Subject: [PATCH v4 11/15] ASoC: dt-bindings: qcom,q6adm: convert to dtschema
Convert Qualcomm Audio Device Manager (Q6ADM) bindings to DT schema.
The original bindings documented:
1. APR service node with compatibles: "qcom,q6adm" and
"qcom,q6adm-v<MAJOR-NUMBER>.<MINOR-NUMBER>",
2. Routing child node with compatible "qcom,q6adm-routing".
The conversion entirely drops (1) because the compatible is already
documented in bindings/soc/qcom/qcom,apr.yaml. The
"qcom,q6adm-v<MAJOR-NUMBER>.<MINOR-NUMBER>" on the other hand is not
used at all - neither in existing DTS, nor in downstream sources - so
versions seems to be fully auto-detectable.
Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>

Changes since v3:
1. New patch.
