21cfbeae7d ASoC: rockchip: i2s_tdm: Re-add the set_sysclk callback
[ Upstream commit 5323186e2e ]

In commit
9e2ab4b18e ("ASoC: rockchip: i2s-tdm: Fix inaccurate sampling rates"),
the set_sysclk callback was removed as considered unused as the mclk rate
can be set in the hw_params callback.
The difference between hw_params and set_sysclk is that the former is
called with the audio sampling rate set in the params (e.g.: 48000 Hz)
while the latter is called with a clock rate already computed with
  sampling_rate * mclk-fs (e.g.: 48000 * 256)

For HDMI audio using the Rockchip I2S TDM driver, the mclk-fs value must
be set to 128 instead of the default 256, and that value is set in the
device tree at the machine driver level (like a simple-audio-card
compatible node).
Therefore, the i2s_tdm driver has no idea that another mclk-fs value can
be configured and simply computes the mclk rate in the hw_params callback
with DEFAULT_MCLK_FS * params_rate(params), which is wrong for HDMI
audio.

Re-add the set_sysclk callback so that the mclk rate is computed by the
machine driver which has the correct mclk-fs value set in its device tree
node.

8f6c2ed42e ALSA: hda: Fix compilation of snd_hdac_adsp_xxx() helpers
[ Upstream commit 7579790915 ]

The snd_hdac_adsp_xxx() wrap snd_hdac_reg_xxx() helpers to simplify
register access for AudioDSP drivers e.g.: the avs-driver. Byte- and
word-variants of said helps do not expand to bare readx/writex()
operations but functions instead and, due to pointer type
incompatibility, cause compilation to fail.

As the macros are utilized by the avs-driver alone, relocate the code
introduced with commit c19bd02e90 ("ALSA: hda: Add helper macros for
DSP capable devices") into the avs/ directory and update it to operate
on 'adev' i.e.: the avs-driver-context directly to fix the issue.

7db7597f7b ASoC: mediatek: disable buffer pre-allocation
[ Upstream commit 32c9c06adb ]

On Chromebooks based on Mediatek MT8195 or MT8188, the audio frontend
(AFE) is limited to accessing a very small window (1 MiB) of memory,
which is described as a reserved memory region in the device tree.

On these two platforms, the maximum buffer size is given as 512 KiB.
The MediaTek common code uses the same value for preallocations. This
means that only the first two PCM substreams get preallocations, and
then the whole space is exhausted, barring any other substreams from
working. Since the substreams used are not always the first two, this
means audio won't work correctly.

This is observed on the MT8188 Geralt Chromebooks, on which the
"mediatek,dai-link" property was dropped when it was upstreamed. That
property causes the driver to only register the PCM substreams listed
in the property, and in the order given.

Instead of trying to compute an optimal value and figuring out which
streams are used, simply disable preallocation. The PCM buffers are
managed by the core and are allocated and released on the fly. There
should be no impact to any of the other MediaTek platforms.

909ecf15cb ASoC: SOF: Intel: hda-dai: Do not release the link DMA on STOP
commit e8d0ba147d upstream.

The linkDMA should not be released on stop trigger since a stream re-start
might happen without closing of the stream. This leaves a short time for
other streams to 'steal' the linkDMA since it has been released.

This issue is not easy to reproduce under normal conditions as usually
after stop the stream is closed, or the same stream is restarted, but if
another stream got in between the stop and start, like this:
aplay -Dhw:0,3 -c2 -r48000 -fS32_LE /dev/zero -d 120
CTRL+z
aplay -Dhw:0,0 -c2 -r48000 -fS32_LE /dev/zero -d 120

then the link DMA channels will be mixed up, resulting firmware error or
crash.

e385c781a3 firmware: arm_scmi: Fix i.MX build dependency
[ Upstream commit 514b2262ad ]

The newly added SCMI vendor driver references functions in the
protocol driver but needs a Kconfig dependency to ensure it can link,
essentially the Kconfig dependency needs to be reversed to match the
link time dependency:

  |  arm-linux-gnueabi-ld: sound/soc/fsl/fsl_mqs.o: in function `fsl_mqs_sm_write':
  |  	fsl_mqs.c:(.text+0x1aa): undefined reference to `scmi_imx_misc_ctrl_set'
  |  arm-linux-gnueabi-ld: sound/soc/fsl/fsl_mqs.o: in function `fsl_mqs_sm_read':
  |  	fsl_mqs.c:(.text+0x1ee): undefined reference to `scmi_imx_misc_ctrl_get'

This however only works after changing the dependency in the SND_SOC_FSL_MQS
driver as well, which uses 'select IMX_SCMI_MISC_DRV' to turn on a
driver it depends on. This is generally a bad idea, so the best solution
is to change that into a dependency.

