Subject: ALSA: cs46xx: Move DSP blob out of kernel tree

... and load from the external firmware files.

The firmware binary blobs in cs46xx driver have been in a gray zone
regarding the license.  It's most likely should be OK, but still
unclear.  And, the size isn't that small, too.

-// the samples 'as they are' with no alteration from a PCMreader
-// SCB (DMA from host) to any other SCB. This is useful for AC3 through SPDIF.
-// SRC (source rate converters) task always alters the samples in somehow,

-// The alterations are not audible, but AC3 wont work.

Subject: ASoC: soc-pcm: add symmetry for channels and sample bits

Some SoCs can only work in mono or stereo mode at one time. So if
we let them capture a mono stream while playing a stereo stream,
there might be a problem occur to one of these two streams: double
paced or slowed down.

In soc-pcm.c, we have soc_pcm_apply_symmetry() to apply the rate
symmetry. But we don't have one for channels.

Likewise, we can treat symmetric_rate as a solution for those SoCs
or CODECs which can not handle asymmetrical LRCLK. But it's also
impossible for them to handle asymmetrical BCLK. And accodring to
BCLK = LRCLK * channel number * slot size(fixed or sample bits),
sample bits might also be a problem if they are not using a fixed
slot size.

Thus, this patch applys symmetry for channels and sample bits.

Meanwhile, there might be a race between two substreams if starting
simultaneously. Previously, we only added warning to compalin but
still using conservative way to let it carry on. However, this patch
rejects the second stream with any unmatched parameter to make sure
the first existing stream won't be broken.

Subject: ASoC: soc-pcm: move DAIs parameters cleaning into hw_free()

We're now applying soc_hw_params_symmetry() to reject unmatched parameters
while we clear parameters in soc_pcm_close(). So here's a use case might be
broken by this mechanism: aplay -Dhw:0 44100.wav 48000.wav 32000.wav

In this case, we call soc_pcm_open()->soc_pcm_hw_params()->soc_pcm_hw_free()
->soc_pcm_hw_params()->soc_pcm_hw_free()->soc_pcm_close() in order. As we
only clear parameters in soc_pcm_close(). The parameters would be remained
in the system even if the playback of 44100.wav is finished.

Thus, this patch is trying to move parameters cleaning into hw_free() so that
the system can continue to serve this kind of use case.

Also, since we set them in hw_params(), it should be better to clear them in
hw_free() for symmetry.

Subject: ASoC: omap: mcbsp, mcpdm, dmic: raw read and write endian fix

All OMAP IP blocks expect LE data, but CPU may operate in BE mode.
Need to use endian neutral functions to read/write h/w registers.
I.e instead of __raw_read[lw] and __raw_write[lw] functions code
need to use read[lw]_relaxed and write[lw]_relaxed functions.
If the first simply reads/writes register, the second will byteswap
it if host operates in BE mode.

Changes are trivial sed like replacement of __raw_xxx functions
with xxx_relaxed variant.

Subject: ASoC: rcar: some dubious one-bit signed bitfields

Because these are signed they can either be 0 or -1 instead of 0 and 1
as intended.  It doesn't cause a problem from what I can see, but it's
dangerous and Sparse complains:

		error: dubious one-bit signed bitfield

We have other Intel platforms coming having the Smart Sound Technology (SST)
so rename the mid-x86 directory to intel as originally directory name
reflected only Intel MID platform.

Subject: ASoC: Add support for BCM2835

This driver adds support for digital audio (I2S)
for the BCM2835 SoC that is used by the
Raspberry Pi. External audio codecs can be
connected to the Raspberry Pi via P5 header.

It relies on cyclic DMA engine support for BCM2835.

Subject: ALSA: hda - Split the generic parser as an individual module

Drop the hard dependency on the generic parser code and load / unload
the generic parser code dynamically if built as a module.  This allows
us to avoid the generic parser if only HDMI/DP codecs are found.

Subject: ALSA: hda - Bind with HDMI codec parser automatically

If a codec contains only the digital outputs, it's very likely a
HDMI/DP codec, which isn't supported by the generic parser but via
HDMI codec parser code.  Detect such a case and bind with the proper
parser object if available.

Subject: ALSA: hda - Refactor pm notification in hda_codec.c

No functional change.

- codec->pm_down_notified flag is renamed to codec->pm_up_notified
  flag (and takes the reversed meaning), which is managed solely in
  hda_call_pm_notify() now.

- The explicit call of hda_call_pm_notify() is moved into
  hda_keep_power_on().

- Removed a redundant call of hda_call_pm_notify() in
  snd_hda_power_up(), as it's called in hda_call_codec_resume()
  anyway.

Now we fixed the long-standing bugs of runtime PM, let's enable
Panther Point again.  The runtime PM was disabled in the HDMI codec
driver due to the S3 issue, and this should have been fixed now.

Subject: ALSA: hda - Disable runtime PM when EPSS is unavailable

According to Mengdong, we shouldn't enable runtime PM when a codec
doesn't support EPSS, based on the experiences on Windows.
We have already this check in HDMI codec drivers, but now apply it in
general in hda_codec.c.

Subject: ALSA: hda - suspend codecs in parallel

The time to suspend a single codec may be several hundreds of ms. When runtime
power saving is disabled, driver suspend time can be long especially when there
are more than one codec on the bus.

To reduce driver suspend time, this patch creates a work queue for the bus, and
suspends the codecs in parallel if there are multiple codecs on the bus.

Subject: ALSA: hda - resume codecs in parallel

To reduce driver resume time, this patch resumes the codecs in parallel
if there are multiple codecs on the bus.

- The PM workqueue of bus is also used to parallel resuming multiple codecs.
- The work item 'pm_work' is renamed to 'suspend_work' to parallel suspending
  codecs.
- Add a work item 'resume_work' to parallel resuming codecs.

Subject: ASoC: wm8994: Move DCS done IRQ request later

once code return from request_threaded_irq, irq was setup enabled by
default, but completion var dcs_done not got initialized yet, if then a
dcs done irq was raised, system will got hung as the sync mechanism is
invalid now.

so this patch move dcs done irq request to the end of initialization
of completion.

Subject: ASoC: Add resource managed snd_dmaengine_pcm_register()

For many drivers using the generic dmaengine PCM driver one of the few (or the
only) things left to do in the drivers remove function is to unregister the PCM
device. This patch adds a resource managed version of snd_dmaengine_pcm_register()
which makes it possible to simplify the remove function as well as the error
path in the probe function for those drivers.

Current rcar driver is supporting Gen1,
and Gen2 will be supported soon.
Then, some registers are used from Gen1 only,
or from Gen2 only.
To avoid NULL pointer access, this patch adds
register accessible check function.

