Add a new client driver for probes support and move
all the probes-related code from the core to the
client driver.
The probes client driver registers a component driver
with one CPU DAI driver for extraction and creates a
new sound card with one DUMMY DAI link with a dummy codec
that will be used for extracting audio data from specific
points in the audio pipeline.
The probes debugfs ops are based on the initial
implementation by Cezary Rojewski and have been moved
out of the SOF core into the client driver making it
easier to maintain. This change will make it easier
for the probes functionality to be added for all platforms
without having the need to modify the existing(15+) machine
drivers.

A client in the SOF (Sound Open Firmware) context is a driver that needs
to communicate with the DSP via IPC messages. The SOF core is responsible
for serializing the IPC messages to the DSP from the different clients.
One example of an SOF client would be an IPC test client that floods the
DSP with test IPC messages to validate if the serialization works as
expected.
Multi-client support will also add the ability to split the existing audio
cards into multiple ones, so as to e.g. to deal with HDMI with a dedicated
client instead of adding HDMI to all cards.
This patch introduces descriptors for SOF client driver and SOF client
device along with APIs for registering and unregistering a SOF client
driver, sending IPCs from a client device and accessing the SOF core
debugfs root entry.
Along with this, add a couple of new members to struct snd_sof_dev that
will be used for maintaining the list of clients.

Hi,
The probe debug feature of SOF can be used to extract streams of data from a
given point of a pipeline for analysis.
The support is implemented by using the ALSA/ASoC compress support for the
capture stream, but the code can not be used by/for a normal compressed data
stream. It is a debug feature.
Merge the probe implementation in the core (compress.c/h and probe.c/h) into
one file: sof-probes.c/h
Rename the Intel HDA specific probe implementation from hda-compressc.c to
hda-probes.c
We also need to add IPC logging support for the probes messages and drop the
unused references to SOF compress to have reasonably clean code.
Regards,
Peter

Invoke release_firmware() when the firmware fails to boot in
sof_probe_continue().
The request_firmware() framework must be informed of failures in
sof_probe_continue() otherwise its internal "batching"
feature (different from caching) cached the firmware image
forever. Attempts to correct the file in /lib/firmware/ were then
silently and confusingly ignored until the next reboot. Unloading the
drivers did not help because from their disconnected perspective the
firmware had failed so there was nothing to release.
Also leverage the new snd_sof_fw_unload() function to simplify the
snd_sof_device_remove() function.

Most distributions do not enable the SOF developer options and
specifically the DMA trace. This is problematic for end-user/community
support since the sof-logger tool cannot extract valuable information.
Conversely in rare cases the DMA trace can lead to Heisenbugs by
creating more traffic to system memory and more interrupts.
This patch changes the logic so that the Kconfig value is used as a
default value for a module parameter, but this value can be changed as
needed. Users can override the distro DMA trace selection.

With current delayed probe implementation, sof_probe_complete is not
called in case of errors. And as this function is responsible for
decrementing runtime pm usage counter, this will result in following
problem:
- probe driver in conditions where probe will fail (to force
the condition on Intel SOF systems, set
"snd_sof_intel_hda_common.codec_mask=0")
- unload driver (runtime-pm usage_count is leaked)
- fix the issue by installing missing fw, modifying module parameters,
etc actions
- try to load driver again -> success, probe ok
-> device never enters runtime suspend
Fix the issue by storing result of delayed probe to a state variable and
providing new snd_sof_device_probe_completed() to be queried from SOF
PCI/ACPI/OF drivers.
If probe never completed successfully, runtime PM was not set up and
thus at remove(), we should not increment usage count anymore.

This patch invokes the DSP power down notifier to inform
DSP that driver is going to be removed.
The module removal entails DSP power down, disabling of
IRQs and more. Therefore it is highly recommended to inform
the DSP about this upcoming event.
Due to hardware limitations on some Intel platforms it is necessary
to power gate all LPSRAM banks that were enabled prior to controller
reset. Otherwise, an attempt to write LPSRAM control registers may
have no effect.

Define system-agnostic probe compress flow which serves as a base for
actual, hardware-dependent implementations.
As per firmware spec, maximum of one extraction stream is allowed, while
for injection, there can be plenty.
Apart from probe_pointer, all probe compress operations are mandatory.
Copy operation is defined as unified as its flow should be shared across
all SOF systems.

The DSP device substates such as D0I0/D0I3
are platform-specific. Therefore, the d0_substate
field of struct snd_sof_dev is replaced
with the dsp_power_state field which represents the current
state of the DSP. This field holds both the device state
and the platform-specific substate values.
With the DSP device substates being platform-specific,
the DSP power state transitions need to be performed in
the platform-specific suspend/resume ops as well.
In order to achieve this, the ops signature has to be
modified to pass the target device state as an
argument. The target substate will be determined by
the platform-specific ops before performing the transition.
For example, in the case of the system suspending to S0IX,
the top-level SOF device suspend callback needs to
only determine if the DSP will be entering
D3 or remain in D0. The target substate in case the device
needs to remain in D0 (D0I0 or D0I3) will be determined
by the platform-specific suspend op.
With the addition of the extended set of power states for the DSP,
the set_power_state op for HDA platforms has to be extended
to handle only the appropriate state transitions. So, the
implementation for the Intel HDA platforms is also modified.
