had to move it to 4.18 though.

The change to the dt-binding header goes through the networking
tree and will only get merged for 4.17-rc1 .

So devicetree changes in a different branch aren't available at this
point.

One commonly practiced alternative is that you provide a v2
with the actual hex values instead of the constants for 4.17
and a follow-up patch replacing them with the constants
that I can apply for 4.18.
