From 2af69581e1b11152bc42f1122d3c16e177bd77cf Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Mon, 23 Mar 2020 14:16:57 +0900 Subject: ASoC: soc-core: add asoc_rtd_to_cpu/codec() macro Now, snd_soc_pcm_runtime supports multi cpu_dai/codec_dai. It still has cpu_dai/codec_dai for single DAI, and has cpu_dais/codec_dais for multi DAIs. dais = [][][][][][][][][][][][][][][][][][] ^cpu_dais ^codec_dais |--- num_cpus ---|--- num_codecs --| /* for multi DAIs */ rtd->cpu_dais = &rtd->dais[0]; rtd->codec_dais = &rtd->dais[dai_link->num_cpus]; /* for single DAI */ rtd->cpu_dai = rtd->cpu_dais[0]; rtd->codec_dai = rtd->codec_dais[0]; But, these can be replaced by dais. This patch adds asoc_rtd_to_cpu() / asoc_rtd_to_codec() macro for it.
