Lars-Peter Clausen 02f51640fe ASoC: wm1133-ev1: Use card DAPM context to access widgets
The dapm field of the snd_soc_codec struct will eventually be removed
(replaced with the DAPM context from the component embedded inside the
CODEC). Replace its usage with the card's DAPM context. The idea is that
DAPM is hierarchical and with the card at the root it is possible to access
widgets from other contexts through the card context.

Lars-Peter Clausen 7ca92b8f5a ASoC: atmel: Add dependency to SND_SOC_I2C_AND_SPI where necessary
The SND_AT91_SOC_SAM9G20_WM8731 and SND_AT91_SOC_SAM9X5_WM8731 machine
driver symbols select SND_SOC_WM8731 which depends on SND_SOC_I2C_AND_SPI.
So the machine driver symbols need to depend on SND_SOC_I2C_AND_SPI as well,
otherwise we might end up with a invalid configuration, which will sooner or
later upset the randconfig auto-builders.

Al Viro 1c65d98672 pcm: another weird API abuse
readv() and writev() should _not_ ignore all but the first ->iov_len,
among other things.  Really weird abuse of those syscalls - it
expects a vector element per channel, with identical lengths (it
actually assumes them to be identical - no checking is done).
readv() and writev() are really bad match for that.  Unfortunately,
userland API is userland API and we can't do anything about them.

Converted to ->read_iter/->write_iter.  Please, _please_ don't do
anything of that kind when designing new interfaces.

Linus Torvalds 56fd85b5dd ASoC: Last minute fix for v4.0
This patch backs out a change that came in during the merge window which
 selects a configuration for GPIO4 on pcm512x CODECs that may not be
 suitable for all systems using the device.  Changes for v4.1 will make
 this properly configurable but for now it's safest to revert to the
 v3.19 behaviour and leave the pin configuration alone.
 
 Sorry for sending this direct at the last minute but due to the GPIO
 misuse it'd be really good to get it in the release and I'd not realised
 it hadn't been sent yet - between some travel, a job change and other
 non-urgent fixes coming in I'd lost track of the urgency.  It's been in
 -next for several weeks now, is isolated to the driver and fairly clear
 to inspection.

Arnd Bergmann 8616774968 ASoC: rnsd: fix build regression without CONFIG_OF
The r-car sound driver only works when CONFIG_OF is set, and
after a recent change has a compile-time dependency as well:

sound/built-in.o: In function `rsnd_dma_request_channel':
:(.text+0x9fb84): undefined reference to `of_dma_request_slave_channel'

This could be fixed either by adding a static inline wrapper
for the function, or by adding a Kconfig dependency. This
implements the second approach, which seems appropriate
because the driver in fact has a hard dependency.

Takashi Iwai cc7016ab1a ALSA: hda - Fix headphone pin config for Lifebook T731
Some BIOS version of Fujitsu Lifebook T731 seems to set up the
headphone pin (0x21) without the assoc number 0x0f while it's set only
to the output on the docking port (0x1a).  With the recent commit
[03ad6a8c93b6: ALSA: hda - Fix "PCM" name being used on one DAC when
 there are two DACs], this resulted in the weird mixer element
mapping where the headphone on the laptop is assigned as a shared
volume with the speaker and the docking port is assigned as an
individual headphone.

This patch improves the situation by correcting the headphone pin
config to the more appropriate value.

Charles Keepax 1a60667fc8 ASoC: wm8804: Enable runtime PM
Currently both the oscillator and the PLL are powered up in
set_bias_level. This can be problematic when using output clocks from
the wm8804 for other devices. The snd_soc_codec_set_pll API defines that
a clock should be available once the call returns, however, with all the
clocking controlled in set_bias_level this is not currently the case.

This patch enables pm_runtime for the wm8804, enabling both the
regulators and the oscillator when the chip resumes, and enabling the
PLL in the snd_soc_codec_set_pll call. Naturally the enabling the PLL
will also cause the chip to resume.

