Nikita Yushchenko ef9656b693 ASoC: tlv320aic31xx: add explicit support for tlv320dac31xx
tlv320dac31xx is a subset of tlv320aic31xx:
- it does not have MIC inputs and ADC, thus capture is not supported,
- it has analog inputs AIN1/AIN2 that can be mixed into output.

Although tlv320dac31xx does work with tlv320aic31xx driver, this setup
does register non-existent widgets and non-existent capture stream.
Thus userspace lists non-existent objects in user interfaces, an can
access these, causing operations with device registers that are
declared as "reserved" in tlv320dac31xx datasheet.

This patch fixes this situation by separating controls/widgets/routes
into common, aic31xx-specific, and dac31xx-specific parts. Only parts
that match actual hardware (as declared in "compatible" device tree
property) are registered.

Changes from v1:
- update device tree binding documentation,
- rebased on top of "ASoC: codec duplicated callback function goes to
  component on tlv320aic31xx" commit.

Currently if AAD is enabled in the device, during system suspend
the feature remains, regardless of whether the codec is a wake-up

Charles Keepax 57a60cc361 ASoC: wm_adsp: Allow preloader to do the final shutdown of the DSP
The booting process for the DSP is clearly separated into two parts, the
preloader brings up the core and downloads code, then the main widget
starts the code actually executing. However the shutdown sequence is all
handled with the main widget.

To allow the preloading to be run independently of the main audio bring
up it makes sense, and is generally just cleaner, for the preloader
widget to shutdown those things it initialised. This patch moves the
appropriate parts of the shutdown process into the preloader widget.

Charles Keepax 5ca7e170e3 ASoC: wm_adsp: Make DSP preloader a supply widget
Currently the DSP loading is split into two widgets, the preloader that
is a snd_soc_dapm_dai_link widget which starts a thread to download
the firmware, and the DSP itself which is a snd_soc_dapm_out_drv and
synchronises the thread back in to the DAPM sequence. This allows the
firmware download to be overlapped with the rest of the path bring up.

The use of a snd_soc_dapm_dai_link widget requires the preloader to be part
of the audio path in DAPM, really a supply widget is a better fit for the
preloader. The preloader is something that needs to be done for the DSP to
function, not a part of the audio path itself.

This change makes the DSP preloader widget a supply widget, which as well
as probably being a better fit will also make it much simpler to power up
the preloader widget to trigger firmware download to the core independently
of the audio path coming up.

Charles Keepax 3577357a16 ASoC: arizona: Attach SYSCLK to DSP preloaders
Currently SYSCLK is attached to every compressed DAI as this follows the
pattern of attaching clocks to the chips inputs and outputs, however, it is
really the DSP that requires the clock here. As firmware download can be a
significant part of the path startup time for these devices occasionally it
would be desirable to download the firmware in advance of the path being
brought up.

To help facilitate this early firmware loading this patch attaches the
SYSCLK to the DSP preloader widget. This also saves us adding a new route
to SYSCLK every time a new compressed DAI is created.

As part of the work to download firmware before the audio path is brought
up the DSP will be put into a low power state between downloading firmware
to the core and starting it running. This will mean that the firmware ALSA

To prepare for this change we gate access to the hardware in the ALSA
control handlers on the DSP being running rather than simply booted and
move the synchronisation of the control caches out of the preloader delayed
work and into the main DAPM thread after the DSP will have been brought out
of its low power state.

so really it currently indicates that the core has been booted and is

But, we have upper bound of instance ID. The current IDs are coming from

id's subject to upper bounds as we can create a big graph but not all
parts running at same time.

Anssi Hannula eb1a74b7be ALSA: usb-audio: Extend DragonFly dB scale quirk to cover other variants
The DragonFly quirk added in 42e3121d90 ("ALSA: usb-audio: Add a more
accurate volume quirk for AudioQuest DragonFly") applies a custom dB map
on the volume control when its range is reported as 0..50 (0 .. 0.2dB).

However, there exists at least one other variant (hw v1.0c, as opposed
to the tested v1.2) which reports a different non-sensical volume range
(0..53) and the custom map is therefore not applied for that device.

This results in all of the volume change appearing close to 100% on
mixer UIs that utilize the dB TLV information.

