Pull sound updates from Takashi Iwai:
 "As the diffstat shows, we've had lots of developments in a wide range
  at this time; the majority of changes are about ASoC, including
  subsystem-wide cleanups, continued SOF / Intel updates and a bunch of
  new drivers (as usual), while there have been some significant (but
  almost invisible) improvements in ALSA core side, too.

  Below are some highlights:

  Core:

   - Faster lookups of control elements with Xarray; normal user won't
     notice, but on the devices with tons of control elements, it can be
     visibly faster

   - Support for input validation for controls; this will harden for
     badly written drivers in general with a slight overhead

   - Deferred async signal handling for working around the potential
     deadlocks

   - Cleanup / refactoring raw MIDI locking code

  ASoC:

   - Restructing of the set_fmt() callbacks for making things clearer in
     situations like CODEC to CODEC links

   - Clean up and modernizing the DAI naming scheme setups

   - Merge of more of the Intel AVS driver stack, including some board
     integrations

   - New version 4 mechanism for communication with SOF DSPs

   - Suppoort for dynamically selecting the PLL to use at runtime on
     i.MX platforms

   - Improvements for CODEC to CODEC support in the generic cards

   - Support for AMD Jadeite and various machines, AMD RPL, Intel
     MetorLake DSPs, Mediatek MT8186 DSPs and MT6366, nVidia Tegra
     MDDRC, OPE and PEQ, NXP TFA9890, Qualcomm SDM845, WCD9335 and
     WAS883x, and Texas Instruments TAS2780

  HD- and USB-audio:

   - Continued improvement for CS35L41 (sub)codec support

   - More quirks for various devices (HP, Lenovo, Dell, Clevo)"

When a pipeline is split into FE and BE parts, the BE pipeline may need to
be triggered separately in the BE trigger op. So add the trigger callback
in the link_res ops that will be invoked during BE DAI trigger.

<title>soundwire: intel: use pm_runtime_resume() on component probe</title>

During the card registration, transactions on the SoundWire bus can be
initiated. If the ALSA card is registered after the bus suspends,
timeouts can be seen while reading/writing codec registers. This is
extremely easy to reproduce in driver bind/unbind tests.

In an initial experiment, the ASoC soc-component.c code was modified
to initiate a pm_runtime resume on a component probe. The results
showed this was too invasive. Instead this patch suggests resuming the
SoundWire component only.

Because of the parent-child hierarchy enforced by the pm_runtime
framework, it can be argued that the codec component probe should be
enough to resume all necessary devices, and indeed the same resume
will be applied to SoundWire codecs used on Intel platforms.

Calling pm_runtime_resume() on both the Intel and codec sides has the
benefit of resuming the bus without assuming any order during the card
registration. The first component on a dailink to be probed will
resume the bus. In addition, if a codec driver did not implement this
transition, the Intel component would still resume the bus and avoid
timeouts on card registration.

Change the legacy DAI naming flag from opting in to the new scheme
(non_legacy_dai_naming), to opting out of it (legacy_dai_naming).
This driver appears to be on the CPU side of the DAI link and
currently uses the legacy naming, so add the new flag.

<id>e286472cff8a6785f6fa7950a1ab1b485cc87885</id>
<content type='text'>
When the manager device is pm_runtime resumed, we see a series of
spurious wakes and attempts to resume the same device:

soundwire_intel.link.0: intel_resume_runtime: start
soundwire_intel.link.0: intel_link_power_up: powering up all links
soundwire_intel.link.0: intel_link_power_up: first link up, programming SYNCPRD
soundwire_intel.link.0: intel_shim_wake: WAKEEN disabled for link 0
soundwire_intel.link.0: intel_link_process_wakeen_event: pm_request_resume start
soundwire_intel.link.0: intel_link_process_wakeen_event: pm_request_resume done
soundwire_intel.link.0: intel_shim_wake: WAKEEN disabled for link 0
soundwire_intel.link.0: intel_link_process_wakeen_event: pm_request_resume start
soundwire_intel.link.0: intel_link_process_wakeen_event: pm_request_resume done

This sequence does not break anything but is totally unnecessary.

Currently the wakes are only disabled after the peripheral generates a
wake, e.g. for jack detection.

