That checkpatch warning is known to have false positives in cases where
the binding says "<CHIPNAME>-device" or "device-<VERSION>". If you want
to update the binding to give an example with a version, that's fine,
but checkpatch shouldn't be why. We're not going to update the binding
example again to match a different version the next time one is added to
a device tree...

This is an example of why it's better to rely on version registers when
present.
