Some switch doesn't have a 1:1 map phy to port. Permit driver to provide a custom phy_mii_mask so the internal mdiobus can correctly use the provided phy reg as it can differ from the port reg. The qca8k driver is provided as a first user of this function.Why not have qca8k be in charge of allocating its internal MDIO bus like what mv88e6xxx or bcm_sf2 do? That would allow you to do all sorts of customization there and you could skip having patches 23 and 24.
Oh ok, I will implement the internal MDIO bus directly in the qca8k driver. Was thinking... Should I keep the extra mdio node and move the documentation to qca8k or should I handle all of that internally? To me it looks cleaner the direct definition in the devicetree than the port_to_phy function in the driver but as you can see extra checks are required to handle the new implementation and still supports the old one.
