Hi Florian

Are you referring to:

        /* Include the pseudo-PHY address to divert reads towards our
         * workaround. This is only required for 7445D0, since 7445E0
         * disconnects the internal switch pseudo-PHY such that we can use the
         * regular SWITCH_MDIO master controller instead.
         *
         * Here we flag the pseudo PHY as needing special treatment and would
         * otherwise make all other PHY read/writes go to the master MDIO bus
         * controller that comes with this switch backed by the "mdio-unimac"
         * driver.
         */
?

Do you have an example device tree fragment, just to make it clearer?

Thanks
