X98 Mini - S905W2

[dolaru]

Hello 👋🏽. I've got my hands on an X98 mini box and I'm trying to get a mainline kernel running on it, but there doesn't seem to be a suitable DTB around.

Snooping around the device tree in the Android distribution that came on it I found references to S4 and AP201. and there is a device tree definition for AP201 here.

The mainline kernel seems to have the S4 base.

Any advice on what the next steps would be to get a suitable device tree image built for this box?
