If MCLK is derived from SCLK, whether the 'MCLK' pin on the device is
connected or not has no effect on operation.

The value of everest,hpfl is equal to the value of the corresponding register,
not the cutoff frequency of the HPF.
The code does not specify which register corresponds to which HPF cutoff frequency.
And we did not set the HPF to kcontrol because we do not want users to be able to control it
while the codec is running.

OK
