14f0413ce3 ASoC: pcm512x: Remove hardcoding of pll-lock to GPIO4
Currently GPIO4 is hardcoded to output the pll-lock signal.
Unfortunately this is after the pll-out GPIO is configured which
is selectable in the device tree. Therefore it is not possible to
use GPIO4 for pll-out. Therefore this patch removes the
configuration of GPIO4.

99dcab46b5 ALSA: emu10k1: add toggles for E-mu 1010 optical ports
The optical ports on the E-mu 1010 (and dock) can be configured
for ADAT- or S/PDIF-mode, which is currently hardcoded to ADAT.
Add two mixer elements to expose this setting.
Tested on an E-mu 1010 PCIe with connected Micro Dock.

currently some members related identical information are not fiiled
in returned parameter of SNDRV_CTL_IOCTL_ELEM_ADD. This is not better
for userspace application.

This commit copies information to returned value. When failing to copy
into userspace, the added elements are going to be removed. Then, no
applications can lock these elements between adding and removing because
these are already locked.

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
[03ad6a8c93: 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.

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.

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).

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...

8e64aedf80 ASoC: Intel: Fix a buffer overflow issue
0day robot reported a buffer overflow issue:

...
sound/soc/intel/haswell/sst-haswell-pcm.c:1107 hsw_pcm_probe() error: buffer\
overflow 'hsw_dais' 4 <= 4
sound/soc/intel/haswell/sst-haswell-pcm.c:1109 hsw_pcm_probe() error: buffer\
overflow 'hsw_dais' 4 <= 4
...

Fix it by initializing the index(i) to correct value.

142267c9e0 ALSA: hda - Create AFG sysfs node at last
... so that user-space can know that the whole nodes have been
created.  Unfortunately, this can't be implemented easily in race-free
way, so it's a kind of compromise.
