The dpaa2-eth driver now has support for connecting to its associated PHY device found through standard OF bindings. This happens when the DPNI object (that the driver probes on) gets connected to a DPMAC. When that happens, the device tree is looked up by the DPMAC ID, and the associated PHY bindings are found. The old logic of handling the net device's link state by hand still needs to be kept, as the DPNI can be connected to other devices on the bus than a DPMAC: other DPNI, DPSW ports, etc. This logic is only engaged when there is no DPMAC (and therefore no phylink instance) attached. The MC firmware support multiple type of DPMAC links: TYPE_FIXED, TYPE_PHY. The TYPE_FIXED mode does not require any DPMAC management from Linux side, and as such, the driver will not handle such a DPMAC. Although PHYLINK typically handles SFP cages and in-band AN modes, for the moment the driver only supports the RGMII interfaces found on the LX2160A. Support for other modes will come later.
