[PATCH alsa-lib v4 0/4] alsa-lib: ASoC: topology: Improve hw_configs

[Kirill Marinushkin]

Hello Takashi,

This patch series waits since 20th of February, because it modifies UAPI headers
and should be done in sync with Linux and ALSA. I see that previously there was
no clear understanding, how to do this in sync.

We discussed with you on 02 Apr 2018, and you suggested the following steps:

Step 1. A person from Intel, who knows the topic (Pierre), adds his
"Reviewed-by" or "Acked-by" tags
Step 2. I clarify with Mark to apply the Linux part (different patch series)
Step 3. After that, I clarify with you to apply the ALSA part (this patch
series)

The step 1 is done. Old patches are reviewed by Pierre, so they have his
"Reviewed-by" tag. New patches are suggested by him, and we agreed on the
implementation, so they have his "Acked-by" tag.

The step 2 is done. Mark applied the corresponding part to his Linux tree [1].

Now we are on the step 3. If you don't have anything against this patch series,
please apply it to ALSA.

Best Regards,
Kirill

[PATCH alsa-lib v4 1/4] ASoC: topology: Fix bclk and fsync inversion in set_link_hw_format()

[Kirill Marinushkin]

The values of bclk and fsync are inverted WRT the codec. 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.
This commit goes in pair with the corresponding patch for linux.

[PATCH alsa-lib v4 2/4] ASoC: topology: Add missing clock gating parameter when parsing hw_configs

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"
}

[PATCH alsa-lib v4 3/4] ASoC: topology: Add definitions for mclk_direction values

[Kirill Marinushkin]

Current comment makes not clear the direction of mclk. Previously, similar
description caused a misunderstanding for bclk_master and fsync_master.

This commit solves the potential confusion the same way it is solved for
bclk_master and fsync_master.

[PATCH alsa-lib v4 4/4] ASoC: topology: Add alias conf parameter names for hw_configs

[Kirill Marinushkin]

Currently, some parameter names in conf differ from field names in struct.
These look like typos.

This commit suggests to add aliases for such parameters, so that the names
in conf are similar to names in struct. This solution is backwards
compatible.

If the difference between conf names and struct names is done on purpose -
this commit can be dropped.

Ideally, Mark should send the pull request for the uapi changes he
applied so that they are "fixated" before going further to user-space
patches.

But this topology change is no intrusive ABI breakage, so I applied
now as is.

Unfortunately that's a bit annoying to do now without using topic
branches...

Yeah, it didn't look like there was an actual dependency which was why I
didn't immediately push anything.
