The Creative Audigy SE (SB0570) card currently exhibits an audible pop
whenever playback is stopped or resumed, or during silent periods of an
audio stream. Initialise the IZD bit to the 0 to eliminate these pops.

The Infinite Zero Detection (IZD) feature on the DAC causes the output
to be shunted to Vcap after 2048 samples of silence. This discharges the
AC coupling capacitor through the output and causes the aforementioned
pop/click noise.

The behaviour of the IZD bit is described on page 15 of the WM8768GEDS
datasheet: "With IZD=1, applying MUTE for 1024 consecutive input samples
will cause all outputs to be connected directly to VCAP. This also
happens if 2048 consecutive zero input samples are applied to all 6
channels, and IZD=0. It will be removed as soon as any channel receives
a non-zero input". I believe the second sentence might be referring to
IZD=1 instead of IZD=0 given the observed behaviour of the card.

This change should make the DAC initialisation consistent with
Creative's Windows driver, as this popping persists when initialising
the card in Linux and soft rebooting into Windows, but is not present on
a cold boot to Windows.

In a development period for Linux kernel v4.20, drivers in ALSA firewire
stack were changed to wait for releases of all ALSA character devices at
.remove callback of bus driver. However, ALSA dice driver is partly out
of this change. This bug can bring fault to user process which holds
the last of character device in unplugging.

This commit fixes the driver to wait in the callback.

ASoC: Updates for v5.0/v4.20

As ever there's a lot of small and driver specific changes going on
here, but we do also have some relatively large changes in the core
thanks to the hard work of Charles and Morimoto-san:

 - More component transitions from Morimoto-san, I think we're about
   finished with this.  Thanks for all the hard work!
 - Morimoto-san also added a bunch of for_each_foo macros
 - A bunch of cleanups and fixes for DAPM from Charles.
 - MCLK support for several different devices, including CS42L51, STM32
   SAI, and MAX98373.
 - Support for Allwinner A64 CODEC analog, Intel boards with DA7219 and
   MAX98927, Meson AXG PDM inputs, Nuvoton NAU8822, Renesas R8A7744 and
   TI PCM3060.

This patch fixes the microphone issue for all cards. The previous fix
worked on the ZxR, but not on the AE-5 or Z. This patch has been tested
to work for all cards.

The wm_adsp_buffer struct is the control header of a circular
buffer used to transfer data from the firmware over the
control interface to an ALSA compressed stream.

The original names of the fields pointing to the data buffer
were based on ADSP2V2 memory layout where they correspond to
{XM, XM, YM}. But this circular buffer could be used on other
types of DSP core that have different memory region types.
Also the names and description of the size fields were not
very clear. The field names and descriptions have been changed
to be generic and not imply any particular memory types.

This patch updates the wm_adsp driver to the new field names.

Then, SSI parent needs control WS/CLK setting for SSI slave.
In such case, SSI parent needs TDM settings if SSI slave is working as

The STA32x chips feature an XTI clock input that needs to be stable before
the reset signal is released. Therefore, the chip driver needs to get a
handle to the clock. Instead of relying on other parts of the system to
enable the clock, let the codec driver grab a handle itself.
