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.

The existing soc-dapm code may add a prefix to control names, which in
some cases is useful but in others leads to long and confusing kcontrol
names such as "gain 2.1 Main Playback Volume".
This patch suggests an added flag to prevent the widget name prefix
from being added. That flag will be set in the topology file on a
per-widget basis.
The flag no_wname_in_kcontrol_name is added to struct snd_soc_dapm_widget,
and the logic in dapm_create_or_share_kcontrol() is changed to not to
add widget name if the flag is set.

Currently, ASoC supports dailinks with the following mappings:
1 cpu DAI to N codec DAIs
N cpu DAIs to N codec DAIs
But the mapping between N cpu DAIs and M codec DAIs is not supported.
The reason is that we didn't have a mechanism to map cpu and codec DAIs
This patch suggests a new snd_soc_dai_link_codec_ch_map struct in
struct snd_soc_dai_link{} which provides codec DAI to cpu DAI mapping
information used to implement N cpu DAIs to M codec DAIs
support.
When a dailink contains two or more cpu DAIs, we should set channel
number of cpus based on its channel mask. The new struct also provides
channel mask information for each codec and we can construct the cpu
channel mask by combining all codec channel masks which map to the cpu.
The N:M mapping is however restricted to the N <= M case due to physical
restrictions on a time-multiplexed bus such as I2S/TDM, AC97, SoundWire
and HDaudio.

When a widget is added to dapm via snd_soc_dapm_new_widgets,
dapm_debugfs_add_widget is also called to create a corresponding debugfs
file. However, when a widget is freed by snd_soc_dapm_free_widget, the
corresponding debugfs is not cleared. As a result, the freed widget is
still seen in the dapm directory.
This patch adds dapm_debugfs_free_widget to free the debugfs of a
specified widget, and it's called at snd_soc_dapm_free_widget to clean
up the debugfs for freed widget.

soc.h has snd_soc_dapm_mutex_lock/unlock() definition and
many drivers are using it, but soc-dapm.c is not.
1st reason is snd_soc_dapm_mutex_lock/unlock() requests
snd_soc_dapm_context pointer as parameter (A), but sometimes soc-dapm.c
needs to use snd_soc_card (B).
(A) static inline void snd_soc_dapm_mutex_lock(struct snd_soc_dapm_context *dapm)
{
mutex_lock_nested(&dapm->card->dapm_mutex, SND_SOC_DAPM_CLASS_RUNTIME);
} ^^^^^^^^^^
(B) mutex_lock_nested(&card->dapm_mutex, SND_SOC_DAPM_CLASS_RUNTIME);
^^^^
2nd reason is it want to use SND_SOC_DAPM_CLASS_INIT for mutex_lock_nested(),
but helper is using _RUNTIME (A).
The conclusion is we want to use "dapm vs card" and "_RUNTIME vs _INIT"
for dapm lock/unlock. To enable this selfish request, this patch uses
_Generic macro. We can use snd_soc_dapm_mutex_lock/unlock() for both
dapm and card case.
snd_soc_dapm_mutex_lock(dapm); snd_soc_dapm_mutex_unlock(dapm);
snd_soc_dapm_mutex_lock(card); snd_soc_dapm_mutex_unlock(card);
Current soc-dapm.c is using both mutex_lock() and mutex_lock_nested().
This patch handles mutex_lock() as mutex_lock_nested(..., 0),
in other words, handles below as same.
mutex_lock(&card->dapm_mutex);
mutex_lock_nested(&card->dapm_mutex, SND_SOC_DAPM_CLASS_INIT);
Because people might misunderstand that _init() is mutex initialization,
this patch renames _INIT to _ROOT and adds new
snd_soc_dapm_mutex_lock_root() for it.
This patch also moves snd_soc_dapm_subclass definition from soc-dapm.h
to soc.h to keep related code together.
Because very complex soc.h vs soc-dapm.h relationship,
it is difficult/impossible to define these helper into soc-dapm.h.

dapm_connect_dai_pair() handles
"Normal/Codec2Codec" x "CPU/Codec" x "Playback/Capture".
(A) is "Codec2Codec" case of "CPU" widget x "Playback/Capture",
(B) is "Normal" case of "CPU" widget x "Playback/Capture",
(C) is each case of "Codec" widget.
(X) is handling "Playback" case DAI connecting,
(Y) is handling "Capture" case DAI connecting.
static void dapm_connect_dai_pair(...)
{
...
(A) if (dai_link->params) {
playback_cpu = ...
capture_cpu = ...
(B) } else {
playback_cpu = ...
capture_cpu = ...
}
^ /* connect BE DAI playback if widgets are valid */
| stream = SNDRV_PCM_STREAM_PLAYBACK;
| (C) codec = codec_dai->playback_widget;
|
| if (playback_cpu && codec) {
(X) if (dai_link->params && !rtd->c2c_widget[stream]) {
| ...
| }
|
| (z) dapm_connect_dai_routes(...);
v }
capture:
^ /* connect BE DAI capture if widgets are valid */
| stream = SNDRV_PCM_STREAM_CAPTURE;
| (C) codec = codec_dai->capture_widget;
|
| if (codec && capture_cpu) {
(Y) if (dai_link->params && !rtd->c2c_widget[stream]) {
| ...
| }
|
| (z) dapm_connect_dai_routes(...);
v }
}
(X) part and (Y) part are almost same.
Main purpose of these parts (and this function) is calling
dapm_connect_dai_routes() (= z) on each cases.
The difference is "parameter"
(= Normal/Codec2Codec x CPU/Codec x Playback/Capture).
This patch cleanup these, but nothing changed for meaning.

