I see in the ADAU1781 driver wiki page that I2S communication is supported. I wanted to ask what steps I would need to take to make this work with a Raspberry Pi. The end goal is to use the ADAU1781 as an audio I/O hat, working through the GPIO pins that is recognized by alsa, such that it shows up as an audio device under aplay -l.
What steps do I need to take both in terms of pin connection (to set up I/O and proper clocking) and within the Raspberry Pi's linux system to make this work?
I am using the ADAU1781 dev board and a Raspberry Pi 3 model B which has the following pinout: https://www.element14.com/community/servlet/JiveServlet/previewBody/73950-102-10-339300/pi3_gpio.png
