[PATCH 0/2] qcom: add Asus Vivobook 16 X1607QA DT + LPASS audio clock retry

[yass27106]

Hi,

Two patches against v7.4-rc1 (also sent as pull request 1439 to
qualcomm-linux/kernel, and to the Ubuntu kernel team):

[PATCH 1/2] arm64: dts: qcom: add device tree for Asus Vivobook 16 X1607QA
  Initial DT for this Snapdragon X X1P-42-100 (purwa) laptop, including
  sound nodes (WSA8845 speakers, WCD938x codec via SoundWire).

[PATCH 2/2] ASoC: qcom: lpass macro / soundwire: retry deferred clock acquisition
  The LPASS WSA/RX/TX/VA macro and Qualcomm SoundWire drivers request
  clocks whose providers (va-macro fsgen, q6prm clock controller under
  the ADSP GPR service) can register after the consumers probe.
  Clock-provider registration does not trigger deferred-probe retries,
  so consumers stay deferred indefinitely. Adds a bounded retry
  (60 x 500 ms) around the devm_clk_get calls in these drivers.

Both pass scripts/checkpatch.pl with no errors; the DTB builds cleanly.
The DT addition is for the v7.5 merge window; patch 2 is a fix that could
go into v7.4-rc if the maintainers see fit.

You've not provided a Signed-off-by for this so I can't do anything with
it, please see Documentation/process/submitting-patches.rst for details
on what this is and why it's important.

There's also no changelog here.

This obviously isn't something that should be open coded in drivers,
this is going to be happening all over the place.  The clock API and
driver core need to be adjusted so that we trigger deferred probe runs
when new resources appear.

Please run scripts/checkpatch.pl on the patches and fix reported
warnings. After that, run also 'scripts/checkpatch.pl --strict' on the
patches and (probably) fix more warnings. Some warnings can be ignored,
especially from --strict run, but the code here looks like it needs a
fix. Feel free to get in touch if the warning is not clear.

Please read submitting patches document to understand DCO.

Looks like completely corrupted anonymous patch.

Re: [PATCH 1/2] arm64: dts: qcom: add device tree for Asus Vivobook 16 X1607QA — v2 series

[Daniel Carter]

Hi Krzysztof, hi all,

v2 of the series, addressing your review of v1:

- The binding documentation is now a separate patch (dt-bindings first),
  as required by Documentation/devicetree/bindings/submitting-patches.rst.
- The board compatible 'asus,vivobook-16-x1607qa' is documented in
  Documentation/devicetree/bindings/arm/qcom.yaml.
- scripts/checkpatch.pl passes with no errors on all patches; --strict
  leaves only the MAINTAINERS note on the new-file patch.
- The DCO sign-off is now a real-name sign-off; apologies for the
  pseudonymous v1.

Series:
[1/3] dt-bindings: qcom: document Asus Vivobook 16 X1607QA
[2/3] arm64: dts: qcom: add device tree for Asus Vivobook 16 X1607QA
[3/3] ASoC: qcom: lpass macro / soundwire: retry deferred clock acquisition

Also open as pull request 1439 at github.com/qualcomm-linux/kernel.

Best regards,
Daniel Carter

Re: [PATCH v2 1/3] arm64: dts: qcom: add device tree for Asus Vivobook 16 X1607QA - v3 series

[Daniel Carter]

Hi Krzysztof, hi all,

v3 of the series, addressing the Sashiko review of v2:

- arm64/dts: add /delete-node/ for pmc8380_6, pmc8380_6_thermal and
  pmc8380_6_die_temp, which are unpopulated on the X1P-42-100
  (matching the Vivobook S15 device tree).
- arm64/dts: add the missing qcom,dmic-sample-rate and
  vdd-micb-supply properties on lpass_vamacro.
- arm64/dts: add the -el2 composite device tree blob target and fix
  the Makefile alphabetical ordering.
- arm64/dts: cosmetic cleanups (single root node, gpu_zap_shader used
  directly, sorted label overrides).
- ASoC/soundwire: mark the LPASS macro and Qualcomm SoundWire drivers
  PROBE_PREFER_ASYNCHRONOUS so the bounded clock-acquisition retry
  does not block the probe of the clock supplier on the single
  sequential probe thread, and share the retry helpers through
  lpass-macro-common.h instead of duplicating them per driver.
- soundwire: check clk_prepare_enable() return values (separate
  patch; pre-existing issue in the driver).

