2263fddcd0 ASoC: nau8825: lock longer to avoid playback pop upon resume
There is an issue about pop noise in NAU88L25 as follows.
Issue 54078: Chell_headphone pop back from S3
(1)Play directly to hw, bypassing CRAS:
sox -b 16 -n -t alsa hw:0,0 synth sine 200 sine 200
(2)Close lid or powerd_dbus_suspend, then press a key to resume.
(3)no audio after resume
(4)Audio will be back after close then reopen the pcm device.

After verification, we find one defect is that semaphone lock is not
long enough and expired. In this situation, the playback comes back
early but pauses a while to wait for the crosstalk detection done.
But the detection spends too much time and lock time is up. Therefore,
the playback and jack detection sequence interfere to each other.
That breaks sequence and makes noise. The driver extends the lock
time for the issue.

While in the replacement, move the schedule_work() call inside the

35f4403edb ASoC: arizona: Use component pin control functions
We need to modify the state of some of our own pins and are currently
not taking account that the pin name may have a name_prefix applied
to it.

Replace the snd_soc_dapm_x_pin functions with the equivalent
snd_soc_component_x_pin functions so that any name_prefix will be
handled automatically.

1b4d9c2219 ASoC: core: Add component pin control functions
It's often the case that a codec driver will need to control its
own pins. However, if a name_prefix has been applied to this codec it
must be included in the name passed to any of the snd_soc_dapm_x_pin()
functions.

The behaviour of the existing pin control functions is reasonable, since
you may want to search for a fully-specified name within the scope of an
entire card. This means that we can't apply the prefix in these functions
because it will break card-scope searches.

Constructing a prefixed string "manually" in codec drivers leads to a lot
of repetition of the same code.

To make this tidier in codec drivers this patch adds a new set of
equivalent functions that take a struct snd_soc_component instead of a
dapm context and automatically add the component's name_prefix to the
given name. This makes it a simple change in codec drivers to be
prefix-safe.

The new functions are not quite trivial enough to be inlines and the
compiler won't be able to compile-away any part of them.

Although it looks somewhat inefficient to have to allocate a temporary
buffer and combine strings, the current design of the widget list
doesn't lend itself to a more optimized implementation - it's a single
list of all widgets on a card and is searched linearly for a matching
string. As pin state changes are generally low-frequency events it's
unlikely to be a significant issue - at least not enough to rewrite the
widget list handling just for this.

16f46050e7 dbri: Fix compiler warning
dbri uses 'u32' for dma handle while invoking kernel DMA APIs,
instead of using dma_addr_t. This hasn't caused any 'incompatible
pointer type' warning on SPARC because until now dma_addr_t is of
type u32. However, recent changes in SPARC ATU (iommu) enabled 64bit
DMA and therefore dma_addr_t became of type u64. This makes
'incompatible pointer type' warnings inevitable.

e.g.
sound/sparc/dbri.c: In function ‘snd_dbri_create’:
sound/sparc/dbri.c:2538: warning: passing argument 3 of ‘dma_zalloc_coherent’ from incompatible pointer type
./include/linux/dma-mapping.h:608: note: expected ‘dma_addr_t *’ but argument is of type ‘u32 *’

For the record, dbri(sbus) driver never executes on sun4v. Therefore
even though 64bit DMA is enabled on SPARC, dbri continues to use
legacy iommu that guarantees DMA address is always in 32bit range.

This patch resolves above compiler warning.

685f51a5eb ASoC: wm_adsp: Firmware controls should be added as codec controls
We were adding firmware controls as card controls (using
snd_soc_add_codec_controls). The DSP is part of a specific codec so
we should be adding them as codec controls. Adding as codec controls
also means that if the codec has a name_prefix it will be added to
the control name, which won't happen when adding as a card control.

As that was the only use of the card pointer in struct wm_adsp it can
be removed.

For ADSP2 codecs a wm_adsp2_codec_probe() was added since the original
control handling was written, and that's the logical place to store a
pointer to the codec rather than delaying it until the codec is
powered-up.

For ADSP1 we don't use a codec_probe() stage so the codec pointer
initialization replaces the original card pointer initialization in
wm_adsp1_event().

2e57069c86 ALSA: bebob: compare whole string for model name so that readers are not confused
A modalias of 'ieee1394:ven00000D6Cmo00010060sp' hits units for M-Audio
FireWire Audiophile only. However the unit has two states relevant to
loaded firmware. Initial firmware returns 'FW Audiophile Bootloader',
while functional firmware returns 'FW Audiophile'.