Add a fallback case where no dB TLV is reported at all if the control
range is not 0..50 but still 0..N where N <= 1000 (3.9 dB). Also
restrict the quirk to only apply to the volume control as there is also
a mute control which would match the check otherwise.

Michael Ellerman ef24ba7091 powerpc: Remove all usages of NO_IRQ
NO_IRQ has been == 0 on powerpc for just over ten years (since commit
0ebfff1491 ("[POWERPC] Add new interrupt mapping core and change
platforms to use it")). It's also 0 on most other arches.

Although it's fairly harmless, every now and then it causes confusion
when a driver is built on powerpc and another arch which doesn't define
NO_IRQ. There's at least 6 definitions of NO_IRQ in drivers/, at least
some of which are to work around that problem.

So we'd like to remove it. This is fairly trivial in the arch code, we
just convert:

    if (irq == NO_IRQ)	to	if (!irq)
    if (irq != NO_IRQ)	to	if (irq)
    irq = NO_IRQ;	to	irq = 0;
    return NO_IRQ;	to	return 0;

And a few other odd cases as well.

At least for now we keep the #define NO_IRQ, because there is driver
code that uses NO_IRQ and the fixes to remove those will go via other
trees.

Note we also change some occurrences in PPC sound drivers, drivers/ps3,
and drivers/macintosh.

Bhaktipriya Shridhar 8891098246 ASoC: tlv320dac33: Remove deprecated create_singlethread_workqueue
The workqueue "dac33_wq" queues a single work item &dac33->work and
hence doesn't require ordering. Also, it is not being used on a memory
reclaim path. Hence, it has been converted to use system_wq.

System workqueues have been able to handle high level of concurrency
for a long time now and hence it's not required to have a singlethreaded
workqueue just to gain concurrency. Unlike a dedicated per-cpu workqueue
created with create_singlethread_workqueue(), system_wq allows multiple
work items to overlap executions even on the same CPU; however, a
per-cpu workqueue doesn't have any CPU locality or global ordering
guarantee unless the target CPU is explicitly specified and thus the
increase of local concurrency shouldn't make any difference.

The work item has been flushed in dac33_soc_remove to ensure that
there are no pending tasks while disconnecting the driver.

Adam Thomson 6a0b87c6e7 ASoC: da7219: Support HP detect procedure when MCLK not present
Currently the driver code assumes that MCLK will be present during
the procedure, or if it has control of MCLK then it can make sure
it's enabled. Some platforms however do not provide MCLK to the
driver in this way, and will not leave MCLK enabled when Codec is
in STANDBY state.

This patch adds support for the HP detect procedure when running
from the device's internal oscillator, to ensure all platforms
can make use of this feature correctly.

Takashi Iwai 09da111aef ALSA: hda - Skip Realtek SKU check for Lenovo machines
Realtek codec driver expects an implicit rule where either the codec
SSID or the pincfg NID 0x1d contains the some information encoded in
some bits.  One of the expected information is there is the
availability of PC beep, and the driver doesn't build up the PC beep
control if this is *supposed* to be disabled there.

Meanwhile, Lenovo doesn't seem to follow this requirement (yes it's
non-standard after all), and the BIOS sets just the normal SSID and
the pincfg values.  This resulted in the lack of PC beep on a few
machines, purely with a lucky or unlucky number.  It didn't bother
most people, but some people still demand the PC beep, as found in bug
reports.

This patch just adds the fixup chain to Lenovo machines to skip the
SKU checks.  Then the beep control will show up in the mixer, and user
can still decide to enable / disable it via the standard mixer
interface.

Takashi Iwai 816f318b23 ALSA: rawmidi: Fix possible deadlock with virmidi registration
When a seq-virmidi driver is initialized, it registers a rawmidi
instance with its callback to create an associated seq kernel client.
Currently it's done throughly in rawmidi's register_mutex context.
Recently it was found that this may lead to a deadlock another rawmidi
device that is being attached with the sequencer is accessed, as both
open with the same register_mutex.  This was actually triggered by
syzkaller, as Dmitry Vyukov reported:

   lock(register_mutex#5);

 *** DEADLOCK ***
======================================================

The fix is to simply move the registration parts in
snd_rawmidi_dev_register() to the outside of the register_mutex lock.
The lock is needed only to manage the linked list, and it's not
necessarily to cover the whole initialization process.
