ASoC: soc-component: Update handling to component delays
Currently the checking for if a component sits on the CPU or CODEC side
of the DAI link is done with a helper function that checks if the
component defines legacy_dai_naming. However, there are already a couple
of CPU side components that explicitly opt in to non-legacy DAI naming
and it doesn't seem like a very robust solution. Rather than looking for
the flag check if the component is attached to any of the CODEC DAIs on
the DAI link. This is more robust and helps to bring the core further in
the direction of a component being a generic block rather than being
classified as platform or CODEC drivers.

ASoC: soc-component: add snd_soc_pcm_component_delay()
Current soc-pcm.c :: soc_pcm_pointer() is assuming that
component driver might update runtime->delay silently in
snd_soc_pcm_component_pointer() (= A).

	static snd_pcm_uframes_t soc_pcm_pointer(...)
	{
		...

		/* clearing the previous total delay */
=>		runtime->delay = 0;

(A)		offset = snd_soc_pcm_component_pointer(substream);

		/* base delay if assigned in pointer callback */
=>		delay = runtime->delay;
		...
	}

1) The behavior that ".pointer callback secretly updates
   runtime->delay" is strange and confusable.

2) Current snd_soc_pcm_component_pointer() uses 1st found component's
   .pointer callback only, thus it is no problem for now.
   But runtime->delay might be overwrote if it adjusted to multiple
   components in the future.

3) Component delay is updated at .pointer callback timing (secretly).
   But some components which doesn't have .pointer callback might want
   to increase runtime->delay for some reasons.

We already have .delay function for DAI, but not have for Component.
This patch adds new snd_soc_pcm_component_delay() for it.

ASoC: soc-component: improve error reporting for register access
Currently errors on register read/write/update are reported with
an error code and the corresponding function but does not provide
any details on the which register number did it actually fail.

register number can give better clue and it should be easy to
locate the code and fix.

ASoC: compress/component: Use module_get_when_open/put_when_close for cstream
Currently the try_module_get() and module_put() is not possible for
compressed streams if the module_get_upon_open is set to 1 which means that\
the components are not protected in a same way as components when normal
audio is used.

SOF is setting module_get_upon_open to 1 for component drivers which works
correctly for audio stream but when compressed stream is used then the
module is not protected.

Convert the compress open and free operation to mimic the steps of it's
pcm counterpart to fix this issue.

ASoC: soc-component: Convert the mark_module to void*
The mark_module of the snd_soc_component is strict snd_pcm_substream type
which prevents it to be used by compressed streams.

Change the type to void* along with the snd_soc_component_module_get()
and snd_soc_component_module_put() to allow the same mark to be used by
compressed when it's module_get_upon_open is set to 1.

ASoC: component: Remove misplaced prefix handling in pin control functions
When the component level pin control functions were added they for some
no longer obvious reason handled adding prefixing of widget names. This
meant that when the lack of prefix handling in the DAPM level pin
operations was fixed by ae4fc53224 (ASoC: dapm: use component
prefix when checking widget names) the one device using the component
level API ended up with the prefix being applied twice, causing all
lookups to fail.

Fix this by removing the redundant prefixing from the component code,
which has the nice side effect of also making that code much simpler.

ASoC: soc-component: add snd_soc_component_read/write_field()
It's often the case that we would write or read a particular field
in register. With the current soc_component apis, reading a particular
field in register would involve first read the register and then
perform shift operations.

Ex:
to read from a field mask of 0xf0

	val = snd_soc_component_read(component, reg);
	field = ((val & 0xf0) >> 0x4);

This is sometimes prone to errors and code become less readable!

With this new api we could just do
	field = snd_soc_component_read_field(component, reg, 0xf0);

this makes it bit simple, easy to write and less error prone!

This also applies to writing!

There are various places in kernel which provides such field interfaces
however soc_component seems to be missing this.

This patch is inspired by FIELD_GET/FIELD_PREP macros in include/linux/bitfield.h

ASoC: soc-pcm: care trigger rollback
soc_pcm_trigger() calls DAI/Component/Link trigger,
but some of them might be failed.

	static int soc_pcm_trigger(...)
	{
		...
		switch (cmd) {
		case SNDRV_PCM_TRIGGER_START:
		case SNDRV_PCM_TRIGGER_RESUME:
		case SNDRV_PCM_TRIGGER_PAUSE_RELEASE:
			ret = snd_soc_link_trigger(substream, cmd);
			if (ret < 0)
				break;

(*)			ret = snd_soc_pcm_component_trigger(substream, cmd);
			if (ret < 0)
				break;

			ret = snd_soc_pcm_dai_trigger(substream, cmd);
			break;
		case SNDRV_PCM_TRIGGER_STOP:
		case SNDRV_PCM_TRIGGER_SUSPEND:
		case SNDRV_PCM_TRIGGER_PAUSE_PUSH:
			ret = snd_soc_pcm_dai_trigger(substream, cmd);
			if (ret < 0)
				break;

			ret = snd_soc_pcm_component_trigger(substream, cmd);
			if (ret < 0)
				break;

			ret = snd_soc_link_trigger(substream, cmd);
			break;
		}
		...
	}

For example, if soc_pcm_trigger() failed at (*) point,
we need to rollback previous succeeded trigger.

