ASoC: rsnd: dvc: make sure DVC soft reset
Renesas SCU (Sampling Rate Convert Unit) includes SRC/CTU/MIX/DVC, and these have similar register. xxxRSR (Software reset Register) is one of them. These xxxRSR need be set to 1 to 0 when software reset. Current rsnd driver has src.c / dvc.c, and we will have mix.c. It is readable if these have same named function. This patch adds rsnd_dvc_soft_reset() and make sure it Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Tested-by: Keita Kobayashi <keita.kobayashi.ym@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