Subject: ASoC: rcar: remove .path_init/exit from rsnd_gen_ops

rsnd_gen_ops has .path_init/exit callback function
which cares SRU/SSI (if Gen1) SCU/SSIU/SSI (if Gen2)
path settings.
But, the differences between Gen1/Gen2 are cared
in ssi.c/scu.c, and the path itself is same in Gen1/Gen2.
This patch removes .path_init/exit callback.

Subject: ASoC: rcar: remove rcar_gen_ops

Current rcar driver gen.c is using rcar_gen_ops
which was made with the assumption that
Gen1 and Gen2 need different behavior.
but it was not needed.
This patch removes unnecessary complex method.

Subject: ALSA: hda/realtek - Remove depop delay for suspend and resume if
 applicable

This patch defines a flag "no_depop_delay" in alc_spec. If this flag is set,
delay in alc_eapd_shutup and alc_resume will be skipped.

Machine-specific fixup can set this flag to reduce suspend/resume time, if
the codec and hardware analog design can avoid pop noise without this delay.

Subject: ALSA: hda - fixup ALC262 to remove depop delay on Intel BayleyBay
 board

This patch defines a fixup 'alc_fixup_no_depop_delay', which sets alc_spec flag
'no_depop_delay' to indicate skipping delay in Realtek codec suspend/resume.

And Intel Baytrail BayleyBay board applies this fixup to reduce driver
suspend/resume time.

Subject: ALSA: hda - allow a codec to define its own depop delay time

This patch adds 'depop_delay' to struct hda_codec, to indicate a depop delay
time in ms when power-down, in function set_power_state() to D3.

Default value is -1, for a default delay time.
Machine fixup can set a suitable value according to the codec chip and HW audio
design.

Subject: ASoC: ak4642: Convert to direct regmap API usage

This moves us towards being able to remove the ASoC level I/O code which
duplicates regmap functionality. Currently the only difference between
the supported devices in the driver is the regmap so we can replace the
CODEC driver selections with regmap selection instead.

Subject: ASoC: fsl: imx-ssi: omit ssi counter to avoid harm in unbalanced
 situation

Unbalanced calls to imx_ssi_trigger() may result in endless
SSI activity and thus provoke eternal sound. While on the first glance,
the switch statement looks pretty symmetric, the SUSPEND/RESUME
pair is not: the suspend case comes along snd_pcm_suspend_all(),
which for fsl/imx-pcm-fiq is called only at snd_soc_suspend(),
but the resume case originates straight from the SNDRV_PCM_IOCTL_RESUME.
This way userland may provoke an unbalanced resume, which might cause
the ssi->enabled counter to increase and never return to zero again,
so eventually SSI_SCR_SSIEN is never disabled.

As the information on whether to enable the SSI or not is contained
in the two bits for TE/RE, we save all the software mirroring of
hardware state here and simply use the hardware register itself
to keep the state of whether someone is currently playing or capturing.

This is essentially the same stuff as in sound/soc/fsl/imx-pcm-fiq.c
which I send a patch for three days ago. Astonishing enough this
highly fragile scheme is used twice in parallel to serve the very
same control function, synchronously: Once out of sync you are lost
until reboot.

Note, that these fixes wont prevent state machine distortion on alsa
level to cut sound or the like. It just makes sure we have a chance
to synchronise again later on.

The device does not support anything other than I2C (at least with the
current driver) so save code.

Subject: ALSA: hda - Always do delayed probes for HD-audio devices

HD-audio devices tend to take long time for finishing the whole
probing procedure.  In this patch, the time-consuming part of the
probing procedure, the codec probe and the rest initializations, are
moved in the work, so that they can be done asynchronously in parallel
with probes of other devices.

Since we already have this mechanism in the driver code for the
firmware and i915 request_symbol() stuff, we just need to enable it
always; the resultant patch even reduces more lines, which is an
additional bonus.

Credit goes to David Henningsson, who suggested this workaround.

Subject: ASoC: fsl_ssi: Add monaural audio support for non-ac97 interface

The normal mode of SSI allows it to send/receive data to/from the first
slot of each period. So we can use this normal mode to trick I2S signal
by puting/getting data to/from the first slot only (the left channel)
so as to support monaural audio playback and recording.

Subject: ASoC: jz4740: Use the generic dmaengine PCM driver

Now that there is a dmaengine driver for the jz4740 DMA core we can use the
generic dmaengine PCM driver. This allows us to remove the custom jz4740-pcm
code completely.

Subject: ASoC: soc-pcm: Drop the redundant snd_soc_dai_digital_mute() in
 soc_pcm_close()

This patch removed the redundant snd_soc_dai_digital_mute() in close() since
it's better to mute in hw_free() which's slightly earlier and symmetrical for
the case of reconfiguration: 'aplay 44k1.wav 48k.wav', for example, will be
open()->hw_params()->prepare(unmute)->playi1ng->hw_free(mute)->hw_params()->
parepare(unmute)->playing->hw_free(mute)->close()

This will allow a marginal speed improvement when used with a bus that
supports async I/O by reducing the amount of context thrashing between
writes, allowing the bus to be more fully utilised.

Subject: ALSA: hda - skip depop delay before D3 for Haswell and Valleyview2
 display codec

This patch skips the default depop delay before D3 for Haswell (10 ms) and
Valleyview2 (100 ms) display codec, to reduce codec suspend time.

The analog part of display audio is implemented in the external display. Some
displays have weak pop noise while others not when suspending, no matter there
is the default delay or not.

The loopback mixing paths aren't initialized correctly at init
callback.  Mostly this is harmless as codecs usually set the mute
state as default, but we still should make sure.

Subject: ALSA: hda - Ignore small negative LPIB delay correction

Sometimes the hardware reports LPIB being advanced than POSBUF.
When this happens, the driver adjusts to a positive value by adding
the buffer size.  Then the driver detects it as an error (greater than
the period size), and stops the LPIB delay account from this point
on.

When I took a close look at these conditions, the values shown are all
very small numbers, and it'd be better to just ignore these values
instead of discontinuing the LPIB delay correction.

In this patch, the driver checks a negative delay value and ignores if
it's a significantly small error.  Currently the threshold is set to
64 frames, but could be smaller.

Subject: ALSA: hda - Enable stereo mix as default for AD and VIA codecs

AD and VIA codecs had stereo mixer input enabled as default before
moving to the generic parser, and people think the lack of such a
regression.  In this patch, the stereo mixer input is added back to
the input selection if no auto-mic is available, and if it's not
disabled explicitly via hint.  This should satisfy most of demands,
i.e. stereo mix on desktop machines like what it worked before, and it
still keeps the new auto-mic feature on laptops.

Subject: ALSA: hda - Split verb definitions into sound/hda_verbs.h

Since there are more HD-audio compatible codecs, move the definitions
of HD-audio verbs into common header location, include/sound, so that
it can be included cleanly from other drivers than HD-audio driver.

