      ASoC: Make rtd->codec optional · 93c3ce76
      Lars-Peter Clausen authored
      There are some place in the ASoC core that expect rtd->codec to be non NULL
      (mainly CODEC specific sysfs files). With componentization going forward
      rtd->codec might be NULL in some cases. This patch prepares the core for this by
      not registering CODEC specific sysfs files if rtd->codec is NULL. sysfs file
      removal does not need to be conditionalized as it handles the removal of
      non-existing files just fine.

      ASoC: Consolidate platform and CODEC probe/remove · f1d45cc3
      Lars-Peter Clausen authored
      The platform and CODEC probe and remove code is now largely identical. This
      patch consolidates it at the component level.
      
      The resulting code is slightly larger due to all the boiler plate code setting
      up the indirection for the table based control and DAPM registration.  Once all
      drivers have been update to no longer use the snd_soc_codec_driver and
      snd_soc_platform_driver specific fields for this the indirection can be removed
      again.
      
      This patch contains two noteworthy hacks that are only meant to be temporary to
      be able to update drivers and the core in separate incremental patches.
      
      The first hack is related to that some DPCM platforms expect that the DAPM
      widgets for the DAIs of a snd_soc_component are created in the DAPM context of
      the snd_soc_platform that has the same parent device. For handling this the
      steal_sibling_dai_widgets attribute is introduced. It gets set for
      snd_soc_platforms that register DAPM elements. When creating the DAI widgets for
      a component this flag is checked and if it is found on one of the siblings the
      component will not create any DAI widgets in its own DAPM context. If the
      attribute is set on a platform it will look for siblings components and create
      DAI widgets for them in its own context. The fix for this will be to update
      the offending drivers to only register a single component rather than two.
      
      The second hack deals with the fact that the ASoC card suspend and resume code
      still needs a list of CODECs that have been registered for the card. To handle
      this the generic probe and remove path have a check to see if the component is
      CODEC and if yes add/remove it to the card's CODEC list. While it is possible to
      clean up the suspend/resume code to not need the CODEC list anymore this is a
      bit of a chicken and egg problem since it will become easier to clean up the
      suspend/resume code once there is a unified component layer.

      ASoC: Move debugfs registration to the component level · 81c7cfd1
      Lars-Peter Clausen authored
      The debugfs registration is mostly identical between platforms and CODECs. This
      patches consolidates the two implementations at the component level.
      
      Unfortunately there are still a couple of CODEC specific debugfs files that are
      related to legacy ASoC IO that need to be registered. For this a new callback is
      added to the component struct that will be initialized when a CODEC is
      registered and will be used to register the CODEC specific files. Once there are
      no drivers left using legacy IO this can be removed again.
