First, I'm not sure why you combined everything. A maintainer can just
as easily take a series as a single patch and we prefer binding doc,
dts and driver changes all separate.

Second, the dts changes could go thru arm-soc and the driver change
thru netdev. The binding doc can be thru either. There's no bisecting
dependency and things shouldn't break. It just won't all work until
you have both branches.