Subject: ASoC: Add support for the Analog Devices AXI-I2S core

This patch adds support for the AXI-I2S softcore. The core implements a simple
bidirectional I2S transceiver and is used by Analog Devices in some of their
reference designs for various FPGA platforms.

The driver uses the generic PCM dmaengine driver for its PCM. The only
restriction is that we need to set the SND_DMAENGINE_PCM_FLAG_NO_RESIDUE flag as
the dmaengine driver for the DMA core (PL330) that is used with this core has no
residue reporting capabilities yet. This will be fixed in the future though.

Subject: ASoC: Add support for the Analog Devices AXI-SPDIF driver

This patch adds a ASoC driver for the AXI-SPDIF softcore. The core implements a
simple SPDIF transmitter and is used on some Analog Devices' reference designs
for various FPGA platforms. For now the driver only support the PL330 as the the
DMA controller.

The driver uses the generic PCM dmaengine driver for its PCM. The only
restriction is that we need to set the SND_DMAENGINE_PCM_FLAG_NO_RESIDUE flag as
the dmaengine driver for the DMA core (PL330) that is used with this core has no
residue reporting capabilities yet. This will be fixed in the future though.

Subject: ASoC: tlv320aic3x: no mono controls 3007 model

if codec driver is used for AIC3X_MODEL_3007 the mono iout controls overwrite
registers for class-d amplifier.
classd amplifier controls are only used for AIC3X_MODEL_3007.

Removing all mono snd_kcontrol_new, snd_soc_dapm_widget, snd_soc_dapm_route
and aic3x_init stuff from common code and call only for not AIC3X_MODEL_3007
codecs.

Testet only with AIC3X_MODEL_3007

Subject: ASoC: restructure dmaengine_pcm_request_chan_of()

Restructure the internals of dmaengine_pcm_request_chan_of() as a loop
over all channels to be allocated. This makes it easier to add logic
that applies to all allocated channels, without having to duplicate that
logic in each of the half-duplex/full-duplex paths.

Subject: ASoC: dmaengine: add custom DMA config to snd_dmaengine_pcm_config

Add fields to struct snd_dmaengine_pcm_config to allow custom:

- DMA channel names.

  This is useful when the default "tx" and "rx" channel names don't
  apply, for example if a HW module supports multiple channels, each
  having different DMA channel names. This is the case with the FIFOs
  in Tegra's AHUB. This new facility can replace
  SND_DMAENGINE_PCM_FLAG_CUSTOM_CHANNEL_NAME.

- DMA device

  This allows requesting DMA channels for a device other than the device
  which is registering the "PCM" driver. This is quite unusual, but is
  currently useful on Tegra. In much HW, and in Tegra20, each DAI HW
  module contains its own FIFOs which DMA writes to. However, in Tegra30,
  the DMA FIFOs were split out AHUB HW module, which then routes the data
  through a cross-bar, and into the DAI HW modules. However, the current
  ASoC driver structure does not expose this detail, and acts as if the
  FIFOs are still part of the DAI HW modules. Consequently, the "PCM"
  driver is registered with the DAI HW module, yet the DMA channels must
  be looked up in the AHUB HW module's device tree node. This new config
  field allows that to happen. Eventually, the Tegra drivers will be
  reworked to fully expose the AHUB, and this config field can be
  removed.

Subject: ASoC: davinci-mcasp: Move private struct definition to source file

Since it is a private struct strictly used by the davinci-mcasp driver it
can be moved from header file to the source file.

Subject: ASoC: davinci-mcasp: Rename private struct and it's users (dev ->
 mcasp)

Rename the private struct from davinci_audio_dev to davinci_mcasp.
Change the local use of the pointer to this struct from *dev to *mcasp.

The aim is to have better readable code for the first look since having
dev->xxxx in the code when using the local private struct is a bit
surprising.

Subject: ASoC: davinci-mcasp: Be consistent with the use of base in
 davinci_mcasp_set_dai_fmt

Replace mcasp->base use with plain base in the davinci_mcasp_set_dai_fmt()
function since it has been already used by the remaining part of the function.

Date: Thu, 14 Nov 2013 11:35:31 +0200
Subject: ASoC: davinci-mcasp: Simplify FIFO configuration code

The FIFO registers base address is different in dm646x compared to newer
SoCs with McASP IP. Instead of using two paths (switch/case) to handle the
difference we can simply pick the correct base address beforehand and use
offsets to address the register we need to configure.
With this change the indentation depth can be reduced as well.

Subject: ASoC: davinci-mcasp: Data source (bus) selection support

The audio data to/from McASP can be sent/received via two method:
Via the data port (preferred) or via the configuration bus.
Currently the driver assumes that all data communication will be done via
the data port.
This patch adds support for selecting the configuration port as data
interface.

Subject: ASoC: davinci-mcasp: Support for McASP version found in DRA7xx

The IP in DRA7xx is similar to the IP found in TI81xxAM3xxx/AM4xxx type of
SoCs but it is is integrated with sDMA instead of eDMA. The suitable pcm
driver for DRA7xx is the omap-pcm driver which is using dmaengine.
In the driver we can configure both dma related structures used for eDMA and
sDMA. The only thing we need to make sure that we set the correct dma_data
at startup with snd_soc_dai_set_dma_data()

Subject: ASoC: davinci-mcasp: Change IO functions parameter list

Instead of passing __iomem address (mcasp->base + register_offset) pass
the main mcasp structure and only access the mcasp->base in the low level
IO functions.
In most cases this helps with code readability and it will make it easier
to switch over to regmap in the future.

An earlier patch overlooked this when the compatible has been changed from
omap2 -> am33x.
Rename omap2_mcasp_pdata to am33xx_mcasp_pdata.

Subject: ALSA: at73c213: clk_round_rate() can return a zero upon error

Treat both negative and zero return values from clk_round_rate()
as errors.  This is needed since subsequent patches will convert
clk_round_rate()'s return value to be an unsigned type, rather
than a signed type, since some clock sources can generate rates higher
than (2^31)-1 Hz.

Eventually, when calling clk_round_rate(), only a return value of
zero will be considered a error.  All other values will be
considered valid rates.  The comparison against values less than
0 is kept to preserve the correct behavior in the meantime.

Subject: ASoC: dmaengine: support deferred probe for DMA channels

Enhance dmaengine_pcm_request_chan_of() to support deferred probe for
DMA channels, by using the new dma_request_slave_channel_or_err() API.
This prevents snd_dmaengine_pcm_register() from succeeding without
acquiring DMA channels due to the relevant DMA controller not yet being
registered.

In preparation for using the dmaengine helpers in ASoC rather than the
dmaengine wrappers for the Samsung API wrap the configuration of dma_data.
The dmaengine code expects different data to that used by the legacy API.

