Recently, I upgraded Armbian on my Orange Pi Plus to the nightly dev build. I quickly found out that the 1-wire gpio doesn't work. The http://linux-sunxi.org/1-Wire gave me some hints where to look for. I decompiled the DTB to check if the device definition is there. It was not, so I added the pieces from the manual (adjusting them a bit - changing port, replacing constants with raw values) and recompiled back to /boot/dtb/sun8i-h3-orangepi-plus.dtb. It works great.
I fought, I could contribute to Armbian by preparing patch, so I've modified arch/arm/boot/dts/sun8i-h3.dtsi and made a diff. Looking for the place to post it I found this topic and I started to wonder if the DDT Overlays wouldn't be a better way to start 1-wire. It's not a functionality that everyone needs and enabling it on demand would be a better approach.
What do you suggest? How to implement it with Overlays? Does Armbian building tools have functionality to build dtbo's?
