Subject: [PATCH 05/10] ASoC: rsnd: handle DPCM converted rate/chan under core
Date: Tue, 6 Nov 2018 05:20:10 +0000	[thread overview]
Message-ID: <878t26x01y.wl-kuninori.morimoto.gx@renesas.com> (raw)
In-Reply-To: <87ftwex052.wl-kuninori.morimoto.gx@renesas.com>


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

converted rate/chan are handled each rated module, but
it will be used other module too.
For examle, converted channel is currently used for CTU,
but, it will be used for TDM Split mode, too.

This patch move/merge SRC/CTU hw_param under core.c
and handles converted rate/chan under rsnd_dai_stream.
