Subject: [PATCH v2 09/14] ASoC: dt-bindings:: qcom,q6asm: convert to dtschema
Convert Qualcomm Audio Stream Manager (Q6ASM) bindings to DT schema.
Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>
---
Expected warning because the qcom,apr.yaml is being fixed in next commit:
Documentation/devicetree/bindings/sound/qcom,q6asm.example.dtb: apr: service@7: 'dais' does not match any of the regexes: '^.*@[0-9a-f]+$', 'pinctrl-[0-9]+'
From schema: /home/krzk/dev/linux/linux/Documentation/devicetree/bindings/soc/qcom/qcom,apr.yaml
Changes since v1:
1. New patch.