ALSA bebob driver compares the units' model name to strings of 24 characters
by the first 15 characters. This is shorter way to differentiate these two
states but confusing to readers.

This commit improves the code for this point. Kernel stack is consumed more in
call of check_audiophile_booted() by a bit.

266c618d67 ASoC: intel: mfld: Make static string arrays 'const 'char * const []'
const char * const [] is the preferred type for static string arrays since
this states explicitly that the individual entries are not going to be
changed. Due to limitations in the ASoC API it was not possible to use it
for enum text arrays. Commit 87023ff74b ("ASoC: Declare const properly
for enum texts") changed this, but most drivers still use 'const char
* []' as the type for their enum text arrays.

Change these occurrences of 'static * const char * []' to 'static const
char * const []'.

The conversion was done automatically using the following coccinelle
semantic patch:
// <smpl>

identifier s;

-const char *
+const char * const
 s[] = ...;

This patch is a cleanup of EMU1010 dock probing code in emu10k1 driver
to use work instead of kthread in a loop.  The work is lighter and
easier to control than kthread, in general.

Instead of a loop with the explicit sleep, we do simply
delayed-schedule the work.  At suspend/resume callbacks, the work is
canceled and restarted, respectively.

e8c44abeab ALSA: emu10k1: Fix emu1010 dock attach check
The emu1010_firmware_thread() checks the previous dock status, but a
wrong register is recorded as the last status when the dock is plugged
in.  Usually this isn't a big issue since this value gets overwritten
by the next loop after one second.  But when a dock is unplugged
immediately after plugging, it means essentially missing undock
handling.

This patch addresses it by remembering the correct register value.

6ff1a25318 ALSA: usb-audio: Fix use-after-free of usb_device at disconnect
The usb-audio driver implements the deferred device disconnection for
the device in use.  In this mode, the disconnection callback returns
immediately while the actual ALSA card object removal happens later
when all files get closed.  As Shuah reported, this code flow,
however, leads to a use-after-free, detected by KASAN:

It's the code trying to clear drvdata of the assigned usb_device where
the usb_device itself was already released in usb_release_dev() after
the disconnect callback.

This patch fixes it by checking whether the code path is via the
disconnect callback, i.e. chip->shutdown flag is set.

In commit 022d00ee0b ("ASoC: lpass-platform: Fix broken pcm data
usage") the stream specific information initialization was broken, with
the dma channel information not being initialized if there was no
alloc_dma_channel() helper function.

Before that, the DMA channel number was implicitly initialized to zero
because the backing store was allocated with devm_kzalloc().  When the
init code was rewritten, that implicit initialization was lost, and gcc
rightfully complains about an uninitialized variable being used.

92be58106e ASoC: pxa: Make static string arrays 'const 'char * const []'
const char * const [] is the preferred type for static string arrays since
this states explicitly that the individual entries are not going to be
changed. Due to limitations in the ASoC API it was not possible to use it
for enum text arrays. Commit 87023ff74 ('ASoC: Declare const properly for
enum texts') changed this, but most drivers still use 'const char
* []' as the type for their enum text arrays.

Change these occurrences of 'static * const char * []' to 'static const
char * const []'.

The conversion was done automatically using the following coccinelle semantic

64e84305cb ASoC: Intel: detect audio routing with CHAN package
Baytrail-CR devices usually expose information in the DSDT
which can be used to auto-detect AIF1/AIF2 connections.
The CHAN package contains two integers, the first one describes
the AIF number (1: AIF1, 2: AIF2) and the second the MCLK
value (ignored in this patch)

For example the following information is found in Lenovo 100s:

Device (RTEK) {
[...]
    Name (CHAN, Package (0x02)
    {
        One,
        0x017D7840
    })

While on Asus T100TAF the package values are:

    Name (CHAN, Package (0x02)
    {
        0x02,
        0x017D7840
    })

This patch relies on the new common routine to extract
a package exposed by a device indexed with the HID value.
The CHAN package contents are queried from the machine driver
and stored in a structure.

If this auto-detection fails (missing or bad package in the
BIOS), the routing falls back to SSP0-AIF2.

Note that quirks may still be needed to support mono speakers
or microphone, but this should reduce the number of issues with
Baytrail significantly.

aee02c75a5 ASoC: nau8825: FLL parameters finetune
The driver fine-tune some parameters to improve FLL performance.
Those items have description as follow.
(1)ICTRL_LATCH: FLL DSP speed capability control
When FLL running at high frequency with long decimal number, DSP needs
to operate at high speed. FLL DSP can optimize between performance and
power consumption by ICTRL_LATCH.(111 has highest power consumption.)
The default setting can be used to reduce power.
(2)CUTOFF500: loop filter cutoff frequency at 500Khz
It will give the best FLL performance but highest power consumption
to enable the cutoff frequency. FLL Loop Filter enable to reduce FLL
output noise, especially,(DCO frequency)/(FLL input reference frequency)
is not a integer.
(3)GAIN_ERR: FLL gain error correction threshold setting
The threshold is comparison between DCO and target frequency.
The value 1111 has the most sensitive threshold, that is, 1111 can have
the most accurate DCO to target frequency. However, the gain error setting
conditionally and inversely depends on FLL input reference clock rate.
Higher FLL reference input frequency can only set lower gain error, such
as 0000 for input reference from MCLK=12.288Mhz. On the other side, if FLL
reference input is from Frame Sync, 48KHz, higher error gain can apply
such as 1111.

d6d197458b ASoC: nau8825: AD/DA over sampling rate configuration
Over Sampling Rate (OSR) is defined as CLK_ADC frequency divided by the
audio sample rate (Fs).
OSR = CLK_ADC / FS
The available OSRs are 32, 64, 128 or 256. Note that the OSR and Fs
values must be selected such that the maximum frequency of CLK_ADC
is less than 6.144 MHz. It is recommended to match the relationship
between OSR and clock SRC according to following Table.
ADC_RATE: 00(OSR=32)  | CLK_ADC_SRC: 11(CODEC 1/8)
ADC_RATE: 01(OSR=64)  | CLK_ADC_SRC: 10(CODEC1/4)
ADC_RATE: 10(OSR=128) | CLK_ADC_SRC: 01(CODEC 1/2)
ADC_RATE: 11(OSR=256) | CLK_ADC_SRC: 00(CODEC CLK)

The over sampling rate about DAC follows the same rule with ADCs.
The driver changes the OSR to 64 value when initiation for better FLL
performance and applies the dynamic SRC change by different OSR.

If the short Frame Sync detection logic enabled, the logic will check the
short frame sync threshold. If frame sync is less than the setting;
for example, frame sync less than 252 MCLK, the short frame sync signal is
flagged, digital filter temporary mute and skip that data.

If the system was intended for sampling rate change which could create
temporary short frame sync and not enough MIPS to run the digital filter.
But the situation doesn't happen in ALSA architecure. Thus the Frame Sync
is always stable, then no require to do the detection. Therefore,
the dirver disables the function for better performance.

The commit [1a3f099101: ALSA: hda - Fix surround output pins for
ASRock B150M mobo] introduced a fixup of pin configs for ASRock
mobos to fix the surround outputs.  However, this overrides the pin
configs of the mic pins as if they are outputs-only, effectively
disabling the mic inputs.  Of course, it's a regression wrt mic
functionality.

Actually the pins 0x18 and 0x1a don't need to be changed; we just need
to disable the bogus pins 0x14 and 0x15.  Then the auto-parser will
pick up mic pins as switchable and assign the surround outputs there.

This patch removes the incorrect pin overrides of NID 0x18 and 0x1a
from the ASRock fixup.

Latest Thinkpad laptops use the HKEY_HID LEN0268 instead of the

After adding the new HKEY_HID into the is_thinkpad(), both of them

Support was added to allow location of both CPU and CODEC components
of a DAI link from their parent's of_node if they did not have an

commit 3e0aa8d83b ("ASoC: core: If component doesn't have of_node
                      use parent's node instead")

However this leaves platforms as something of a special case as the
major DAI component that doesn't do this. Since this is useful for MFD
devices which often utilise a single device tree entry for the whole
device, add support for looking up platforms from the parent's of_node
as well.

2bea8f97d4 ASoC: stac9766: Remove register paging support
The AC'97 standard defines paging support for the register range 0x60-0x6f.
Meaning registers in this window are mapped to different physical registers
depending on the setting of the page select register (0x24).

The stac9766 implements support for switching between page 0 and page 1
depending on the addressed register. But the driver never accesses any
registers from page 1, in addition page 0 is the page selected by default.

