-From be3687ac6bf12bd89059742faac2fb40ec8af419 Mon Sep 17 00:00:00 2001

-Subject: [PATCH 10/10] stmmac: fix MDIO settings
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Initially the phy_bus_name was added to manipulate the
-driver name but it was recently just used to manage the
-fixed-link and then to take some decision at run-time.
-So the patch uses the is_pseudo_fixed_link and removes
-the phy_bus_name variable not necessary anymore.
-
-The driver can manage the mdio registration by using phy-handle,
-dwmac-mdio and own parameter e.g. snps,phy-addr.
-This patch takes care about all these possible configurations
-and fixes the mdio registration in case of there is a real
-transceiver or a switch (that needs to be managed by using
-fixed-link).
