Some documents that listed on subsystem-apis have 'Linux' or 'The Linux'

0db78532ff ALSA: doc: Drop snd_dma_continuous_data() usages
Update the documentation to follow the recent change of the memory
allocation helpers.  The macro snd_dma_continuous_data() is gone, and
the driver needs to set up the coherent dma mask for allocating in the
lower memory addresses, instead.

0f1f7a6661 ALSA: usb-audio: Add quirk bits for enabling/disabling generic implicit fb
For making easier to test, add the new quirk_flags bits 17 and 18 to
enable and disable the generic implicit feedback mode.  The bit 17 is
equivalent with implicit_fb=1 option, applying the generic implicit
feedback sync mode.  OTOH, the bit 18 disables the implicit fb mode
forcibly.

ef248d9bd6 ALSA: hda/realtek: Add alc256-samsung-headphone fixup
This fixes the near-silence of the headphone jack on the ALC256-based
Samsung Galaxy Book Flex Alpha (NP730QCJ). The magic verbs were found
through trial and error, using known ALC298 hacks as inspiration. The
fixup is auto-enabled only when the NP730QCJ is detected. It can be
manually enabled using model=alc256-samsung-headphone.

ASoC: dmaengine: Introduce module option prealloc_buffer_size_kbytes
Currently, The fixed 512KB prealloc buffer size is too larger for
tiny memory kernel (such as 16MB memory). This patch adds the module
option "prealloc_buffer_size_kbytes" to specify prealloc buffer size.

It's suitable for cards which use the generic dmaengine pcm driver

ALSA: doc: Clarify IEC958 controls iface
The doc currently mentions that the IEC958 Playback Default should be
exposed on the PCM iface, and the Playback Mask on the mixer iface.

It's a bit confusing to advise to have two related controls on two
separate ifaces, and it looks like the drivers that currently expose
those controls use any combination of the mixer and PCM ifaces.

Let's try to clarify the situation a bit, and encourage to at least have
the controls on the same iface.

2d670ea2bd ALSA: jack: implement software jack injection via debugfs
This change adds audio jack injection feature through debugfs, with
this feature, we could validate alsa userspace changes by injecting
plugin or plugout events to the non-phantom audio jacks.

With this change, the sound core will build the folders
$debugfs_mount_dir/sound/cardN if SND_DEBUG and DEBUG_FS are enabled.
And if users also enable the SND_JACK_INJECTION_DEBUG, the jack
injection nodes will be built in the folder cardN like below:

$tree $debugfs_mount_dir/sound

        ├── mask_bits
        ├── status
        ├── sw_inject_enable
        └── type

The nodes kctl_id, mask_bits, status and type are read-only, users
could check jack or jack_kctl's information through them.

The nodes sw_inject_enable and jackin_inject are directly used for
injection. The sw_inject_enable is read-write, users could check if
software injection is enabled or not on this jack, and users could
echo 1 or 0 to enable or disable software injection on this jack. Once
the injection is enabled, the jack will not change by hardware events
anymore, once the injection is disabled, the jack will restore the
last reported hardware events to the jack. The jackin_inject is
write-only, if the injection is enabled, users could echo 1 or 0 to
this node to inject plugin or plugout events to this jack.

For the detailed usage information on these nodes, please refer to
Documentation/sound/designs/jack-injection.rst.

4f8af077a0 docs: Fix reST markup when linking to sections
During the process of converting the documentation to reST, some links
were converted using the following wrong syntax (and sometimes using %20
instead of spaces):

   `Display text <#section-name-in-html>`__

This syntax isn't valid according to the docutils' spec [1], but more
importantly, it is specific to HTML, since it uses '#' to link to an
HTML anchor.

The right syntax would instead use a docutils hyperlink reference as the
embedded URI to point to the section [2], that is:

   `Display text <Section Name_>`__

This syntax works in both HTML and PDF.

The LaTeX toolchain doesn't mind the HTML anchor syntax when generating
the pdf documentation (make pdfdocs), that is, the build succeeds but
the links don't work, but that syntax causes errors when trying to build
using the not-yet-merged rst2pdf:

   ValueError: format not resolved, probably missing URL scheme or undefined destination target for 'Forcing%20Quiescent%20States'

So, use the correct syntax in order to have it work in all different
output formats.

f36938aa74 ALSA: hda/realtek - Remove now-unnecessary XPS 13 headphone noise fixups
patch_realtek.c has historically failed to properly configure the PC
Beep Hidden Register for the ALC256 codec (among others). Depending on
your kernel version, symptoms of this misconfiguration can range from
chassis noise, picked up by a poorly-shielded PCBEEP trace, getting
amplified and played on your internal speaker and/or headphones to loud
feedback, which responds to the "Headphone Mic Boost" ALSA control,
getting played through your headphones. For details of the problem, see
the patch in this series titled "ALSA: hda/realtek - Set principled PC
Beep configuration for ALC256", which fixes the configuration.