Currently we sequence speakers with line and headphone outputs in DAPM.
This works well when speakers are integrate into a CODEC but when there is
an external speaker driver connected to a line or headphone output it can
mean that the speaker driver ends up getting sequenced such that it picks
up pops and clicks from the CODEC. Mask this by moving speakers after the
other outputs in DAPM.
We may want to consider doing this for headphones too but separate drivers
are less common there and headphone drivers often also function as line
outputs so the situation is less clear.

Current snd_soc_dapm_new_control_unlocked() error handling is wrong.
It is using "goto request_failed" (A), but error message is using
"w->name" (B) which is not yet created in such timing.
snd_soc_dapm_new_control_unlocked(xxx)
{
...
switch (w->id) {
case xxx:
...
if (IS_ERR(...)) {
ret = PTR_ERR(...);
(A) goto request_failed;
}
...
}
prefix = soc_dapm_prefix(...);
if (prefix)
(B) w->name = kasprintf(...);
else
(B) w->name = kstrdup_const(...);
...
(A) request_failed:
if (ret != -EPROBE_DEFER)
(B) dev_err(..., w->name, ...);
return ...;
}
we can create "w->name" at beginning of this function.
In such case, we need to call kfree_const(w->name) at error case.
This patch do these.

Current snd_soc_dai_link_event_pre_pmu() is checking "config".
It is using dev_err() (A) if it was NULL, so we don't need to use
WARN_ON() (B) to check it, it is over-kill. This patch removes it.
(B) if (WARN_ON(!config)) {
(A) dev_err(...);
...
}

For sysfs outputs, it's safer to use a new helper, sysfs_emit(),
instead of the raw sprintf() & co. This patch replaces the open-code
with a new helper, sysfs_emit_at(), by passing the string offset.

Further development will need some of the fixes.

DAPM keeps a copy of the current value of mux/demux controls,
however this value is only initialised in the case of autodisable
controls. This leads to false notification events when first
modifying a DAPM kcontrol that has a non-zero default.
Autodisable controls are left as they are, since they already
initialise the value, and there would be more work required to
support autodisable muxes where the first option isn't disabled
and/or that isn't the default.
Technically this issue could affect mixer/switch elements as well,
although not on any of the devices I am currently running. There
is also a little more work to do to address the issue there due to
that side supporting stereo controls, so that has not been tackled
in this patch.

Tidy up the code a little, rather than repeating the check of
mc->autodisable move the stereo error check to be under the
existing if for mc->autodisable.

DAPM tracks and reports the value presented to the user from DAPM controls
separately to the register value, these may diverge during initialisation
or when an autodisable control is in use.
When writing DAPM controls we currently report that a change has occurred
if either the DAPM value or the value stored in the register has changed,
meaning that if the two are out of sync we may appear to report a spurious
event to userspace. Since we use this folded in value for nothing other
than the value reported to userspace simply drop the folding in of the
register change.

These two bug are here:
list_for_each_entry_safe_continue(w, n, list,
power_list);
list_for_each_entry_safe_continue(w, n, list,
power_list);
After the list_for_each_entry_safe_continue() exits, the list iterator
will always be a bogus pointer which point to an invalid struct objdect
containing HEAD member. The funciton poniter 'w->event' will be a
invalid value which can lead to a control-flow hijack if the 'w' can be
controlled.
The original intention was to continue the outer list_for_each_entry_safe()
loop with the same entry if w->event is NULL, but misunderstanding the
meaning of list_for_each_entry_safe_continue().
So just add a 'continue;' to fix the bug.

To allow for more flexibility i.e. populating component DAIs dynamically
during its initialization, without being limited to topology loading
procedure, expose snd_soc_register(), snd_soc_dapm_new_dai_widgets() and
snd_soc_dapm_free_widget() functions.
Allows users to first check available resources e.g. number of PCMs
supported by HDAudio codec before allocating the number of DAPM
widgets needed. This prevents superfluous objects from being created or
allows driver to adjust to situation when resources are limited.

The recent fix for DAPM to correct the kctl change notification by the
commit 5af82c81b2c4 ("ASoC: DAPM: Fix missing kctl change
notifications") caused other regressions since it changed the behavior
of snd_soc_dapm_set_pin() that is called from several API functions.
Formerly it returned always 0 for success, but now it returns 0 or 1.
This patch addresses it, restoring the old behavior of
snd_soc_dapm_set_pin() while keeping the fix in
snd_soc_dapm_put_pin_switch().

The put callback of a kcontrol is supposed to return 1 when the value
is changed, and this will be notified to user-space. However, some
DAPM kcontrols always return 0 (except for errors), hence the
user-space misses the update of a control value.
This patch corrects the behavior by properly returning 1 when the
value gets updated.
