ASoC: soc-dai: add snd_soc_pcm_dai_bespoke_trigger()
We have 2 type of component functions
snd_soc_dai_xxx()     is focusing to dai itself,
snd_soc_pcm_dai_xxx() is focusing to rtd related dai.

Now we can update soc_pcm_bespoke_trigger() to
snd_soc_pcm_dai_bespoke_trigger(). This patch do it.

Merge series "Add support for SOF on i.MX8M" from Daniel Baluta <daniel.baluta@oss.nxp.com>
Daniel Baluta <daniel.baluta@nxp.com>:

From: Daniel Baluta <daniel.baluta@nxp.com>

This patch series adds support for SOF on i.MX8M family. First board
from this family that has a DSP is i.MX8MP.

First 2 patches are trying to fix some compilation issues, the next two
are adding the imx8m support and the last one adds the devicetree
binding.

Changes since v2:
 - add reviewed by from Rob to DT patch
 - fix ownership for patch 2

Daniel Baluta (3):
  ASoC: SOF: imx: Add i.MX8M HW support
  ASoC: SOF: Add i.MX8MP device descriptor
  dt-bindings: dsp: fsl: Add fsl,imx8mp-dsp entry

Pierre-Louis Bossart (1):
  ASoC: SOF: imx: fix undefined reference issue

Stephan Gerhold 9b5db05936
ASoC: soc-pcm: dpcm: Only allow playback/capture if supported
At the moment, PCM devices for DPCM are only created based on the
dpcm_playback/capture parameters of the DAI link, without considering
if the CPU/FE DAI is actually capable of playback/capture.

Normally the dpcm_playback/capture parameter should match the
capabilities of the CPU DAI. However, there is no way to set that
parameter from the device tree (e.g. with simple-audio-card or
qcom sound cards). dpcm_playback/capture are always both set to 1.

This causes problems when the CPU DAI does only support playback
or capture. Attemting to open that PCM device with an unsupported
stream type then results in a null pointer dereference:

    Unable to handle kernel NULL pointer dereference at virtual address 0000000000000128
    Internal error: Oops: 96000044 [#1] PREEMPT SMP
    CPU: 3 PID: 1582 Comm: arecord Not tainted 5.7.0-rc1
    pc : invalidate_paths_ep+0x30/0xe0
    lr : snd_soc_dapm_dai_get_connected_widgets+0x170/0x1a8

     snd_pcm_capture_open+0x4c/0x78
     snd_open+0xac/0x1a8
     ...

... because the DAI playback/capture_widget is not set in that case.

We could add checks there to fix the problem (maybe we should
anyway), but much easier is to not expose the device as
playback/capture in the first place. Attemting to use that
device would always fail later anyway.

Add checks for snd_soc_dai_stream_valid() to the DPCM case
to avoid exposing playback/capture if it is not supported.

ASoC: dpcm: allow start or stop during pause for backend
soc_compr_trigger_fe() allows start or stop after pause_push.
In dpcm_be_dai_trigger(), however, only pause_release is allowed
command after pause_push.
So, start or stop after pause in compress offload is always
returned as error if the compress offload is used with dpcm.
To fix the problem, SND_SOC_DPCM_STATE_PAUSED should be allowed
for start or stop command.

ASoC: export DPCM runtime update functions
This makes DPCM runtime update functions available for external
calling. As an example, virtualised ASoC component drivers may need
to call these when managing shared DAPM routes that are used by more
than one driver (i.e. when host driver and guest drivers have a DAPM
path from guest PCM to host DAI where some parts are owned by host
driver and others by guest driver).

ASoC: (cosmetic) simplify dpcm_prune_paths()
Currently dpcm_prune_paths() has up to 4 nested condition and loop
levels, which forces the code to use flags for flow control.
Extracting widget status verification code from dpcm_prune_paths()
into a separate function simplifies the code.

soc_pcm_hw_free() want to call snd_soc_dai_digital_mute()
if it was last user of Playback or Capture.

	bool playback = substream->stream == SNDRV_PCM_STREAM_PLAYBACK;
	int playback_active = dai->stream_active[SNDRV_PCM_STREAM_PLAYBACK];
	int capture_active  = dai->stream_active[SNDRV_PCM_STREAM_CAPTURE];

	if ((playback  && playback_active == 1) ||
	    (!playback && capture_active  == 1))

But it is same as

	int active = dai->stream_active[substream->stream];

	if (active == 1)
		snd_soc_dai_digital_mute(...)

