From 8f7f298a333761a528e103cda3b42f3a416ad1ee Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Wed, 20 Mar 2019 13:56:36 +0900 Subject: [PATCH] ASoC: simple-card-utils: separate asoc_simple_card_parse_dai() The difference between simple-card / audio-graph are just using OF graph style, or not. In other words, other things should be same. This means, simple-card/audio-graph common functions should be implemented at simple-card-utils, and its own functions should be implemented at each files. Current simple-card / audio-graph are using asoc_simple_card_parse_dai() which is different implementation. But, these are implemanted at simple-card-utils. It should be implemanted at each files. This patch separate these into each files.
