This device works like any V4L2 driver, with the differences explained
here:
https://linuxtv.org/downloads/v4l-dvb-apis-new/uapi/v4l/dev-sdr.html
For the rest I'm no expert. You can probably port dab2eti to use this
interface instead of librtlsdr and keep the rest. You may be able to
skip an fft if your driver supports it, otherwise you'll get RU12, that
you'll probably have to convert to floats before passing to the rest of
the processing code.
regards,
Nicolas
