I2S soundcard overlay

Hi all,

Im trying to get this i2s card to work with the rock pi E.

https://www.audiophonics.fr/en/devices-hifi-audio-adc/adc-analog-to-digital-converter-wm8782-i2s-24bit-192khz-p-13351.html

The i2s card is the master in my setup.

I’m running Debian.

Can anybody point me in the right direction as to how the overlay needs to look like ?
Thanks !
