This MDIO HW is the same as the one GENET internally embedds, yet for historical reasons the two drivers lived their own lives. Because of the GENET interrupt situation, we let it specify how it wants to signal MDIO operations completion using its driver-private waitqueue. The diffstat is not super impressive, but it's still negative! This would make it easier in the future to absorb possible workarounds/bugs/features within the same location. This was tested on BCM7260 (GENETv5, single instance), BCM7439 (GENETv4, triple instance) and BCM7445 (bcm_sf2 + mdio-bcm-unimac). We also now have a nice /proc/iomem output: f0b00000-f0b0fc4b : /rdb/ethernet@f0b00000 f0b00e14-f0b00e1c : unimac-mdio.0 f0b20000-f0b2fc4b : /rdb/ethernet@f0b20000 f0b20e14-f0b20e1c : unimac-mdio.1 f0b40000-f0b4fc4b : /rdb/ethernet@f0b40000 f0b40e14-f0b40e1c : unimac-mdio.2 ==================== Signed-off-by: David S.
