Some drivers use one event callback for multiple widgets but still need
to perform a bit different actions based on actual widget. This is done
by comparing widget name, however drivers tend to miss possible name
prefix. Add a helper to solve common mistakes.

While transitioning ASoC code for iov_iter usages, I kept the argument
name as "buf" as the original code. But, iov_iter is an iterator, and
using the name "buf" may be misleading: the crucial difference is that
iov_iter can be proceeded after the operation, hence it can't be
passed twice, while a simple "buffer" sounds as if reusable.
To make the usage clearer, rename the argument from "buf" to "iter".
There is no functional changes, just names.

For following the ALSA PCM core change, a new PCM copy ops is added
toe ASoC component framework: snd_soc_component_driver receives the
copy ops, and snd_soc_pcm_component_copy() helper is provided.
This also fixes a long-standing potential bug where the ASoC driver
covers only copy_user PCM callback and misses the copy from kernel
pointers (such as OSS PCM layer), too.
As of this patch, the old copy_user is still kept, but it'll be
dropped later after all drivers are converted.

soc-pcm.c has snd_soc_dpcm_mutex_lock/unlock(),

This is due to the fact that the pm_runtime_resume_and_get() is calling
pm_runtime_put_noidle() in case of < 0 return value of
pm_runtime_get_sync() which includes the -EACCES.
The change is wrong as -EACCES is returned in case of 'nested' get_sync()

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.

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.

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.

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

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.

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.

Current soc-xxx are getting rtd from substream by
rtd = substream->private_data;
But, getting data from "private_data" is very unclear.
This patch adds asoc_substream_to_rtd() macro which is
easy to understand that rtd from substream.

component has io_mutex, but it had been used at
snd_soc_component_update_bits_legacy() only which does read and write.
static int snd_soc_component_update_bits_legacy(...)
{
...
=> mutex_lock(&component->io_mutex);
...
old = snd_soc_component_read(...);
...
ret = snd_soc_component_write(...);
...
=> mutex_unlock(&component->io_mutex);
...
}
It is pointless if it is not used with both read and write functions.
This patch uses io_mutex correctly with read/write.
Here, xxx_no_lock() is local functions.
static int snd_soc_component_read(...)
{
...
=> mutex_lock(&component->io_mutex);
val = soc_component_read_no_lock(...);
=> mutex_unlock(&component->io_mutex);

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.