Considering the development history it is unlikely that the driver will see
any new features that require paging support. Removing the paging support
makes transitioning the driver to regmap a bit more straight forward.

The default register value table is update to contain the values from page
0, rather than page 1.

730e2dd0cb ASoC: sun4i-codec: Increase DMA max burst to 8
According to the DMA engine API documentation, maxburst denotes the
largest possible size of a single transfer, so as not to overflow
destination FIFOs as explained in this excerpt from dmaengine.h

 * @src_maxburst: the maximum number of words (note: words, as in
 * units of the src_addr_width member, not bytes) that can be sent
 * in one burst to the device. Typically something like half the
 * FIFO depth on I/O peripherals so you don't overflow it. This
 * may or may not be applicable on memory sources.
 * @dst_maxburst: same as src_maxburst but for destination target
 * mutatis mutandis.

The TX FIFO is 64 samples deep for stereo, and the RX FIFO is 16
samples deep. So maxburst could be 32 and 8 for TX and RX respectively.

Unfortunately the sunxi DMA controller driver takes maxburst as
the requested burst size, rather than a limit, and returns an error
for unsupported values. The original value was 4, but some later
SoCs do not officially support this burst size.

This patch increases maxburst on the TX side to 8, which is supported
by all variants of the sunxi DMA controller.

The A31s, A23, and H3 have a similar PCM interface, again with register
offsets slightly rearranged. The analog path controls, while very
similar between them and the A31, have been moved a separate bus which
is accessed through a message box like interface in the PRCM address
range. This would be handled by a separate auxiliary device tied in
through the device tree in its supporting create_card function.

The quirks structure is expanded to include different register offsets
and separate callbacks for creating the ASoC card. The regmap_config,
quirks, and of_device_match tables have been moved to facilitate this.

2f2a3462bc ASoC: sun4i-codec: Move data structures to add create_card call to quirks
The audio codec on later Allwinner SoCs have a different layout and
audio path compared to the A10/A20. However the PCM parts are still
the same.

The different layout and audio paths mean we need a different
create_card function for different families, so they can create
DAPM endpoint widgets and routes.

This patch moves the regmap configs, quirks and of_device_id
structures to just before the probe function, so we can, among other
things, include a pointer for the create_card function. None of the
lines of code were changed.

a83e3b4c44 ASoC: Intel: Skylake: Add D0i3 mode ref counting
For device opened/closed, we check the D0i3 capability for the device
and invoke skl_tplg_d0i3_get/put, which counts the use case based on the
mode supported.

These counters are then used to decide if the device can enter D0i3 mode
of streaming or non-streaming or no D0i3.

6bd9dcf339 ASoC: Intel: Skylake: Add support for specifying D0i3 configuration
Not all use cases can support Doi3. Only certain use cases like hot word
detection, deep buffering can support D0i3 based on resource requirement.

So, pass the D0i3 capability for the FE/BE copier using topology. This will
be used to take a decision for D0i3 mode entry/exit.

8a0cb2360d ASoC: Intel: Skylake: Add support for LPMode
For D0i3, we need to tell DSP to run the pipelines in LP mode. This
information is kept in topology and passed to driver as an attribute
for pipe.

So add a new tuple for lpmode and program the pipe based on value set.

a26a3f53e3 ASoC: Intel: Skylake: Add support for programming D0i3C
To set the controller in D0i3 mode, the driver needs to set D0i3C
register after DSP is quiesced. Since the D0iX entry/exit is done by IPC,
add this as callback so that it can be invoked from IPC module.

41b7523f19 ASoC: Intel: Skylake: Add D0iX IPCs
The audio DSP supports intermediate power states between D0 and D3
states. These states are D0i0 and D0i3 states.

Collectively we refer these two states as D0iX states.

To set or wake up from these states, driver also needs to send an IPC "Set D0iX
IPC" before doing anything else.

Add support for this new IPC messages.

80a0df1819 ASoC: Intel: Add sst_ipc_tx_message_nopm
If the DSP is in low power mode, it needs to be woken up by a "wake" IPC
to set it into the D0 state before we can send any other IPC command.

The call flow is that the driver calls sst_ipc_tx_message_wait() to send any
IPC and this call checks if the device is in low power mode and in that
case we need to send the wake IPC.

So add a new IPC nopm variant which can be called from driver and
doesn't check for power state (as we already know that) and avoids
circular dependency of again checking power state.
