Config API

- conf: implement snd_config_add_before() and snd_config_add_after()

- ucm: change the If block parsing

  - evaluate always If before the other blocks

- ucm: add If condition block

  The syntax is simple:
  
  If./any-if-identificator/ {
    Condition {
      Type /type_here/
      /optional defines/
    }
    True {
      /block used when condition is evaluated as true/
    }
    False {
      /block used when condition is evaluated as false/
    }
  }
  
  The Type "ControlExists" is implemented:
  
  Condition {
    Type ControlExists
    Device "hw:${CardId}"
    Control "iface=CARD,name='Headphone Jack'"
  }
  

Control API

- control_shm: add missing socket close to the error path (coverity)

- control_shm: remove duplicate code (coverity)

Mixer API

- mixer: simple - add snd_mixer_selem_id_parse() from amixer

PCM API

- pcm: the maximal rate is 768000Hz, fix the remain code

- pcm: fix the period_size for direct plugins (dmix, dsnoop, dshare)

  BugLink: https://github.com/alsa-project/alsa-lib/issues/8

- pcm: Fix the wrong PCM object passed for locking/unlocking

  Most of PCM API functions have snd_pcm_lock()/unlock() wraps for the
  actual calls of ops, and some plugins try to unlock/relock internally
  for the given PCM object.  This, unfortunately, causes a problem in
  some configurations and leads to the unexpected behavior or deadlock.
  
  The main problem is that we call snd_pcm_lock() with the given PCM
  object, while calling the ops with pcm->op_arg or pcm->fast_op_arg as
  the slave PCM object.  Meanwhile the plugin code assumes that the
  passed PCM object is already locked, and calls snd_pcm_unlock().
  This bug doesn't hit always because in most cases pcm->op_arg and
  fast_op_arg are identical with pcm itself.  But in some configurations
  they have different values, so the problem surfaces.
  
  This patch is an attempt to resolve these inconsistencies.  It
  replaces most of snd_pcm_lock()/unlock() calls with either pcm->op_arg
  or pcm->fast_op_arg, depending on the call pattern, so that the plugin
  code can safely run snd_pcm_unlock() to the given PCM object.

- pcm: chmap: Fix memory leak at snd_pcm_set_chmap()

  snd_pcm_set_chmap() leaks the memory returned from snd_pcm_get_chmap()
  without releasing.  Add the missing free() call as well as a slight
  code refactoring.
  
  Reported-by: Conrad Jones
  BugLink: https://github.com/alsa-project/alsa-lib/pull/11
  Fixes: d20e24e5d161 ("chmap: Always succeed setting the map to what it already is")

- pcm: dshare: allow missing bindings

  allow opening the device and start the audio clock without blocking
  any channel
  
  this is required if the audio clock has to be available all the time,
  even when application is not streaming audio data
  

- pcm: return -ENOSYS when ops or fast_ops callback is NULL

  function is allowed to continue until it checks for error variable, as to
  not conflict with original implementation flow
  
  for simple functions involving only one line, return error immediately in
  case callback is NULL
  

- pcm_file: improve error checking in write_wav_header function

  previously errno would be returned even for cases where it may have
  not been populated, for example one of the write functions failing,
  or writing only partial buffer,
  
  now progress through write operations separately and report errno when
  appropriate
  

- pcm_file: in case of failed write clear file buffer variables

  previously, in case of failed write to output file, error is returned
  from snd_pcm_writei/read APIs, user could run pcm_drain as fallback and
  encounter an assert, since drain would try to write remaining file
  buffer to a file
  
  if failed to write to output file in first place, it makes sense to clear
  current internal pmc_file file buffer variables
  

- pcm_file: use EIO instead of EPIPE when failing to write output file

  EPIPE is defined as XRUN which is not entirely correct in this condition
  
  failing to write to a file in pcm_file plugin can not be simply recovered
  by a retry as user of the api might be led to believe when receiving EPIPE
  
  use EIO instead to indicate a different kid of error that may not be
  recoverable by retry
  

