Break the clock setting logic out from the main hw_params.  It's
rather large and unweildy and makes for a large function.  This
also better enables some of the following changes to the clock

ASoC: wm_adsp: Add HALO MPU fault logging
A Halo Core DSP has a memory protection unit that can trap and signal
memory access faults. This patch adds a function that dumps the fault
information.

The interrupt reaches the host via the parent codec interrupt controller
so this fault function is exported to be called by the codec driver.

ASoC: mediatek: Reduce repititive code on mtk_regmap_update_bits.
Change the signature of mtk_regmap_update_bits to also take a shift, and

ASoC: mediatek: Fix UBSAN warning.
In sound/soc/mediatek/common/mtk-afe-fe-dai.c, when xxx_reg is -1, it's
a no-op to call mtk_regmap_update_bits, but since both xxx_reg and
xxx_shift are set to -1, the (1 << xxx_shift) in the argument would
trigger a UBSAN warning.

Fix the warning by setting those xxx_shift to 0 instead.

Note that since the code explicitly checks .mono_shift >= 0 and
.fs_shift >= 0 before using them in '<<' operator, those two members are
not set to 0.

ASoC: wm_adsp: Move wm_adsp2_set_dspclk to CODEC drivers
The original wm_adsp2_early_event took an additional frequency
argument for clocking control so could not be used directly as a
DAPM callback. But this setup could equally be done by the codec
driver function wrapping wm_adsp2_early event. In preparation
for adding support for new core types wm_adsp2_set_dspclk has
been exported, and the freq argument removed so that it can
be used directly as a DAPM callback.

ASoC: wm_adsp: Correct handling of compressed streams that restart
Previously support was added to allow streams to be stopped and
started again without the DSP being power cycled and this was done
by clearing the buffer state in trigger start. Another supported
use-case is using the DSP for a trigger event then opening the
compressed stream later to receive the audio, unfortunately clearing
the buffer state in trigger start destroys the data received
from such a trigger. Correct this issue by moving the call to
wm_adsp_buffer_clear to be in trigger stop instead.

ASoC: rt5651: Add support for active-high jack detect
Some boards use a jack-receptacle with a switch which reports the

reporting most jacks use.

This commit adds support for it. This is activated by a boolean
"realtek,jack-detect-not-inverted" device-property. The not-inverted
in the device-property name, rather then active-high, was chosen to keep
the device-property naming consistent with the rt5640 codec driver.

ASoC: samsung: odroid: Fix clock configuration for 44100 sample rate
After commit fbeec965b8d1c ("ASoC: samsung: odroid: Fix 32000 sample rate
handling") the audio root clock frequency is configured improperly for
44100 sample rate. Due to clock rate rounding it's 20070401 Hz instead
of 22579000 Hz. This results in a too low value of the PSR clock divider
in the CPU DAI driver and too fast actual sample rate for fs=44100. E.g.
1 kHz tone has actual 1780 Hz frequency (1 kHz * 20070401/22579000 * 2).

Fix this by increasing the correction passed to clk_set_rate() to take
into account inaccuracy of the EPLL frequency properly.

If playback and capture are enabled concurrently, when the capture stops

ASoC:hdac_hda:use correct format to setup hda codec
The current implementation of the hdac_hda codec results in zero-valued
samples on capture and noise with headset playback when SOF is used on
platforms with an on-board HDaudio codec. This is root-caused to SOF
using be_hw_params_fixup, and the prepare() call using invalid runtime
fields to determine the format.

This patch moves the format handling to the hw_params() callback, as
done already for hdac_hdmi, to make sure the fixed-up information is
taken into account but keeps the codec initialization in prepare() as
the stream_tag is only available at that time. Moving everything in the
prepare() callback is possible but the code is less elegant so this
two-step solution was chosen.

The solution was tested with the SST driver with no regressions, and all
the issues with SOF playback and capture are solved.

ASoC:soc-pcm:fix a codec fixup issue in TDM case
On HDaudio platforms, if playback is started when capture is working,
there is no audible output.

This can be root-caused to the use of the rx|tx_mask to store an HDaudio
stream tag.

If capture is stared before playback, rx_mask would be non-zero on HDaudio
platform, then the channel number of playback, which is in the same codec
dai with the capture, would be changed by soc_pcm_codec_params_fixup based
on the tx_mask at first, then overwritten by this function based on rx_mask
at last.

According to the author of tx|rx_mask, tx_mask is for playback and rx_mask
is for capture. And stream direction is checked at all other references of
tx|rx_mask in ASoC, so here should be an error. This patch checks stream
direction for tx|rx_mask for fixup function.

This issue would affect not only HDaudio+ASoC, but also I2S codecs if the
channel number based on rx_mask is not equal to the one for tx_mask. It could
be rarely reproduecd because most drivers in kernel set the same channel number
to tx|rx_mask or rx_mask is zero.

Tested on all platforms using stream_tag & HDaudio and intel I2S platforms.

