From 0919a3acc0c87049a7d787c4b8b9e64bd7c59eb3 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Tue, 11 May 2021 10:17:07 +0900 Subject: [PATCH] ASoC: simple-card: add simple_parse_node() Original commit 59c35c44a9cf89a83a9 ("ASoC: simple-card: add simple_parse_node()") was reverted, and this is remake version. Parse dai/tdm/clk are common for both CPU/Codec node. This patch creates simple_parse_node() for it and share the code.
