[PATCH 1/5] ASoC: audio-graph: add graph_parse_node()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx>

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