[ Upstream commit 37e1df8c95e2c8a57c77eafc097648f6e40a60ff ]
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.

[ Upstream commit 02c5c03283c52157d336abf5e44ffcda10579fbf ]
The i2s clock pre-divider 1 is used for both i2s1 and sysclk.
The i2s1 is usually used for the main i2s and the pre-divider
will be set in hw_params function.
However, if i2s2 is used, the pre-divider is not set in the hw_params
function and the default value of i2s clock pre-divider 1 is too high
for sysclk and DMIC usage. Fix by overriding default divider value to 2.

connected frontend dailinks are closed.

[ Upstream commit 4ee437fbf626b5ad756889d8bc0fcead3d66dde7 ]
The fsl_ssi fifo watermark is by default set to 2 free spaces (i.e.
activate DMA on FIFO when only 2 spaces are left.) This means the
DMA must service the fifo within 2 audio samples, which is just not
enough time for many use cases with high data rate. In many
configurations the audio channel slips (causing l/r swap in stereo
configurations, or channel slipping in multi-channel configurations).
This patch gives more breathing room and allows the SSI to operate
reliably by changing the fifio refill watermark to 8.
There is no change in behavior for older chips (with an 8-deep fifo).
Only the newer chips with a 15-deep fifo get the new behavior. I
suspect a new fifo depth setting could be optimized on the older
chips too, but I have not tested.

commit fe0dfd6358a17c79bd7d6996af7512ba452a7059 upstream.
Thinkpad Helix 2 is a tablet PC, the audio is powered by Core M
broadwell-audio and rt286 codec. For all versions of Linux kernel,
the stereo output doesn't work properly when earphones are plugged
in, the sound was coming out from both channels even if the audio
contains only the left or right channel. Furthermore, if a music
recorded in stereo is played, the two channels cancle out each other
out, as a result, no voice but only distorted background music can be
heard, like a sound card with builtin a Karaoke sount effect.
Apparently this tablet uses a combo jack with polarity incorrectly
set by rt286 driver. This patch adds DMI information of Thinkpad Helix 2
to force_combo_jack_table[] and the issue is resolved. The microphone
input doesn't work regardless to the presence of this patch and still
needs help from other developers to investigate.
This is my first patch to LKML directly, sorry for CC-ing too many
people here.

commit 4efda5f2130da033aeedc5b3205569893b910de2 upstream.
soc_cleanup_card_resources() call snd_card_free() at the last of its
procedure. This turned out to lead to a use-after-free.
PCM runtimes have been already removed via soc_remove_pcm_runtimes(),
while it's dereferenced later in soc_pcm_free() called via
snd_card_free().
The fix is simple: just move the snd_card_free() call to the beginning
of the whole procedure. This also gives another benefit: it
guarantees that all operations have been shut down before actually
releasing the resources, which was racy until now.

commit 6e4cac23c5a648d50b107d1b53e9c4e1120c7943 upstream.
The FE setups of Intel SST bytcr_rt5640 and bytcr_rt5651 drivers carry
the ignore_suspend flag, and this prevents the suspend/resume working
properly while the stream is running, since SST core code has the
check of the running streams and returns -EBUSY. Drop these
superfluous flags for fixing the behavior.
Also, the bytcr_rt5640 driver lacks of nonatomic flag in some FE
definitions, which leads to the kernel Oops at suspend/resume like:

pointer
commit d1a6fe41d3c4ff0d26f0b186d774493555ca5282 upstream.
In 'skl_tplg_set_module_init_data()', a pointer to 'params' member of
'struct skl_algo_data' is calculated, then casted to (u32 *) and assigned
to a member of configuration data. The configuration data is passed to the
other functions and used to process intel IPC. In this processing, the
value of member is used to get message data, however this can bring invalid
memory access in 'skl_set_module_params()' as a result of calculation of
a pointer for actual message data.

commit 5faf071d08ddd1c1be66deaa93a09ccf43f5b538 upstream.
Unfortunately, I seem to have missed a case where an IRQ safe spinlock was
required, in samsung_i2s_dai_remove, when I fixed up the other calls in
this patch:
316fa9e09ad7 ("ASoC: samsung: Use IRQ safe spin lock calls")
This causes a lockdep warning when unbinding and rebinding the audio card:

commit 3b89e4b77ef9c2f985964fab17032db98f074ed0 upstream.
A bugfix accidentally removed the implicit initialization of the
dma channel number, causing undefined behavior when
v->alloc_dma_channel is NULL:
sound/soc/qcom/lpass-platform.c: In function ‘lpass_platform_pcmops_open’:
sound/soc/qcom/lpass-platform.c:83:29: error: ‘dma_ch’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
This adds back an explicit initialization to zero, restoring the
previous behavior for that case.

In commit 022d00ee0b55 ("ASoC: lpass-platform: Fix broken pcm data
usage") the stream specific information initialization was broken, with
the dma channel information not being initialized if there was no
alloc_dma_channel() helper function.
Before that, the DMA channel number was implicitly initialized to zero
because the backing store was allocated with devm_kzalloc(). When the
init code was rewritten, that implicit initialization was lost, and gcc
rightfully complains about an uninitialized variable being used.

In the current probe function the GPIO is acquired after the codec's
bus clock is enabled. However if it fails to acquire the GPIO due to
a deferred probe, it does not disable the bus clock before bailing out.
This would result in the clock being enabled multiple times.
Move the code that enables the bus clock after the part that gets the
GPIO, maintaining a separation between resource acquisition and device
enablement in the probe function.

This patch fixes lpass-platform driver which was broken in v4.9-rc1.
lpass_pcm_data data structure holds information specific to stream.
Holding a single private pointer to it in global lpass_data
will not work, because it would be overwritten by for each pcm instance.
This code was breaking playback when we have both playback and capture
pcm streams, as playback settings are over written by capture settings.
Fix this by moving channel allocation logic out of pcm_new to pcm_open
so that we can store the stream specific information in private_data of
snd_pcm_runtime.

When sun4i_codec_create_card fails, we do not assign a proper error
code to the return value. The return value would be 0 from the previous
function call, or we would have bailed out sooner. This would confuse
the driver core into thinking the device probe succeeded, when in fact
it didn't, leaving various devres based resources lingering.
Make the create_card function pass back a meaningful error code, and
assign it to the return value.

If a DAI specifies "#sound-dai-cells = <0>" in device-tree then
hdmi_of_xlate_dai_name() will be called with zero args, which it isn't
implemented to cope with. The resulting use of an uninitialised variable
for the id will usually result in an error like:
asoc-simple-card sound: parse error -11
asoc-simple-card: probe of sound failed with error -11
Fix this by using and id of zero if no arg is provided.

ASoC Samsung sub-drivers tried to get access to their DMA engine
controllers as a last step in driver probe. If a DMA engine was not
available yet, samsung_asoc_dma_platform_register() function ended in
-EPROBE_DEFER, but the driver already registered its component to ASoC
core. This patch moves samsung_asoc_dma_platform_register() call before
registering any components, to the common place, where driver was gathering
all needed resources.
In case of Samsung Exynos i2s driver the issue was even worse. The driver
managed already to register its secondary DAI platform device before
even getting the DMA engine access. That together with -EPROBE_DEFER error
code from samsung_i2s_probe() immediately triggered another round of
deferred probe retry and in turn endless loop of driver probing.
This patch fixes broken boot on Odroid XU3 and other Exynos5422-based
boards.

HDMI codec is required to be powered up before controller initialization
for successful enumeration of codec. If the probe fails it needs to be
powered off to balance the power state of HDMI codec.
This fix balances the reference count in the error path before turning
off the codec.