ASoC: soc-pcm: fix state tracking error in snd_soc_component_open/close()
ASoC component open/close and snd_soc_component_module_get/put are called
independently for each component-substream pair, so the logic added in
commit dd03907bf1 ("ASoC: soc-pcm: call snd_soc_component_open/close()
once") was not sufficient and led to PCM playback and module unload errors.

Implement handling of failures directly in soc_pcm_components_open(),
so that any successfully opened components are closed upon error with
other components. This allows to clean up error handling in
soc_pcm_open() without adding more state tracking.

ASoC: soc-pcm: move dpcm_path_put() to soc-pcm.c
dpcm_path_put() (A) is calling kfree(*list).
The freed list is created by dapm_widget_list_create() (B) which is called
from snd_soc_dapm_dai_get_connected_widgets() (C) which is called from
dpcm_path_get() (D).

(B)	dapm_widget_list_create(**list, ...)
	{
		...
=>		*list = kzalloc();
		...
	}

(C)	snd_soc_dapm_dai_get_connected_widgets(..., **list, ...)
	{
		...
		dapm_widget_list_create(list, ...);
		...
	}

(D)	dpcm_path_get(..., **list)
	{
		...
		snd_soc_dapm_dai_get_connected_widgets(..., list, ...);
		...
	}

(A)	dpcm_path_put(**list)
	{
=>		kfree(*list);
	}

This kind of unbalance code is very difficult to read/understand.
To avoid this issue, this patch adds each missing paired function
dapm_widget_list_free()         for dapm_widget_list_create() (B), and
snd_soc_dapm_dai_free_widgets() for snd_soc_dapm_dai_get_connected_widgets() (C).

This patch uses these, and moves dpcm_path_put() next to dpcm_path_get().

ASoC: pcm: Fix possible buffer overflow in dpcm state sysfs output
dpcm_show_state() invokes multiple snprintf() calls to concatenate
formatted strings on the fixed size buffer.  The usage of snprintf()
is supposed for avoiding the buffer overflow, but it doesn't work as
expected because snprintf() doesn't return the actual output size but
the size to be written.

Fix this bug by replacing all snprintf() calls with scnprintf()
calls.

ASoC: soc-pcm: fix regression in soc_new_pcm()
Commit af4bac1153 ("ASoC: soc-pcm: crash in snd_soc_dapm_new_dai")
swapped the SNDRV_PCM_STREAM_* parameter in the
snd_soc_dai_stream_valid(cpu_dai, ...) checks. But that works only
for codec2codec links. For normal links it breaks registration of
playback/capture-only PCM devices.

E.g. on qcom/apq8016_sbc there is usually one playback-only and one
capture-only PCM device, but they disappeared after the commit.

The codec2codec case was added in commit a342031cdd
("ASoC: create pcm for codec2codec links as well") as an extra check
(e.g. `playback = playback && cpu_playback->channels_min`).

We should be able to simplify the code by checking directly for
the correct stream type in the loop.
This also fixes the regression because we check for PLAYBACK for
both codec and cpu dai again when codec2codec is not used.

soc_pcm_open() operation order is not good.
At first, soc_pcm_open() operation order is

	1) CPU DAI startup
	2) Component open
	3) Codec DAI startup
	4) rtd startup

But here, 2) will call try_module_get() if component has
module_get_upon_open flags. This means 1) CPU DAI startup
will be operated *before* its module was loaded.
DAI should be called *after* Component.

Second, soc_pcm_close() operation order is
	1) CPU DAI shutdown
	2) Codec DAI shutdown
	3) rtd shutdown
	4) Component close

soc_pcm_open() and soc_pcm_close() are paired function,
but, its operation order is unbalance.