Sapthagiri Baratam 5631f18763 ASoC: wm8804: Add DAPM widgets for SPDIF/AIF
This change converts the driver to use DAPM to control the power for the
various blocks on the chip. As part of this change the existing controls
"TX Playback Switch" (controlled power for the SPDIF TX block) and "AIF
Playback Switch" (controlled power for the AIF block) are both removed,
as they are now redundant since the power state of those blocks is
controlled automatically by DAPM.

There are several benefits of this change, the most important of which
is this change adds support for powering down the SPDIF RX block. The RX
block will automatically assume control of the PLL on the chip when it
is receiving a signal, so leaving this enabled all the time as was
currently done in the driver can be problematic. An incoming SPDIF signal
that is not being used can completely destroy the clocking for an in use
TX signal. But this change ensures that the RX block will only be
powered when the user intends to be receiving data, thus avoiding this
issue.

Additional benefits include the chip being simpler to operate as the
power no longer needs to be manually controlled between use-cases and a
small power saving (although it is acknowledged that this is likely
unimportant in the typical use-cases for this chip).

Takashi Iwai 664c715573 ALSA: hda - Work around races of power up/down with runtime PM
Currently, snd_hdac_power_up()/down() helpers checks whether the codec
is being in pm (suspend/resume), and skips the call of runtime get/put
during it.  This is needed as there are lots of power up/down
sequences called in the paths that are also used in the PM itself.  An
example is found in hda_codec.c::codec_exec_verb(), where this can
power up the codec while it may be called again in its power up
sequence, too.

The above works in most cases, but sometimes we really want to wait
for the real power up.  For example, the control element get/put may
want explicit power up so that the value change is assured to reach to
the hardware.   Using the current snd_hdac_power_up(), however,
results in a race, e.g. when it's called during the runtime suspend is
being performed.  In the worst case, as found in patch_ca0132.c, it
can even lead to the deadlock because the code assumes the power up
while it was skipped due to the check above.

For dealing with such cases, this patch makes snd_hdac_power_up() and
_down() to two variants: with and without in_pm flag check.  The
version with pm flag check is named as snd_hdac_power_up_pm() while
the version without pm flag check is still kept as
snd_hdac_power_up().  (Just because the usage of the former is fewer.)

Then finally, the patch replaces each call potentially done in PM with
the new _pm() variant.

In theory, we can implement a unified version -- if we can distinguish
the current context whether it's in the pm path.  But such an
implementation is cumbersome, so leave the code like this a bit messy
way for now...

Lars-Peter Clausen a1f0b96749 ASoC: wm8753: Cleanup manual bias level transitions
Set the CODEC driver's suspend_bias_off flag rather than manually going to
SND_SOC_BIAS_OFF in suspend and SND_SOC_BIAS_STANDBY in resume. This makes
the code a bit shorter and cleaner.

Since the ASoC core now takes care of setting the bias level to
SND_SOC_BIAS_OFF when removing the CODEC there is no need to do it manually
anymore either.

The manual transition to SND_SOC_BIAS_STANDBY at the end of CODEC probe()
can also be removed as the core will automatically do this after the CODEC
has been probed.

Lars-Peter Clausen 35afd9221b ASoC: wm8753: Integrate capacitor charging into the DAPM sequence
When being powered on, either initially on probe or when resuming from
suspend, the wm8971 configures the device for quick output capacitor
charging. Since the charging can take a rather long time (up to multiple
seconds) it is done asynchronously without blocking. A delayed work item is
run once the charging is finished and the device is switched to the target
bias level.

This all done asynchronously to the regular DAPM sequence accessing the same
data structures and registers without any looking, which can lead to race
conditions. Furthermore this potentially delays the start of stream on the
CODEC while the rest of the system is already up and running, meaning the
first bytes of audio are lost. It also does no comply with the assumption of
the DAPM core that if set_bias_level() returned successfully the device will
be at the requested bias level.

