ASoC: codec: hdac_hdmi: no checking monitor in hw_params
Some userspace apps, like pulseaudio, may call open, hw_params,
prepare to judge whether the pcm is ready or not. Current hdac_hdmi
will return -ENODEV if monitor is not connected, which will cause
the apps believe the pcm is not ready. Actually PCM for hdmi is ready,
even the monitor is not connected.

This patch removes the check of monitor presence in hw_params, just like
what the legacy HD-Audio driver does.

ASoC: mediatek: mt6358: save output volume for mixer controls
Output volume settings from mixer controls would be lost.

Imagine that "Headphone Volume" has set to -10dB via amixer:
- in mtk_hp_enable()
  - hp_store_gain() saves the volume setting -10dB from regmap_read()
    to ana_gain[AUDIO_ANALOG_VOLUME_HPOUTL]
  - headset_volume_ramp() ramps up from -10dB to -10dB
- in mtk_hp_disable()
  - headset_volume_ramp() ramps down from -10dB to -40dB

Next time in mtk_hp_enable(), hp_store_gain() would save -40dB but
not -10dB.  As a result, headset_volume_ramp() would ramp from -10dB to
-40dB (which is mute).

ASoC: mediatek: mt6358: initialize setting when ramping volume
Mt6358 ramps up from the smallest volume (i.e. -10dB) to target dB when
opening and ramps down from target dB to mute (i.e. -40dB) when closing.
If target is equal to -10dB when opening, headset_volume_ramp() simply
leaves current setting (which may not be -10dB) unchanged.

Execute the loop at least once to initialize the setting to the
starting point (i.e. from).

ASoC: max98090: Fix restore of DAPM Muxes
The max98090 driver defines 3 DAPM muxes; one for the right line output
(LINMOD Mux), one for the left headphone mixer source (MIXHPLSEL Mux)
and one for the right headphone mixer source (MIXHPRSEL Mux). The same
bit is used for the mux as well as the DAPM enable, and although the mux
can be correctly configured, after playback has completed, the mux will
be reset during the disable phase. This is preventing the state of these
muxes from being saved and restored correctly on system reboot. Fix this
by marking these muxes as SND_SOC_NOPM.

Note this has been verified this on the Tegra124 Nyan Big which features
the MAX98090 codec.

ASoC: RT5677-SPI: Disable 16Bit SPI Transfers
The current algorithm allows 3 types of transfers, 16bit, 32bit and
burst. According to Realtek, 16bit transfers have a special restriction
in that it is restricted to the memory region of
0x18020000 ~ 0x18021000. This region is the memory location of the I2C
registers. The current algorithm does not uphold this restriction and
therefore fails to complete writes.

Since this has been broken for some time it likely no one is using it.
Better to simply disable the 16 bit writes. This will allow users to
properly load firmware over SPI without data corruption.

ASoC: da7219: Use clk_round_rate to handle enabled bclk/wclk case
For some platforms where DA7219 is the DAI clock master, BCLK/WCLK
will be set and enabled prior to the codec's hw_params() function
being called. It is possible the platform requires a different
BCLK configuration than would be chosen by hw_params(), for
example S16_LE format needed with a 64-bit frame to satisfy certain
devices using the clocks.

To handle those kinds of scenarios, the use of clk_round_rate() is
now employed as part of hw_params(). If BCLK is already enabled
then this function will just return the currently set rate, if it
is valid for the desired frame size, so the subsequent call to
clk_set_rate() will succeed and nothing changes with regards to
clocking. In addition the specific BCLK & WCLK recalc_rate()
implementations needed updating to always give back a real value,
as those functions are called as part of the clk init code and a
real value is needed for the clk_round_rate() call to work as
expected.

ASoC: wm_adsp: Avoid calling snd_compr_stop_error from WDT expiry
It is unsafe to call snd_compr_stop_error from outside of the
compressed ops. Firstly the compressed device lock needs to be held
and secondly it queues error work to issue a trigger stop which
should not happen after the stream has been freed. To avoid these
issues use the same trick used for the IRQ handling, simply send a
snd_compr_fragment_elapsed to cause user-space to wake on the poll,
then report the error when user-space issues the pointer request
after it wakes.

ASoC: cs42l51: add multi endpoint support
Support multiple endpoints on cs42L51 codec port
when used in of_graph context.

This patch allows to share the codec port between two CPU DAIs.

Example:

STM32MP157C-DK2 board uses CS42L51 audio codec.
This codec is connected to two serial audio interfaces,
which are configured either as rx or tx.

From AsoC point of view the topolgy is the following:
// 2 CPU DAIs (SAI2A/B), 1 Codec (CS42L51)
Playback: CPU-A-DAI(slave) -> (master)CODEC-DAI/port0
Record:   CPU-B-DAI(slave) <- (master)CODEC-DAI/port0

In the DT two endpoints have to be associated to the codec port:
cs42l51_port: port {
	cs42l51_tx_endpoint: endpoint@0 {
		remote-endpoint = <&sai2a_endpoint>;
	};
	cs42l51_rx_endpoint: endpoint@1 {
		remote-endpoint = <&sai2b_endpoint>;
	};
};

However, when the audio graph card parses the codec nodes, it expects
to find DAI interface indexes matching the endpoints indexes.

The current patch forces the use of DAI id 0 for both endpoints,
which allows to share the codec DAI between the two CPU DAIs
for playback and capture streams respectively.

The common pins were mistakenly not added to the DAPM graph.
Adding these pins will allow valid graphs to be created.

ASoC: tlv320aic32x4: Only enable with common clock
Some architectures do not yet support the common clock API at all but
the tlv320aic32x4 driver now requires it.
