From: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx> This patch adds Audio Graph Card2 Yaml bindings. It is similar to Audio Graph Card, but different. - audio-graph-card used "dais" to indicate DAI-links, audio-graph-card2 uses "links" to it. - audio-graph-card used "phandle" to indicate bitclock/frame-master, audio-graph-card2 uses flag to it. - audio-graph-card used "format" to indicate DAI format, audio-graph-card2 assumes CPU/Codec drivers have .get_fmt support.
