SOCs, in which
      new, unknown SOCs will be coming in the future. It is therefore
      impossible to know what will be evolutions of this hardware block in
      the next generations of the SOCs. For this reason, the recommandation
      for compatible strings of on-SOCs devices has always been to use the
      name of the oldest SOC that has the hardware block. New SOCs that have
      an exactly compatible hardware block can reference it using the same
      compatible string. See [1], [2] and [3] for various cases were this
      suggestion was made, including from Rob Herring, a Device Tree binding
      maintainer.
      
      As an example, there are already small differences between current
      generations:
      
       * On Kirkwood, only one interrupt is used for audio.
       * On Dove, two interrupts are used, one for audio data and one for
         error reporting.
      
      In the near future, I'll be adding audio support to Armada 370, which
      allows has the same hardware block (but maybe with minor variants).
      
      Therefore, this patch changes the driver to accept
      "marvell,kirkwood-audio" and "marvell,dove-audio" as compatible
      strings instead of the too-generic "marvell,mvebu-audio". The reason
      for the two different compatible strings is the difference in the
      number of interrupts used by the two SOCs for audio.
      
      This Device Tree binding has never been part of a Linux kernel stable
      release so far, so it can be changed now without breaking backward
      compatibility.

      ASoC: Fix build error in sound/soc/kirkwood/kirkwood-i2s.c · d4d9820b
      Axel Lin authored
      Since commit db33f4de "ARM: Orion: Remove address map info from all platform data structures",
      the dram is removed from struct kirkwood_asoc_platform_data.
      
      This patch fixes below build error:

      ASoC: Constify snd_soc_dai_ops structs · 85e7652d
      Lars-Peter Clausen authored
      Commit 1ee46ebd("ASoC: Make the DAI ops constant in the DAI structure")
      introduced the possibility to have constant DAI ops structures, yet this is
      barley used in both existing drivers and also new drivers being submitted,
      although none of them modifies its DAI ops structure. The later is not
      surprising since existing drivers are often used as templates for new drivers.
      So this patch just constifies all existing snd_soc_dai_ops structs to eliminate
      the issue altogether.
      
      The patch was generated with the following coccinelle semantic patch:
      // <smpl>
      @@
      identifier ops;
      @@
      -struct snd_soc_dai_ops ops =
      +const struct snd_soc_dai_ops ops =
      { ... };
      // </smpl>

      ASoC: multi-component - ASoC Multi-Component Support · f0fba2ad
      Liam Girdwood authored
      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().
