[alsa-devel] [PATCH 03/16] ASoC: rsnd: rsnd_mod controls clock

Thu Jan 15 09:03:22 CET 2015
From: Kuninori Morimoto <kuninori.morimoto.gx at renesas.com>
Current rsnd driver's mod (= ssi/src/dvc) have each own clk,
but, these are needed to start/stop each mod.
This patch adds struct clk in rsnd_mod, and start/stop these
via rsnd_mod_hw_start/stop() macro