Subject: ASoC: samsung: Use ASoC dmaengine code where possible

Since all Exynos platforms have been converted to dmaengine and many of
the older platforms are in the process of conversion they do not need to
use the legacy s3c-dma APIs for DMA but can instead use the standard ASoC
dmaengine helpers. This both allows them to benefit from improvements
implemented in the generic code and supports multiplatform.

This patch includes some fixes from Padma for Exynos SoCs, her testing
was on a slightly earlier version of the patch due to unrelated breakage
preventing testing.

When writing the patch write to the device asynchronously, allowing better

Subject: ASoC: fsl/mxs: Remove unnecessarily gendered language

The kernel as a number of cases of gendered language. The majority of these
refer to objects that don't have gender in English, and so I've replaced
them with "it" and "its". Some refer to people (developers or users), and
I've replaced these with the singular "they" variant. Some are simply
typos that I've fixed up.

I've left cases where gendered language was used to refer to specific
individuals, was a quote or is part of license text.

From 11db0da831b1e6ae3c1f8743599434281db294db Mon Sep 17 00:00:00 2001
From: Shawn Guo <shawn.guo@linaro.org>

Subject: ASoC: sgtl5000: clean up sgtl5000_enable_regulators()

Function sgtl5000_enable_regulators() is somehow odd in handling the
optional external VDDD supply.  The driver can only enable this supply
on SGTL5000 chip before revision 0x11, and of course when this external
VDDD is present.  It currently does something like below.

1. Check if regulator_bulk_get() on VDDA, VDDIO and VDDD will fail.  If
   it fails, VDDD must be absent and it falls on internal LDO by calling
   sgtl5000_replace_vddd_with_ldo().  Otherwise, VDDD is used.  And in
   either case, regulator_bulk_enable() will be called to enable
   3 supplies.

2. In case that SGTL5000 revision is later than 0x11, even if external
   VDDD is present, it has to roll back the 'enable' and 'get' calls
   with regulator_bulk_disable() and regulator_bulk_free(), and starts
   over again by calling sgtl5000_replace_vddd_with_ldo() and
   regulator_bulk_enable().

Such back and forth calls sequence is complicated and unnecessary.
Also, since commit 4ddfebd (regulator: core: Provide a dummy regulator
with full constraints), regulator_bulk_get() will always succeeds
because of the dummy regulator.  Thus the VDDD detection is broken.

The patch changes the flow to something like the following, which should
be more reasonable and clear, and also fix the VDDD detection breakage.

1. Check if we're running a chip before revision 0x11, on which an
   external VDDD can possibly be an option.

2. If it is an early revision, call regulator_get_optional() to detect
   whether an external VDDD supply is available.

3. If external VDDD is present, call sgtl5000_replace_vddd_with_ldo() to
   update sgtl5000->supplies info.

4. Drop regulator_bulk_get() call in sgtl5000_replace_vddd_with_ldo(),
   and call it in sgtl5000_enable_regulators() no matter it's an
   external VDDD or internal LDO.

5. Call regulator_bulk_enable() to enable these 3 regulators.

Subject: ASoC: ep93xx: get rid of ep93xx-pcm-audio struct device

Modify the ep93xx PCM driver so that it's a utility library that can be
registered on each DAI, rather than a separate struct device. This is
more in line with how many recent DT-converted platforms operate, and
avoids the need for yet another struct device.

Subject: ASoC: ep93xx: remove custom DMA alloc compat function

ep93xx_compat_request_channel() is almost identical to
dmaengine_pcm_compat_request_channel(), with the exception that the
latter:

a) Assumes that the DAI DMA data is a struct snd_dmaengine_dai_dma_data
   pointer rather than some custom type.

b) dma_data->filter_data rather than dma_data should be passed to
   snd_dmaengine_pcm_request_channel() as the filter data.

Make minor changes to the ep93xx DAI drivers so that those two conditions
are met. This allows removal of the custom .compat_request_channel().

Subject: ASoC: SPEAr: get rid of spear-pcm-audio struct device

Modify the SPEAr PCM driver so that it's a utility library that can be
registered on each DAI, rather than a separate struct device. This is
more in line with how many recent DT-converted platforms operate, and
avoids the need for yet another struct device.

This is also required as a pre-cursor to removing
spear_pcm_request_chan().

Subject: ALSA: hda - Make CONFIG_SND_HDA_CODEC_* tristate

So far, CONFIG_SND_HDA_CODEC_* kconfigs have been booleans due to
historical reasons.  The major reason was that the automatic codec
driver probing wouldn't work if user sets a codec driver as a module
while the controller driver as a built-in.  And, another reason was to
avoid exporting symbols of the helper codes when all drivers are built
in.

But, this sort of "kindness" rather confuses people in the end,
especially makes the config refinement via localmodconfig unhappy.
Also, a codec module would still work if you re-bind the controller
driver via sysfs (although it's no automatic loading), so there might
be a slight use case.

That said, better to let people fallen into a pitfall than being too
smart and restrict something.  Let's make things straightforward: now
all CONFIG_SND_HDA_CODEC_* become tristate, and all symbols exported
unconditionally.

From d8f66c71d547538e1c61622139455dd231238aef Mon Sep 17 00:00:00 2001
From: Takashi Iwai <tiwai@suse.de>

Subject: ALSA: hda - Add warning texts when codec driver Kconfig doesn't match

When a Kconfig of a codec driver doesn't match with the controller
(CONFIG_SND_HDA_INTEL), it'll result in the non-working automatic
probing.  Unfortunately kbuild can't give such a restriction, but at
least, it's possible to show a warning if such a condition is found.

Subject: ASoC: fsl/mxs: Remove unnecessarily gendered language

The kernel as a number of cases of gendered language. The majority of these
refer to objects that don't have gender in English, and so I've replaced
them with "it" and "its". Some refer to people (developers or users), and
I've replaced these with the singular "they" variant. Some are simply
typos that I've fixed up.

I've left cases where gendered language was used to refer to specific
individuals, was a quote or is part of license text.

Subject: ASoC: fsl_ssi: Add DAI master mode support for SSI on i.MX series

This patch adds three main functions for DAI master mode: set_dai_fmt(),
set_dai_sysclk() and set_dai_tdm_slot(), and one essential baud clock
accordingly. After appending this patch, the fsl_ssi driver on i.MX series
has the ability to derive LRCLK and BCLK from baud clock source so as to
support some audio Codecs which can only be used in slave mode.

Subject: ASoC: twl6040: Custom caching for sensitive DL1/2 path registers

Introduce a small register cache for registers which needs special caching
to reduce pop noise:
TWL6040_REG_HSLCTL, TWL6040_REG_HSRCTL, TWL6040_REG_EARCTL, TWL6040_REG_HFLCTL
and TWL6040_REG_HFRCTL.
Switch over and use the new small cache for these registers instead of the
main reg_cache.
This is in preparation to remove the local ASoC reg_cache from the driver.

