[alsa-devel] [PATCH 08/20] ASoC: rsnd: synchronize SSI start/stop sequence between PIO/DMA mode

[Kuninori Morimoto]

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

Current SSI start/stop sequence is different between PIO/DMA mode,
but, almost all are same. this patch synchronize it.
It will be shared in the future.
