When we open one capture stream on one instance lets say I2S_SP and then

first capture is in progress and when we try to read the status of both
running instances by below command cat /proc/asound/card2/pcm?c/sub0/status
we observe that avail_max is being doubled on first opened
capture(I2S_SP in the example).
This is because our previous implementation was like when any instance is
opened it gets initialized in dma_open irrespective of on what instance it
called open.
For example:
First I2S_SP called opened it initializes both SP/BT capture streams
irrespective of on which instance the stream opened.next time I2S_BT
called opened and it initializes both SP/BT this corrupts the behaviour .
So with this patch the stream gets initialized only on specific instance

ASoC: qcom: lpass-cpu: Make I2S SD lines configurable
The LPASS hardware allows configuring the MI2S SD lines to use
when playing/recording audio. However, at the moment the lpass-cpu
driver has SD0 hard-coded for mono/stereo (or additional fixed
SD lines for more channels).
For weird reasons there seems to be hardware that uses one of the
other SD lines for mono/stereo. For example, some Samsung devices
use an external Speaker amplifier connected to Quaternary MI2S.
For some reason, the SD line for audio playback was connected to
SD1 rather than SD0. (I have no idea why...)
At the moment, the lpass-cpu driver cannot be configured to work
for the Speaker on these devices.
The q6afe driver already allows configuring the MI2S SD lines
through the "qcom,sd-lines" device tree property, but this works
only when routing audio through the ADSP.
This commit adds a very similar configuration for the lpass-cpu driver.
It is now possible to add additional subnodes to the lpass device in
the device tree, to configure the SD lines for playback and/or capture.
E.g. for the Samsung devices mentioned above:
qcom,playback/capture-sd-lines takes a list of SD lines (0-3)
in the same format as the q6afe driver. (The difference here is that
q6afe has separate DAIs for playback/capture, while lpass-cpu has one
for both...)
For backwards compatibility with older device trees, the lpass-cpu driver
defaults to LPAIF_I2SCTL_MODE_8CH if the subnode for a DAI is missing.
This is equivalent to the previous behavior: Up to 8 channels can be
configured, and SD0/QUAT01 will be chosen when setting up a stream
with fewer channels.
This allows the speaker to work on Samsung MSM8916 devices
that use an external speaker amplifier.
When calling regmap_update_bits(), since map->reg_update_bits is NULL,
_regmap_read() is entered with the following logic:
if (!map->cache_bypass) {
ret = regcache_read(map, reg, val);
if (ret == 0)
return 0;
}
if (map->cache_only)
return -EBUSY;
regcache_read() hits -EINVAL because MAX98373_R2000_SW_RESET is volatile,
as map->cache_only is set by codec suspend, thus -EBUSY is returned.
Fix by moving max98373_reset() after cache_only set to false in max98373_resume().

ASoC: SOF: Intel: change trigger sequence to fix pop noise when

This is complicated by two drivers having dependencies on both
platform specific drivers and the SND_SOC_SOF_OF framework code,
and using an somewhat obscure method to build them the same way
as the SOC_SOF_OF symbol (built-in or modular).
My solution now ensures that the two drivers can only be enabled
when the dependencies are met:
- When the platform specific drivers are built-in, everything is
fine, as SOC_SOF_OF is either =y or =m
- When both are loadable modules, it also works, both for Kconfig
and at runtime
- When the hardware drivers are loadable modules or disabled, and
SOC_SOF_OF=y, prevent the IMX_SOF_OF drivers from being turned on,
as this would be broken.
It seems that this is just an elaborate way to describe two tristate
symbols that have straight dependencies, but maybe I'm missing some
subtle point. It seems to always build for me now.
ASoC: SOF: Intel: change trigger sequence to fix pop noise when stopping playback on sdw platforms
Now the trigger sequence is set to SND_SOC_DPCM_TRIGGER_POST for
SOF. This means FE will be stopped before BE, so BE will consume
invalid data and this generates huge pop noise. This sequence is
introduced for HDA DAI which requires SND_SOC_DPCM_TRIGGER_POST for
some reasons. Now set default trigger sequence to SND_SOC_DPCM_TRIGGER_PRE
for playback with all DAI and fix sequence only for HDA DAI.
ASoC: SOF: topology: replace sof_link_hda_process by sof_set_dai_config
Now we send ipc in sof_set_dai_config(), too. Therefore, we can use
