Currently timeout for autoenumeration during probe and bus reset is set to
2 secs which is really a big value. This can have an adverse effect on
boot time if the slave device is not ready/reset.
This was the case with wcd938x which was not reset yet but we spent 2
secs waiting in the soundwire controller probe. Reduce this time to
1/10 of Hz which should be good enough time to finish autoenumeration
if any slaves are available on the bus.

In typical use cases, the peripheral becomes pm_runtime active as a
result of the ALSA/ASoC framework starting up a DAI. The parent/child
hierarchy guarantees that the manager device will be fully resumed
beforehand.
There is however a corner case where the manager device may become
pm_runtime active, but without ALSA/ASoC requesting any functionality
from the peripherals. In this case, the hardware peripheral device
will report as ATTACHED and its initialization routine will be
executed. If this initialization routine initiates any sort of
deferred processing, there is a possibility that the manager could
suspend without the peripheral suspend sequence being invoked: from
the pm_runtime framework perspective, the peripheral is *already*
suspended.
To avoid such disconnects between hardware state and pm_runtime state,
this patch adds an asynchronous pm_request_resume() upon successful
attach/initialization which will result in the proper resume/suspend
sequence to be followed on the peripheral side.

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 e38f9ff63e ("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.

This patch adds a status check after device0 attachment to solve race
conditions observed during attachment with multiple devices per link
The sequence is the following
1) deviceA attaches as device0
2) the hardware detects a device0 status change and throws an
interrupt.
3) the interrupt handler schedules the work function
4) the workqueue starts, we read the status
slave0 = cdns_readl(cdns, CDNS_MCP_SLAVE_INTSTAT0);
slave1 = cdns_readl(cdns, CDNS_MCP_SLAVE_INTSTAT1);
we deal with the status change and program deviceA device number to a
non-zero value.
5) deviceB attaches as device0, the device0 status seen by the
hardware does not change.
6) we clear the CDNS_MCP_SLAVE_INTSTAT0/1 registers -> we will never detect
deviceB!
This patch suggest re-checking in a loop the device0 status with a
PING frame, i.e. using the real device0 status instead of information
on status changes.

The stream management currently flags an 'inconsistent state' error
when a change is requested multiple times. This was added on purpose
to identify programming mistakes.
In hindsight, there was no real reason to fail if the logic at the
ASoC-DPCM level invokes the same callback multiple times. It's
perfectly acceptable to just return and not flag an error when there
is nothing to do. The main concern with the state management is to
trap errors such as trying to enable a stream that was not prepared
first.
This patch suggests allowing the stream functions to be idempotent,
i.e. they can be called multiple times.
Note that the prepare case was already handling multiple calls, this
was added in commit c32464c939 ("soundwire: stream: only prepare
stream when it is configured.")

This change removes a kfree() on a configuration error, this should
have not impact on existing platforms and error handling will be

In rare cases, some devices seem to lose sync and never re-attach on
the bus. This seems to happen only when there are more than one device
per link, which suggests either an electrical issue, a race condition
or a state machine issue.
Add two dev_warn() messages to identify the sequence by which the
devices become UNATTACHED.

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.

The HDAudio ASoC support relies on the set_tdm_slots() helper to store
the HDaudio stream tag in the tx_mask. This only works because of the
pre-existing order in soc-pcm.c, where the hw_params() is handled for
codec_dais *before* cpu_dais. When the order is reversed, the
stream_tag is used as a mask in the codec fixup functions:
/* fixup params based on TDM slot masks */
if (substream->stream == SNDRV_PCM_STREAM_PLAYBACK &&
codec_dai->tx_mask)
soc_pcm_codec_params_fixup(&codec_params,
codec_dai->tx_mask);
As a result of this confusion, the codec_params_fixup() ends-up
generating bad channel masks, depending on what stream_tag was
allocated.
We could add a flag to state that the tx_mask is really not a mask,
but it would be quite ugly to persist in overloading concepts.
Instead, this patch suggests a more generic get/set 'stream' API based
on the existing model for SoundWire. We can expand the concept to
store 'stream' opaque information that is specific to different DAI
types. In the case of HDAudio DAIs, we only need to store a stream tag
as an unsigned char pointer. The TDM rx_ and tx_masks should really
only be used to store masks.
Rename get_sdw_stream/set_sdw_stream callbacks and helpers as
get_stream/set_stream. No functionality change beyond the rename.

This patch provides both a simplification of the suspend flows and a
better balanced operation during suspend/resume transition, as part of
the transition of Sound Open Firmware (SOF) to dynamic pipelines: the
DSP resources are only enabled when required instead of enabled on
startup.
The exiting code relies on a convoluted way of dealing with suspend
signals. Since there is no .suspend DAI callback, we used the
component .suspend and marked all the component DAI dmas as
'suspended'. The information was used in the .prepare stage to
differentiate resume operations from xrun handling, and only
reinitialize SHIM registers and DMA in the former case.
While this solution has been working reliably for about 2 years, there
is a much better solution consisting in trapping the TRIGGER_SUSPEND
in the .trigger DAI ops. The DMA is still marked in the same way for
the .prepare op to run, but in addition the callbacks sent to DSP
firmware are now balanced.
Normal operation:
hw_params -> intel_params_stream
hw_free -> intel_free_stream
suspend -> intel_free_stream
prepare -> intel_params_stream
This balanced operation was not required with existing SOF firmware
relying on static pipelines instantiated at every boot. With the
on-going transition to dynamic pipelines, it's however a requirement
to keep the use count for the DAI widget balanced across all
transitions.
The component suspend is not removed but instead modified to deal with
a corner case: when a substream is PAUSED, the ALSA core does not
throw the TRIGGER_SUSPEND. This is problematic since the refcount for
all pipelines and widgets is not balanced, leading to issues on
resume. The trigger callback keeps track of the 'paused' state with a
new flag, which is tested during the component suspend called later to
release the remaining DSP resources. These resources will be
re-enabled in the .prepare step.
The IPC used in the TRIGGER_SUSPEND to release DSP resources is not a
problem since the BE dailink is already marked as non-atomic.
