This patch makes SRC stop SRC.out only when stop timing. And it stops both SRC.out/SRC.in when quit timing Signed-off-by: Kuninori Morimoto Signed-off-by: Mark Brown --- diff --git a/sound/soc/sh/rcar/src.c b/sound/soc/sh/rcar/src.c index 513094ec2312..3f6993facf69 100644 --- a/sound/soc/sh/rcar/src.c +++ b/sound/soc/sh/rcar/src.c @@ -665,13 +665,27 @@ static int _rsnd_src_stop_gen2(struct rsnd_mod *mod) { rsnd_src_irq_disable_gen2(mod); - rsnd_mod_write(mod, SRC_CTRL, 0); + /* + * stop SRC output only + * see rsnd_src_quit_gen2 + */ + rsnd_mod_write(mod, SRC_CTRL, 0x01); rsnd_src_error_record_gen2(mod); return rsnd_src_stop(mod); } +static int rsnd_src_quit_gen2(struct rsnd_mod *mod, + struct rsnd_dai_stream *io, + struct rsnd_priv *priv) +{ + /* stop both out/in */ + rsnd_mod_write(mod, SRC_CTRL, 0); + + return 0; +} + static void __rsnd_src_interrupt_gen2(struct rsnd_mod *mod, struct rsnd_dai_stream *io) { @@ -943,7 +957,7 @@ static struct rsnd_mod_ops rsnd_src_gen2_ops = { .probe = rsnd_src_probe_gen2, .remove = rsnd_src_remove_gen2, .init = rsnd_src_init_gen2, - .quit = rsnd_src_quit, + .quit = rsnd_src_quit_gen2, .start = rsnd_src_start_gen2, .stop = rsnd_src_stop_gen2, .hw_params = rsnd_src_hw_params,
