iio-oscilloscope: AD9684: Should I write a device specific plugin?

I am using the generic iio-scope interface for selecting an AD9684 device (axi-ad9684-core-lpc).

However, I'm facing issues with the sinewave input not being displayed correctly.

Is the data received using libiio processed further by additional board specific pluging (e.g. FMCOMMS1, FMCOMMS2/3/4) to get the data to display correctly?
