From: Krzysztof Kozlowski Date: Sat, 10 Sep 2022 09:14:23 +0000 (+0200) Subject: ASoC: dt-bindings: qcom,q6asm: convert to dtschema X-Git-Tag: v6.1-rc5~4^2~17^2~102^2~5 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7b0ad4629d1fb719ae71a8f2968e8c6268ab1709;p=platform%2Fkernel%2Flinux-starfive.git ASoC: dt-bindings: qcom,q6asm: convert to dtschema Convert Qualcomm Audio Stream Manager (Q6ASM) bindings to DT schema. The original bindings documented: 1. APR service node with compatibles: "qcom,q6asm" and "qcom,q6asm-v.", 2. actual DAIs child node with compatible "qcom,q6asm-dais". The conversion entirely drops (1) because the compatible is already documented in bindings/soc/qcom/qcom,apr.yaml. The "qcom,q6asm-v." 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. Another change done in conversion is adding "iommus" property, which is already used in DTS and Linux driver.