Subject: ASoC: twl6040: Remove self managed local reg_cache support

We can rely on mfd driver to manage the register caching via regmap. The
driver still need to cache some registers associated with DL1/2 routes.

Subject: ALSA: hda - Fix wrong <acpi/acpi.h> inclusion in Thinkpad ACPI users.

CONFIG_ACPI dependent code should include <linux/acpi.h> instead of
directly including <acpi/acpi.h>.  This patch cleans up such wrong
inclusions for Thinkpad ACPI users.

Subject: ALSA: hda - Enable subwoofer on Dell Vostro 5460/5470

In this case, there are two DACs, and DAC 0x03 is mono. In order
to make headphones and front speaker use DAC 0x02, and subwoofer use
DAC 0x03, we artificially cut the connection from nodes 0x14 and 0x15
to node 0x03, so they can only use DAC 0x02.

In addition, the 5460 and 5470 differs in the sense that 5470 also
needs a headset mic patch, whereas 5460 has individual detection for
headphone and headset mic.

Subject: ALSA: usb-audio: Add a quirk for Plantronics Gamecom 780

Plantronics Gamecom 780 headset has a firmware problem, and when the
FU 0x09 volume is changed, it results in either too loud or silence
except for a very narrow range.  This patch provides a workaround,
ignoring the node, initialize the volume in a sane value and keep
untouched.

Subject: ASoC: au1x: Don't set unused struct snd_pcm_hardware fields

The ASoC core assumes that the PCM component of the ASoC card transparently

the transfer speed. It ignores all fields from the snd_pcm_hardware struct for
the PCM driver that are related to this. Setting these fields in the PCM driver
might suggest otherwise though, so rather not set them.

Subject: ASoC: fsl_sai: Sort local variable in general way

Generally we would write code for local variable like:
static new_func()
{
	struct xxx *yyy;
	...
	int ret;
}

But this driver only follows this pattern for some functions, not all.
Thus this patch sorts the local variable in the general way.

Subject: ASoC: blackfin: Don't set unused struct snd_pcm_hardware fields

The ASoC core assumes that the PCM component of the ASoC card transparently
moves data around and does not impose any restrictions on the memory layout or
the transfer speed. It ignores all fields from the snd_pcm_hardware struct for
the PCM driver that are related to this. Setting these fields in the PCM driver
might suggest otherwise though, so rather not set them.

Subject: ASoC: fsl_sai: Move the global registers setting to _dai_probe()

Because we cannot make sure which one of _dai_fmt() and _dai_sysclk()
will be firstly called. So move the RCSR/TCSR and TCR1/RCR1's
initialization to _dai_probe(), and this can make sure that before any
of {T,R}CR{1~5} register to be set the RCSR/TCSR's RE/TE bit has been
cleared for the hareware limitation.

the transfer speed. It ignores all fields from the snd_pcm_hardware struct for
the PCM driver that are related to this. Setting these fields in the PCM driver
might suggest otherwise though, so rather not set them.

Subject: ASoC: fsl_sai: Fix one bug for hardware limitation.

This is maybe one bug or a limitation of the hardware that the {T,R}CR2's
Synchronous Mode bits must be set as late as possible, or the SAI device
maybe hanged up, and there has not any explaination about this limitation
in the SAI Data Sheet.

And the {T,R}CR2's Synchronous Mode bits must be set at the same time whether
for Tx or Rx stream.

Subject: ASoC: rsnd: route setting is needed only Gen1

Renesas sound has SRC (= Sampling Rate Converter),
but, the HW implementation depends on its generation.
It was part of SRU on Gen1, and SCU on Gen2.
This SCU needs DMA transfer to use it.
Current rsnd driver is using it as DMA transfer buffer
(= no rate convert), and Gen1 is only supported at this point.

This patch cleanup it with focusing about SRC and Gen2 part.

rsnd_scu_set_route() is needed only Gen1.

This patch renames it to rsnd_scu_set_route_if_gen1()
and it adds comment to rsnd_reg member
in order to clarify it is used for Gen1.

Subject: ASoC: rsnd: tidyup rsnd_ssi_master_clk_start() parameter

Renesas sound has SRC (= Sampling Rate Converter),
but, the HW implementation depends on its generation.
It was part of SRU on Gen1, and SCU on Gen2.
This SCU needs DMA transfer to use it.
Current rsnd driver is using it as DMA transfer buffer
(= no rate convert), and Gen1 is only supported at this point.

This patch cleanup it with focusing about SRC and Gen2 part.

ssi clock which is calculated from rsnd_ssi_master_clk_start()
should have flexibility since Renesas sound has
SRC (= Sampling Rate Converter).
But current implementation is using runtime->rate directly.
This patch tidyup rsnd_ssi_master_clk_start() parameter
as preparation of future SRC support

Subject: ASoC: rsnd: add SRC (Sampling Rate Converter) support

This patch adds SRC support to Renesas sound driver.
SRC converts sampling rate between codec <-> cpu.
It needs special codec chip,
or very simple DA/AD converter to use it.
This patch was tested via ak4554 codec,
and supports Gen1 only at this point.

Subject: ASoC: core: Fix the DAI name getting.

From "ASoC: make snd_soc_dai_link more symmetrical", can we see that
the name of CPU DAI maybe omitted. If the DAI name is omitted, try to
use the component name instead.

Subject: ASoC: imx-spdif: Use snd-soc-dummy CODEC driver to link card

This is a quick fix for the below two issues when building spdif as modules.

1) If modprobing modules in order: (Step 1) snd-soc-fsl-spdif -> (Step 2)
snd-soc-imx-spdif -> (Step 3) snd-soc-spdif-tx/rx, we will fail to create
imx-spdif card and dai link unless we rmmod snd-soc-imx-spdif and modprobe
it again due to the execution platform_driver_unregister() in probe() when
meeting -EPROBE_DEFER at Step 2.

2) After "imx-spdif sound-spdif.17: dit-hifi <-> 2004000.spdif mapping ok",
'rmmod snd-soc-imx-spdif' would cause kernel dump with warning:
WARNING: CPU: 0 PID: 1301 at /home/rmk/git/linux-rmk/fs/sysfs/dir.c:915 sysfs_hash_and_remove+0x84/0x90()
sysfs: can not remove 'dapm_widget', no directory
This should be caused by disordered resourse releasing of the whole link.
And trying to unregister the card and then CODEC dev can't fix this issue.

Thus this patch just provides a simple fix to these two bugs by using the
snd-soc-dummy in the core instead of seperate snd-soc-spdif-tx/rx so that
there's no need to handle the registering and unregistering of CODEC or
CODEC dai any more.

ffs() returns the bit position from 1, while the ssm2158 driver code
assumes it being 0-based.  Also, the bit mask computation of the two
channel slots are incorrect; it must have worked just casually.

This motherboard seems to have a flaky jack detection - when the

This has been reported by three people in the bug, so I doubt it's
a user error this time.

