[PATCH 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.

[PATCH 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.

[PATCH 06/11] 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.

commit 331a31ea9c73f1abc1441342a8c3c461afc91cb0
Author: Richard Acayan <mailingradian@gmail.com>

arm64: dts: qcom: pm660l: add analog audio codec

The PM660L analog audio codec (PMIC revision 4) controls the headphone
jack, and optionally the earpiece and speaker, at the vendor's decision.
Add the analog audio codec.

[Severity: Low]
Are these properties appropriate for a generic PMIC device tree include?

These properties describe external, board-specific physical hardware rather
than internal states of the PM660L PMIC. Including them in the shared .dtsi
applies these board specifics to all devices using this PMIC, which forces
boards with different headphone jack types or micbias wiring to use the Device
Tree /delete-property/ anti-pattern to unset them.

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

[Severity: Low]
Does this property violate the binding schema?

The device tree schema for qcom,pm8916-wcd-analog-codec.yaml has
additionalProperties: false, but it does not define sound-name-prefix
nor does it import a common schema (e.g. dai-common.yaml) that would permit
it. This will likely trigger a dtbs_check schema validation error.

[Severity: Medium]
Does this fastrpc node need the qcom,non-secure-domain property?

Without this property, the secure_dsp flag evaluates to true during driver
probe in drivers/misc/fastrpc.c. For the ADSP domain,
fastrpc_device_register() will then create only the fastrpc-adsp-secure
device node instead of fastrpc-adsp.

Will this cause standard userspace libraries to fail to open the DSP device
if they expect the non-secure node?

[Severity: Medium]
Is it semantically correct to model an AHB bus clock as an audio bit clock?

The msm8916-wcd-digital codec driver requests an AHB interconnect clock
("ahbix-clk") for its register space. This patch maps that requirement to
int_cdc_bclk, which is configured above as a 1.536MHz fixed clock (which
corresponds exactly to a 48kHz audio BCLK).

While this allows the driver to probe successfully because a dummy fixed-clock
returns 0 on clk_prepare_enable(), it misrepresents the hardware layout.

If the true AHB clock is abstracted, always-on, or managed elsewhere, shouldn't
it be mapped to the board's XO or a generic system clock rather than a fake bit
clock?

Maybe it would be better to combine with patch 8 (same /^.*:/ prefix),
if this is just about number of patches. Patch 9 is about as related as
patch 10.

You need to update constraints.

I'll do this next revision to avoid adding the constraints in the
bindings, but I think SDM845 will only have one specific compatible.
MSM8998 and SM8150 use different data than SDM845.

It's not magic, the driver registers it in the SMEM item, and the
ADSP likely looks it up and complains if it's missing. You can
drop this comment, since you already explained it in the commit
message.

This property is going away, please remove it

Please ensure 'status' is the last property with an \n before it

Please introduce a SoC-specific compatible for 670.
