    net: phy: Allow building mdio-boardinfo into the kernel · d0281a56
    Florian Fainelli authored
    mdio-boardinfo contains code that is helpful for platforms to register
    specific MDIO bus devices independent of how CONFIG_MDIO_DEVICE or
    CONFIG_PHYLIB will be selected (modular or built-in). In order to make
    that possible, let's do the following:
    
    - descend into drivers/net/phy/ unconditionally
    
    - make mdiobus_setup_mdiodev_from_board_info() take a callback argument
      which allows us not to expose the internal MDIO board info list and
      mutex, yet maintain the logic within the same file
    
    - relocate the code that creates a MDIO device into
      drivers/net/phy/mdio_bus.c
    
    - build mdio-boardinfo.o into the kernel as soon as MDIO_DEVICE is
      defined (y or m)