This patch slightly refactors things and makes sure that the caps charging
is properly integrated into the DAPM sequence. When transitioning from
SND_SOC_BIAS_OFF to SND_SOC_BIAS_STANDBY the part will be put into fast
charging mode and a work item will be scheduled that puts it back into
standby charging once the charging period has elapsed. If a playback or
capture stream is started while charging is in progress the driver will now
wait in SND_SOC_BIAS_PREPARE until the charging is done. This makes sure
that charging is done asynchronously in the background when the chip is
idle, but at the same time makes sure that playback/capture is not started
before the charging is done.

Renesas sound card has "sampling rate convert" feature which

But, sound card driver point of view, it is difficult to add

support is very difficult.

This patch implements DPCM feature on DT as Renesas specific sound card.
This new driver is copied from current simple-card driver.
Main difference between simple-card and this driver are...
 1. removed unused feature from simple-card
 2. removed driver named prefix from DT property
 3. CPU will be FE, CODEC will be BE with snd-soc-dummy
 4. it supports sampling rate convert via .be_hw_params_fixup

Having to set different formats on the CPU side and the CODEC side of a DAI
link is usually indication that something is terribly wrong and in most
cases is a result of a broken driver that implements a set_fmt() callback
which does not follow the specification. In the past this feature has been
used to work around broken drivers, rather than fixing them. We don't really
want to encourage this, so remove support for setting different formats on
both ends of the link.

Along the way switch to static DAI format setup by setting the the dai_fmt
field of the snd_soc_dai_link rather than calling snd_soc_dai_fmt().

Current soc_init_card_debugfs() is called from snd_soc_register_card()
but, soc_cleanup_card_debugfs() is called from soc_cleanup_card_resources(),
not from paired function.

This differences don't matter for now. But if anyone wants to implement
a proper hotplug/unplug, this difference would become clearer.

Now, we can assume that snd_soc_instantiate_card() and
soc_cleanup_card_resources() are paired function.
soc_init_card_debugfs() / soc_cleanup_card_debugfs() paired function
should be called from these.

Set rule constraints to allow only combinations of sample-rate,
sample-format, and channels counts that can be played/captured with
reasonable sample-rate accuracy.

The logic with tdm-slots and serializers (=i2s data wires) goes like
this: The first wire will take all channels up to number of tdm-slots,
before following wires (if any) are used. If the first wire is used
fully, the remaining wires share the same clocks and the divider can
be calculated for the first wire.

Also, takes the number of tdm-slots into account when implicitly
selecting the BLCK divider.

The 16bit COEF read/write is pretty standard for many codecs, and they
can be cached in most cases -- more importantly, they need to be
restored at resume.  For making this easier, add the cache support to
regmap.  If the codec driver wants to cache the COEF access, set
codec->cache_coef flag and issue AC_VERB_GET_PROC_COEF with the coef

Takashi Iwai 33f8194006 ALSA: hda - Handle get/set power verb symmetrically via regmap
HD-audio has quite a few asymmetrical ways of accessing verbs, and one
of typical ones is GET/SET_POWER_STATE verbs.  While it takes only the
power state for setting, it returns a combination of states for
getting.  For making the state handling simpler, this patch adds a
code to translate the value returned from GET_POWER_STATE to return
only the actual state or -1 for error.  In that way, the driver can
simplify the power state management.

Takashi Iwai d313e0a88d ALSA: hda - Add a fake stereo amp register support
HD-audio spec is inconvenient regarding the handling of stereo volume
controls.  It can set and get only single channel at once (although
there is a special option to set the same value to both channels).
This patch provides a fake pseudo-register via the regmap access so
that the stereo channels can be read and written by a single call.
It'd be useful, for example, for implementing DAPM widgets.

