If that is what we would desire. There are a few SR1.0 (not ES1.0)
examples for previous devices in [1]

NOTE: the dts in k.org will always point to the latest production SRx.y
device that has been released to market (aka products going to market).
previous pre-production SR support tends to be with overlays for various
quirks.

As appropriate for the subsystem.