To allow the ASoC driver to keep building with the SCMI support, this
needs to be an optional dependency that enforces the link-time
dependency if IMX_SCMI_MISC_DRV is a loadable module but not
depend on it if that is disabled.

e4ac72dd79 ASoC: tas2781: Fix calibration issue in stress test
[ Upstream commit 2aa13da97e ]

One specific test condition: the default registers of p[j].reg ~
p[j+3].reg are 0, TASDEVICE_REG(0x00, 0x14, 0x38)(PLT_FLAG_REG),
TASDEVICE_REG(0x00, 0x14, 0x40)(SINEGAIN_REG), and
TASDEVICE_REG(0x00, 0x14, 0x44)(SINEGAIN2_REG). After first calibration,
they are freshed to TASDEVICE_REG(0x00, 0x1a, 0x20), TASDEVICE_REG(0x00,
0x16, 0x58)(PLT_FLAG_REG), TASDEVICE_REG(0x00, 0x14, 0x44)(SINEGAIN_REG),
and TASDEVICE_REG(0x00, 0x16, 0x64)(SINEGAIN2_REG) via "Calibration Start"
kcontrol. In second calibration, the p[j].reg ~ p[j+3].reg have already
become tas2781_cali_start_reg. However, p[j+2].reg, TASDEVICE_REG(0x00,
0x14, 0x44)(SINEGAIN_REG), will be freshed to TASDEVICE_REG(0x00, 0x16,
0x64), which is the third register in the input params of the kcontrol.
This is why only first calibration can work, the second-time, third-time
or more-time calibration always failed without reboot. Of course, if no
p[j].reg is in the list of tas2781_cali_start_reg, this stress test can
work well.

036d4d0d11 ASoC: SOF: ipc3-topology: fix resource leaks in sof_ipc3_widget_setup_comp_dai()
[ Upstream commit 6d544ea21d ]

These error paths should free comp_dai before returning.

eee02810ce ASoC: SOF: ipc3-topology: Convert the topology pin index to ALH dai index
[ Upstream commit e9db1b5517 ]

Intel SoundWire machine driver always uses Pin number 2 and above.
Currently, the pin number is used as the FW DAI index directly. As a
result, FW DAI 0 and 1 are never used. That worked fine because we use
up to 2 DAIs in a SDW link. Convert the topology pin index to ALH dai
index, the mapping is using 2-off indexing, iow, pin #2 is ALH dai #0.

The issue exists since beginning. And the Fixes tag is the first commit
that this commit can be applied.

b09a655dc7 ASoC: da7213: Populate max_register to regmap_config
commit 9d4f9f6a7b upstream.

On the Renesas RZ/G3S SMARC Carrier II board having a DA7212 codec (using
da7213 driver) connected to one SSIF-2 available on the Renesas RZ/G3S SoC
it has been discovered that using the runtime PM API for suspend/resume
(as will be proposed in the following commits) leads to the codec not
being propertly initialized after resume. This is because w/o
max_register populated to regmap_config the regcache_rbtree_sync()
breaks on base_reg > max condition and the regcache_sync_block() call is
skipped.

b5bcf578e8 ASoC: codecs: Fix atomicity violation in snd_soc_component_get_drvdata()
commit 1157733344 upstream.

An atomicity violation occurs when the validity of the variables
da7219->clk_src and da7219->mclk_rate is being assessed. Since the entire
assessment is not protected by a lock, the da7219 variable might still be
in flux during the assessment, rendering this check invalid.

To fix this issue, we recommend adding a lock before the block
if ((da7219->clk_src == clk_id) && (da7219->mclk_rate == freq)) so that
the legitimacy check for da7219->clk_src and da7219->mclk_rate is
protected by the lock, ensuring the validity of the check.

This possible bug is found by an experimental static analysis tool
developed by our team. This tool analyzes the locking APIs
to extract function pairs that can be concurrently executed, and then
analyzes the instructions in the paired functions to identify possible
concurrency bugs including data races and atomicity violations.