This patch adds trigger mark for DAI/Component/Link,
and do STOP if START/RESUME/PAUSE_RELEASE were failed.

Because it need to use new rollback parameter,
we need to modify DAI/Component/Link trigger functions in the same time.

ASoC: soc-component: add mark for snd_soc_component_compr_open/free()
soc_compr_open() does rollback when failed (A),
but, it is almost same as soc_compr_free().

	static int soc_compr_open(xxx)
	{
		...

			goto xxx_err;
		...
		return 0;

 ^	machine_err:
 |		...
 |	out:
(A)		...
 |	pm_err:
 |		...
 v		return ret;
	}

The difference is
soc_compr_free()  is for all dai/component/substream,
rollback          is for succeeded part only.

This kind of duplicated code can be a hotbed of bugs,
thus, we want to share soc_compr_free() and rollback.
	1) snd_soc_dai_compr_startup/shutdown()
=>	2) snd_soc_component_compr_open/free()
	3) snd_soc_link_compr_startup/shutdown()

This patch is for 2) snd_soc_component_compr_open/free(),
and adds new cstream mark.
It will mark cstream when startup() was suceeded.
If rollback happen *after* that, it will check rollback flag
and marked cstream.

It cares *previous* startup() only now,
but we might want to check *whole* marked cstream in the future.
This patch is using macro so that it can be easily adjust to it.

This patch is for 2) snd_soc_pcm_component_hw_params/free().

The idea of having bit-flag or counter is not enough for this purpose.
For example if one DAI is used for 2xPlaybacks for some reasons,
and if 1st Playback was succeeded but 2nd Playback was failed,
2nd Playback rollback doesn't need to call shutdown.
But it has succeeded bit-flag or counter via 1st Playback,
thus, 2nd Playback rollback will call unneeded shutdown.
And 1st Playback's necessary shutdown will not be called,
because bit-flag or counter was cleared by wrong 2nd Playback rollback.

To avoid such case, this patch marks substream pointer when hw_params() was
succeeded. If rollback needed, it will check rollback flag and marked
substream pointer.

One note here is that it cares *previous* hw_params() only now,
but we might want to check *whole* marked substream in the future.
This patch is using macro named "push/pop", so that it can be easily
update.

To avoid such case, this patch marks substream pointer when get() was
succeeded. If rollback needed, it will check rollback flag and marked
substream pointer.

One note here is that it cares *current* get() only now.
but we might want to check *whole* marked substream in the future.
This patch is using macro named "push/pop", so that it can be easily
update.

ASoC: soc-component: add mark for soc_pcm_components_open/close()
soc_pcm_open() does rollback when failed (A),
but, it is almost same as soc_pcm_close().

	static int soc_pcm_open(xxx)
	{
		...
		if (ret < 0)
			goto xxx_err;
		...
		return 0;

 ^	config_err:
 |		...
 |	rtd_startup_err:
(A)		...
 |	component_err:
 |		...
 v		return ret;
	}

The difference is
soc_pcm_close() is for all dai/component/substream,
rollback        is for succeeded part only.

This kind of duplicated code can be a hotbed of bugs,
thus, we want to share soc_pcm_close() and rollback.

Now, soc_pcm_open/close() are handling
	1) snd_soc_dai_startup/shutdown()
	2) snd_soc_link_startup/shutdown()
=>	3) snd_soc_component_module_get/put()
=>	4) snd_soc_component_open/close()
	5) pm_runtime_put/get()

This patch is for 3) snd_soc_component_module_get/put()
4) snd_soc_component_open/close().

The idea of having bit-flag or counter is not enough for this purpose.
For example if one DAI is used for 2xPlaybacks for some reasons,
and if 1st Playback was succeeded but 2nd Playback was failed,
2nd Playback rollback doesn't need to call shutdown.
But it has succeeded bit-flag or counter via 1st Playback,
thus, 2nd Playback rollback will call unneeded shutdown.
And 1st Playback's necessary shutdown will not be called,
because bit-flag or counter was cleared by wrong 2nd Playback rollback.