These symptoms have been most noticed on the Dell XPS 13 9350 and 9360,
popular laptops that use the ALC256. As a result, several model-specific
fixups have been introduced to try and fix the problem, the most
egregious of which locks the "Headphone Mic Boost" control as a hack to
minimize noise from a feedback loop that shouldn't have been there in
the first place.

Now that the underlying issue has been fixed, remove all these fixups.
Remaining fixups needed by the XPS 13 are all picked up by existing pin
quirks.

This change should, for the XPS 13 9350/9360

 - Significantly increase volume and audio quality on headphones
 - Eliminate headphone popping on suspend/resume
 - Allow "Headphone Mic Boost" to be set again, making the headphone
   jack fully usable as a microphone jack too.

f128090491 ALSA: doc: Document PC Beep Hidden Register on Realtek ALC256
This codec (among others) has a hidden set of audio routes, apparently
designed to allow PC Beep output without a mixer widget on the output
path, which are controlled by an undocumented Realtek vendor register.
The default configuration of these routes means that certain inputs
aren't accessible, necessitating driver control of the register.
However, Realtek has provided no documentation of the register, instead
opting to fix issues by providing magic numbers, most of which have been
at least somewhat erroneous. These magic numbers then get copied by
others into model-specific fixups, leading to a fragmented and buggy set
of configurations.

To get out of this situation, I've reverse engineered the register by
flipping bits and observing how the codec's behavior changes. This
commit documents my findings. It does not change any code.

Following the example in cb2cf0de11 ("ASoC: soc-core: care Codec <->
Codec case by non_legacy_dai_naming"), determine if a DAI link contains
only codec DAIs by examining the non_legacy_dai_naming flag in each
DAI's component.

For now, we assume there is only one or a small set of valid PCM stream
parameters, so num_params == 1 is good enough. We also assume that the
same params are valid for all supported streams. params is set to the
subset of parameters common among all DAIs, and then the existing code
automatically chooses the highest quality of the remaining values when

fb95aae6e6 sound updates for 5.6-rc1
As diffstat shows we've had again a lot of works done for this cycle:
 majority of changes are the continued componentization and code
 refactoring in ASoC, the tree-wide PCM API updates and cleanups
 and SOF updates while a few ASoC driver updates are seen, too.
 
 Here we go, some highlights:
 
 Core:
 - Finally y2038 support landed to ALSA ABI;
   some ioctls have been extended and lots of tricks were applied
 - Applying the new managed PCM buffer API to all drivers;
   the API itself was already merged in 5.5
 - The already deprecated dimension support in ALSA control API is
   dropped completely now
 - Verification of ALSA control elements to catch API misuses
 
 ASoC:
 - Further code refactorings and moving things to the component level
 - Lots of updates and improvements on SOF / Intel drivers;
   now including common HDMI driver and SoundWire support
 - New driver support for Ingenic JZ4770, Mediatek MT6660, Qualcomm
   WCD934x and WSA881x, and Realtek RT700, RT711, RT715, RT1011, RT1015
   and RT1308
 
 HD-audio:
 - Improved ring-buffer communications using waitqueue
 - Drop the superfluous buffer preallocation on x86
 
 Others:
 - Many code cleanups, mostly constifications over the whole tree
 - USB-audio: quirks for MOTU, Corsair Virtuoso, Line6 Helix
 - FireWire: code refactoring for oxfw and dice drivers

d8cac6207e ALSA: cmipci: Allow disabling MPU port via module option
Patrick May reported that his sound card with CMI8378 chip causes a
crash / reboot when accessing the MIDI port that isn't actually
present on the board.  Moreover, despite of the documentation,
passing mpu_port=0 doesn't disable the MIDI port on this board.

It implies that the chip is a newer revision and the MPU401 port is
integrated and mapped on the PCI register.  For this chip model, the
driver enables the MPU port unconditionally, so far.

Although fixing the unexpected reboot would be the best solution, it's
not so trivial to identify the cause.  So, as a plan B, this patch
extends the existing mpu_port option usage to allow disabling the port
by specifying the value 0, just like we applied for fm_port option in
commit 2f24d159d5 ("[ALSA] cmipci - Allow to disable integrated FM
port").  As default, the MPU port is still enabled, but user can pass
mpu_port=0 to disable it.

