Thus, AUDMUX needs to save all the values of registers before the
system suspend and restore them after the system resume.

ASoC: SOF: Intel: initial support for Elkhart Lake
Add Kconfig, PCI ID and chip info for EHL platform.
Note that the core mask is different from previous platforms, only
Core0 can be controlled by the host. Additional patches will be
required for multi-core functionality.

The only configuration parameter is the ALH stream ID. No range
checking is done by the driver, the firmware should check that the
stream is valid for a specific hardware.
Bump the ABI Minor number to keep the alignment with SOF firmware

ASoC: core: Move pcm_mutex up to card level from snd_soc_pcm_runtime
The pcm_mutex is used to prevent concurrent execution of snd_pcm_ops
callbacks. This works fine most of the cases but it can not handle setups
when the same DAI is used by different rtd, for example:
pcm3168a have two DAIs: one for Playback and one for Capture.
If the codec is connected to a single CPU DAI we need to have two dai_link
to support both playback and capture.
In this case the snd_pcm_ops callbacks can be executed in parallel causing
unexpected races in DAI drivers.
By moving the pcm_mutex up to card level this can be solved
while - hopefully - not breaking other setups.

ASoC: mediatek: mt6358: add delay after dmic clock on
Most dmics produce a high level when they receive clock. The difference
between power-on and memory record time is about 10ms, but the dmic
needs 50ms to output normal data.
This commit add 100ms delay after SoC output clock so that we can cut
off the pop noise at the beginning.
