[PATCH 0/7] qrb4210-rb2: add HDMI audio playback support
First time I am doing anything like this. This series adds mising pieces here and there to allow addition of sensible sound card in qrb4210-rb2.dts and enable HDMI audio playback there.
It is planned in future to add support for other outputs and capture -- analog audio support.
The series depends on Srini's sm4250 lpi pinctrl driver: c2e5a25e8d88 (pinctrl: qcom: Introduce SM4250 LPI pinctrl driver, 2024-06-22) 2ffa7a354662 (dt-bindings: pinctrl: qcom: Add SM4250 pinctrl, 2024-06-22) As far as I understood it was already accepted and will go through pinctrl tree.

Add apr (asynchronous packet router) node and its associated services required to enable audio on QRB4210 RB2 platform. Also, add an empty sound{} device node. This allows board dts files to fill in required board specific properties.

This should be squashed with previous patch. You add one node of pinctrl with all of the default pins. You also miss soundwire and dmic pins.

Are they SoC-specific or board-specific? In the latter case it might be more suitable to move them to the board DT file.

Eh, now I am confused as well... There was so much talk about Srini's patchset that I assumed it is the same device. Why were you testing sm4250?
Best regards, Krzysztof

First time I am doing anything like this. This series adds mising pieces here and there to allow addition of sensible sound card in qrb4210-rb2.dts and enable HDMI audio playback there.
It is planned in future to add support for other outputs and capture -- analog audio support.
The series depends on Srini's sm4250 lpi pinctrl driver: c2e5a25e8d88 (pinctrl: qcom: Introduce SM4250 LPI pinctrl driver, 2024-06-22) 2ffa7a354662 (dt-bindings: pinctrl: qcom: Add SM4250 pinctrl, 2024-06-22) As far as I understood it was already accepted and will go through pinctrl tree.

My bot found new DTB warnings on the .dts files added or changed in this series.
Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings are fixed by another series. Ultimately, it is up to the platform maintainer whether these warnings are acceptable or not. No need to reply unless the platform maintainer has comments.
If you already ran DT checks and didn't see these error(s), then make sure dt-schema is up to date:
pip3 install dtschema --upgrade
New warnings running 'make CHECK_DTBS=y qcom/qrb4210-rb2.dtb' for 20240628010715.438471-1-alexey.klimov@linaro.org:
