You should have left my Reviewed-by off in this case. I haven't
actually seen this patch. You could have possibly added "Suggested-by"
or just left me off entirely until I gave you the tag.

I probably would have added this in patman:

Series-changes: 4
-  eth3915n dt bindings added in v4.

Without that you get the "(no changes from v1)" which is always weird
since this patch is new for v4.

This is not quite right because for elan,ekth3915 you're expecting
device trees to have:

compatible = "elan,ekth3915", "elan,ekth3500"

In other words it's actually a 3915 but the 3500 driver should work
fine. I believe a reasonable syntax is:

  compatible:
    oneOf:
      - enum:
          - elan,ektf3624
          - elan,ekth3500
      - items:
          - const: elan,ekth3915
          - const: elan,ekth3500
