Dan reported that smatch reports wrong size check and after analysis it
is confirmed that we are comparing wrong value: pointer size instead of
array size. However the check itself is problematic as in UAPI header
there are two fields:
struct snd_soc_tplg_enum_control {
(...)
char texts[SND_SOC_TPLG_NUM_TEXTS][SNDRV_CTL_ELEM_ID_NAME_MAXLEN];
__le32 values[SND_SOC_TPLG_NUM_TEXTS * SNDRV_CTL_ELEM_ID_NAME_MAXLEN / 4];
the texts field is for names and the values one for values assigned to
those named fields, after analysis it becomes clear that there is quite
a lot overhead values than we may possibly name. So instead of changing
check to ARRAY_SIZE(ec->values), as it was first suggested, use
hardcoded value of SND_SOC_TPLG_NUM_TEXTS.

soc_pcm_trigger() calls DAI/Component/Link trigger,
but some of them might be failed.
static int soc_pcm_trigger(...)
{
...
switch (cmd) {
case SNDRV_PCM_TRIGGER_START:
case SNDRV_PCM_TRIGGER_RESUME:
case SNDRV_PCM_TRIGGER_PAUSE_RELEASE:
ret = snd_soc_link_trigger(substream, cmd);
if (ret < 0)
break;
(*) ret = snd_soc_pcm_component_trigger(substream, cmd);
if (ret < 0)
break;
ret = snd_soc_pcm_dai_trigger(substream, cmd);
break;
case SNDRV_PCM_TRIGGER_STOP:
case SNDRV_PCM_TRIGGER_SUSPEND:
case SNDRV_PCM_TRIGGER_PAUSE_PUSH:
ret = snd_soc_pcm_dai_trigger(substream, cmd);
if (ret < 0)
break;
ret = snd_soc_pcm_component_trigger(substream, cmd);
if (ret < 0)
break;
ret = snd_soc_link_trigger(substream, cmd);
break;
}
...
}
For example, if soc_pcm_trigger() failed at (*) point,
we need to rollback previous succeeded trigger.
This patch adds trigger mark for DAI/Component/Link,
and do STOP if START/RESUME/PAUSE_RELEASE were failed.
Because it need to use new rollback parameter,
we need to modify DAI/Component/Link trigger functions in the same time.

dpcm_be_dai_trigger() is calling dpcm_do_trigger()
at each SNDRV_PCM_TRIGGER_xxx (1).
int dpcm_be_dai_trigger(...)
{
for_each_dpcm_be(fe, stream, dpcm) {
(B) ...
switch (cmd) {
case SNDRV_PCM_TRIGGER_START:
...
(1) ret = dpcm_do_trigger(...);
...
case SNDRV_PCM_TRIGGER_RESUME:
...
(1) ret = dpcm_do_trigger(...);
...
case SNDRV_PCM_TRIGGER_PAUSE_RELEASE:
...
(1) ret = dpcm_do_trigger(...);
...
case SNDRV_PCM_TRIGGER_STOP:
...
(1) ret = dpcm_do_trigger(...);
...
case SNDRV_PCM_TRIGGER_SUSPEND:
...
(1) ret = dpcm_do_trigger(...);
...
case SNDRV_PCM_TRIGGER_PAUSE_PUSH:
...
(1) ret = dpcm_do_trigger(...);
...
}
}
}
But it is just very verbose and duplicated function.
Because We can indicate dev_dbg() (A) at dpcm_be_dai_trigger() (B).
And dev_err() (C) is not needed because soc_pcm_trigger() itself
indicates error message when error.
static int dpcm_do_trigger(...)
{
int ret;
(A) dev_dbg(...);
ret = soc_pcm_trigger(substream, cmd);
if (ret < 0)
(C) dev_err(...);
return ret;
}
This patch replace dpcm_do_trigger() to soc_pcm_trigger().

Hi All,
Here are 2 simple fixes which are necessary to make the
cht_bsw_nau8824 machine driver work together with the
sof-audio-acpi driver.
Note that atm the sof topology files are missing a .tplg
file for this setup. Simply copying over the standard
sof-byte-codec.tplg file does the trick, but then some
mixer setting changes are necessary to fix the right
speaker/headphones channel not working; and those mixer
settings break the right channel when used with the
sst-acpi driver.
I've been trying to fix this at the tplg level so that
we do not need to change the mixer settings, but no luck
sofar. I'll post a RFC with the topology changes which
I have and we can discuss this further there.
These 2 simple fixes are necessary to make the sof-audio-acpi
driver work regardless of the topology issue.
Regards,
Hans
cz_da7219_init() does not check the return values of clk_get(),
while da7219_clk_enable() calls clk_set_rate() to dereference
the pointers.
Add checks to fix the problems.
Also, change clk_get() to devm_clk_get() to avoid data leak after
failures.

The cx2072x codec driver defines multiple DAIs with the same stream
name "Playback" and "Capture". Although the current code works more
or less as is as the secondary streams are never used, it still leads
the error message like:
debugfs: File 'Playback' in directory 'dapm' already present!
debugfs: File 'Capture' in directory 'dapm' already present!
Fix it by renaming the secondary streams to unique names.

The snd-soc-sst-acpi driver does not care about the id specified for
the SSP2-Codec DAI, but it does matter for the snd-sof-acpi driver;
and when it is not 0 then the snd-sof-acpi driver does not work.
Set the SSP2-Codec DAI id to 0, fixing the snd-sof-acpi driver not
working on devices using the cht_bsw_nau8824 machine-driver.

When using the snd-soc-sst-acpi driver then the compress-cpu-dai bits are
not used, the cht_bsw_nau8824 machine-driver is the only BYT/CHT driver
defining them.
When using the snd-sof-acpi driver then the presence of the
compress-cpu-dai bits breaks things because the sof topology file for
by/cht devices does not contain routing info for them.
Drop the compress-cpu-dai bits, fixing the snd-sof-acpi driver not

The "filter" debugfs file defines the log levels used by
the firmware and reported by sof-logger.
The file contains the formatted entry list, where each entry
follows the following syntax in plain text:
log_level uuid_id pipe_id comp_id;
This file may be updated by userspace applications such sof-logger,
or directly by the user during debugging process.
An unused (wildcard) pipe_id or comp_id value should be set to -1,
uuid_id is hexadecimal value, so when unused then should be set to 0.
When the file is modified, an IPC command is sent to FW with new
trace levels for selected components in filter elements list.

A recent change removed the call to send the DAPM_STREAM_STOP
event in dpcm_fe_dai_shutdown. But this causes a regression
when a PCM prepare is not paired with a hw_free. So, add
the DAPM_STREAM_STOP event back to dpcm_fe_dai_shutdown()
to fix this.
The new sequence would be:
soc_pcm_prepare()
-> SND_SOC_DAPM_STREAM_START
soc_pcm_hw_free()
-> soc_pcm_hw_free()
-> SND_SOC_DAPM_STREAM_STOP
dpcm_fe_dai_shutdown()
-> SND_SOC_DAPM_STREAM_STOP
Note that the DAPM_STREAM_STOP will be called twice but it seems
harmless.

The series supports new machines with rt1015p and rt5682. Reuses most of
the code in mt8192-mt6359-rt1015-rt5682.c.
The first 3 patches refactor the existing mt8192-mt6359-rt1015-rt5682.c.
For easier to support newly added components later.
The 4th patch fixes a typo in DT bindings document.
The 5th patch proposes a new compatible string "mt8192_mt6359_rt1015p_rt5682"
for machines with rt1015p and rt5682.
The 6th patch reuses the existing machine driver to support machines with
rt1015p and rt5682.
