      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

      OMAP: McBSP: implement functional clock switching via clock framework · d1358657
      Paul Walmsley 提交于
      Previously the OMAP McBSP ASoC driver implemented CLKS switching by
      using omap_ctrl_{read,write}l() directly.  This is against policy; the OMAP
      System Control Module functions are not intended to be exported to drivers.
      These symbols are no longer exported, so as a result, the OMAP McBSP ASoC
      driver does not build as a module.
      
      Resolve the CLKS clock changing portion of this problem by creating a
      clock parent changing function that lives in
      arch/arm/mach-omap2/mcbsp.c, and modify the ASoC driver to use it.
      Due to the unfortunate way that McBSP support is implemented in ASoC
      and the OMAP tree, this symbol must be exported for use by
      sound/soc/omap/omap-mcbsp.c.
      
      Going forward, the McBSP device driver should be moved from
      arch/arm/*omap* into drivers/ or sound/soc/* and the CPU DAI driver
      should be implemented as a platform_driver as many other ASoC CPU DAI
      drivers are.  These two steps should resolve many of the layering
      problems, which will rapidly reappear during a McBSP hwmod/PM runtime
      conversions.

      OMAP: McBSP: implement McBSP CLKR and FSR signal muxing via mach-omap2/mcbsp.c · cf4c87ab
      Paul Walmsley 提交于
      The OMAP ASoC McBSP code implemented CLKR and FSR signal muxing via
      direct System Control Module writes on OMAP2+.  This required the
      omap_ctrl_{read,write}l() functions to be exported, which is against
      policy: the only code that should call those functions directly is
      OMAP core code, not device drivers.  omap_ctrl_{read,write}*() are no
      longer exported, so the driver no longer builds as a module.
      
      Fix the pinmuxing part of the problem by removing calls to
      omap_ctrl_{read,write}l() from the OMAP ASoC McBSP code and
      implementing signal muxing functions in arch/arm/mach-omap2/mcbsp.c.
      Due to the unfortunate way that McBSP support is implemented in ASoC
      and the OMAP tree, these symbols must be exported for use by

      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: OMAP: Fix capture pointer handling for OMAP1510 to work correctly with recent ALSA PCM code · b5442a75
      Janusz Krzysztofik 提交于
      With recent (2.6.34) chnages in PCM handling, capture stopped working on my
      OMAP1510 based Amstrad Delta videophone.
      
      Using 2.6.34-rc2, I was able to correct the problem in 3 different ways:
      
      1. reverting commit 7b3a177b,
      2. enabling additional jiffies check with
      	echo 4 >/proc/asound/card0/pcm0c0/xrun_debug
      3. applying the patch below.
      
      Since I wasn't able to reproduce the problem on my i686 PC, I guess the
      problem is probably machine specific.
      
      The patch reuses the method for software emulation of missing hardware
      pointer, already implemented for playback on OMAP1510. It's possible that
      event if a hardware pointer is available for capture on this machine, its
      behaviour may be not compatible with what upper layer expects.
      
      If you think the problem may be more general and should be solved differently,
      on a higher level, I can try to work more on it if you give me a hint.
      
      If the patch gets accepted, I suggest it goes as a fix in the current release
      cycle.
      
      Created and tested against linux-2.6.34-rc2.

      include cleanup: Update gfp.h and slab.h includes to prepare for breaking... · 5a0e3ad6
      Tejun Heo 提交于
      include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
      
      percpu.h is included by sched.h and module.h and thus ends up being
      included when building most .c files.  percpu.h includes slab.h which
      in turn includes gfp.h making everything defined by the two files
      universally available and complicating inclusion dependencies.
      
      percpu.h -> slab.h dependency is about to be removed.  Prepare for
      this change by updating users of gfp and slab facilities include those
      headers directly instead of assuming availability.  As this conversion
      needs to touch large number of source files, the following script is
      used as the basis of conversion.
      
        http://userweb.kernel.org/~tj/misc/slabh-sweep.py
      
      The script does the followings.
      
      * Scan files for gfp and slab usages and update includes such that
        only the necessary includes are there.  ie. if only gfp is used,
        gfp.h, if slab is used, slab.h.
      
      * When the script inserts a new include, it looks at the include
        blocks and try to put the new include such that its order conforms
        to its surrounding.  It's put in the include block which contains
        core kernel includes, in the same order that the rest are ordered -
        alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
        doesn't seem to be any matching order.
      
      * If the script can't find a place to put a new include (mostly
        because the file doesn't have fitting include block), it prints out
        an error message indicating which .h file needs to be added to the
        file.
      
      The conversion was done in the following steps.
      
      1. The initial automatic conversion of all .c files updated slightly
         over 4000 files, deleting around 700 includes and adding ~480 gfp.h
         and ~3000 slab.h inclusions.  The script emitted errors for ~400
         files.
      
      2. Each error was manually checked.  Some didn't need the inclusion,
         some needed manual addition while adding it to implementation .h or
         embedding .c file was more appropriate for others.  This step added
         inclusions to around 150 files.
      
      3. The script was run again and the output was compared to the edits
         from #2 to make sure no file was left behind.
      
      4. Several build tests were done and a couple of problems were fixed.
         e.g. lib/decompress_*.c used malloc/free() wrappers around slab
         APIs requiring slab.h to be added manually.
      
      5. The script was run on all .h files but without automatically
         editing them as sprinkling gfp.h and slab.h inclusions around .h
         files could easily lead to inclusion dependency hell.  Most gfp.h
         inclusion directives were ignored as stuff from gfp.h was usually
         wildly available and often used in preprocessor macros.  Each
         slab.h inclusion directive was examined and added manually as
         necessary.
      
      6. percpu.h was updated not to include slab.h.
      
      7. Build test were done on the following configurations and failures
         were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my
         distributed build env didn't work with gcov compiles) and a few
         more options had to be turned off depending on archs to make things
         build (like ipr on powerpc/64 which failed due to missing writeq).
      
         * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
         * powerpc and powerpc64 SMP allmodconfig
         * sparc and sparc64 SMP allmodconfig
         * ia64 SMP allmodconfig
         * s390 SMP allmodconfig
         * alpha SMP allmodconfig
         * um on x86_64 SMP allmodconfig
      
      8. percpu.h modifications were reverted so that it could be applied as
         a separate patch and serve as bisection point.
      
      Given the fact that I had only a couple of failures from tests on step
      6, I'm fairly confident about the coverage of this conversion patch.
      If there is a breakage, it's likely to be something in one of the arch
      headers which should be easily discoverable easily on most builds of
      the specific arch.