- pcm_file: return errno in case of a failed write operation

  allows correct error code propagation for snd_pcm_file_write_bytes caller
  

- pcm_file: remove double line

  snd_pcm_file_add_frames called two times by mistake, introduced in
  2a800c0c4f259043c9217a4aa6a57afaf9f77477
  

- pcm_file: report write output file error to api user

  when writing to output file fails, api user is notified and can handle
  recovery
  

- pcm_file: do not disrupt playback on output file write fail

  previously playback could be interrupted by snd_pcm_file_add_frames:
      assert(file->wbuf_used_bytes < file->wbuf_size_bytes)
  
  in case snd_pcm_file_write_bytes fails to write full amount of bytes
  to file, variable wbuf_used_bytes would not be fully decremented by
  requested amount of bytes function was called with
  
  for the assert to trigger, multiple write fails need to happen, so
  that wbuf_used_bytes overflows wbuf_size_bytes,
  
  this patch will allow application to report error code to api user
  who might have an idea how to recover, before assert is triggered,
  also reporting error along with the print out message might give user
  a better idea of what is going on, where previously reason for
  mentioned assert was not immediately clear
  

- pcm: rate: Avoid pointer arithmetic on `void *`

  The pointer operand to the binary `+` operator must be to a complete
  object type.
  

- pcm: direct: Remove unused empty struct

- pcm: Make sure parameter qualifiers match between declaration and definition

- pcm: hw: Don't return in a void function

  A return statement with an expression in a function returning void is
  a constraint violation.
  

- Use __func__ instead of __FUNCTION__

  They are equivalent, but __func__ is in C99. __FUNCTION__ exists only
  for backwards compatibility with old gcc versions.
  

- pcm_file: another locking fix (coverity)

- pcm_file: coverity fixes (including double locking)

- pcm_hw: close file descriptor in the error path in snd_pcm_hw_open() (coverity)

- pcm_file: call pclose() correctly for popen() (coverity)

- pcm: fix memory leak in _snd_pcm_parse_config_chmaps() (coverity)

- pcm: file: add infile read support for mmap mode

  mmap_begin callback is used to copy data from input file to mmaped
  buffer
  
  guard for corner use of api (multiple mmap_begin calls by user) is
  introduced to check if next continuous buffer was already overwritten
  
  buffer is overwritten with input file data only in case of stream capture
  

- pcm: add mmap_begin callback to snd_pcm_fast_ops_t api

  main motivation for adding the callback is to use it to enable operation
  on mmaped buffer before user access for pcm_file plugin
  
  support for MMAP read access with masking by data from input file is not
  implemented for pcm_file plugin, by adding this callback implementing
  such feature can be done by rewriting next continuous portion of buffer
  on each mmap_begin call
  
  plugins like softvol use pcm_plugin interface and overwrite the buffer by
  looping around it in avail_update callback, this patch hopes to simplify
  the task by adding new api callback, removing the need for rewriting
  pcm_file (to use pcm_plugin callbacks) and careful checking when looping
  around whole mmaped buffer
  

- pcm: file: add missing unlock on early return

- pcm: file: use snd_pcm_file_areas_read_infile for readi

  use previously introduced helper function, this commit unifies behavior
  of readi and readn
  
  corner case behavior of readi is changed by this commit, previously,
  in case 0 bytes were red from file (EOF), frames = 0 was returned,
  signaling api user as if no data was red from slave, after the patch,
  amount of frames red from slave with data red from slave stored in buffer
  is returned when EOF is reached
  

- pcm: file: add support for infile reading in non interleaved mode

  add helper function to copy input file data to buffer mapped by areas,
  in case of an error, do not fill the areas, allowing device read buffer
  to be provided to api caller
  
  previously unused rbuf variable is reused for this purpose
  

- pcm: dsnoop: Added "hw_ptr_alignment" option in configuration for slave pointer alignment

  This change adapt the fix commit 6b058fda9dce
  ("pcm: dmix: Add option to allow alignment of slave pointers")
  for dsnoop plugin
  
  Issue is that snd_pcm_wait() goes back to waiting because the hw_ptr
  is not period aligned. Therefore snd_pcm_wait() will block for a longer
  time as required.
  
