Therefore this commit adds the defines for this field. snd_soc_tplg_hw_config.clock_gated = 0 => no effect snd_soc_tplg_hw_config.clock_gated = 1 => SND_SOC_DAIFMT_GATED snd_soc_tplg_hw_config.clock_gated = 2 => SND_SOC_DAIFMT_CONT Signed-off-by: Kirill Marinushkin Cc: Takashi Sakamoto Cc: Jaroslav Kysela Cc: Takashi Iwai Cc: alsa-devel@alsa-project.org Cc: linux-kernel@vger.kernel.org --- include/uapi/sound/asoc.h | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) diff --git a/include/uapi/sound/asoc.h b/include/uapi/sound/asoc.h index 69c37ecbff7e..86d0599a6f13 100644 --- a/include/uapi/sound/asoc.h +++ b/include/uapi/sound/asoc.h @@ -139,6 +139,11 @@ #define SND_SOC_TPLG_DAI_FLGBIT_SYMMETRIC_CHANNELS (1 << 1) #define SND_SOC_TPLG_DAI_FLGBIT_SYMMETRIC_SAMPLEBITS (1 << 2) +/* DAI clock gating */ +#define SND_SOC_TPLG_DAI_CLK_GATE_UNDEFINED 0 +#define SND_SOC_TPLG_DAI_CLK_GATE_GATED 1 +#define SND_SOC_TPLG_DAI_CLK_GATE_CONT 2 + /* DAI physical PCM data formats. * Add new formats to the end of the list. */ @@ -312,7 +317,7 @@ struct snd_soc_tplg_hw_config { __le32 size; /* in bytes of this structure */ __le32 id; /* unique ID - - used to match */ __le32 fmt; /* SND_SOC_DAI_FORMAT_ format value */ - __u8 clock_gated; /* 1 if clock can be gated to save power */ + __u8 clock_gated; /* SND_SOC_TPLG_DAI_CLK_GATE_ value */ __u8 invert_bclk; /* 1 for inverted BCLK, 0 for normal */ __u8 invert_fsync; /* 1 for inverted frame clock, 0 for normal */ __u8 bclk_master; /* 1 for master of BCLK, 0 for slave */ -- 2.13.6
