This patch v2 avoids resource conflicts between the gianfar port instances by substituting dev_request_mem_region for dev_get_mem_region. In addition, it separates the MDIO buses from their Ethernet device by creating MDIO bus devices to access the external bus and TBI interfaces. This patch is tested on the P2020RDB for which there are 3 MDIO buses: - The main MDIO bus "gfar-mdio", linked to port eTSEC1 is used to connect external PHYs for all ports and map the internal TBI interface of eTSEC1. - The MDIO buses "gfar-tpiphy" map TBI interface registers on all remaining ports.
