Chao Song 3d912d1a28 soundwire: intel: read AC timing control register before updating it
Start from ACE1.x, DOAISE is added to AC timing control
register bit 5, it combines with DOAIS to get effective
timing, and has the default value 1.

The current code fills DOAIS, DACTQE and DODS bits to a
variable initialized to zero, and updates the variable
to AC timing control register. With this operation, We
change DOAISE to 0, and force a much more aggressive
timing. The timing is even unable to form a working
waveform on SDA pin on Meteorlake.

This patch uses read-modify-write operation for the AC
timing control register access, thus makes sure those
bits not supposed and intended to change are not touched.

Pierre-Louis Bossart 1d905d355e ASoC: SOF/soundwire: re-add substream in params_stream structure
An earlier simplification to only pass the direction is no longer
suitable, all the ACE2.x HDaudio DMA management relies on access to
the substream structure.

This patch is an iso-functionality change, the HDaudio DMA parts will
be provided separately.

Pierre-Louis Bossart 0a0d1740bd soundwire: intel: don't save hw_params for use in prepare
The existing code copies the hw_params pointer and reuses it later in
.prepare, specifically to re-initialize the ALH DMA channel
information that's lost in suspend-resume cycles.

This is not needed, we can directly access the information from the
substream/rtd - as done for the HDAudio DAIs in
sound/soc/sof/intel/hda-dai.c

In addition, using the saved pointer causes the suspend-resume test
cases to fail on specific platforms, depending on which version of GCC
is used. Péter Ujfalusi and I have spent long hours to root-cause this
problem that was reported by the Intel CI first with 6.2-rc1 and again
v6.3-rc1. In the latter case we were lucky that the problem was 100%
reproducible on local test devices, and found out that adding a
dev_dbg() or adding a call to usleep_range() just before accessing the
saved pointer "fixed" the issue. With errors appearing just by
changing the compiler version or minor changes in the code generated,
clearly we have a memory management Heisenbug.

The root-cause seems to be that the hw_params pointer is not
persistent. The soc-pcm code allocates the hw_params structure on the
stack, and passes it to the BE dailink hw_params and DAIs
hw_params. Saving such a pointer and reusing it later during the
.prepare stage cannot possibly work reliably, it's broken-by-design
since v5.10. It's astonishing that the problem was not seen earlier.

This simple fix will have to be back-ported to -stable, due to changes
to avoid the use of the get/set_dmadata routines this patch will only
apply on kernels older than v6.1.

Now that the bus start/stop/clock_stop sequences use the ops, we can
move them to a different file to reuse them.

Note that we could in theory remove the abstraction for all those
sequences and directly call the functions in intel_auxdevice.c. To
allow for more flexibility and have means to special-case new
platforms, we decided to keep the abstraction. If in time it becomes
clear there is no benefit the abstraction will be simplified.

In the existing code, the SHIM_SYNC::SYNC_GO bit is set, and the code
waits for it to return to zero.

That second wait part is just wrong: the SYNC_GO bit is *write-only* so
there's no way to know if it's cleared by hardware. The code works
because the value for a read-only bit is zero, but that's really just
luck.

Simplify the sequence to a plain read-modify-write.

Pierre-Louis Bossart 5c2f4c9cfc soundwire: intel: remove DAI startup/shutdown
The only thing these DAI startup/shutdown callbacks do is play with
pm_runtime reference counts.

This is not wrong, but it's not necessary at all. At the ASoC core level,
only the component matters for pm_runtime. The ASoC core already calls
pm_runtime_get_sync() in snd_soc_pcm_component_pm_runtime_get(),
before the DAI startup callback is invoked.

None of the SoundWire codec drivers rely on pm_runtime helpers in
their DAI startup/shutdown either. This adds to the evidence that only
the component, or more precisely the device specified when registering
a component, should deal with pm_runtime transitions.

Beyond the code cleanup, this move prepares for the addition of link
power management in the auxiliary device startup/resume/suspend
callbacks. The DAI callbacks can by-design assume that the device is
already pm_runtime active.

Sjoerd Simons 13c30a7558 soundwire: intel: Initialize clock stop timeout
The bus->clk_stop_timeout member is only initialized to a non-zero value
during the codec driver probe. This can lead to corner cases where this
value remains pegged at zero when the bus suspends, which results in an
endless loop in sdw_bus_wait_for_clk_prep_deprep().

Corner cases include configurations with no codecs described in the
firmware, or delays in probing codec drivers.

Initializing the default timeout to the smallest non-zero value avoid this
problem and allows for the existing logic to be preserved: the
bus->clk_stop_timeout is set as the maximum required by all codecs
connected on the bus.

Linus Torvalds 668c3c237f sound updates for 6.0-rc1
As 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)

Pierre-Louis Bossart 3e9c9f9057 soundwire: intel: use pm_runtime_resume() on component probe
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.

Pierre-Louis Bossart e286472cff soundwire: intel: disable WAKEEN in pm_runtime resume
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().
