NEO3 OTG headers working with modified DTB

[djjerdog]

I manged to get the USB OTG headers working on the NEO3 by modifying the NanoPi R2S DTB that it is currently using.

 

2 changes were needed:

- Replaced all usb2 references to usb0

- Changed dr_mode for usb@ff580000 from otg to peripheral

 

Modified DTB file attached if anyone else wants to give this a try or has a need for OTG on the NEO3

if anyone else

Forum is a black hole. If you want that this contribution is not lost, make it way to the build script. As a patch or as an overlay.

Is it possible to get the patched .dts file at least ? This way, we could create a patch and integrate it to the armbian build tree.
