The Hardware Voice Activity Detector (HWVAD) is a block
responsible for detect voice activity in a channel selected
by the user. It can be configured in Envelope-based or
Energy-based mode.
There are additional two interrupts for HWVAD, one is event
interrupt, another is error interrupt.
Enable hwvad in parallel with recording.
when voice activity detected, HWVAD will be disabled and
alsa control notification is triggerred.

For the quality setting the quality setting register values are directly
exposed to the kcontrol and thus to userspace. This is unfortunate
because the register settings contains invalid bit combinations marked
as "N/A". For userspace it doesn't make much sense to be able to set
these just to see that the driver responds with "Please make sure you
select a valid quality." in the kernel log.
Work around this by adding get/set functions for the quality setting.

The reference manual has this for calculating the micfil internal clock
divider:
MICFIL Clock rate
clkdiv = -----------------
8 * OSR * outrate
(with OSR == Oversampling Rate, outrate == output sample rate)
The driver first sets the MICFIL Clock rate to (outrate * 1024) and then
calculates back the clkdiv value from the above calculation.
Simplify this by using a fixed clkdiv value of 8 and set the MICFIL
Clock rate to (outrate * clkdiv * OSR * 8).
While at it drop disabling the clock before setting its rate. The MICFIL
module is disabled when the rate is changed and it is also resetted
before it is started again, so I doubt it's necessary to disable the
clock.

There is no defer probe when adding platform component to
snd_soc_pcm_runtime(rtd), the code is in snd_soc_add_pcm_runtime()
snd_soc_register_card()
-> snd_soc_bind_card()
-> snd_soc_add_pcm_runtime()
-> adding cpu dai
-> adding codec dai
-> adding platform component.
So if the platform component is not ready at that time, then the
sound card still registered successfully, but platform component
is empty, the sound card can't be used.
As there is defer probe checking for cpu dai component, then register
platform component before cpu dai to avoid such issue.