  With these rcar driver changes the exact position of the dma is returned.
  During snd_pcm_start they read hw_ptr as reference, and this hw_ptr
  is now not period aligned, and is a little ahead over the period while it
  is read. Therefore when the avail is calculated during snd_pcm_wait(),
  it is missing the avail_min by a few frames.
  
  An additional option hw_ptr_alignment is provided to dsnoop configuration,
  to allow the user to configure the slave application and hw pointer
  alignment at startup
  

- pcm: dshare: Added "hw_ptr_alignment" option in configuration for alignment of slave pointers

  This change adapt the fix commit 6b058fda9dce
  ("pcm: dmix: Add option to allow alignment of slave pointers")
  for dshare plugin
  
  Issue is that snd_pcm_wait() goes back to waiting because the hw_ptr
  is not period aligned. Therefore snd_pcm_wait() will block for a longer
  time as required.
  
  With these rcar driver changes the exact position of the dma is returned.
  During snd_pcm_start they read hw_ptr as reference, and this hw_ptr
  is now not period aligned, and is a little ahead over the period while it
  is read. Therefore when the avail is calculated during snd_pcm_wait(),
  it is missing the avail_min by a few frames.
  
  An additional option hw_ptr_alignment is provided to dshare configuration,
  to allow the user to configure the slave application and hw pointer
  alignment at startup
  

- pcm: direct: Add generic hw_ptr_alignment function for dmix, dshare and dsnoop

  Move the code snd_pcm_direct_reset_slave_ptr() from pcm_dmix.c
  to pcm_direct.c and its header so that the helper function can be
  re-used by other direct-pcm plugins.
  There is no change in the behavior or the functionality.
  

PCM Plugin API

- pcm: the maximal rate is 768000Hz, fix the remain code

RawMidi API

- rawmidi_hw: add sanity check for the invalid stream arguments (coverity)

- rawmidi: use snd_dlobj_cache_get2() in rawmidi open (coverity)

  Use proper reference counting for the dynamic symbol.
  

Topology API

- create separated libatopology library with the topology routines

- topology: Fix variable overflow in split_format

  The 1 which was 32-bit long, when left-shifted by more than 31 caused
  an overflow, which resulted in some of the formats being not supported.
  

- topology: add support to parse private data for pcm

  We have private data section in struct snd_soc_tplg_pcm, but alsatplg
  doesn't support handling it yet, here add handling in tplg_parse_pcm()
  to enable it.
  

- topology: next round of coverity fixes

- topology: various coverity fixes

Use Case Manager API

- ucm: add possibility to keep order of childs for If blocks

  Because of the nature of the structured parser, it is not guaranteed
  that the order of the parsed tree is equal to the lines in the source.
  
  Add possibility to insert the If results before or after the selected
  identifier like:
  
  SectionDevice."Speaker" {
    ...
  }
  
  If.1 {
          Condition { ... }
          Before.SectionDevice "Speaker"
          True { ... }
  }
  If.2 {
          Condition { ... }
          After.SectionDevice "Speaker"
          True { ... }
  }
  
  If the "After" or "Before" identifiers are not found, the result is added
  after the last entry in the block.
  

- ucm: change the If block parsing

  - evaluate always If before the other blocks

- ucm: docs: Add MinBufferLevel value

  Allows ucm to override minimum buffer level for platforms that
  incorrectly report their buffer level.
  

- ucm: docs: Add EDID File value

  Add a sys path to the EDID file for the corresponding HDMI device so
  userspace can use if needed
  

- use-case header file: add more references to correct ASCII ID parsers for CTL/mixer IDs

- ucm: add snd_use_case_parse_selem_id()

  and add strict ucm_id checks to snd_use_case_parse_ctl_elem_id()
  

- ucm: add If.Condition.RegexMatch

  If.1 {
          Condition {
                  Type RegexMatch
                  String "something to match"
                  Regex ".*(thing)"
          }
          ...
  }
  

- ucm: add ${CardComponents} substitution to the value string processing

- ucm: evaluate nested If blocks also in True/False blocks

- ucm: add If.Condition.String to match strings and substrings

  Case insensitive string match:
  
