In MT8195 SOF design, both DSP and audio driver would access audio
registers. Before DSP accesses audio registers, audio power and clock
should be enabled. DSP will hang up if DSP access audio register but
audio power and clock are disabled. Therefore, we add audio pm runtime
active checking before accessing audio registers in SOF BE's callback
hw_params function to avoid this situation.

The ASoC core automatically populates the driver name field in the card
from the card name if left unset. However, since the driver name can be
at most 16 characters long, wrapping will happen if the card name is
longer, which is the case for the mt8192-mt6359 driver.
Explicitly set the driver name for the card in order to avoid said

Audio tuner is used to handle clock drift between 26M and APLL domain.
It's expected when abs(chg_cnt) equals to upper bound, tuner updates pcw
setting automatically, and then abs(chg_cnt) decreases.
In the stress test, we found abs(chg_cnt) possibly equals to 2 at the
unexpected timing. This results in wrong pcw updating.
Finally, abs(chg_cnt) will always be larger than upper bound,
As a result, we update the upper bound to 3 to handle the corner case.

The rt5682 codec is able to distinguish between two event types:
headphone insertion/removal and headset microphone insertion/removal.
However, currently, the mt8186-rt5682 driver exposes a single kcontrol
for the headset jack, so userspace isn't able to differentiate between
the two events.
Add a definition for the headset jack pins, so that a separate jack
kcontrol is created for each one, allowing userspace to track and handle
them individually.

The "i2s_priv" pointer cannot be NULL. Some NULL checks were deleted
in commit d7bffbe9cb ("ASoC: mediatek: mt8186: remove unnecessary
judgments") but this one was accidentally left behind.

The afe_priv->dai_priv[] is allocated when platform driver probe(), if it
failed, the ASoC platform driver probe() will return fail first.
Therefore, this is excessive judgment, and the condition will never be
established.

This is a semi-automatic email about new static checker warnings.
The patch ae92dcbee8b6: "ASoC: mediatek: mt8186: support tdm in
platform driver" from May 23, 2022, leads to the following Smatch

Fix Smatch static checker warning. strncmp() here only needs to compare
the first seven bytes, so in order to make the code more clear, only the
first seven bytes of the string used as the comparison are reserved.
