You’ll need to write a new ASoC driver if the I2S device isn’t compatible with the bcm2835 one, which is pretty likely. The UDRC glue driver source is at:
You’ll also need to set up the device tree to link up the correct i2c device to the whole thing and cause it to load. See the UDRC’s device tree
You might also be able to hack up a device tree using the ASoC simple_card driver to glue them both together instead. See the docs at https://github.com/nwdigitalradio/linux/blob/master/Documentation/devicetree/bindings/sound/simple-card.txt.
Note that while sometimes you might get me to opine vaguely about possibilities and where to look, neither I nor NWDR support using the DRAWS/UDRC on anything but a RPi.
