Provide ability to specify a fixed phy in the device tree and retain the mdio bus if no phy is found. This is needed where a dsa is connected via a fixed phy and uses the mdio bus for config. Fixed ptp ref clock calculatins for the stmmac when ptp ref clock is running at <= 50Mhz. Also add device tree setting to config ptp clk source on socfpga platforms. Changes from V5: - Restore behaviour of unregister mdio bus when no phys found if there is no device tree node create the bus. - Modify condition to allocate mdio_base_data conditional on fixed phy presece as well. Maintains existing behaviour in conditions where a fixed phy is not present. Changes from V4: - Restore #ifdef CONFIG_OF around setting of reset_gpio. Member doesn't exist when this isn't defined. Changes from V3: - Use if (IS_ENABLED(CONFIG_OF)) instead of #if. Reorder some code to reduce if statements. - of_mdiobus_register already falls back to mdiobus_register - Tested on system with CONFIG_OF Changes from V2: - Formatting, spaces & lines > 80 chars. Using checkpatch - Drop PTP register debugfs patch. Changes from V1: - Fixed mismatch doc / code for ptp_ref_clk dt node. - Remove unit address from doc example.
