These parameters are exposed considering the fact that DMIC itself is not part of the codec. Codec only provides DMIC interface using which an external DMIC can be attached. These parameters depend on the actual DMIC hardware and hence kept configurable to allow runtime plug in of any DMIC hardware. Doesn't it make sense to keep them runtime configurable?

Can you explain which value / user supplied value you are referring to? It is not quite clear to me.
- also, what happens if the
user sets the device to slave mode after setting up the PLL?
Will add required checks in set_fmt().

I guess here a DAPM_SUPPLY widget should be used and its routing should be part of machine driver instead of this codec driver, right?
For other things like input mixers, Headphone and Lineouts, DAPM is already used to control power specific bits. The confusion is because there are two separate control bits for these blocks. One bit is for "Enabling" that block and other is for "Enabling Amplifier" of that block. e.g for headphone, one bit is for "output enable" while other is for "output amplifier enable".
Chip designers have confirmed that "Amplifier Enable" bits are ones which should be used for power management. This is the reason why "Enable" bits are being set in probe() and "Amplifier Enable" bits are being taken care by DAPM. May be I need to put enough comments in code to clarify this.

No. The only realistic way to attach a new DMIC to a board is to solder it down, that's not something people are going to do while the system is actve. It's something that's fixed at PCB design time.

The specified output frequency, you just totally ignore it.

So document this.

DAPM.
Here the trouble in making it DAPM based is that there is no separate control for AIF input and output. It is confirmed that AIF_EN is the master control bit, which enables both output as well as input. The AIF _OE bit is redundant. If we use the same control bit(i.e AIF_EN) for both DAPM_AIF_IN and DAPM_AIF_OUT, there will be obvious side effects. Is there any other way to take care of this? Or should we leave it outside DAPM?
