: 
:  Adding a new Conexant CX2072X codec profile and reusing the existing
:  BYT/CHT platform snippets.
: 
:  Currently tested only on ASUS E200HA laptop.
: 
===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.

:  Fixes: 54931e5a5455 ("pcm: Add thread-safety to PCM API")
:  Reported-by: Ben Russell <thematrixeatsyou@gmail.com>
: - 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
: 
:  Reviewed-by: Timo Wischer <twischer@de.adit-jv.com>
: - 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
: 
:  Reviewed-by: Timo Wischer <twischer@de.adit-jv.com>
: - 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
: 
:  Reviewed-by: Timo Wischer <twischer@de.adit-jv.com>
: - 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
: 
:  Reviewed-by: Timo Wischer <twischer@de.adit-jv.com>
: - 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,

: - 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

: 
:  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

: 
===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"

: 
:  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 {
:  ...
:  }
:  }

:  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.

: - 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

:  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.

:  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.

: 
: - Factor out rt5645 variants Headset+Digital Mic UCM shared {en,dis}able sequences

: 
:  Move common enable sequences for rt5645 variants and rt5650
:  UCM configurations into a shared component. The corresponding

:  creating components for.
:

:  Factor out the common enable and disable sequences used
:  in rt5645 variants, including the rt5650. Move the sequences

: 
: - 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.

:  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

: - 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).

:  USB-audio device on Dell WD15 docking station provides two individual
:  PCM streams, one for headphone and another for line out.  A UCM
:  profile gives the proper roles for these.
: 
: - conf/ucm: chtrt5645: At config for the Lenovo Ideapad Miix 320
: 
:  The Lenovo Ideapad Miix 320 uses a digital mic connected to the DMIC2 input
:  (unlike the Asus T100HA which has it connected to the DMIC1 input), add a
:  long-name config specific for the Miix 320, which is a copy of the standard
:  chtrt5645 config with the internal analog mic section replaced with one
:  for a digital mic connected to the DMIC2 input.
: 
: - conf/ucm: chtrt5645: At config for the Asus T100HA
: 
:  The Asus T100HA uses a digital mic rather then an analog one, add
:  long-name config specific for the T100HA, which is a copy of the standard
:  chtrt5645 config with the internal analog mic section replaced with one
:  for the digital mic found on the Asus T100HA.
: 
: - conf/ucm: chtrt5645: Fix recording from internal analog microphone
: 
:  The internal analog mic switch is called 'Int Analog Mic Switch'
:  (not 'Int Mic Switch') and is connected to BST2 not BST1.
: 
:  Also change the analog mic volume levels so that we get better
:  audio / less noise.

: - conf/ucm: chtrt5645: Microphone recording fixes
: 
:  Apply microphone recording changes from:
:  https://github.com/plbossart/UCM.git

: - conf/ucm: increase the input volume for LineIn
: 
:  Otherwise, the boost value is 0, and the sound captured from that
:  LineIn jack is too weak for users.
: 
: - conf/ucm: Add chtrt5645-mono-speaker-analog-mic configuration
: 
:  Add a configuration for Cherry Trail boards which use a rt5645 codec
:  connected to a mono speaker and with an analog mic on IN2N + IN2P.
: 
:  The chtrt5645-mono-speaker-analog-mic/HiFi.conf for this is based on the
:  latest version from https://github.com/plbossart/UCM/tree/master/chtrt5645
:  with all the unused input options removed and some changes made to make
:  the analog mic work.
: 
:  This commit also adds 2 ucm dirs with the longname of 2 boards known to use
:  this setup, which simply contain a symlink to the generic
:  chtrt5645-mono-speaker-analog-mic entry.
: 
: - conf/ucm: Add Gigabyte mobo UCM profile with dual HD-audio codecs
: 
:  Like the previous Lenovo laptops, some Gigabyte mobos have dual
:  HD-audio codecs and need to switch dynamically via UCM profile.
:  Reuse the same profile as Lenovo dual codecs, so far.
: 
: - conf/ucm: Add dual HD-audio codecs config for Lenovo
: 
:  Some recent Lenovo laptops have dual codecs and we need to switch them
:  accordingly.  The kernel side already contains a fix and gives the
:  unique longname string for identifying the board, and here we hook up
:  the corresponding UCM profile.
: 
:  The profile was corrected and tested by Hui Wang on Lenovo p520.

: - conf/ucm: rt5651: Mute speakers on boot
: 
:  The UCM configuration is enabling the speakers in the SectionDefaults.
:  This is a problem when booting with an headset already connected since
:  the audio output is routed at the same time both on speakers and
:  heaphones until the jack is disconnected and reconnected again.
: 
:  Fix this disabling all the outputs in the default mixer configuration.
: 
: - conf/ucm: rt5651: Add missing cdev
: 
: - conf/ucm: rt5651: Fix HiFi file name

: 
: - conf/ucm: DB410c-HiFi: add CIC selection
: 
:  This patch adds CIC selection controls which have been added recently to
:  the kernel to select mic source.
: 
:  Without this patch user has to manually select the control to record
:  from DMIC or AMIC.
: 
: - conf/ucm: broxton: add broxton-rt298 conf files
: 
:  This adds the UCM conf files for broxton enabling with rt298 codec on

: 
:  Add a UCM configuration for the rt5645 codec on Intel's Cherry-Trail
:  platform. Tested on the Microsoft Surface 3.
: 
: - conf/ucm: ROCKCHIP-I2S: rename to VEYRON-I2S
: 
:  Commit a192f52fc63a introduced an ucm profile for Rockchip Veyron-
:  Chromebooks by taking the ucm profile from the ChromeOS userspace.
: 
:  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.
: 
:  Fixes: a192f52fc63a ("conf/ucm: ROCKCHIP-I2S: add Rockchip I2S UCM config.")
: - conf/ucm: ROCKCHIP-I2S: add Rockchip I2S UCM config.
:

: - conf/ucm: broadwell-rt286: change to use the correct jack kcontrol name
: 
:  The headset jack has two kctls: "Headphone Jack" and "Mic Jack",
:  we need switch speaker output according to the former JackControl.
:  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

: - 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.

:  tokens are then used to build the tuple array.
: 
:  The module data may have both driver data and firmware data. The

==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.
