And when it does, i guess it will be called microchip,ksz8995. See microchip,ksz.yaml.As it happens it does exist, so this was what I was using: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/net/micrel-ks8995.txt
Ah, that driver! O.K. I will take a second look at this. I suspect there is code in userspace actually driving the switch.
