This is just a simple switch, not an actual regulator.
It would make more sense to drop the voltage range and
instead have the implementation pass-through voltage

Please also add a device node for the actual Ethernet controller, and
set up an aliases node for it, so that the bootloader has some place
to fill in a MAC address.
