Subject: [PATCH 3/5] ASoC: simple-card: add simple_parse_node()
Date: 21 Apr 2021 14:45:48 +0900	[thread overview]
Message-ID: <87czuoi41f.wl-kuninori.morimoto.gx@renesas.com> (raw)
In-Reply-To: <87h7k0i437.wl-kuninori.morimoto.gx@renesas.com>


From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

Parse dai/tdm/clk are common for both CPU/Codec node.
This patch creates simple_parse_node() for it and share the code.