The ASoC core assumes that the PCM component of the ASoC card transparently

the transfer speed. It ignores all fields from the snd_pcm_hardware struct for
the PCM driver that are related to this. Setting these fields in the PCM driver
might suggest otherwise though, so rather not set them.

Subject: ASoC: dpcm: Allow PCMs to omit the set of supported formats

Allow PCMs that do not impose any restrictions on the supported formats to set
the formats field to 0, Instead of assuming that this means that the PCM does
not support any formats (which doesn't make much sense), assume that it supports
all formats. This brings the behavior of DPCM closer to that of non-DPCM.

Subject: ASoC: mxs: Don't set unused struct snd_pcm_hardware fields

The ASoC core assumes that the PCM component of the ASoC card transparently
moves data around and does not impose any restrictions on the memory layout or
the transfer speed. It ignores all fields from the snd_pcm_hardware struct for
the PCM driver that are related to this. Setting these fields in the PCM driver
might suggest otherwise though, so rather not set them.

Subject: ASoC: mxs: Remove SND_DMAENGINE_PCM_FLAG_NO_RESIDUE flag

Since commit 7b11304 ("dma: mxs-dma: Report correct residue for cyclic DMA")
the mxs dmaengine driver has support for residue reporting. So there is no need
to specify the SND_DMAENGINE_PCM_FLAG_NO_RESIDUE flag anymore. This allows a
finer grained resolution for the PCM pointer as well as avoids the race
condition that can occur with the period counting that is used when the
dmaengine driver does not support residue reporting.

The Slave Config's addr_width attribute is populated by data_width of

We're cutting out the middle man here and just setting the DMA Slave

Subject: ASoC: ux500_pcm: Expect different saved DMA data when obtaining from
 DAI store

In preparation for full Device Tree enablement we must differentiate
between the two varying ways DMA data can be held in the DAI store. If
we're booting with Device Tree the provided 'snd_dmaengine_dai_dma_data'
data structure shall be used, whereas in order to avoid breaking legacy
platform data we also need to be able to translate DMA data stored using
the UX500 specific 'ux500_msp_dma_params' method.

Once we move over to solely use Device Tree, we can enforce the use of
'snd_dmaengine_dai_dma_data' and this code can be removed altogether.

Subject: ASoC: ux500_pcm: Extend Device Tree support to deal with DMA data

Soon we will strip out pdata support from the Ux500 set of ASoC drivers.
When this happens it will have to supply a DMA slave_config to the
dmaengine. At the moment a great deal of this comes from pdata via
AUXDATA. We need to become independent of this soon. This patch starts
the process by allocating memory for the associated data structures and
fetches the MSP id used for const struct indexing.

Subject: ASoC: ux500: Store DMA data in the DAI differently in the pdata and
 DT case

In this patch we do two things. Firstly, instead of open coding the
store of DMA data in to the DAI for later use, we use the API provided.
Secondly we create and store similar DMA data for the DT case, only
this time we use 'struct snd_dmaengine_dai_dma_data' which is provided
by the core for this very reason.

Subject: ASoC: ux500_pcm: Differentiate between pdata and DT initialisation

If booting with full DT support (i.e. DMA too, the last piece of the
puzzle), then we don't need to use the compatible_request_channel call
back or require some of the historical bumph which probably isn't
required by a platform data start-up now either. This will also be
ripped out in upcoming commits.

Subject: ASoC: ux500: Dramatically reduce the size of the DAI driver data
 struct

We no longer have a means to differentiate between MSP devices at probe
time, mainly because we don't really have to. So rather than have an over-
sized static data structure in place, where the only difference between
devices is the ID and name (which are unused), we'll just create one
succinct, statically assigned and shared one instead.

Subject: ALSA: hda - Increment default stream numbers for AMD HDMI controllers

It turned out that some AMD HDMI controllers still don't provide
proper values in GCAP register (all zero), and the driver assigns only
one stream in that case, although the connected codec chip supports
more than one stream.

In this patch, the default max number of streams for AMD HDMI
controllers is increased to 8, which  should suffice for most use
cases.  The overhead by this increase is more azx_dev struct and BDL
allocations, so it's negligible.  Of course, if the controller
provides a proper GCAP register, the register value would be used.

Subject: ALSA: hda - Add consistent tag names for firmware patch

Some tags used in the firmware patch file are inconsistent with hwdep
sysfs file names, such as, the firmware patch takes [hint] tag while
sysfs file is */hints.  This makes even me referring back to the
document often.  Let's provide the same tag names as sysfs for
reducing confusions.

Subject: ALSA: hda - Don't create duplicated ctls for loopback paths

AD1986A mic pins (0x1d and 0x1f) share the same widget for controlling
the loopback volume/mute, but the generic parser didn't check it.
This ended up with the duplicated controls for the same effect.

This patch adds the check of the duplication for avoiding it.

After this fix, there will be only one control although it affects
both paths; this remaining issue should be fixed later in a different
patch.

Subject: ASoC: twl4030: Remove reset registers functionality

The register states now tracked by the regmap implementation in the core which
makes the reset registers functionality 'redundant' since we know the state
of the registers now all the time.

Subject: ASoC: twl4030: Introduce local ctl register cache

Few registers need to be cached in the codec driver level. These registers
should only be written when the path is active to avoid pop noise on the
given path.
This patch adds an array which covers the range where the sensitive registers
are located and uppon loadinf the driver the ctl cache will be initialized.

Subject: ASoC: twl4030: Remove local reg cache

Depend on the regmap reg cache implementation for register caching done in
the twl-core driver.
The local register cache can be removed and we can keep only shadow copies
of certain ctl registers for pop noise reduction.

From 7ded5fe020e670befeab6777e7b8bc4bec272a3f Mon Sep 17 00:00:00 2001
From: Peter Ujfalusi <peter.ujfalusi@ti.com>
Date: Fri, 3 Jan 2014 15:27:54 +0200
Subject: ASoC: twl4030: Parameter alignment fixes (for code consistency)

Over time the multi line alignment got messed up. Correct them in one go
so the code will look consistent.

Subject: ALSA: hda - Split Thinkpad ACPI-related code

Both patch_realtek.c and patch_conexant.c contain the fairy same code
snippet for supporting Thinkpad ACPI LED controls.  Split them into
thinkpad_helper.c and include it from both places.  Although this
isn't the best approach from the code size POV, the probability for
coexistence of both Realtek and Conexant codecs on a single machine is
pretty low, thus it'll end up with less memory footprint than
splitting to yet another module.

Subject: ASoC: fsl-ssi: Move sysfs stats to debugfs

Interrupt statistics of fsl_ssi are mainly for debugging purpose. Most
of those interrupts show error states, e.g. under/overflow.
The stats should be exposed via debugfs instead of sysfs.

This patch moves the statistics file to debugfs.

