My understanding is upstream kernel, as used in openSUSE, cannot apply DT overlays at runtime. You need to update your DTB, or create a fragment and merge it with your current DT. Then, use this new DTB to boot your board. Cheers, Guillaume > > > -- > Per Jessen, Zürich (7.1°C) > Member, openSUSE Heroes.

I think you need to create/update /boot/efi/extraconfig.txt file to enable I2S
and select the right DAC:
dtparam=i2s=on

AArch64 images from latest Tumbleweed snapshot should be fine:

[opensuse-arm] Pimoroni pHAT DAC on Raspberry Pi 3
Hi All Has anyone had any luck getting Pimoroni accessories such as "pHAT DAC" working on Raspberry Pi 3 under recent opensuse images? This is a PCM5102A DAC connected via I2S interface, the Pimoroni instructions are specific to Raspian. Separately, can anyone advise the latest image (JeOS is fine) that runs OK on the model 3? I've been very happy with JeOS armv6l-2019.07.31-Snapshot20190814 on my model 1B but still using a much older image on the model 3 as nothing I have tried recently will boot.

There are some information about 1-wire here:
https://en.opensuse.org/openSUSE:1-wire
If you want to use 1-wire on a regular gpio, with w1-gpio module, you need to
update your device-tree to setup it properly.
Then, you can check /sys/bus/w1/devices folder for any devices found on the
1-wire bus.
If you do not update your DTB, w1-gpio will not know which gpio to use.

Guillaume
