The probes (the ability of probing the audio data from firmware processing
points or to receive stream of debug/trace information) is supported by IPC4
as well, but due to the differences between the two IPC version the low level
setup and information we need for probing is different.
This series will extend the existing probes support for IPC3 with IPC4 'backend'
snd_soc_util_exit() is called in __init snd_soc_init() for cleanup.
Remove the __exit annotation for it to fix the build warning:

This patchset adds support to multi-port connections between AudioReach Modules
which is required for sophisticated graphs like ECNS or Speaker Protection.
Also as part of ECNS testing new module support for SAL and MFC are added.
Tested on SM8450 with ECNS.

Existing HDaudio controllers expose an HDAudio DMA which is used to
interface with HDaudio codecs. All other interfaces supported by Intel
(SoundWire, SSP, DMIC) rely for data transfers on another GP-DMA
managed by the DSP firmware - the HDaudio DMA is only used for
memory-to-DSP transfers.
New HDaudio extensions will enable the use of this HDaudio DMA for all
of SoundWire, SSP, DMIC. These extensions will be backwards-compatible
for HDaudio and iDISP codecs, but will require new programming
sequences and DAI callbacks for SoundWire, SSP and DMIC.
Before we add support for 'extended audio links' and the programming
sequences for the DMA, we need to refactor the code. All HDaudio codec
support needs to be well identified in a separate file, and likewise
all the 'multi-link' handling needs to be better split.
This patchset removes a number of 'old' Kconfig dependencies and
options, adds helpers with a fallback to remove IS_ENABLED checks in
the code and tries to simplify programming sequences when possible.
One indirect benefit from this refactoring is that developers can
switch with a kernel parameter from HDaudio support to a variant of
'nocodec' support. This proves extremely useful to test on existing
Intel RVPs and Up boards, where the same build can be used to check 3
interfaces (HDaudio, SSP, DMIC) by just removing modules, setting the
kernel parameter and reloading modules.

Goal of the series is implementation of suspend/resume operations for a
PCM stream along with all the collaterals connected to the subject.
Start with splitting avs_dai_fe_hw_free() as ideally we would like to
reuse as much of existing code as possible but snd_pcm_lib_free_pages()
is not desired part of the function when speaking of suspend operation.
The actual implementation of suspend/resume() for component drivers
follows. For most scenarios, the PM flow is similar to standard
streaming one, except for the part where the position register are being
saved and the lack of PCM pages freeing. To reduce code duplication, all
avs_dai_suspend_XXX() and avs_dai_resume_XXX() functions reuse their
non-PM equivalents.
Order of operations is affected by the fact that path binding/unbinding
happens only in FE part of the stream.
Above essentially unlocks SX+streaming scenarios i.e.: power transitions
with an ongoing stream.
As some streams are allowed to run in low power state, support is
provided for S0iX state. The handlers check ACPI capabilities and the
number of active low-power paths before deciding between SX and S0iX
flows.
The last portion of the patchset is addition of power/clock gating
overrides. There is no single set of registers that ensures AudioDSP
firmware loads 100% of time on every single configuration. By having
them exposed, user can have the loading procedure behavior adjusted for
their configuration without having to recompile the kernel.
AudioReach Modules can connect to other modules using source and
destination port, and each module in theory can support up to 255 port
connections. But in practice this limit is at max 8 ports at a time.
So add support for allowing multiple port connections.
This support is needed for more detailed graphs like ECNS, speaker
protection and so.

Current AudioReach design of connecting FE and BE graph is very complicated
and not reliable. Instead used the virtual damp widgets private data to help
identify the modules that needs connection at runtime. Also maintain a
inter-graph connection info in the graph info, which can be used to both
determine if the graphs are connected and at graph build time.

The existing NOCODEC mode enforces a build-time mutual exclusion with
the HDaudio link support, mostly to avoid any dependency on the
snd_hdac library and references to HDAudio codec/i915 stuff.
This is very useful to track dependencies and test a minimal
configuration, but very painful for developers and CI: a recompilation
and reinstall of the kernel modules is required.
This patch suggests an alternate middle ground where the selection of
the machine driver and all codec-related actions are bypassed at
run-time, contingent on a kernel module parameter being set.
For example setting BIT(10) with
'options snd_sof sof_debug=0x401'
is enough to switch from an HDaudio card to a nocodec one.
This new DEBUG_NOCODEC mode is not suitable for distributions and
end-users. It's not even recommended on all platforms, i.e. the
NOCODEC mode is known not to work on specific devices where the BIOS
did not configure support for I2S/DMIC interfaces. The usual
development devices such as Chromebooks, Up boards and Intel RVP are
the only recommended platforms where this mode can be supported.
Note that the dynamic switch between HDaudio and nocodec may not
always possible depending on hardware layout, pin-mux options, and
BIOS settings. The audio subsustems on Intel platforms has to support
4 types of interfaces and pin-mux can be complicated.
Reviewers might ask: why didn't we do this earlier? The main reason is
that all the codec-related configurations were not cleanly separated
out in the sof/intel directory. With all the cleanups done recently,
adding this opt-in behavior is relatively straightforward.
Tested on UpExtreme (WHL) and UpExtreme i11 (TGL).

Provide pgctl/cgctl_mask module parameters for overriding power and
clock gating policies respectively. These help deal with rare firmware
loading failures on some configurations. There're no golden masks that
cover all known problems so leave the defaults as is.
While at it, update avs_hda_l1sen_enable()'s definition so it aligns
with its power/clock friends.

Introduce avs_suspend_standby() and avs_resume_standby() to support S0IX
streaming. The AudioDSP is not shutdown during such scenario and the PCI
device is armed for possible wake operation through an audio event.
As capability for a stream to be active during low power S0 is based off
of ->ignore_suspend, adjust the field's value according to platform
capabilities if needed.

Implement suspend/resume() operations for component drivers. For most
scenarios, the PM flow is similar to standard streaming one, except for
the part where the position register are being saved and the lack of PCM
pages freeing. To reduce code duplication, all avs_dai_suspend_XXX() and
avs_dai_resume_XXX() functions reuse their non-PM equivalents.
Given that path binding/unbinding happens only in FE part of the stream,
the order of suspend() goes:
1. hw_free() all FE DAIs, paths are unbound here
2. hw_free() all BE DAIs
Consequently, for resume() its:
1. hw_params() all BE DAIs
2. hw_params() all FE DAIs, paths are bound here
3. prepare() all BE DAIs
4. prepare() all FE DAIs
As component->suspend/resume() do not provide substream pointer, store
it ourselves so that the PM flow has all the necessary information to
proceed.