  If.1 {
          Condition {
                  Type String
                  String1 "aa"
                  String2 "bb"
          }
          True {
                  ...
          }
  }
  
  Substring is present (case sensitive):
  
  If.1 {
          Condition {
                  Type String
                  Haystack "White Horse"
                  Needle "Horse"
          }
          True {
                  ...
          }
  }
  

- ucm: add snd_use_case_parse_ctl_elem_id()

- ucm: add PlaybackCTL and CaptureCTL default values when they are not set

- ucm: small cosmetic uc_error change in execute_sequence()

- ucm: add If condition block

  The syntax is simple:
  
  If./any-if-identificator/ {
    Condition {
      Type /type_here/
      /optional defines/
    }
    True {
      /block used when condition is evaluated as true/
    }
    False {
      /block used when condition is evaluated as false/
    }
  }
  
  The Type "ControlExists" is implemented:
  
  Condition {
    Type ControlExists
    Device "hw:${CardId}"
    Control "iface=CARD,name='Headphone Jack'"
  }
  

- ucm: do not cache all control devices in get_card_long_name()

- ucm: parser - use less memory for integer/real values in parse_value()

- ucm: save the whole ctl info to the ctl_list structure

- ucm: add the run-time variable substitution

  Those two variables are supported:
  
    ${ConfName}      - configuration file name
    ${CardId}        - card identification string (like PCH)
    ${CardName}      - card name (driver)
    ${CardLongName}  - card long name (driver)
    ${env:ENV_NAME}  - returns the environment variable ENV_NAME
  

- ucm: fix memory leaks for cdev, bin-file and tlv elements

- ucm: do not report failure when long name configuration does not exist

- ucm: add support for multiple control devices, more aggresive caching

- ucm: extend snd_use_case_mgr_open() to address the sound card directly

  Some clients like pulseaudio wants to access the multiple instances
  of sound cards. This patch adds prefixes like "hw:" to the card_name
  argument to handle this. The card index (value) or card identification
  (string) can be used for this prefix.
  
  Also the prefix "strict:" was added to avoid the driver name and
  driver long name matching. It might be useable for use case
  configurations which are not bound to the one sound card.
  

- ucm: switch to ucm2 directory and v2 format, keep backward compatibility

- conf: improve the include paths code

  - various cleanups (more straight code and allocations)
  - do not add the base config path /usr/share/alsa to the
    explicit include list of directories
    (it's not wanted for ucm configs)
  

- ucm: parse_verb_file() - remove folder_name variable and extra logic

  The member uc_mgr->conf_file_name already contains the used directory
  name.
  

- ucm: fix uc_mgr_scan_master_configs() - skip correctly component directories

- ucm: cosmetic fix in get_card_long_name()

- ucm: another coverity fix in uc_mgr_config_load() - ucm: coverity fixes

Core

- Release v1.2.1

Audio Transfer utility

- axfer: handle -ETIMEDOUT before non-block I/O operation

  When running for IRQ-based scheduling model, transmission backend is
  expected to queue PCM event in different context from the main thread.
  When queueing no events during time equivalent to one period of PCM
  buffer, the backend has problems.
  
  This commit outputs report it for non-blocking operation for IRQ-based
  scheduling model. The timeout is equivalent to all frames in buffer,
  instead of period for safe.
  

- axfer: code refactoring for a helper function to wait for avail buffer space

  This commit applies code refactoring for waiting PCM event queued
  per period of PCM buffer in copying operation for IRQ-based scheduling
  model.
  

- axfer: handle -ETIMEDOUT before handle mmap I/O operation

  When running for IRQ-based scheduling model, transmission backend is
  expected to queue PCM event in different context from the main thread.
  When queueing no events during time equivalent to one period of PCM
  buffer, the backend has problems.
  
  This commit outputs report it for mmap operation for IRQ-based

  instead of period for safe.
  

- axfer: return ETIMEDOUT when no event occurs after waiter expiration

  Although the waiter abstraction handles timeout as success, it should
  report for callers to know timeout.
  
  This commit takes the waiter to return -ETIMEDOUT when timeout expires.
  

