We've had the policy so far to send the DT to upstream's kernel first.

Most notably, the biggest issue I have with this DT is its name, which
is going to be an issue if we ever change it in Linux. The SOM WiFi
module is using USB, therefore it doesn't have any difference compared
to the SOM itself.

Why not just create a DT and defconfig for the SOM, wifi or not?