Subject: ASoC: fsl-ssi: Add imx51-ssi and of_device_id matching

There is a small but significant difference between imx21-ssi and
imx51-ssi and above. imx21-ssi does not allow online reconfiguration of
some registers. They have to be configured at the beginning.

imx51-ssi has to reconfigure the SSI unit while it is running. Otherwise
it would not be possible to have two streams in parallel. The new SDMA
unit in imx51 and above has to be configured before the first DMA
request arrives. Therefor we need to setup TDMAE/RDMAE just before
starting the stream.

This patch introduces distinct imx51-ssi as compatible and adds
of_device_id matching in the probe function.

Subject: ASoC: fsl-ssi: Fix interrupt stats for imx

irqs should only be requested/released with enabled DMA. Previously
interrupt statistics where disabled for IMX Processors because of
different writeable SISR bits.

This patch introduces support for irqstats on imx processors again by
creating a sisr writeback mask and introducing a imx35-ssi compatible.

Subject: ASoC: fsl-ssi: Add offline_config flag

imx50-ssi and later versions of this IP support online reconfiguration
of all registers. The reference manual does not list any registers that
can only be configured while the SSI unit is disabled. This patch
introduces the flag for later use.

Subject: ASoC: fsl-ssi: Add configuration helper functions

This patch adds a struct 'fsl_ssi_rxtx_reg_val' which holds register
values necessary to enable rx/tx. Based on those preset register values,
the added configuration functions will cleanly enable/disable different
parts of the SSI IP while supporting online/offline configuration.
Different operating modes can be setup directly as different register
values in fsl_ssi_reg_val.

These functions and structs will help to cleanup and simplify the
trigger function to support many different IP versions (online/offline
configuration) and different operating modes.

Subject: ASoC: fsl-ssi: Move RX/TX configuration to seperate functions

This patch defines the appropriate register values for different
oparation modes and IP versions. We have to handle DMA/FIQ, AC97,
DEBUG-IRQs and offline/online configuration support.

With this patch we cleanup some driver code that was not reference
manual conform and try to cleanup the whole trigger function to seperate
the actual register values from the enable/disable logic, which is now
hidden in fsl_ssi_config helpers.

Subject: ASoC: wm_adsp: Start DSP booting earlier in the DAPM process

Move the start of booting the DSP to earlier in the DAPM process, and
move the final starting of the DSP to later in the DAPM process. This
allows us to overlap some of the processing with other components of the
system being brought up.

Subject: ASoC: bcm: Remove obsoleted Kconfig dependency

CONFIG_SND_SOC_DMAENGINE_PCM was renamed to CONFIG_SND_DMAENGINE_PCM
recently.  And yet we don't have to select it since
CONFIG_SND_GENERIC_DMAENGINE_PCM selects the dependency by itself, so
just rip it off.

Subject: ALSA: hda/hdmi - apply all Haswell fix-ups to Broadwell display codec

Broadwell and Haswell have the same behavior on display audio. So this patch
defines is_haswell_plus() to include codecs for both Haswell and its successor
Broadwell, and apply all Haswell fix-ups to Broadwell.

Subject: ALSA: Remove memory reservation code from memalloc helper

Nowadays we have CMA for obtaining the contiguous memory pages
efficiently.  Let's kill the old kludge for reserving the memory pages
for large buffers.  It was rarely useful (only for preserving pages
among module reloading or a little help by an early boot scripting),
used only by a couple of drivers, and yet it gives too much ugliness
than its benefit.

Instead of keeping a separate snd-page-alloc module, merge into the
core snd-pcm module, as we don't need to keep it as an individual
module due to the drop of page reservation.

Subject: ASoC: Allow PCMs to restrict the supported formats

Some DMA cores might add additional restrictions on which in memory audio
formats can be supported by the compound sound card. If the PCM component
specifies a set of formats it supports (by setting the formats field to non 0)
take these into account when calculating the format set for the compound sound
card.

Subject: ALSA: ctxfi - Work around emu20k1 glitch to prevent buffered sound
 data loss

Occasionally, on playback stream ringbuffer wraparound, the EMU20K1
hardware will momentarily return 0 instead of the proper current(loop)
address. This patch handles that case, fixing the problem of playback
position corruption and subsequent loss of buffered sound data, that
occurs with some common buffering layout patterns(e.g. multiple
simultaneous output streams with differently-sized or
non-power-of-2-sized buffers).

An alternate means of fixing the problem would be to read the ca
register continuously, until two sequential reads return the same
value; however, that would be a more invasive change, has performance
implications, and isn't necessary unless there are also issues with the
value not being updated atomically in regards to individual bits or
something similar(which I have not encountered through light testing).

I have no EMU20K2 hardware to confirm if the issue is present there,
but even if it's not, this change shouldn't break anything that's not
already broken.

Subject: ASoC: fsl_esai: Add ESAI CPU DAI driver

This patch implements a device-tree-only CPU DAI driver for Freescale ESAI
controller that supports:

 - 12 channels playback and 8 channels record.
   [ Some of the inner transmitters and receivers are sharing same group of
     pins. So the maxmium 12 output or 8 input channels are only valid if
     there is no pin conflict occurring to it. ]

 - Independent (asynchronous mode) or shared (synchronous mode) transmit and
   receive sections with separate or shared internal/external clocks and frame
   syncs, operating in Master or Slave mode.
   [ Current ALSA seems not to allow CPU DAI drivers to configure DAI format
     separately for PLAYBACK and CAPTURE. So this first version only supports
     the case that uses the same DAI format for both directions. ]

 - Various DAI formats: I2S, Left-Justified, Right-Justified, DSP-A and DSP-B.

 - Programmable word length (8, 16, 20 or 24bits)

 - Flexible selection between system clock or external oscillator as input
   clock source, programmable internal clock divider and frame sync generation.

Subject: ALSA: PCM: Warn when buffer preallocation fails

The failures of buffer preallocations at driver initializations aren't
critical but it's still helpful to inform, so that user can know that
something doesn't work as expected.

For example, the recent page allocator change triggered regressions,
but developers didn't notice until recently because the driver didn't
complain.

Subject: ALSA: Enable CONFIG_ZONE_DMA for smaller PCI DMA masks

The PCI devices with DMA masks smaller than 32bit should enable
CONFIG_ZONE_DMA.  Since the recent change of page allocator, page
allocations via dma_alloc_coherent() with the limited DMA mask bits
may fail more frequently, ended up with no available buffers, when
CONFIG_ZONE_DMA isn't enabled.  With CONFIG_ZONE_DMA, the system has
much more chance to obtain such pages.

From cbd209f41ea5f39394de5c1fe2dd9aa54a9c5744 Mon Sep 17 00:00:00 2001
From: Takashi Iwai <tiwai@suse.de>
Date: Mon, 13 Jan 2014 12:40:07 +0100
Subject: ALSA: hda - Don't set indep_hp flag for old AD codecs

Some old AD codecs don't like the independent HP handling, either it
contains a single DAC (AD1981) or it mandates the mixer routing
(AD1986A).  This patch removes the indep_hp flag for such codecs.