08422d2c55 ALSA: memalloc: Allow NULL device for SNDRV_DMA_TYPE_CONTINUOUS type
Currently we pass the artificial device pointer to the allocation
helper in the case of SNDRV_DMA_TYPE_CONTINUOUS for passing the GFP
flags.  But all common cases are the allocations with GFP_KERNEL, and
it's messy to put this in each place.

In this patch, the memalloc core helper is changed to accept the NULL
device pointer and it treats as the default mode, GFP_KERNEL, so that
all callers can omit the complex argument but just leave NULL.

6ab8ad3160 sound updates for 5.4
As shown in diffstat and logs, it was again a busy development
 cycle at this time, too.  The most significant changes are still
 on-going refactoring / modernization works for ASoC core and
 drivers, but there are lots of other changes as well.  Here we go,
 some highlights below:
 
 ASoC:
 - Quite lots of cleanup / refactoring of ASoC core and APIs;
   most of them are systematic, but also including cleanups and
   modernization
 
 - A bulk of updates for some ASoC platforms, Freescale, sunxi and
   Intel SST/SOF
 
 - Initial support for Sound Open Firmware on i.MX8
 
 - Removal of deprecated w90x900 and nuc900 drivers
 
 - New support for Cirrus Logic CS47L15 and CS47L92, Freescale i.MX
   7ULP and 8MQ, Meson G12A and NXP UDA1334
 
 USB-audio:
 - More validations of descriptor units for hardening against bugs
   reported by fuzzers
 
 - PCM device assignment workaround for a past call-order change
 
 - Scarlett Gen2 mixer interface, a few more more quirks
 
 HD-audio:
 - Support for audio component with AMD/ATI and Nvidia HDMI codecs
 
 - Clean up HD-audio core and remove indirect access ops for Intel SOF
 
 - DMIC detection at probe; it would make systems automatically falling
   back to SST/SOF driver on devices that need DMIC handling.
   Needs a new Kconfig to set, and beware that it's still new and a bit
   experimental
 
 FireWire:
 - Lots of code refactoring and cleanups

a2ef03fe61 ALSA: hda - Add a quirk model for fixing Huawei Matebook X right speaker
[ This is rather a revival of the patch Tomas sent in months ago, but
  applying only with the quirk model option -- tiwai ]

Hard coded coefficients to make Huawuei Matebook X right speaker
work. The Matebook X has a ALC298, please refer to bug 197801 on
how these numbers were reverse engineered from the Windows driver

The reversed engineered sequence represents a repeating pattern
of verbs, and the only values that are changing periodically are
written on indexes 0x23 and 0x25:

0x500, 0x23
0x400, VALUE1
0x500, 0x25
0x400, VALUE2

* skipped reading sequences (0x500 - 0xc00 sequences are ignored)
* static values from reverse engineering are used

NOTE: since a significant risk is still considered, this is provided
as an experimental fix that isn't applied as default for now.  For
enabling the fix, you'll have to choose huawei-mbx-stereo via model
option of snd-hda-intel module.

If we get feedback from users that this works stably, we may apply it
per default.

[ Some coding style fixes and replacement with AC_VERB_* by tiwai ]

ASoC: More changes for v5.1

Another batch of changes for ASoC, no big core changes - it's mainly
small fixes and improvements for individual drivers.

 - A big refresh and cleanup of the Samsung drivers, fixing a number of
   issues which allow the driver to be used with a wider range of
   userspaces.
 - Fixes for the Intel drivers to make them more standard so less likely
   to get bitten by core issues.
 - New driver for Cirrus Logic CS35L26.

0b6a2c9cf4 ALSA: isa: Avoid passing NULL to memory allocators
We used to pass NULL to memory allocators for ISA devices due to
historical reasons.  But we prefer rather a proper device object to be
assigned, so let's fix it by replacing snd_dma_isa_data() call with
card->dev reference, and kill snd_dma_isa_data() definition.

806654a966 Documentation: Use "while" instead of "whilst"
Whilst making an unrelated change to some Documentation, Linus sayeth:

  | Afaik, even in Britain, "whilst" is unusual and considered more
  | formal, and "while" is the common word.
  |
  | [...]
  |
  | Can we just admit that we work with computers, and we don't need to
  | use þe eald Englisc spelling of words that most of the world never
  | uses?

dictionary.com refers to the word as "Chiefly British", which is
probably an undesirable attribute for technical documentation.

Replace all occurrences under Documentation/ with "while".

f274baa49b ALSA: usb-audio: Allow non-vmalloc buffer for PCM buffers
Currently, USB-audio driver allocates the PCM buffer via vmalloc(), as
this serves merely as an intermediate buffer that is copied to each
URB transfer buffer.  This works well in general on x86, but on some
archs this may result in cache coherency issues when mmap is used.
OTOH, it works also on such arch unless mmap is used.

