But even with that, there is no reason why we could not decouple the
PHYLIB MDIO framework from PHYLIB and make it available as a more
standalone subsystem which can be utilized when you have a mix of MDIO
devices like here.
I am not clear on how common a shared MDIO bus is on other SoCs, but the
other Broadcom SoCs I am familiar with have dedicated MDIO buses
instances per type of PHY (PCIe, BUSB, Ethernet), thus making the split
a ton easier.
