      ASoC: ad193x: Split SPI and I2C code into different modules · 6c3d713e
      Lars-Peter Clausen 提交于
      There are a few known (minor) problems with having the support code for both I2C
      and SPI in the same module:
          * We need to be extra careful to make sure to not build the driver into the
            kernel if one of the subsystems is build as a module (Currently only I2C
            can be build as a module).
          * The module init path error handling is rather ugly. E.g. what should be
            done if either the SPI or the I2C driver fails to register? Most drivers
            that implement SPI and I2C in the same module currently fallback to
            undefined behavior in that case. Splitting the the driver into two
            modules, one for each bus, allows the registration of the other bus driver
            to continue without problems if one of them fails.
      
      This patch splits the AD193X driver into 3 modules. One core module that
      implements the device logic, but is independent of the bus method used. And one
      module for SPI and I2C each that registers the drivers and sets up the regmap
      struct for the bus.

      ASoC: Constify snd_soc_dai_ops structs · 85e7652d
      Lars-Peter Clausen 提交于
      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 =

      ASoC: ad193x: Setup regmap read and write flag masks for SPI · 30ab1e78
      Lars-Peter Clausen 提交于
      Currently register read-back for the ad193x is broken, because it expects bit 0
      of the upper byte to be set to indicate a read operation, while the regmap
      default for SPI is to use bit 7.
      
      This patch also addresses another oddity of the device. There are SPI and I2C
      versions of this codec. In both cases the registers are 8-bit wide and numbered
      from 0x0 to 0x10, but in the SPI case there is also a so called
      'global address' which is prefixed in-front of the register address. The global
      address mimics I2C behaviour and includes a static device address the and the
      read/write flag. This basically extends the register address to an 16-bit value
      numbered from 0x800 to 0x810. These are the register numbers which are
      currently used by the driver. This works, because I2C will ignore the upper
      8 bits of the register, but it is still a bit confusing, as there are no such
      register numbers in the I2C case.
      
      The approach taken by this patch is to number the registers from 0x00 to 0x10
      and encode the global address for SPI mode into the read and write flag masks.

      ASoC: Decouple DAPM from CODECs · ce6120cc
      Liam Girdwood 提交于
      Decoupling Dynamic Audio Power Management (DAPM) from codec devices is
      required when developing ASoC further. Such as for other ASoC components to
      have DAPM widgets or when extending DAPM to handle cross-device paths.
      
      This patch decouples DAPM related variables from struct snd_soc_codec and
      moves them to new struct snd_soc_dapm_context that is used to encapsulate
      DAPM context of a device. ASoC core and API of DAPM functions are modified
      to use DAPM context instead of codec.
      
      This patch does not change current functionality and a large part of changes
      come because of structure and internal API changes.
      
      Core implementation is from Liam Girdwood <lrg@slimlogic.co.uk> with some
      minor core changes, codecs and machine driver conversions from

      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: Add indirection for CODEC private data · b2c812e2
      Mark Brown 提交于
      One of the features of the multi CODEC work is that it embeds a struct
      device in the CODEC to provide diagnostics via a sysfs class rather than
      via the device tree, at which point it's much better to use the struct
      device private data rather than having two places to store it. Provide
      an accessor function to allow this change to be made more easily, and
      update all the CODEC drivers are updated.
      
      To ensure use of the accessor the private data structure member is
      renamed, meaning that if code developed with older an older core that
      still uses private_data is merged it will fail to build.
