net: orion: generate unique port device names
Marvell Orion ethernet IP originally is multi-port capable, but SoCs using the IP usually have multiple single-port controllers built in. Currently, orion-gbe driver registers each port device with a constant name, which causes a name conflict with multiple controller instances. This patch uniquifies port device name generation by prepending controller's base register address to resolve the name conflict. Signed-off-by: Sebastian Hesselbarth <> Signed-off-by: Sascha Hauer <>
