Just for my understanding, are you suggesting to set a device tree property to force a fixed behavior in the driver ?
WM8904 allows using both a DMIC and LINEIN, switching between one or the other and this is how we currently use it.
Why the user should not be allowed to switch between DMIC and LINEIN ?
