I already have BPI-P2-Zero device tree and kernel config ready. At least for board revision 1.1. The version 1.0 has some hardware issues and differences. My current test image is based on Yocto/OpenEmbedded. I plan to send DT upstream and then I want look how to build Armbian for this board.

I have PCM5102a DAC I would like to use with my OrangePI PC. I currently use latest mainline from armbian. Can someone guide me a little how to get it work? Do I need to additional kernel modules for DAC to work? Or all I need is to provide DT overlay? Something like it was done here: https://github.com/codekipper/linux-sunxi/commit/a2142b12269970daa1e3895a413a7e19230f9530 EDIT: Ups. I just noticed this thread is in devel section. So If nobody replies I will ask in support group.

Maybe I could also try to do something. I have a orangepi pc board and I would like to get i2s working which should be supported in 4.14. So if I get it right I get upstream mainline kernel then apply patches from "build/patch/kernel/sun8i-dev/". If everything goes fine I will add device trees from sunxi-DT-overlays repository and test the kernel?

I was not aware of overlays. It works. Thanks a lot.

Hello. I have installed debian based armbian with mainline kernel to my orange pi zero. And it seems like there is no i2c adapter present. As far I know it should work in mainline. Does anyone have a clue?
