      ARM: omap: fix broken twl-core dependencies and ifdefs · 6252547b
      Russell King 提交于
      In commit aeb5032b, a dependency on IRQ_DOMAIN was added, which causes
      regressions on previously working setups: a previously working non-DT
      kernel configuration now loses its PMIC support.  The lack of PMIC
      support in turn causes the loss of other functionality the kernel had.
      
      This dependency was added because the driver now registers its
      interrupts with the IRQ domain code, presumably to prevent a build error.
      
      The result is that OMAP3 oopses in the vp.c code (fixed by a previous
      commit) due to the lack of PMIC support.
      
      However, even with IRQ_DOMAIN enabled, the driver oopses:
      
      Unable to handle kernel NULL pointer dereference at virtual address 00000000
      pgd = c0004000

      This happens because we try to register an IRQ domain with a NULL ops
      structure, and the first thing irq_domain_add() does is try to
      dereference this ops structure.
      
      So, fix the problem by getting rid of the incorrect OF_IRQ ifdef and
      wrapping the IRQ domain bits of the driver with an IRQ_DOMAIN ifdef
      instead.

      mfd: twl6040: Add initial support · f19b2823
      Misael Lopez Cruz 提交于
      TWL6040 IC provides analog high-end audio codec functions for
      handset applications. It contains several audio analog inputs
      and outputs as well as vibrator support. It's connected to the
      host processor via PDM interface for audio data communication.
      The audio modules are controlled by internal registers that
      can be accessed by I2C and PDM interface.
      
      TWL6040 MFD will be registered as a child of TWL-CORE, and will
      have two children of its own: twl6040-codec and twl6040-vibra.
      
      This driver is based on TWL4030 and WM8350 MFD drivers.

      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().
