55cdf93234 ASoC: pcm: Update RX shutdown sequence
Update RX shutdown sequence so that codec
path gets tear down first followed by cpu dai.
This will avoid slim port underflow/overflows
when slim data protocol is changed.

84e6857d3d ASoC: pcm: Add support for fixup callback
Fixup callback is added for dais which
do not follow the FE and BE convention
and is directly controlled by userspace
such as hostless dais. This will restrict
the hw_params based on what is supported by
hardware rather than blindly setting what
is given by userspace.

Backend DAI.

110ad9d27a ASoC: Cold start latency reduction
This patch parallelizes FE (front end) and BE (back end)
when playback/capture path is set up. FE's and BE's which can
be parallelized should be indicated in corresponding machine file.
All the operations can be started asynchronously provided the usecase
supports asynchronous operation.
Parallelizing reduces the startup latency as both FE and BE operations
run in parallel.

The pcm delay_blk() op collects the audio DSP path
delays from the low-level drivers and sets the
runtime->delay field to their aggregate.

will help to set pcm start event for all the codec dais

all the codec_dais capture_active bit to set start stream

f1031ca0f7 ASoC: pcm: increase the hostless buffer size
PAGE_SIZE buffer is not enough in all use cases.This
limits the amount of buffer that can be passed from
userspace. Not increasing this causes failure in pcm_native

the hw_params based on what is supported by

commit 5e82d2be6ee53275c72e964507518d7964c82753 upstream.

While performing hw_free, DPCM checks the BE state but leaves out
the suspend state. The suspend state needs to be checked as well,
as we might be suspended and then usermode closes rather than
resuming the audio stream.

This was found by a stress testing of system with playback in
loop and killed after few seconds running in background and second
script running suspend-resume test in loop

1ce43acff0 ASoC: dapm: Simplify list creation in dapm_dai_get_connected_widgets()
When running dapm_dai_get_connected_widgets() currently in
is_connected_{input,output}_ep() for each widget that gets added the array
is resized and the code also loops over all existing entries to avoid
adding a widget multiple times.

The former can be avoided by collecting the widgets in a linked list and
only once we have all widgets allocate the array.

The later can be avoided by changing when the widget is added. Currently it
is added when walking the neighbor lists of a widget. Since a widget can be
neighbors with multiple other widgets it could get added twice and hence
the check is necessary. But the main body of is_connected_{input,output}_ep
is guaranteed to be only executed at most once per widget. So adding the
widget to the list at the beginning of the function automatically makes
sure that each widget gets only added once. The only difference is that
using this method the starting point itself will also end up on the list,
but it can easily be skipped when creating the array.

Overall this reduces the code size and speeds things slightly up.

c5b8540dca ASoC: dpcm: Add checks of playback/capture before dpcm_get_be
In dpcm_get_be(), it looks for a BE rtd that has the DAI widget
according to current stream type. Only playback_widgets are searched
in the case of playback stream and vice versa. However, the DAI widget
itself can be playback or capture.

If the DAI widget is capture, but current stream type is playback,
dpcm_get_be() will always fail to find a rtd, print error messages,
and continue to the next DAI widget in list. We can just skip this
DAI widget to further suppress error messages. This happens in a
special case when 2 codecs are inter-connected, and the 1st codec's
"capture" widget is used to send data to the 2nd codec during "playback":

mtk-rt5650-rt5676 sound: ASoC: can't get playback BE for Sub AIF2 Capture
rt5650_rt5676 Playback: ASoC: no BE found for Sub AIF2 Capture

Add checks to continue to next DAI widget if current DAI widget's
direction does not match the stream type.

if FE/BE was below style, and user selects S24_LE format.

This patch adds new .dpcm_merged_format on struct snd_soc_dai_link.
DPCM will use FE / BE merged format if .struct snd_soc_dai_link

36fba62cce ASoC: soc-pcm: do not hw_free BE if it's still used
Do not free BE hw if it's still used by other FE during dpcm runtime
shutdown. Otherwise the BE runtime state will be STATE_HW_FREE and
won't be updated to STATE_CLOSE when shutdown ends, because BE dai
shutdown function won't close pcm when detecting BE is still under
use. With STATE_HW_FREE, BE can't be triggered start again.

This corner case can easily appear when one BE is used by two FE,
without this patch "ASoC: dpcm: Fix race between FE/BE updates and
trigger"(ea9d0d771f). One FE tries to
shutdown but it's raced against xrun on another FE. It improves the
be dai hw_free logic.

ea9d0d771f ASoC: dpcm: Fix race between FE/BE updates and trigger
DPCM can update the FE/BE connection states totally asynchronously
from the FE's PCM state.  Most of FE/BE state changes are protected by
mutex, so that they won't race, but there are still some actions that
are uncovered.  For example, suppose to switch a BE while a FE's
stream is running.  This would call soc_dpcm_runtime_update(), which
sets FE's runtime_update flag, then sets up and starts BEs, and clears
FE's runtime_update flag again.

When a device emits XRUN during this operation, the PCM core triggers
snd_pcm_stop(XRUN).  Since the trigger action is an atomic ops, this
isn't blocked by the mutex, thus it kicks off DPCM's trigger action.
It eventually updates and clears FE's runtime_update flag while
soc_dpcm_runtime_update() is running concurrently, and it results in
confusion.

Usually, for avoiding such a race, we take a lock.  There is a PCM
stream lock for that purpose.  However, as already mentioned, the
trigger action is atomic, and we can't take the lock for the whole
soc_dpcm_runtime_update() or other operations that include the lengthy
jobs like hw_params or prepare.

This patch provides an alternative solution.  This adds a way to defer
the conflicting trigger callback to be executed at the end of FE/BE
state changes.  For doing it, two things are introduced:

- Each runtime_update state change of FEs is protected via PCM stream
  lock.
- The FE's trigger callback checks the runtime_update flag.  If it's
  not set, the trigger action is executed there.  If set, mark the
  pending trigger action and returns immediately.
- At the exit of runtime_update state change, it checks whether the
  pending trigger is present.  If yes, it executes the trigger action
  at this point.
