When the mdio-gpio driver is probed via device trees, the platform device id is set as -1, However the pdev->id is re-used as bus-id for while creating mdio gpio bus. So For device tree case the mdio-gpio bus name appears as "gpio-ffffffff" where as for non-device tree case the bus name appears as "gpio-<bus-num>" Which means the bus_id is fixed in device tree case, so we can't have two mdio gpio buses via device trees. Assigning a logical bus number via device tree solves the problem and the bus name is much consistent with non-device tree bus name. Without this patch 1. we can't support two mdio-gpio buses via device trees. 2. we should always pass gpio-ffffffff as bus name to phy_connect, very different to non-device tree bus name. So, setting up the bus_id via aliases from device tree is the right solution and other drivers do similar thing.
