Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>:
The current version of delay reporting code can report incorrect
values when paired with a firmware which enables this feature.
Unfortunately there are several smaller issues that needed to be addressed
to correct the behavior:
Wrong information was used for the host side of counter
For MTL/LNL used incorrect (in a sense that it was verified only on MTL)
link side counter function.
The link side counter needs compensation logic if pause/resume is used.
The offset values were not refreshed from firmware.
Finally, not strictly connected, but the ALSA buffer size needs to be
constrained to avoid constant xrun from media players (like mpv)
The series applies cleanly for 6.9 and 6.8.y stable, but older stable
would need manual backport, but it is questionable if it is needed as
MTL/LNL is missing features.
When the Linear Link Position is not available in firmware SRAM window we
use the host accessible position registers to read it.
The address of the PPLCLLPL/U registers depend on the number of streams
(playback+capture).
At probe time the pplc_addr is calculated for each stream and we can use
it to read the LLP without the need of address re-calculation.
Set the get_stream_position callback in sof_hda_common_ops for all
platforms:
The callback is used for IPC4 delay calculations only but the register is
a generic HDA register, not tied to any specific IPC version.

Merge series from Cezary Rojewski <cezary.rojewski@intel.com>:
The avs-driver continues to be utilized on more recent Intel machines.
As TGL-based (cAVS 2.5) e.g.: RPL, inherit most of the functionality
from previous platforms:
SKL <- APL <- CNL <- ICL <- TGL
rather than putting everything into a single file, the platform-specific
bits are split into cnl/icl/tgl.c files instead. Makes the division clear
and code easier to maintain.
Layout of the patchset:
First are two changes combined together address the sound-clipping
problem, present when only one stream is running - specifically one
CAPTURE stream.
Follow up is naming-scheme adjustment for some of the existing functions
what improves code incohesiveness. As existing IPC/IRQ code operates
solely on cAVS 1.5 architecture, it needs no abstraction. The situation
changes when newer platforms come into the picture. Thus the next two
patches abstract the existing IPC/IRQ handlers so that majority of the
common code can be re-used.
The ICCMAX change stands out a bit - the AudioDSP firmware loading
procedure differs on ICL-based platforms (and onwards) and having a
separate commit makes the situation clear to the developers who are
going to support the solution from LTS perspective. For that reason
I decided not to merge it into the commit introducing the icl.c file.
The CHAIN_DMA IPC needs the number of playback streams as a start
offset for the dma_id of a capture stream.
This offset can be retrieved on Intel platforms from the GCAP
information, and stored in the sof_ipc4_fw_data structure.
One could argue that the fields added are not really dependent on any
firmware definitions but rather on hardware capabilities, but they are
required for the IPC CHAIN_DMA definitions so adding them in
ipc4_fw_data isn't completely silly.
The CHAIN_DMA IPC is currently only functional on Intel HDaudio DMAs,
and gated by the snd_sof_is_chain_dma_supported() helper.

The currently used paths and firmware name reflects the reference firmware
convention:
default_fw_path: intel/avs/{platform_name}
default_lib_path: intel/avs-lib/{platform_name}
default_tplg_path: intel/avs-tplg
default_fw_filename: dsp_basefw.bin
The SOF supports building the firmware for cAVS2.5 platforms using IPC4 and
it is the preferred IPC4 implementation to be used on these devices.
Change the paths and firmware names to reflect this:
default_fw_path: intel/sof-ipc4/{platform_name}
default_lib_path: intel/sof-ipc4-lib/{platform_name}
default_tplg_path: intel/sof-ipc4-tplg

ASoC: Updates for v6.8
This is a relatively quiet release, there's a lot of driver specific
changes and the usual high level of activity in the SOF core but the
one big core change was Mormioto-san's work to support more N:M
CPU:CODEC mapping cases. Highlights include:
- Enhanced support for N:M CPU:CODEC mappings in the core and in
audio-graph-card2.
- Support for falling back to older SOF IPC versions where firmware for
new versions is not available.
- Support for notification of control changes generated by SOF firmware
with IPC4.
- Device tree support for describing parts of the card which can be
active over suspend (for very low power playback or wake word use
cases).
- ACPI parsing support for the ES83xx driver, reducing the number of
quirks neede for x86 systems.
- Support for more AMD and Intel systems, NXP i.MX8m MICFIL, Qualcomm
SM8250, SM8550, SM8650 and X1E80100.
- Removal of Freescale MPC8610 support, the SoC is no longer supported
by Linux.
The current code flow is:
1. snd_hdac_device_register()
2. set parameters needed by the hdac driver
3. request_codec_module()
the hdac driver is probed at this point
During boot the codec drivers are not loaded when the hdac device is
registered, it is going to be probed later when loading the codec module,
which point the parameters are set.
On module remove/insert
rmmod snd_sof_pci_intel_tgl
modprobe snd_sof_pci_intel_tgl
The codec module remains loaded and the driver will be probed when the
hdac device is created right away, before the parameters for the driver
has been configured:
1. snd_hdac_device_register()
the hdac driver is probed at this point
2. set parameters needed by the hdac driver
3. request_codec_module()
will be a NOP as the module is already loaded
Move the snd_hdac_device_register() later, to be done right before
requesting the codec module to make sure that the parameters are all set
before the device is created:
1. set parameters needed by the hdac driver
2. snd_hdac_device_register()
3. request_codec_module()
This way at the hdac driver probe all parameters will be set in all cases.

ASoC: Updates for v6.7
This is quite a large set of changes but mostly due to API cleanups and
in driver specific ways rather than due to anything subsystem wide.
Highlights include:
- Standardisation of API prefixes on snd_soc_, removing asoc_.
- GPIO API usage improvements.
- Support for HDA patches.
- Lots of work on SOF, including crash dump support.
- Support for AMD platforms with es83xx, Awinc AT87390, many Intel
platforms, many Mediatek platforms, Qualcomm SM6115, Richtek RTQ9128
and Texas Instruments TAS575x.
[ the merge conflicts around SOF Intel HD-audio and CS35L41 subcodec
drivers are resolved here -- tiwai ]
In the existing IPC support, the reply to each IPC message is handled in
an IRQ thread. The assumption is that the IRQ thread is scheduled without
significant delays.
On an experimental (iow, buggy) kernel, the IRQ thread dealing with the
reply to the last IPC message before powering-down the DSP can be delayed
by several seconds. The IRQ thread will proceed with register accesses
after the DSP is powered-down which results in a kernel crash.
While the bug which causes the delay is not in the audio stack, we must
handle such cases with defensive programming to avoid such crashes.
Call synchronize_irq() before proceeding to power down the DSP to make
sure that no irq thread is pending execution.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
The SOF platform drivers all use either sof_of_remove() or
sof_acpi_remove() which both return zero unconditionally. Change these
functions to return void and the drivers to use .remove_new(). There is
no semantical change.

Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>:
When a firmware crashes it creats a panic information into a telemetry
slot. The panic format is defined by Zephyr, includes stack and
additional information to help to identify the reason for the crash.
Part of the firmware exception handling the firmware also sends an
EXCEPTION_CAUGHT notification.
This series implements the kernel side handling of the exception: print
information into the kernel log export the whole telemetry slot to user
space for tools extract additional information from the panic dump.
