Hi all, This series reworks some of the phylib code to allow PHY descriptions and connections to be extracted from the OF device tree. MDIO bus drivers gain a common helper function for parsing the PHY data and registering new phy_devices to match. Ethernet controller drivers gain the ability to resolve to a phy_device from a device tree phandle.
One notable aspect is that the Ethernet controller driver doesn't know if the phy_device is registered before or after the Ethernet driver. This series adds a function to the device model core code to make it simple for the driver to register a bus notifier (mdio_bus in this case), which gets called both for existing devices and for future device registrations. The advantage of this is that the driver doesn't need to know or care when the device actually shows up. It just knows that its callback will get called when the device is available. I think this is a good approach, but I'd appreciate some feedback on it.
