Commit dc31e741 ("ASoC: topology: ABI - Add the types for BE
DAI") introduced sound topology files version 5. Initially, this
change made the topology code incompatible with v4 topology files.
Backwards compatibility with v4 configuration files was
subsequently added with commit 288b8da7 ("ASoC: topology:
Support topology file of ABI v4").

Unfortunately, backwards compatibility was never fully implemented.

First, the manifest size in (Skylake) v4 configuration files is set
to 0, which causes manifest_new_ver() to bail out with error messages
similar to the following.

snd_soc_skl 0000:00:1f.3: ASoC: invalid manifest size
snd_soc_skl 0000:00:1f.3: tplg component load failed-22
snd_soc_skl 0000:00:1f.3: Failed to init topology!
snd_soc_skl 0000:00:1f.3: ASoC: failed to probe component -22

skl_n88l25_m98357a: probe of skl_n88l25_m98357a failed with error -22

After this problem is fixed, the following error message is seen instead.

snd_soc_skl 0000:00:1f.3: ASoC: old version of manifest
snd_soc_skl 0000:00:1f.3: Invalid descriptor token 1093938482

snd_soc_skl 0000:00:1f.3: tPlg component load failed-22

This message is seen because backwards compatibility for loading widgets
was never implemented.

The lack of audio support when running the upstream kernel on recent
Chromebooks has been reported in various forums, and can be traced back
to this problem. Attempts to fix the problem, usually by providing v5
configuration files, were only partially successful.

Let's implement backward compatibility properly to solve the problem
for good.

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"
}

This starts to handle probe deferrals on regulators and clocks
on the ASoC DAPM.

I came to this patch after audio stopped working on Ux500 ages
ago and I finally looked into it to see what is wrong. I had
messages like this in the console since a while back:

ab8500-codec.0: ASoC: Failed to request audioclk: -517
ab8500-codec.0: ASoC: Failed to create DAPM control audioclk
ab8500-codec.0: Failed to create new controls -12
snd-soc-mop500.0: ASoC: failed to instantiate card -12
snd-soc-mop500.0: Error: snd_soc_register_card failed (-12)!
snd-soc-mop500: probe of snd-soc-mop500.0 failed with error -12

Apparently because the widget table for the codec looks like
this (sound/soc/codecs/ab8500-codec.c):

static const struct snd_soc_dapm_widget ab8500_dapm_widgets[] = {

        /* Clocks */
        SND_SOC_DAPM_CLOCK_SUPPLY("audioclk"),

        /* Regulators */
        SND_SOC_DAPM_REGULATOR_SUPPLY("V-AUD", 0, 0),
        SND_SOC_DAPM_REGULATOR_SUPPLY("V-AMIC1", 0, 0),
        SND_SOC_DAPM_REGULATOR_SUPPLY("V-AMIC2", 0, 0),
        SND_SOC_DAPM_REGULATOR_SUPPLY("V-DMIC", 0, 0),

So when we call snd_soc_register_codec() and any of these widgets
get a deferred probe we do not get an -EPROBE_DEFER (-517) back as
we should and instead we just fail. Apparently the code assumes
that clocks and regulators must be available at this point and
not defer.

After this patch it rather looks like this:

ab8500-codec.0: Failed to create new controls -517
snd-soc-mop500.0: ASoC: failed to instantiate card -517
snd-soc-mop500.0: Error: snd_soc_register_card failed (-517)!
(...)
abx500-clk.0: registered clocks for ab850x
snd-soc-mop500.0: ab8500-codec-dai.0 <-> ux500-msp-i2s.1 mapping ok
snd-soc-mop500.0: ab8500-codec-dai.1 <-> ux500-msp-i2s.3 mapping ok

I'm pretty happy about the patch as it it, but I'm a bit
uncertain on how to proceed: there are a lot of users of the
external functions snd_soc_dapm_new_control() (111 sites)
and that will now return an occassional error pointer, which
is not handled in the calling sites.

I want an indication from the maintainers whether I should just
go in and augment all these call sites, or if deferred probe
is frowned upon when it leads to this much overhead.

I could not figure out which of the valid types would be appropriate
here, so this sets it to '0', which is invalid but at least well-defined
here. There is probably a better way to address the issue.