Subject: ALSA: hda - automute via amp instead of pinctl on some AIO models

On some AIO (All In One) models with the codec alc668
(Vendor ID: 0x10ec0668) on it, when we plug a headphone into the jack,
the system will switch the output to headphone and set the speaker to
automute as well as change the speaker Pin-ctls from 0x40 to 0x00,
this will bring loud noise to the headphone.

I tried to disable the corresponding EAPD, but it did not help to
eliminate the noise.

According to Takashi's suggestion, we use amp operation to replace the
pinctl modification for the automute, this really eliminate the noise.

Subject: ALSA: usb-audio: Fix Creative VF0420 rate

Creative Live! Cam Vista IM (VF0420) reports rate of 16kHz while working
at 8kHz. The patch adds its USB ID to the existing quirk.

Subject: ALSA: hda - Fix endless vmaster hook call in thinkpad_helper.c

The new vmaster hook, update_tpacpi_mute_led(), calls the original
vmaster hook, but I forgot to save the original hook function but keep
calling the updated one, which of course results in a stupid endless
loop.  Fixed now.

Subject: sound: oss: msnd_pinnacle: avoid interruptible_sleep_on_timeout

We want to remove all sleep_on variants from the kernel because they are
racy. In case of the pinnacle driver, we can replace
interruptible_sleep_on_timeout with wait_event_interruptible_timeout
by changing the meaning of a few flags used in the driver so they
are cleared at wakeup time, which is a somewhat more appropriate
way to do the same, although probably still racy.

Subject: sound: oss: vwsnd: avoid interruptible_sleep_on

Interruptible_sleep_on is racy and we want to remove it. This replaces
the use in the vwsnd driver with an open-coded prepare_to_wait
loop that fixes the race between concurrent open() and close() calls,
and also drops the global mutex while waiting here, which restores
the original behavior that was changed during the BKL removal.

Subject: sound: oss: midibuf: fix sleep_on races

sleep_on is known to be racy and going away because of this. All instances
of interruptible_sleep_on and interruptible_sleep_on_timeout in the midibuf
driver can trivially be replaced with wait_event_interruptible and
wait_event_interruptible_timeout.

Subject: sound: oss: dmasound: kill SLEEP() macro to avoid race

The use of interruptible_sleep_on_timeout in the dmasound driver
is questionable and we want to kill off all sleep_on variants.
This replaces the calls with wait_event_interruptible_timeout
where possible, to wait for a particular event instead of blocking
in a racy way. In the sq_write function, the easiest solution is
an open-coded prepare_to_wait loop.

Subject: sound: oss: remove last sleep_on users

There are three files in oss for which I could not find an easy way to
replace interruptible_sleep_on_timeout with a non-racy version. This
patch instead just adds a private implementation of the function, now
named oss_broken_sleep_on, and changes over the remaining users in
sound/oss/ so we can remove the global interface.

Subject: ASoC: pcm: Properly initialize hw->rate_max

If none of the components (CODEC or CPU DAI) sets a maximum sample rate we'll
end up with the rate_max field of the runtime hardware set to 0.  (Note that it
is still possible for the components to constrain the supported sample rates
using other methods, e.g. setting a list constraint) If rate_max is 0 this means
that the sound card doesn't support any rates at all, which is not the desired
result. So initialize rate_max to UINT_MAX. For symmetry reasons also set
rate_min to 0.

Subject: ALSA: Add helper function for intersecting two rate masks

A bit of special care is necessary when creating the intersection of two rate
masks. This comes from the special meaning of the SNDRV_PCM_RATE_CONTINUOUS and
SNDRV_PCM_RATE_KNOT bits, which needs special handling when intersecting two
rate masks. SNDRV_PCM_RATE_CONTINUOUS means the hardware supports all rates in a
specific interval. SNDRV_PCM_RATE_KNOT means the hardware supports a set of
discrete rates specified by a list constraint. For all other cases the supported
rates are specified directly in the rate mask.

Subject: ASoC: generic-dmaengine-pcm: Check NO_RESIDUE flag at runtime

Currently we have two different snd_soc_platform_driver structs in the generic
dmaengine PCM driver. One for dmaengine drivers that support residue reporting
and one for those which do not. When registering the PCM component we check
whether the NO_RESIDUE flag is set or not and use the corresponding
snd_soc_platform_driver. This patch modifies the driver to only have one
snd_soc_platform_driver struct where the pointer() callback checks the
NO_RESIDUE flag at runtime. This allows us to set the NO_RESIDUE flag after the
PCM component has been registered. This becomes necessary when querying whether
the dmaengine driver supports residue reporting from the dmaengine driver itself
since the DMA channel might only be requested after the PCM component has been
registered.

The dmaengine framework now exposes the granularity with which it is able to
report the transfer residue for a certain DMA channel. Check the granularity in
the generic dmaengine PCM driver and
	a) Set the SNDRV_PCM_INFO_BATCH if the granularity is per period or worse.
	b) Fallback to the (race condition prone) period counting if the driver does
	not support any residue reporting.

The pl330 driver properly reports that it does not have residue reporting
support, which means the PCM dmanegine driver is able to figure this out on its
own. So there is no need to set the flag manually. Removing the flag has the
advantage that once the pl330 driver gains support for residue reporting it will
automatically be used by the generic dmaengine PCM driver.

Subject: ASoC: samsung: Remove SND_DMAENGINE_PCM_FLAG_NO_RESIDUE flag

The Samsung dmaengine ASoC driver is used with two different dmaengine drivers.
The pl80x, which properly supports residue reporting and the pl330, which
reports that it does not support residue reporting. So there is no need to
manually set the NO_RESIDUE flag. This has the advantage that a proper (race
condition free) PCM pointer() implementation is used when the pl80x driver is
used. Also once the pl330 driver supports residue reporting the ASoC PCM driver
will automatically start using it.

Subject: ASoC: core: Return -ENOTSUPP from set_sysclk() if no operation
 provided

Make it easier for generic code to work with set_sysclk() by distinguishing
between the operation not being supported and an error as is done for
other operations like set_dai_fmt()

Subject: ALSA: hda - add headset mic detect quirks for some Dell machines

When we plug a 3-ring headset on some Dell machines, the headset
mic can't be detected, after apply this patch, the headset mic
can work well on all those machines.

On the machine with the Subsytem ID 0x10280610, if we use
ALC269_FIXUP_DELL1_MIC_NO_PRESENCE, the headset mic can be
detected and work well, but the sound can't be outputed via
headphone anymore, use ALC269_FIXUP_DELL3_MIC_NO_PRESENCE
can fix this problem.
