But the existing solution already works for Broadwell, see the alsa-lib config: `alsa-lib/src/conf/topology/broadwell/broadwell.conf` This commit provides the backwards-compatible solution to fix this misuse.

If anyone has any objections, please let me know. ------------------ From: Kirill Marinushkin [ Upstream commit 933e1c4a667103c4d10ebdc9505a0a6abd8c3fbd ] Clock gating parameter is a part of `dai_fmt`. It is supported by `alsa-lib` when creating a topology binary file, but ignored by kernel when loading this topology file. After applying this commit, the clock gating parameter is not ignored any more. This solution is backwards compatible. The existing behaviour is not broken, because by default the parameter value is 0 and is ignored. 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 For example, the following config, based on alsa-lib/src/conf/topology/broadwell/broadwell.conf, is now supported: ~~~~ SectionHWConfig."CodecHWConfig" { id "1" format "I2S" # physical audio format. pm_gate_clocks "true" # clock can be gated } SectionLink."Codec" { # used for binding to the physical link id "0" hw_configs [ "CodecHWConfig" ] default_hw_conf_id "1" } ~~~~ Signed-off-by: Kirill Marinushkin Reviewed-by: Pierre-Louis Bossart Cc: Jaroslav Kysela Cc: Takashi Iwai Cc: Mark Brown Cc: Pan Xiuli Cc: Liam Girdwood Cc: linux-kernel@vger.kernel.org Cc: alsa-devel@alsa-project.org Signed-off-by: Mark Brown Signed-off-by: Sasha Levin Signed-off-by: Greg Kroah-Hartman --- include/uapi/sound/asoc.h | 7 ++++++- sound/soc/soc-topology.c | 7 +++++++ 2 files changed, 13 insertions(+), 1 deletion(-) --- 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. */ @@ -324,7 +329,7 @@ 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; /* SND_SOC_TPLG_BCLK_ value */ --- a/sound/soc/soc-topology.c +++ b/sound/soc/soc-topology.c @@ -1997,6 +1997,13 @@ static void set_link_hw_format(struct sn link->dai_fmt = hw_config->fmt & SND_SOC_DAIFMT_FORMAT_MASK; + /* clock gating */ + if (hw_config->clock_gated == SND_SOC_TPLG_DAI_CLK_GATE_GATED) + link->dai_fmt |= SND_SOC_DAIFMT_GATED; + else if (hw_config->clock_gated == + SND_SOC_TPLG_DAI_CLK_GATE_CONT) + link->dai_fmt |= SND_SOC_DAIFMT_CONT; + /* clock signal polarity */ invert_bclk = hw_config->invert_bclk; invert_fsync = hw_config->invert_fsync;
