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.

Note that the dt-bindings: mfd patch is dependent on the dt-bindings: net patch.

Gmail seems to have decided to throttle mail coming from our domain so there
has been some things I've responded to that have hit lore.kernel.org but may
not have been delivered directly. So sorry if it looks like I've ignored
something. That's also why I haven't send this round out earlier as hopefully
we've done enough to get of Google's naughty list.
