293ad28116 ASoC: SOF: Intel: clarify Copyright information
For some reason a number of files included the "All rights reserved"
statement. Good old copy-paste made sure this mistake proliferated.

Remove the "All rights reserved" in all Intel-copyright to align with
internal guidance.

228132b4d8 ASoC: Constify local snd_sof_dsp_ops
Merge series from Krzysztof Kozlowski <krzk@kernel.org>:

The core code does not modify the 'struct snd_sof_dsp_ops' passed via
pointer in various places, so this can be made pointer to const in few
places.  This in turn allows few drivers to have the local (usually
static) 'struct snd_sof_dsp_ops' as const which increased code safety,
as it is now part of rodata.

Not all drivers can be made safer that way. Intel and AMD rely on
customizing that 'struct snd_sof_dsp_ops' before passing to SOF, so they
won't benefit.  They don't lose anything., either.

b32487ca7b ASoC: SOF: debug: Handle cases when fw_lib_prefix is not set, NULL
The firmware libraries are not supported by IPC3, the fw_lib_path is not
a valid parameter and it is always NULL.
Do not create the debugfs file for IPC3 at all as it is not applicable.

With IPC4 some vendors/platforms might not support loadable libraries and
the fw_lib_prefix is left to NULL to indicate this.
Handle such case with allocating "Not supported" string.

17f4041244 ASoC: SOF: debug: show firmware/topology prefix/names
The SOF driver has multiple profiles to select firmware/topology
prefix/names depending on the platform and ipc_type, and each of those
fields can be overridden with kernel parameters. This results in some
cases in confusion on what configuration is actually used in a given
test.

We currently log the firmware and topology names in the kernel logs,
but there's been an ask to add the information in debugfs to simplify
test scripts used by developers and CI.

This isn't meant to be a stable ABI used by apps, changes will be
allowed as needed.

b30289e7fa ASoC: SOF: Fix runtime pm usage counter balance after fw exception
If the retain context is enabled we will unconditionally increment the
device's pm use count on each exception and when the drivers are unloaded
we do not correct this (as we don't know how many times we 'prevented
d3 entry').
Introduce a flag to make sure that we do not increment the use count more
than once and on module unload decrement the use count if needed to
balance it.

3de975862f ASoC: SOF: debug: conditionally bump runtime_pm counter on exceptions
When a firmware IPC error happens during a pm_runtime suspend, we
ignore the error and suspend anyways. However, the code
unconditionally increases the runtime_pm counter. This results in a
confusing configuration where the code will suspend, resume but never
suspend again due to the use of pm_runtime_get_noresume().

The intent of the counter increase was to prevent entry in D3, but if
that transition to D3 is already started it cannot be stopped. In
addition, there's no point in that case in trying to prevent anything,
the firmware error is handled and the next resume will re-initialize
the firmware completely.

This patch changes the logic to prevent suspend when the device is
pm_runtime active and has a use_count > 0.

856601e5a7 ASoC: SOF: remove const qualifier for 'struct snd_sof_dsp_ops'
Now that we start having multiple platforms with minor variants, the
use of the const qualifier for 'dsp_ops' is starting to be
sub-optimal: the structures are copied across platforms, with only a
couple of members that differ.

This patch removes the const qualifier without any functionality
changes, and adds an optional initialization callback. In follow-up
patches, the dsp_ops will revisited for Intel HDaudio platforms, with
the differences added programmatically over a common baseline.

3dc0d70917 ASoC: SOF: Convert the generic probe support to SOF client
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.