- axfer: fix to return error code when a call of select(2) fails

  A call of select(2) returns negative code and report errors via errno
  local variable, howver current waiter implementation for select(2)
  returns the negative code instead of errno.
  
  This commit fixes it.
  

- axfer: return the number of file descriptors for I/O events from select(2) waiter

  A call of select(2) returns error code at failure, the number of file
  descriptors available I/O at success. Current implementation of
  waiter abstraction for select(2) returns 0 at success and callers
  can't get the number.
  
  This commit fixes it.
  

- axfer: test: fix invalid comparison of 64 bit storage in ILP32 data type

  In system V ABIs with ILP32 data model, bit shift for '1ul' can brings
  undefined behaviour when the calculation result is over 32 bit width.
  
  This commit fixes the bug.

alsa-plugins

Core

- Release v1.2.1

PulseAudio -> ALSA plugin

- pulse: Add DEVICE parameter

  Basically this patch adds the DEVICE parameter to pulse PCM and
  control plugins, so that users may pass the specific pulse device
  for multiple opens.  Along with the addition of the DEVICE parameter
  in the config definition, the plugin code is slightly modified for
  allowing to receive the empty strings that are treated as the
  "default" mode (= NULL).

- sof-hda-dsp: Fix the Hdmi config for the Lenovo Carbon X1 (7th gen)

- sof-hda-dsp: improve the Hdmi use case comment

- sof-hda-dsp: fix the capture device names (use sofhdadsp)

- SOF/HDA/SKL UCM: rename from sof-skl_hda_card to sof-hda-dsp

  Follow the kernel change and rename everything to more clear
  sof-hda-dsp.
  

- sof-skl_hda: change to use common HDMI codec driver

  Modify UCM sequences to use user-space interface of the common
  HDMI codec driver. Use of hdac-hdmi driver is no longer supported
  by this UCM file.
  
  To use this UCM file, kernel must be compiled with
  SND_SOC_SOF_HDA_COMMON_HDMI_CODEC
  

- sof-skl_hda: move hdmi as separate use case

  Move hdmi definitions as separate use case and conf file. This will
  enable Pulseaudio to create separate profile for hdmi and make routing
  much more fluent than with single profile.
  

- sof-skl_hda: add PlaybackVolume and CaptureVolume definitions

  PlaybackVolume and CaptureVolume are not defined currently and these are
  needed in the future for example with Pulseaudio to enable hardware
  volume control.
  

- sof-skl_hda: add device definition to speaker disable sequence

  For example Pulseaudio is not able to run the disable sequence
  if the device is not defined. So add the definition.
  

- sof-skl_hda: remove volume setting in enable/disable sequences

  If the volume setting is defined in enable sequence you will

- ucm: bytcr/PlatformEnableSeq.conf update some comments

  Commit f91cc3c7d6b7 ("Update chtrt5645 ucm variants to use
  bytcr/PlatformEnableSeq.conf component") updated the
  following 2 comments:
  
   # codec0_out settings (used if SSP2 is connected to aif1)
   # modem_out settings (used if SSP0 is connected to aif2)
  
  Specifically it added the " to aif1" resp. " to aif2" part of the comments.
  
  This is not correct, AIF1 / AIF2 are something which is present on
  Realtek codecs only, and either one can be used indepedent of
  SSP0 or SSP2 being used (the comments in the chtrt5645 UCM profile
  before this change were wrong / outdated).
  
  Besides there not being any relationship between SSP0 or SSP2 being
  used, bytcr/PlatformEnableSeq.conf is also used with other codecs,
  e.g. the ESS8316 codec where this is not applicable at all.
  
  Therefor this commit removes the " to aif?" part of the comments again
  to avoid confusing people reading this in the future.

  used and if in1 or in2 is used for the internal mic (the headset mic will
  be on the other input).

  a Makefile.
  
  Some lines like
      cset "name='Stereo1 ADC1 Mux' 1"
  and
      cset "name='I2S2 Func Switch' on"
  are not set set in the chtrt5650 UCM sequences and thus are not present
  in the new component, in order to maximize reuse.
  

