ASoC: rsnd: rsnd_mod controls clock
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 Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