ASoC: ti: fix davinci_mcasp_probe dependencies
The SND_SOC_DAVINCI_MCASP driver can use either edma or sdma as
a back-end, and it takes the presence of the respective dma engine
drivers in the configuration as an indication to which ones should be
built. However, this is flawed in multiple ways:

- With CONFIG_TI_EDMA=m and CONFIG_SND_SOC_DAVINCI_MCASP=y,
  is enabled as =m, and we get a link error:
  sound/soc/ti/davinci-mcasp.o: In function `davinci_mcasp_probe':
  davinci-mcasp.c:(.text+0x930): undefined reference to `edma_pcm_platform_register'

- When CONFIG_SND_SOC_DAVINCI_MCASP=m has already been selected by
  another driver, the same link error appears even if CONFIG_TI_EDMA
  is disabled

There are possibly other issues here, but it seems that the only reasonable
solution is to always build both SND_SOC_TI_EDMA_PCM and
SND_SOC_TI_SDMA_PCM as a dependency here. Both are fairly small and
do not have any other compile-time dependencies, so the cost is
very small, and makes the configuration stage much more consistent.

one error path where if any of the prelinks for a soundcard failed to
initialise, then these platform pointers would not be cleaned-up. This
then prevents the soundcard from being initialised following a probe
deferral when any of the soundcard prelinks cannot be found.

Fix this by ensuring that soc_cleanup_platform() is called when
initialising the soundcard prelinks fails.

ASoC: hdmi-codec: avoid limiting params->msbits in hw_params()
Limiting the value of the passed in params->msbits in the hw_params()
callback is redundant on three counts:

1. We already specify in the DAI driver that we can only handle up to
   24 bits.  This means msbits will be limited to 24 via the ALSA
   constraints imposed by the ASoC core, unless we have multiple codecs
   that can handle more bits.

2. Nothing in our hw_params() implementation uses this value.

3. The copy of the params that we are passed by the ASoC core never
   reads back the msbits value.

Consequently, this code is unnecessary and does nothing useful.  Remove
it.

ASoC: hdmi-codec: fix S/PDIF DAI
When using the S/PDIF DAI, there is no requirement to call
snd_soc_dai_set_fmt() as there is no DAI format definition that defines
S/PDIF.  In any case, S/PDIF does not have separate clocks, this is
embedded into the data stream.

Consequently, when attempting to use TDA998x in S/PDIF mode, the attempt
to configure TDA998x via the hw_params callback fails as the
hdmi_codec_daifmt is left initialised to zero.

Since the S/PDIF DAI will only be used by S/PDIF, prepare the
hdmi_codec_daifmt structure for this format.

ASoC: tlv320aic3x: fix reset gpio reference counting
This patch fixes a bug that prevents freeing the reset gpio on unloading
the module.

aic3x_i2c_probe is called when loading the module and it calls list_add
with a probably uninitialized list entry aic3x->list (next = prev = NULL)).
So even if list_del is called it does nothing and in the end the gpio_reset
is not freed. Then a repeated module probing fails silently because
gpio_request fails.

When moving INIT_LIST_HEAD to aic3x_i2c_probe we also have to move
list_del to aic3x_i2c_remove because aic3x_remove may be called
multiple times without aic3x_i2c_remove being called which leads to
a NULL pointer dereference.

ASoC: qcom: Fix of-node refcount unbalance in qcom_snd_parse_of()
Although qcom_snd_parse_of() tries to manage the of-node refcount,
there are still a few places that lead to the unblanced refcount in
the error code path.  Namely,

- for_each_child_of_node() needs to unreference the iterator node if
  aborting the loop in the middle,
- cpu, codec and platform node objects have to be unreferenced at each
  iteration,
- platform and codec node objects have to be referred before jumping
  to the error handling code that unreference them unconditionally.

This patch tries to address these by moving the assignment of platform
and codec node objects to the beginning of the loop and adding the
of_node_put() calls adequately.

codec that aborts the loop as well.  Last but not least, the inner

the refcount of the iterator node.

from the primary device name. The secondary device name will now
be <primary_dev_name>-sec instead of fixed "samsung-i2s-sec".

The fixed platform_device_id table entry is removed as the secondary
device name is now dynamic and device/driver matching is done through

ASoC: Intel: Add Geminilake Dialog Maxim machine driver
This patch enables support for GeminiLake with the DA7219 codec and
MAX98357A amplifier. To avoid duplicating code, the existing machine
driver for ApolloLake is reused with only changes in hardware
connectivity (SSP2 for DA7219 and SSP1 for MAX98357A).

The dailinks are directly modified in this patch. Using a helper would
be nicer, but it'll be done in a follow-up step with validation done
across multiple machine drivers.

Currently when playing sound with different sample rates actual
sample rate will be determined by audio stream which starts first
on either primary or secondary PCM. The audio root clock will be
configured appropriately only for the first stream. As the hardware
is limited to same sample rate on both interfaces we need to disallow
streams with different sample rates. It is done by this patch by
returning error in FE hw_params if there is already active stream
running with different sample rate.

ASoC: da7219: Update TDM usage to be more flexible
The previous implementatation was restrictive with regards to
BCLK rates for slave mode where the driver would not allow rates
the codec couldn't provide itself as clock master. The codec
is able to automatically determine and handle whatever rate is
provided so this restriction isn't necessary for slave mode. The
code was also flawed with regards to setting of the frame offset
as using rx_mask to explicitly set the offset has the knock on
effect of impacting the min and max channels for the codec, in
soc_pcm_hw_params() through the call to
soc_pcm_codec_params_fixup().

With this update, the driver now only limits frame size if codec
is clock master, and dynamically determines the BCLK offset
relating to WCLK using the tx_mask for slot offset along with the
slot width provided.

ASoC: samsung: i2s: Get rid of a static spinlock
This patch makes the spinlock serializing access to the primary/secondary
PCM a per I2S controller lock, rather than a global one. There is no need
to have a global lock across multiple I2S controllers in the SoC.

ASoC: samsung: i2s: Drop spinlock pointer from i2s_dai data structure
As we now have the 'priv' pointer in most of the places we can use
priv->lock directly, dropping extra indirection in the SFR region
spinlock access.