A stereo amp pseudo register consists of the encoding like the normal
amp verbs but it has both SET_LEFT (bit 13) and SET_RIGHT (bit 12)
bits set.  The regmap reads and writes a 16bit value for this pseudo
register where the upper 8bit is for the right chanel and the lower
8bit for the left channel.

Note that the driver doesn't recognize conflicts when both stereo and
mono channel registers are mixed.  Mixing them would certainly confuse
the operation.  So, use carefully.

Takashi Iwai a551d91473 ALSA: hda - Use regmap for command verb caches, too
Like the previous patches, this patch converts also to the regmap, at
this time, the cached verb writes are the target.  But this conversion
needs a bit more caution than before.

- In the old code, we just record any verbs as is, and restore them at
  resume.  For the regmap scheme, this doesn't work, since a few verbs
  like AMP or DIGI_CONVERT are asymmetrical.  Such verbs are converted
  either to the dedicated function (snd_hda_regmap_xxx_amp()) or
  changed to the unified verb.

- Some verbs have to be declared as vendor-specific ones before
  accessing via regmap.

Also, the minor optimization with codec->cached_write flag is dropped
in a few places, as this would confuse the operation.  Further
optimizations will be brought in the later patches, if any.

This conversion ends up with a drop of significant amount of codes,
mostly the helper codes that are no longer used.

Takashi Iwai faa75f8a2e ALSA: hda - Use regmap for parameter caches, too
The amp hash table was used for recording the cached reads of some
capability values like pin caps or amp caps.  Now all these are moved
to regmap as well.

One addition to the regmap helper is codec->caps_overwriting flag.
This is set in snd_hdac_override_parm(), and the regmap helper accepts
any register while this flag is set, so that it can overwrite even the
read-only verb like AC_VERB_PARAMETERS.  The flag is cleared
immediately in snd_hdac_override_parm(), as it's a once-off flag.

Along with these changes, the no longer needed amp hash and relevant
fields are removed from hda_codec struct now.

Takashi Iwai eeecd9d10d ALSA: hda - Use regmap for amp accesses
This patch converts the amp access functions to the regmap helpers.
The amp values were formerly cached in the own hash table.  Now it's
dropped by the regmap's cache.

The only tricky conversion is snd_hda_codec_amp_init().  This function
shouldn't do anything if the amp was already initialized.  For
achieving this behavior, a value is read once at first temporarily in
the cache-only mode.  Only if it returns an error,  i.e. the item
still doesn't exist in the cache, it proceeds to the update.

Takashi Iwai 4d75faa044 ALSA: hda - Add regmap support
This patch adds an infrastructure to support regmap-based verb
accesses.  Because o the asymmetric nature of HD-audio verbs,
especially the amp verbs, we need to translate the verbs as a sort of
pseudo registers to be mapped uniquely in regmap.

In this patch, a pseudo register is built from the NID, the
AC_VERB_GET_* and 8bit parameters, i.e. almost in the form to be sent
to HD-audio bus but without codec address field.  OTOH, for writing,
the same pseudo register is translated to AC_VERB_SET_* automatically.
The AC_VERB_SET_AMP_* verb is re-encoded from the corresponding
AC_VERB_GET_AMP_* verb and parameter at writing.

Some verbs has a single command for read but multiple for writes.  A
write for such a verb is split automatically to multiple verbs.

The patch provides also a few handy helper functions.  They are
designed to be accessible even without regmap.  When no regmap is set
up (e.g. before the codec device instantiation), the direct hardware
access is used.  Also, it tries to avoid the unnecessary power-up.
The power up/down sequence is performed only on demand.

The codec driver needs to call snd_hdac_regmap_exit() and
snd_hdac_regmap_exit() at probe and remove if it wants the regmap
access.

There is one flag added to hdac_device.  When the flag lazy_cache is
set, regmap helper ignores a write for a suspended device and returns
as if it was actually written.  It reduces the hardware access pretty
much, e.g. when adjusting the mixer volume while in idle.  This
assumes that the driver will sync the cache later at resume properly,
so use it carefully.
