Convert Qualcomm Audio Stream Manager (Q6ASM) bindings to DT schema. Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx> --- 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.
