Yes, I also think we should keep the drivers under sys/dev/, unless really
required otherwise. Even for the SoCs it's common to see their integrated
peripherals being shared between different models or even families, which
could be based on totally different CPU cores (or even architecture).

On a more general note: the sys/dev/ has long been a simple flat container
with everything in it, which is slowly making things more difficult with all
new architectures and peripherals coming into the tree. Has anyone
contemplated some reorganization of device drivers directory in a more
hierarchical fashion, so we could better manage similar classes of devices
from various vendors, have a bit more uniform naming scheme and so on?
