da369d0ab5 ASoC: rt5645: set high voltage for capless power
The default capless power mode is low voltage mode. We should set
it to high voltage mode to get fair headphone performance.

02c5c03283 ASoC: rt5645: set sel_i2s_pre_div1 to 2
The i2s clock pre-divider 1 is used for both i2s1 and sysclk.
The i2s1 is usually used for the main i2s and the pre-divider
will be set in hw_params function.

However, if i2s2 is used, the pre-divider is not set in the hw_params
function and the default value of i2s clock pre-divider 1 is too high
for sysclk and DMIC usage. Fix by overriding default divider value to 2.

af813a6fd8 ASoC: wm_adsp: Add mechanism to preload firmware on a core
As requirements to bring up audio paths are continuous getting tighter
and the DSP download to most ADSP devices happens over an external bus
it can become an important factor in the path bring up time. As such
sometimes it is a reasonable trade off to download the firmware ahead of
when it will be required and take a small hit on power consumption for
keeping the core powered up.

This "preloading" adds an additional control for each DSP core "DSPx
Preload Switch" that when set to true will power up the DSP core and
download the firmware currently selected in the "DSPx Firmware" control.
Whilst the core is preloaded the current firmware can not be changed and
the CODEC will be kept powered up and SYSCLK held on. Although future
improvements may allow the SYSCLK to be powered down as well because
the hardware only requires SYSCLK whilst the download is actually taking
place, but this is not covered in this series.

ac29a8f417 ASoC: da7218: Set DAI output pin high impedance when not in use
For TDM mode, the I2S data out line can be shared between mutliple
codecs. In this scenario, only the active codec should be using
the line, and all others should be high impedance. However,
currently in the driver this configuration isn't set when capture
is inactive, and the line remains driven.

This patch updates the AIF_OUT widget to set the DAI output pin of
the device as high impedance when not in use.

Pull sound updates from Takashi Iwai:
 "No dramatic changes are found in this development cycle, but as usual,
  many commits are applied in a wide range of drivers.

  Most of big changes are in ASoC, where a few bits of framework work
  and quite a lot of cleanups and improvements to existing code have
  been done. The rest are usual stuff, a few HD-audio and USB-audio
  quirks and fixes, as well as the drop of kthread usages in the whole
  subsystem.

  Below are some highlights:

  ASoC:
   - support for stereo DAPM controls
   - some initial work on the of-graph sound card
   - regmap conversions of the remaining AC'97 drivers
   - a new version of the topology ABI; this should be backward
     compatible
   - updates / cleanups of rsnd, sunxi, sti, nau8825, samsung, arizona,
     Intel skylake, atom-sst
   - new drivers for Cirrus Logic CS42L42, Qualcomm MSM8916-WCD, and
     Realtek RT5665

  USB-audio:
   - yet another race fix at disconnection
   - tolerated packet size calculation for some Android devices
   - quirks for Axe-Fx II, QuickCam, TEAC 501/503

  HD-audio:
   - improvement of Dell pin fixup mapping
   - quirks for HP Z1 Gen3, Alienware 15 R2 2016 and ALC622 headset mic

  Misc:
   - replace all kthread usages with simple works"

8c317fafdd ASoC: cs42l56: Fix misuse of regmap_update_bits
Using regmap_update_bits(..., mask, 1) with 'mask' following (1 << k)
and k greater than 0 is wrong. Indeed, _regmap_update_bits will perform
(mask & 1), which results in 0 if LSB of mask is 0. Thus the call
regmap_update_bits(..., mask, 1) is in reality equivalent to
regmap_update_bits(..., mask, 0).

In such a case, the correct use is regmap_update_bits(..., mask, mask).

This driver is performing such a mistake with the CS42L56_AIN*_REF_MASK
masks, which equal 0x10, 0x20, 0x40 and 0x80. Fix the driver to make it
consistent with the API. Please note that this change is untested,
as I do not have this piece of hardware. Testers are welcome!

2263fddcd0 ASoC: nau8825: lock longer to avoid playback pop upon resume
There is an issue about pop noise in NAU88L25 as follows.
Issue 54078: Chell_headphone pop back from S3
(1)Play directly to hw, bypassing CRAS:
sox -b 16 -n -t alsa hw:0,0 synth sine 200 sine 200
(2)Close lid or powerd_dbus_suspend, then press a key to resume.
(3)no audio after resume
(4)Audio will be back after close then reopen the pcm device.

After verification, we find one defect is that semaphone lock is not
long enough and expired. In this situation, the playback comes back
early but pauses a while to wait for the crosstalk detection done.
But the detection spends too much time and lock time is up. Therefore,
the playback and jack detection sequence interfere to each other.
That breaks sequence and makes noise. The driver extends the lock
time for the issue.

Disable IRQ when jack is NULL in rt298_mic_detect. So machine driver
can use it in suspend/resume.

0a69516cd8 ASoC: ab8500: Remove explicit initialization of driver callbacks to NULL
Fields of structs with global storage are implicitly initialized to 0/NULL,
there is usually no need to do this explicitly.

Removing the initialization of the legacy suspend/resume callback fields
also gets the driver ready for the day when they are eventually removed.
