The Acer Aspire Go 15 (AG15-21P, board MDC Herbag2_MDU) has two PDM
DMICs connected to the ACP. The BIOS does not set the AcpDmicConnected
_DSD property, so the acp6x machine driver never registers the DMIC
card. The existing Herbag_MDU entry does not match this board name, so
add a DMI quirk for it.
Tested on BIOS V1.11: the acp6x DMIC capture device is registered and
records audio on both channels.

The Lenovo V15 G6 ARP (product name 83UU) uses the ACP6x PDM interface
for its internal digital microphone array. Its firmware exposes neither
the AcpDmicConnected _DSD property nor the _WOV method, so acp6x_probe()
falls through to the DMI check and returns -ENODEV, leaving
acp_yc_mach.0 unbound and no capture device registered.
Add a DMI quirk entry for this model. With it, the machine driver binds
and the DMIC capture device is created:
acp_yc_mach acp_yc_mach.0: Enabling ACP DMIC support via DMI
card 2: acp6x [acp6x], device 0: DMIC capture dmic-hifi-0
Capture was verified working with arecord and PipeWire.

A fairly big batch of fixes that came in during the merge window.
There's a lot of quirks for x86 systems and a bunch of driver specific
fixes, the most critical being the fixes for Tegra's register
definitions. It turned out that they had been relying on the regmap
default handling bugs that were fixed in v7.2 and so audio was fairly
badly broken, unfortunately the issue wasn't noticed in time for
release.

ASoC: Fixes for v7.3
A fairly big batch of fixes that came in during the merge window.
There's a lot of quirks for x86 systems and a bunch of driver specific
fixes, the most critical being the fixes for Tegra's register
definitions. It turned out that they had been relying on the regmap

A very busy release, a combination of a lot of new device work and more
people than usual doing various subsystem wide improvements in the code.
The main subsystem level change is the work Morimoto-san has been doing
to get automatic DAI format selection more widely deployed, and even
that is largely changes in the drivers to enable use of the feature
rather than framework work.
- Conversions of a lot of drivers to use the automatic DAI format
selection code from Morimoto-san.
- Many fixes and code improvements from bui duc phuc and Morimoto-san.
- Fixes for ordering problems in register default tables from Peter
Ujfalusi.
- Changes to use auto-cleanup for firmware to improve robustness from
Takashi Iwai.
- Support for firmware on more Awinc devices.
- Many changes in the Qualcomm driver stack, mostly around new platform
support.
- Support for AMD ACP7.B/F, Cirrus Logic CS35L62, Loongson 2K0300,
Meson GX formatter and interface, Qualcomm LPI MI2S, SM8475 and
WSA855 and Realtek RT1321 VA1/2 and RT766/7.

Ville Saarinen <wiza@saarinenkoti.fi> says:
The HP OmniBook X Flip 14-kc0xxx (board 8EA1, Strix Point, ACP 7.2) has no
usable audio on mainline at all. Its BIOS reports an ACP configuration flag
of FLAG_AMD_LEGACY_ONLY_DMIC, which binds the legacy ACP driver and
registers a PDM-only card, so the SoundWire links are never scanned. The
two TAS2783 speaker amplifiers on link 0 and the RT712-VB jack codec on
link 1 never enumerate, and the machine has no playback path whatsoever.
Patch 1 adds a DMI quirk overriding the flag so snd_pci_ps probes. Patch 2
adds the machine entry describing the link topology.
With both applied the card comes up and every path on the machine works:
internal speakers, headphone jack with detection, headset microphone and
the internal DMIC array. Two further patches are needed for the speakers
to render stereo rather than mono, and to survive a system resume; those
are in the TAS2783 codec driver and are being sent separately to the TI
maintainers, since they have no build dependency on this pair.
Related reports for the same root cause on other machines:
- kernel bugzilla #221226 (ASUS Zenbook S16)
- CachyOS linux-cachyos#820 (HP OmniBook X Flip 16, board 8EA2 -- the
sibling board, which would need its own entry; I have no access to
one and have not added it)
Tested on the affected machine only. I do not have any other ACP 7.2
board, so the gating on patch 2 is written to be conservative rather than
broad.
Testing
=======
The hardware testing was done on v7.1.6, where an equivalent version of
this pair is what makes audio work on the machine. Against the master
commit named below, both patches have been compile-tested only (gcc, W=1,
no new warnings, no new external symbol references).
Patch 2 has been reworked slightly relative to the tested build: the
RT712-VB entry now reuses the existing jack_dmic_endpoints array, which
already describes exactly the AIF1 jack + AIF3 DMIC pairing this board
needs, instead of adding a second identical copy of it. That was a
mechanical substitution, but it has not been through hardware.
Tool disclosure, per Documentation/process/generated-content.rst
================================================================
This work was done in extended interactive sessions with Claude (Anthropic,
model claude-opus-5) acting as a coding and debugging assistant, and a
substantial amount of the analysis and of the patch text originated with
it. Both patches carry an Assisted-by tag as described in
Documentation/process/coding-assistants.rst.
The division of work:
- The assistant read the DMI data and ACP configuration flag off the
running machine, identified the flag override as the fix, derived the
SoundWire topology from the enumerated peripherals, and drafted both
patches and both changelogs.
- I ran everything that needed root or physical access, rebooted into
each build, and did the listening tests. The left/right ordering in
patch 2 is set by the order of the two amplifier entries; the first
version had the sides reversed and that was caught by ear, not by the
assistant.
- No single prompt generated these patches. The session was iterative
over roughly a day: inspect state, form a hypothesis, build, reboot,
measure, discard the hypothesis if the measurement disagreed. Several
confident intermediate conclusions were wrong and were only caught by
measurement.
I have reviewed both patches, I understand what they do, and I take
responsibility for them.

This was done entirely with mindless brute force, using

xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate

This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:
Single allocations: kmalloc(sizeof(TYPE), ...)
are replaced with: kmalloc_obj(TYPE, ...)
Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with: kmalloc_objs(TYPE, COUNT, ...)
Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...)
