Signed-off-by: Jeffy Chen Reviewed-by: Matthias Kaehlcke Tested-by: Matthias Kaehlcke --- Changes in v5: None Changes in v4: None Changes in v3: Use compatible to match audio codecs -- Suggested-by Matthias Kaehlcke Changes in v2: Let rockchip,codec-names be a required property, because we plan to add more supported codecs to the fixed dai link list in the driver. sound/soc/rockchip/rk3399_gru_sound.c | 139 ++++++++++++++++++++++------------ 1 file changed, 91 insertions(+), 48 deletions(-) diff --git a/sound/soc/rockchip/rk3399_gru_sound.c b/sound/soc/rockchip/rk3399_gru_sound.c index 9b7e28703bfb..d532336871d7 100644 --- a/sound/soc/rockchip/rk3399_gru_sound.c +++ b/sound/soc/rockchip/rk3399_gru_sound.c @@ -235,14 +235,42 @@ static const struct snd_soc_ops rockchip_sound_da7219_ops = { .hw_params = rockchip_sound_da7219_hw_params, };