This patch is a step for mitigating the inconvenience; a new module
option "use_vmalloc" is provided so that user can choose to allocate
the DMA coherent buffer instead of the existing vmalloc buffer.
The drawback is that it'd be the standard dma_alloc_coherent() calls
and the system would require contiguous pages on non-x86 archs.

Note that it's a global option and not dynamically switchable since
the buffer is pre-allocated at the probe time.  In theory, it's
possible to be switchable, but it'd be trickier and racier.

As default use_vmalloc option is set to true, so that the old behavior
is kept.  For allowing the coherent mmap on ARM or MIPS, pass
use_vmalloc=0 option explicitly.

4e4510fec4 sound updates for 4.15-rc1
There are no big surprising changes in this cycle, yet not too
 boring, either.  The biggest change from diffstat POV is the removal
 of the legacy OSS driver codes that have been already disabled for a
 long time.  This will bring a few trivial merge conflicts.
 
 As new features in ASoC side, there are two things: a new AC97 bus
 implementation and AMD Stony platform support.  Both include the
 relevant changes shared with other subsystems, e.g. AC97 MFD changes
 and DRM AMD changes.
 
 Some other highlighted topics are:
 - A bunch of USB-audio drivers got the hardening against the malicious
   device accesses with a new helper code for endpoint sanity check.

Pull sound updates from Takashi Iwai:
 "There are no big surprising changes in this cycle, yet not too boring,
  either. The biggest change from diffstat POV is the removal of the
  legacy OSS driver codes that have been already disabled for a long
  time. This will bring a few trivial merge conflicts.

  As new features in ASoC side, there are two things: a new AC97 bus
  implementation and AMD Stony platform support. Both include the
  relevant changes shared with other subsystems, e.g. AC97 MFD changes
  and DRM AMD changes.

  Some other highlighted topics are:

   - A bunch of USB-audio drivers got the hardening against the
     malicious device accesses with a new helper code for endpoint
     sanity check

   - Lots of cleanups for ASoC Intel platform code, including support
     for their open source audio firmware

   - Continued ASoC core componentization works

   - Support for scaling MCLK with sample rate in ASoC simple-card

   - Stabler PCM hot-unplug capability, especially for ASoC usages"

727dede0ba sound: Retire OSS
Since no complaints have been raised after disabling the build of OSS
(Open Sound System) by the commit 31cbee6a56 ("sound: Disable the
build of OSS drivers"), let's finally drop the whole code and
documentation.

Some glue codes are still left intact since sound/oss/dmasound stuff
remains -- which is an independent implementation solely for m68k, and
it's not covered by ALSA yet.

Also, a couple of API header files (linux/sound.h and
linux/soundcard.h) are kept remaining as well, since the OSS API
itself is still supported by ALSA OSS emulation, and applications can
refer to these.

Where we're at it, some help texts in the top-level Kconfig are
adjusted, too (who still needs to specify I/O port in kbuild
nowadays?).

920f2ecdf6 sound updates for 4.13-rc1
This development cycle resulted in a fair amount of changes in both
 core and driver sides.  The most significant change in ALSA core is
 about PCM.  Also the support of of-graph card and the new DAPM widget
 for DSP are noteworthy changes in ASoC core.  And there're lots of
 small changes splat over the tree, as you can see in diffstat.
 
 Below are a few highlights:
 
 ALSA core:
 - Removal of set_fs() hackery from PCM core stuff, and the code
   reorganization / optimization thereafter
 - Improved support of PCM ack ops, and a new ABI for improved
   control/status mmap handling
 - Lots of constifications in various codes
 
 ASoC core:
 - The support of of-graph card, which may work as a better generic
   device for a replacement of simple-card
 - New widget types intended mainly for use with DSPs
 
 ASoC drivers:
 - New drivers for Allwinner V3s SoCs
 - Ensonic ES8316 codec support
 - More Intel SKL and KBL works
 - More device support for Intel SST Atom (mostly for cheap tablets and
   2-in-1 devices)
 - Support for Rockchip PDM controllers
 - Support for STM32 I2S and S/PDIF controllers
 - Support for ZTE AUD96P22 codecs
 
 HD-audio:
 - Support of new Realtek codecs (ALC215/ALC285/ALC289), more quirks
   for HP and Dell machines
 - A few more fixes for i915 component binding
 
 Note that of-graph change may bring the conflicts with a later pull
 request of devicetree, as currently found in linux-next.
