This series adds a driver for the MDIO controller on the RTL9300 family
of devices. The controller is a little unique in that we can't access the SMI
interfaces directly. This means we need to use the hardware description from
the DTS to compute a mapping of switch port to mdio bus/address.

The dt-bindings have been applied to net-next.

I've dropped a patch that added PHYs to the cameo-rtl9302c board as I know that
will need updating once some of the other in-flight changes make it into
linux-mips.