- Update chtrt5645 ucm variants to use bytcr/PlatformEnableSeq.conf component

  bytcr/PlatfromEnableSeq.conf sequence. This commit deletes those
  command sequences and loads the shared component directly.
  

- conf/ucm: bytcr-rt5651: Document mono speaker wiring

  During my recent work on the bytcht-es8316 UCM profile I realized that the
  bytcr-rt5651 devices with a single speaker use a differential setup just
  like the es8316 does. The tell-tale here is the speaker going quiet when
  playing the exact same sound on both channels when things are configured
  for stereo speakers.
  
  I've run some tests and the rt5651 does have a special mono balanced out
  mode for its line-out but using this results in the same sound (and the
  same loudness / volume of the sound) as our current solution, so adding
  support for this to the kernel buys us nothing.
  
  This commit makes no changes, it just documents my findings in a big
  comment for future reference.
  

- conf/ucm: bytcr-rt5651: Add bytcr-rt5651-stereo-spk-dmic-mic config

  compatible with RT5660 in I2S mode.
  
  The audio design on this IoT platform is as below:
   - Intel kabylake platform
   - connect the codec ALC3277 via SSP0
   - line-out and line-in with Micbias jacks
   - line-out mute control and jack detection of line-out and line-in
   - two HDMI ports with audio capability
  

- conf/ucm: chtrt5650: Add UCM config for chtrt5650

- ucm: Set default include path

  Many UCM profiles include the UCM profile components under ucm/*
  subdirectories and thusly put <searchdir:ucm> at each place.  This is
  rather cumbersome.
  
  This patch makes the UCM parser to set the default include path, so
  that each profile no longer needs to set searchdir.  All the
  <searchdir:ucm> lines currently found in the profiles are removed
  gracefully, too.
  
  For the needed implementation, a new helper,
  _snd_config_load_with_include() is introduced.  It's not exported,
  only for the use inside alsa-lib.
  

- conf: Move UCM profile snippets into components subdirectory

  We have placed UCM profile snippets to be included by the main config
  files also in the same directory, src/conf/ucm, it confuses alsaucm
  program that scans over all subdirectories.  It thinks such a file is
  also the main config file, and spews errors like:
    % alsaucm
    ALSA lib utils.c:67:(uc_mgr_config_load) could not open configuration file /usr/share/alsa/ucm/bytcr/bytcr.conf
    ALSA lib parser.c:1427:(load_master_config) error: could not parse configuration for card bytcr
    alsaucm: unable to obtain card list: No such file or directory
  
  Actually we already defined the subdirectory for such components, and
  they are skipped at parsing the main configs.  So we just need to move
  the files there -- this is what's done here.
  
  One more thing done here is to add a new component subdirectory,
  platforms, for definitions bytcr/* that don't match with neither the
  existing ones (codecs nor dsps).

  output swapped.
  

- conf/ucm: bytcr-rt5651: Add long-name UCM profiles

  After recent kernel work, the kernel now sets a long-name for bytcr-rt5651
  boards which indicates if a single (mono) speaker or stereo speakers are
  used and if in1, in2, or in1 and 2 are used for the internal mic(s) (the
  headset mic sofar is always on in3).
  
  This commit adds UCM profiles for bytcr-rt5651 boards using these new
  long-names, based on the generic bytcr-rt5651 profile.
  

- conf/ucm: bytcr-rt5651: Add mono speaker output profile

  Many rt5651 devices only have a single speaker and even though there is
  some external mixing done on the PCB, the quality of that mixing is quite
  poor and various sounds come out garbled when relying on the on PCB mixing.
  
  Using the codecs builtin mixer to mix left + right to the left output works
  much better. This commits adds a new MonoSpeaker.conf output profile which
  allows this.
  

- conf/ucm: bytcr-rt5651: Split into 1 .conf file per input / output

  Split the bytcr-rt5651 config into 1 .conf file per input / output as
  has already been done for the bytcr-rt5640 and the chtnau8824 profiles.
  
  This allows easy creation of long-name profiles with the specific input /
  output combinations found on a board without needing to copy and paste
  things.
  