Series:
[1/4] dt-bindings: qcom: document Asus Vivobook 16 X1607QA
[2/4] arm64: dts: qcom: add device tree for Asus Vivobook 16 X1607QA
[3/4] ASoC: qcom: lpass macro / soundwire: asynchronous probe with clock retry
[4/4] soundwire: qcom: check clk_prepare_enable() return values

Also open as pull request 1439 at github.com/qualcomm-linux/kernel.

Best regards,
Daniel Carter

[PATCH v3 2/4] arm64: dts: qcom: add device tree for Asus Vivobook 16 X1607QA

[Daniel Carter]

Add initial device tree for the Asus Vivobook 16 X1607QA laptop
with the Snapdragon X X1P-42-100 (purwa) SoC, based on the Vivobook
S15. Includes the sound nodes (WSA8845 speakers, WCD938x codec via
SoundWire), the VA macro with its DMIC sample rate and mic bias
supply, and the EL2 device tree blob target.

[PATCH v3 3/4] ASoC: qcom: lpass macro / soundwire: asynchronous probe with clock retry

[Daniel Carter]

The LPASS WSA/RX/TX/VA macro and Qualcomm SoundWire drivers request
clocks whose providers (va-macro fsgen, the q6prm clock controller
under the ADSP GPR service) can register after the consumers probe.
Clock-provider registration does not trigger deferred-probe retries,
so consumers stay deferred indefinitely.

Add a bounded retry (60 x 500 ms) around the clock acquisition in
these drivers, share the retry helpers through lpass-macro-common.h,
and mark the drivers PROBE_PREFER_ASYNCHRONOUS so a retrying consumer
does not block the probe of the clock supplier it is waiting for.

[PATCH v3 4/4] soundwire: qcom: check clk_prepare_enable() return values

[Daniel Carter]

clk_prepare_enable() can fail; unchecked, the driver proceeds to
touch registers with the interface clock off, which aborts on arm64.
Check the return value in the interrupt handler, in probe and in the
runtime resume path, re-enabling the wake IRQ on the resume error
path.

Please don't send new patches in reply to old patches or serieses, this
makes it harder for both people and tools to understand what is going
on - it can bury things in mailboxes and make it difficult to keep track
of what current patches are, both for the new patches and the old ones.

You might want to look at b4 to send the patches, especially it's web
submission endpoint which avoids having to configure mail:

Re: [PATCH v3 1/4] dt-bindings: qcom: document Asus Vivobook 16 X1607QA

Hi Mark,

Thanks for the review.

Understood on threading - this was a reply in the old thread rather
than a fresh one; the next revision will go out as a new thread. I'll
set up b4 before then.

On the clock retry itself: agreed that the right fix is in the driver
core / clock API so that deferred-probe runs are retriggered when new
resources appear, rather than open-coding bounded retries in drivers.
That is a much larger change than I can make alone, so my intention
with this series was a stopgap for this laptop: without the retry the
macro and SoundWire drivers stay deferred forever on X1P42100 because
their clock providers register late.

Would you prefer that patch be dropped from this series until the core
side is sorted, or is a bounded retry acceptable in the interim? Happy
to follow either direction - the device tree patches (1/4 and 2/4) are
independent of it.

Best regards,
Daniel Carter

I'm not going to take such a massive workaround as that unless
absolutely needed.
