This reverts commit f6a0dd107a.
The commit caused a regression on LINE6 Transport that has no control
caps. Although reverting the commit may result back in a spurious
error message for some device again, it's the simplest regression fix,
hence it's taken as is at first. The further code fix will follow
later.

This adds the respective Kconfig dependencies and changes SND_SOC_ES8328 to a hidden
symbol that is selected implicitly by the two more specific options, as we do for
some other codecs. We have to remove the 'depends on' for SND_SOC_IMX_ES8328 in the
same step to avoid a recursive dependency.

snd_seq_pool_done() syncs with closing of all opened threads, but it
aborts the wait loop with a timeout, and proceeds to the release
resource even if not all threads have been closed. The timeout was 5
seconds, and if you run a crazy stuff, it can exceed easily, and may
result in the access of the invalid memory address -- this is what
syzkaller detected in a bug report.
As a fix, let the code graduate from naiveness, simply remove the loop

This is again a big rewrite of the driver; now it touches the code to
process PCM stream transfers.
The most fundamental change is that the driver may support more than
four periods. Instead of keeping the same index between both the ring
buffer (with the fixed four buffer descriptors) and the PCM buffer
periods, we keep difference indices for both (bd_head and pcm_head
fields). In addition, when the periods are more than four, we need to
track both head and next indices. That is, we now have three indices:
bd_head, pcm_head and pcm_filled.
Also, the driver works better for periods < 4, too: the remaining BDs
out of four are marked as invalid, so that the hardware skips those
BDs in its loop.
By this flexibility, we can use even ALSA-lib dmix plugin, which
requires 16 periods as default.
The buffer size could be up to 20bit, so the max buffer size was
increased accordingly. However, the buffer pre-allocation is kept as
the old value (600kB) as default. The reason is the limited number of
BDs: since it doesn't suffice for the useful SG page management that
can fit with the usual page allocator like some other drivers, we have
to still allocate continuous pages, hence we shouldn't take too big
memories there.

This is the final stage for a big clean-up series. Here we flatten
the two layers into one. Formerly, the implementation was split to
HDMI "shell" that talks with the platform device, and HDMI audio part
that communicates via caps and other event handlers. All these would
be good if there were multiple instantiations or if there were data
protection. But neither are true in our case. That said, it'll be
easier to have a flat driver structure in the end.
In this patch, the former struct hdmi_lpe_audio_ctx is forged into the
existing struct snd_intelhad. The latter has already a few members
that are basically the copy from the former. Only a few new members
for the lowlevel I/O are added by this change.
Then, the had_get_caps() and had_set_caps() are simply replaced with
the direct calls to copy the data in the struct fields. Also, the
had_event_handler() calls are replaced with the direct call for each
event as well.

For reducing the global variable reference, keep snd_intelhad object

for further cleanup.
This also includes the simplification of the probe procedure: the LPE
platform driver directly gets the created snd_intelhad object by
hdmi_audio_probe(), and passes it to each helper and destructor,
hdmi_audio_remove(). The hdmi_audio_probe() function doesn't call the
back-registration any longer, which is fairly useless. The LPE

On Baytrail and Cherrytrail, HDaudio may be fused out or disabled

display registers and DMA.
Although there is no hardware path between i915 display and LPE/SST
audio clusters, this HDMI capability is referred to in the documentation
as "HDMI LPE Audio" so we keep the name for consistency. There is no
hardware path or control dependencies with the LPE/SST DSP functionality.
The hdmi-lpe-audio driver will be probed when the i915 driver creates
a child platform device.
Since this driver is neither SoC nor PCI, a new x86 folder is added

In system resume, the firmware pipelines will be created again and the

The SAIF base oversample rates are either 512*fs or 384*fs. An additional
divider exists within the SAIF to generate sub-multiples of these two base
rates if MCLK is required by the codec.
* The sub-rates for the 512x base rate are: 256x, 128x, 64x, and 32x.
* The sub-rates for the 384x base rate are: 192x, 96x, and 48x.
Setting the base rate depending on the modulo operation with 32 and 48
give wrong results for some mclk.
If mclk=18.432MHz both modulo operations results in 0. As testing the
result with 32 is done first, a wrong base rate of 512*fs is set instead
of the correct 384*fs.
Fix this by setting the base rate depending on the calculated sub-rate.

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.