If the resume is initiated by the host drivers as a result of
userspace actions (play/record typically), we need to disable wake
detection as well. Doing so prevents the spurious wakes and calls to
pm_request_resume().

commit e38f9ff63e6d ("ACPI: scan: Do not add device IDs from _CID if _HID is not valid")
exposes a race condition on a TGL RVP device leading to a timeout.

The detailed analysis shows the RT711 codec driver scheduling a jack
detection workqueue while attaching during a spurious pm_runtime
resume, and the work function happens to be scheduled after the
manager device is suspended.

The direct link between this ACPI patch and a spurious pm_runtime
resume is not obvious; the most likely explanation is that a change in
the ACPI device linked list management modifies the order in which the
pm_runtime device status is checked and exposes a race condition that
was probably present for a very long time, but was not identified.

We already have a check in the .prepare stage, where we will resume to
full power from specific clock-stop modes. In all other cases, we
don't need to resume to full power by default. Adding the
SMART_SUSPEND flag prevents the spurious resume from happening.

manager device is suspended.

The direct link between this ACPI patch and a spurious pm_runtime
resume is not obvious; the most likely explanation is that a change in
the ACPI device linked list management modifies the order in which the
pm_runtime device status is checked and exposes a race condition that
was probably present for a very long time, but was not identified.

We already have a check in the .prepare stage, where we will resume to
full power from specific clock-stop modes. In all other cases, we
don't need to resume to full power by default. Adding the
SMART_SUSPEND flag prevents the spurious resume from happening.

Pull sound updates from Takashi Iwai:
 "It's a relatively calm development cycle, but still lots of updates in
  the driver side like Intel SOF. Below are some highlights:

  ALSA / ASoC core:
   - A new kselftest for ALSA control API
   - PCM NO_REWINDS support
   - Potential race fixes around control removals
   - Unify x86 SG-buffer memory allocation code
   - Cleanups and race fixes for ASoC DPCM locking

  ASoC:
   - Refinements and cleanups around the delay() APIs
   - Wider use of dev_err_probe().
   - Continuing cleanups and improvements to the SOF code
   - Support for pin switches in simple-card derived cards
   - Support for AMD Renoir ACP, Asahi Kasei Microdevices AKM4375, Intel
     systems using NAU8825 and MAX98390, Mediatek MT8915, nVidia Tegra20
     S/PDIF, Qualcomm systems using ALC5682I-VS and Texas Instruments
     TLV320ADC3xxx

  HD-audio / USB-audio:
   - Fix deadlock at HD-audio codec unbinding
   - Fixes for Tegra194 HD-audio, new HDA support for CS35L41 codec
   - Quirks for Lenovo and HP machines, Gigabyte mobo, Bose device

  Misc:
   - Fix virmidi drain behavior

  Note that the merge of CS35L41 codec support is still half-baked, and
  at least one ACPI change is missing. Although this won't hinder the
  kernel build itself, we're going to catch up before RC1"

* tag 'sound-5.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (415 commits)
  ALSA: hda: intel-dsp-config: reorder the config table
  ALSA: hda: intel-dsp-config: add JasperLake support
  ALSA: hda: cs35l41: fix double free on error in probe()
  ALSA: hda: Fix dependencies of CS35L41 on SPI/I2C buses
  ALSA: hda: Fix dependency on ASoC cs35l41 codec
  ASoC: cs35l41: Add support for hibernate memory retention mode
  ASoC: cs35l41: Update handling of test key registers
  ALSA: intel_hdmi: Check for error num after setting mask
  ASoC: wcd9335: Keep a RX port value for each SLIM RX mux
  ASoC: amd: acp: acp-mach: Change default RT1019 amp dev id
  ALSA: virmidi: Remove duplicated code
  ALSA: seq: virmidi: Add a drain operation
  ASoC: topology: Fix typo
  ASoC: fsl_asrc: refine the check of available clock divider
  ASoC: Intel: bytcr_rt5640: Add support for external GPIO jack-detect
  ASoC: Intel: bytcr_rt5640: Support retrieving the codec IRQ from the AMCR0F28 ACPI dev

While the hardware supports PDM streams, this capability has never
been tested or enabled on any product, so this is dead-code. Let's
remove all this.
