[PATCH v2 00/11] ADSP for SDM670 and sound on Google Pixel 3a

[PATCH v2 00/11] ADSP for SDM670 and sound on Google Pixel 3a

[Richard Acayan]

This series adds a user for the SDM660 sound support code [1]. It also
adds the ADSP remoteproc for SDM670.

[1] https://lore.kernel.org/r/20260730174353.108023-1-mailingradian@gmail.com

Changes since v1 (https://lore.kernel.org/r/20260922015801.32373-1-mailingradian@gmail.com):
- squashed sound card and device-specific codec config (11/11)
- converted to fallback compatible (4/11)
- added compatible for WCD digital codec (5/11, 10/11)
- removed sleepstate comment (7/11)
- sorted subnodes of dai link (11/11)
- add review tags (1-3/11)

[PATCH v2 01/11] dt-bindings: soc: qcom,smp2p: add sleepstate support

[Richard Acayan]

The sleepstate entry is used by Qualcomm sensor DSPs to control
suspend/resume operations. Even though there is no full support for
sleep states, initialization of the entry is still necessary for some
DSPs, notably the sensors-bearing ADSP on the Pixel 3a (SDM670 SoC).
Allow sleepstates to be declared in the device tree so they can be
initialized.

compatible for it, with the same data as SDM845 since the driver

[PATCH v2 07/11] arm64: dts: qcom: sdm670: add adsp

[Richard Acayan]

The Audio DSP (Digital Signal Processor) is responsible for audio and
sensors on SDM670. Add this, along with the SMP2P nodes used to
communicate with it.

The sleep state is included to prevent the following crash:

    qcom_q6v5_pas remoteproc-adsp: fatal error received: err_qdi.c:450:EF:sensor_process:1:sar.cc:27:chre_utils fatal

Otherwise, it is unused.

Author: Richard Acayan <mailingradian@gmail.com>

dt-bindings: remoteproc: qcom: adsp: Add SDM670 ADSP compatible

The commit adds the SDM670 ADSP compatible string to the qcom,adsp binding.
It splits the compatible property into a oneOf block to allow the SDM670
compatible to fallback to SDM845.

[Severity: Medium]
Does adding qcom,sdm670-adsp-pas to this standalone enum branch bypass the
fallback requirement?

Because oneOf only requires a single branch to match, a device tree node
specifying only "qcom,sdm670-adsp-pas" matches this enum branch and passes
schema validation.

This bypasses the fallback enforcement in the items branch below, allowing
DTS nodes to be introduced without the required fallback string. Without
the fallback string, older kernels may fail to probe the device.

[Severity: Medium]
Will this cause problems for other boards that include this generic PMIC
file but have different hardware wiring?

These physical wiring properties (qcom,hphl-jack-type-normally-open,
qcom,gnd-jack-type-normally-open, qcom,micbias2-ext-cap) seem like they
should be placed in board-specific .dts files rather than a generic common
.dtsi.

Other boards with differently wired jacks (e.g., normally-closed) or lacking
an external capacitor will inherit these settings, which could lead to
inverted headphone detection or broken microphones.

> +			sound-name-prefix = "Analog";

[Severity: Low]
Is this sound-name-prefix property supported by the dt-binding schema?

It appears that the dt-binding schema for this codec
(Documentation/devicetree/bindings/sound/qcom,pm8916-wcd-analog-codec.yaml)
enforces additionalProperties: false and does not define sound-name-prefix.
Adding it here will likely cause a dtbs_check validation failure.

[Severity: Medium]
Is the `qcom,non-secure-domain` property missing here?

During probe, the driver checks for `qcom,non-secure-domain`. When it is
missing, the driver defaults `secure_dsp` to true, creating a 
`/dev/fastrpc-adsp-secure` device node instead of the standard 
`/dev/fastrpc-adsp`.

Does this break standard userspace audio and sensor applications that expect
the non-secure device node for standard ADSP compute tasks?

[Severity: Medium]
Is it safe to supply a dummy 1.536 MHz bit clock as the AHB interconnect
clock here?

The underlying digital codec driver unconditionally requires the AHB clock
in msm8916_wcd_digital_get_clks():

	priv->ahbclk = devm_clk_get(dev, "ahbix-clk");
	if (IS_ERR(priv->ahbclk)) {
		dev_err(dev, "failed to get ahbix clk\n");
		return PTR_ERR(priv->ahbclk);
	}

By satisfying "ahbix-clk" with a dummy fixed clock, the hardware state is
misrepresented. The driver will successfully "enable" this dummy clock
and proceed to access registers.

If the actual AHB clock is gated by firmware or another driver, could
this result in register accesses without the bus being clocked,
triggering a bus stall and a synchronous external abort?

Thanks!

[05/11] ASoC: dt-bindings: msm8916-digital-codec: Add SDM670 compatible
        https://git.kernel.org/broonie/sound/c/5b81127873ae

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
