From 90be711e23f7c7ee7b3d6a6e5aa7ee9bab321f2e Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Tue, 8 Aug 2017 06:18:10 +0000 Subject: [PATCH] ASoC: use snd_soc_rtdcom_add() and convert to consistent operation Basically, current ALSA SoC framework is based on CPU/Codec/Platform, but its operation doesn't have consistent. Thus, source code was unreadable, and difficult to understand. This patch connects each component (= CPU/Codec/Platform) to rtd by using snd_soc_rtdcom_add(), and convert uneven operations to consistent operation.
