From: Stephan Gerhold Date: Wed, 26 Aug 2020 09:51:40 +0000 (+0200) Subject: ASoC: dt-bindings: qcom: Document "aux-devs" property X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=cdd3b8daf26e5eb2e97b6a37dfdb83597bcbdc52;p=linux.git ASoC: dt-bindings: qcom: Document "aux-devs" property In some cases we need to probe additional audio components that do not appear as part of the DAI links specified in the device tree. Examples for this are auxiliary devices such as analog amplifiers or codecs. To make them work they need to be added as part of "aux-devs" and connected to some other audio component using the audio routes configurable using "(qcom,)audio-routing".