- conf/ucm: bytcr-rt5651: Add support for mic input on various pins

  Note this commit replaces the pre-existing "Handset Microphone" and
  "Main Microphone" options, these come from the first commit of the
  bytcr-rt5651 UCM profile and were based on wrong assumptions about the
  input mappings. None of the existing devices has the Hand/Headset mic
  on IN1 as these options assumed.
  
  The rt5651 is used in various configurations with the Internal Mic(s)
  hooked up to IN1, IN2, or to IN1 and IN2 and the Headset Mic hooked up
  to IN3.
  
  Add support for all these to the generic bytcr-rt5651 profile and name
  them accotding to their input + functions.
  
  A follow up commit will add specialized longname configs which
  will only expose the inputs actually used on the board with that
  longname.

  Use the generic SSP enable sequence from bytcr/PlatformEnableSeq.conf,
  for boards using SSP2 this is identical the code it replaces and this
  adds support for boards using SSP0.
  
  This fixes sound not working on Bay Trail CR tablets with a rt5651 codec.
  
  This commit also calls the generic disable sequence on shutdown
  (this is new).
  

- conf/ucm: bytcr-rt5651: Change Speaker/Headphone en/disable sequences to fix switching

  pulseaudio will run the DisableSequence of the current playback device
  before running the EnableSequence of the new playback device.
  
  This causes the Platform Clock and BIAS to temporarily get turned off which
  on the rt5651 breaks audio-streams which are playing when switching.
  
  This commit moves the disabling to the EnableSequence of the other device
  fixing this.
  

- conf/ucm: bytcr-rt5651: Start with all outputs and inputs disabled

  Start with all switches disabled, so that e.g. the
  LOUT L/R Playback Switches are not left enabled when starting with
  headphones plugged in.
  
  This fixes the platform clock being kept on by these in some cases.
  
  While at also move the IN? Boost and IF1 ASRC Switch lines around
  a bit to match the order from https://github.com/plbossart/UCM so
  the profiles can be more easily compared.
  

- conf/ucm: bytcr-rt5651: Configure all volumes at 0dB

  The volumes are taken from this commit:
  https://github.com/plbossart/UCM/commit/753e2430cd0e6cafbf10c6b29b689dbd32ac5250
  
  That commit also adds line-in support, so it has not been
  taken in its entirety.
  

- conf/ucm: bytcr-rt5651: Do not use both DAC1 and HPVOL inputs for HP

  The headphones can either be driven directly from DAC1, or through
  the HP volume mixer chain to allow volume control, both can be enabled
  at the same time, but this should not be done.
  
  Mix only DAC1 to the headphones and not the HP volume path, there
  are 2 reasons to choice the DAC1 path;
  1) It is the power-on-reset default
  2) We don't expose the volume control to e.g. pulseaudio anyways so it
     is not useful
  
  While at it also move the "HPO MIX DAC1" and "HPO MIX HPVOL" entries up a
  bit so that they are no longer inbetween the "HPO L Playback Switch" and
  "HPO R Playback Switch" entries.

  speakers are used and wether dmic1, in1 or in3 is used for the internal
  mic (the headset mic sofar is always in2).
  
  This commit adds UCM profiles for bytcr-rt5640 boards using these new
  long-names, based on the generic bytcr-rt5640 profile.
  
  The added profiles have the unnecessary input / output options from the
  generic profile removed leaving only 2 input and 2 output options, which
  are automatically switched between by e.g. pulse based on jack-detect.
  

- conf/ucm: bytcr-rt5640: Add generic bytcr-rt5640 UCM profile

  https://github.com/plbossart/UCM/pull/31
  
  The profile has been split up into separate per input / output files to
  allow for creation of long-name profiles with the specific input / output
  combinations found on a board without needing to copy and paste things.
  
  Note this profile exports all inputs and both stereo/mono speaker setups
  even though a typical device will not use all. Ideally a long-name based
  device specific profile made up of the various parts should be used
  instead.

  Commit a192f52fc63a introduced an ucm profile for Rockchip Veyron-

  But similarly to DAISY-I2S, PAZ00 and most other profiles, the audio
  setup is pretty specific to a board type, so hogging the Rockchip name
  will make it harder for future Rockchip based boards to fit in nicely.
  
