Thank you Kenneth.

While the test example files are not ideal for me (as it is test related and I am not familiar with this environment) I was able to compile it and compare graphic device tree to my file. This let me to notice that the ACLK issue is a result of it being dedicated to 53 Series. I simple removed

clock-source = "ACLK";

It compiled with my custom board file and I see clocks ect at the pins.

Hello,

Can you take a look at the i2s driver test examples for example?
C:\ncs\v3.0.0\zephyr\tests\drivers\i2s

I can see there are board files for the nRF54L15DK.
