Subject: [PATCH v2 03/14] ASoC: simple-card-utils: add asoc_graph_is_ports0()
Date: 20 Jul 2021 10:39:52 +0900 [thread overview]
Message-ID: <875yx5wyon.wl-kuninori.morimoto.gx@renesas.com> (raw)
In-Reply-To: <87a6mhwyqn.wl-kuninori.morimoto.gx@renesas.com>
From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>
audio-graph-card2 will support DPCM/Multi/Codec2Codec,
and these will use almost same DT settings which uses
ports0 and ports1.
This patch adds asoc_graph_is_ports0() which checks
port is under port0 or not.