  And while Veyron also is a family of boards, all of them share the
  same audio setup. The ucm profile was not released with any official
  alsa release and the audio setup also isn't in the mainline kernel yet,
  so such a rename should be easily possible.

  Here correct it.
  

- conf/ucm: broadwell-rt286: add ucm config

  The configure should apply to all Broadwell-rt286 boards from Intel,
  like Wilson Beach SDS Ultrabook.
  

- conf/ucm: GoogleNyan: Add configuration

  Taken from the ChromeOS sources, this configuration should apply to all
  Nyan boards from Google, so far HP Chromebook 14 (nyan-blaze) and Acer
  Chromebook 13 (nyan-big).
  

- conf/ucm: PAZ00: add Toshiba AC100/Dynabook AZ new config

  Recent mainline kernels threat Toshiba AC100 audio hardware as hw:PAZ00
  vs old hw:tegraalc5632.
  
  This patch adds config files for new hw name and include them to
  makefiles.

- ASoC: topology: Fix bclk and fsync inversion in set_link_hw_format()

  The values of bclk and fsync are inverted WRT the codec. But the existing
  solution already works for Broadwell, see the alsa-lib config:
  
  `alsa-lib/src/conf/topology/broadwell/broadwell.conf`
  
  This commit provides the backwards-compatible solution to fix this misuse.
  This commit goes in pair with the corresponding patch for linux.

- conf: topology: Fix index mismatch for skl and bxt

  The topology index in the conf is set to 1, where the driver expects index
  set to 0. Fix the inconsistency.
  

- topology: Update physical link configurations in Broadwell text conf file

  To make this conf file a better example, add configurations for the
  physical link "Codec", same as that defined by Intel Broadwell upstream
  machine driver.
  

- conf: bxtrt298: Add topology conf file for bxt

  Add the conf file for bxt platform as well to define module
  private data.
  

- conf: sklrt286: define module private data through tuples in skylake

  In the conf file, module private data can be described through
  tuples instead of blobs defined by vendor defined structures.
  
  This patch defines the tuple section and the token list. The
  tokens are then used to build the tuple array.
  
  The module data may have both driver data and firmware data. The
  driver data is passed using the tuple array and the firmware data
  using byte data. A descriptor tuple array is defined to describe
  the succeeding data block.
  

- topology: Update PCM configurations in Broadwell text conf file

  To make this conf file a better example, update the name & ID of PCMs
  (front-end DAI link) and their cpu DAI (front-end DAI), same as those
  defined by Broadwell upstream driver.
  

- conf: topology: Add Skylake i2s conf

  The Skylake topology configuration for simple topology graph is
  provided. This exposes the PCM capabilities of the DSP.
  

- conf: topology: Add topology file for broadwell audio DSP

Changelog between 1.0.29 and 1.2.1 releases

alsa-firmware

Core

- Release v1.2.1

- Change FSF address (Franklin Street)

AICA (Dreamcast) Firmware

- Fix up aica firmware licensing

  The 3-clause BSD that this firmware uses requires more than just
  keeping the copyright notice, like license.txt currently says.
  Rather, it has has that "redistributions in binary form (which is
  what the ALSA Project is doing, since only the firmware binary is
  provided) must reproduce the above copyright notice, this list of
  conditions and the following disclaimer in the documentation and/or
  other materials provided with the distribution." This means that more
  than just the copyright notice needs to be included. This change is
  intended to address this by adding the parts that were omitted
  originally.
  

Cirrus Logic CS46xx Firmware

- Change FSF address (Franklin Street)

Digigram Echo Audio Firmware

- Change FSF address (Franklin Street)

Sound Blaster HDA CA0132 Firmware

- Add new firmware for Creative CA0132 HD-Audio Codec

  Support has been added for new cards through the ca0132 driver. These
  new firmware files are for these cards.
  
  [ NOTE: the files taken from the original PR to linux-firmware tree.
    These new files basically only addition to the already existing
    CA0132 firmware files, and follow the same license.
    The PR to linux-firmware tree was pending just because it was
    submitted by a third person, which is a quite unusual case.
