Subject: [PATCH v4 0/4] RTL9300 MDIO driver

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.

Chris Packham (4):
  dt-bindings: net: Add Realtek MDIO controller
  dt-bindings: mfd: Add MDIO interface to rtl9301-switch
  mips: dts: realtek: Add MDIO controller
  net: mdio: Add RTL9300 MDIO driver
