I think I misunderstood the situation. I thought that the mdio register
space is separate from the network interface register space. So in
reality the mdio register space is inside the network register (the
TSEC) space, but one TSEC instance needs the mdio bus from the other
If that's the case then it's probably best to register a phy driver for
each phy in a coredevice_initcall like I suggested and then use
dev_get_mem_region in the phy driver instead of dev_request_mem_region.