To avoid such case, this patch marks substream pointer when open() was
succeeded. If rollback needed, it will check rollback flag and marked
substream pointer.

One note here is that it cares *current* open() only now.
but we might want to check *whole* marked substream in the future.
This patch is using macro named "push/pop", so that it can be easily
update.

ASoC: Make soc_component_read() returning an error code again
Along with the recent unification of snd_soc_component_read*()
functions, the behavior of snd_soc_component_read() was changed
slightly; namely it returns the register read value directly, and even
if an error happens, it returns zero (but it prints an error
message).  That said, the caller side can't know whether it's an error
or not any longer.

Ideally this shouldn't matter much, but in practice this seems causing
a regression, as John reported.  And, grepping the tree revealed that
there are still plenty of callers that do check the error code, so
we'll need to deal with them in anyway.

As a quick band-aid over the regression, this patch changes the return
value of snd_soc_component_read() again to the negative error code.
It can't work, obviously, for 32bit register values, but it should be
enough for the known regressions, so far.

With commit e2329eeba4 ("ASoC: soc-component: add soc_component_err()")
every error different for ENOTSUPP or EPROBE_DEFER will log an error.

However, as explained in snd_soc_get_dai_name(), this callback may error
to indicate that the DAI is not matched by the component tested. If the
device provides other components, those may still match. Logging an error
in this case is misleading.

Don't use soc_component_ret() in snd_soc_component_of_xlate_dai_name()
to avoid spamming the log.

ASoC: soc-component: use io_mutex correctly

ASoC: soc-component: merge snd_soc_component_read() and snd_soc_component_read32()
We had read/write function for Codec, Platform, etc,
but these has been merged into snd_soc_component_read/write().

Internally, it is using regmap or driver function.
In read case, each styles are like below

regmap
	ret = regmap_read(..., reg, &val);

driver function
	val = xxx->read(..., reg);

Because of this kind of different style, to keep same read style,
when we merged each read function into snd_soc_component_read(),
we created snd_soc_component_read32(), like below.
commit 738b49efe6 ("ASoC: add snd_soc_component_read32")

(1)	val = snd_soc_component_read32(component, reg);

(2)	ret = snd_soc_component_read(component, reg, &val);

Many drivers are using snd_soc_component_read32(), and
some drivers are using snd_soc_component_read() today.

In generally, we don't check read function successes,
because, we will have many other issues at initial timing
if read function didn't work.

Now we can use soc_component_err() when error case.
This means, it is easy to notice if error occurred.

This patch aggressively merge snd_soc_component_read() and _read32(),
and makes snd_soc_component_read/write() as generally style.

This patch do
	1) merge snd_soc_component_read() and snd_soc_component_read32()
	2) it uses soc_component_err() when error case (easy to notice)
	3) keeps read32 for now by #define
	4) update snd_soc_component_read() for all drivers

Because _read() user drivers are not too many, this patch changes
all user drivers.

ASoC: soc-core: remove snd_soc_rtdcom_list
Current ALSA SoC is using struct snd_soc_rtdcom_list to
connecting component to rtd by using list_head.

	struct snd_soc_rtdcom_list {
		struct snd_soc_component *component;
		struct list_head list; /* rtd::component_list */
	};

	struct snd_soc_pcm_runtime {
		...
		struct list_head component_list; /* list of connected components */
		...
	};

The CPU/Codec/Platform component which will be connected to rtd (a)
is indicated via dai_link at snd_soc_add_pcm_runtime()

	int snd_soc_add_pcm_runtime(...)
	{
		...
		/* Find CPU from registered CPUs */
		rtd->cpu_dai = snd_soc_find_dai(dai_link->cpus);
		...
(a)		snd_soc_rtdcom_add(rtd, rtd->cpu_dai->component);
		...

		/* Find CODEC from registered CODECs */
(b)		for_each_link_codecs(dai_link, i, codec) {
			rtd->codec_dais[i] = snd_soc_find_dai(codec);
			...
(a)			snd_soc_rtdcom_add(rtd, rtd->codec_dais[i]->component);
		}
		...

		/* Find PLATFORM from registered PLATFORMs */
(b)		for_each_link_platforms(dai_link, i, platform) {
			for_each_component(component) {
				...
(a)				snd_soc_rtdcom_add(rtd, component);
			}
		}

	}

It shows, it is possible to know how many components will be
connected to rtd by using

	dai_link->num_cpus
	dai_link->num_codecs
	dai_link->num_platforms

If so, we can use component pointer array instead of list_head,
in such case, code can be more simple.
This patch removes struct snd_soc_rtdcom_list that is only
of temporary value, and convert to pointer array.
