From cdd3b8daf26e5eb2e97b6a37dfdb83597bcbdc52 Mon Sep 17 00:00:00 2001 From: Stephan Gerhold Date: Wed, 26 Aug 2020 11:51:40 +0200 Subject: 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".
